1) Demonstrate Orion's Heat shield at lunar entry conditions, will be traveling at Mach 32, much faster than a return from LEO.  No test facility can simulate that.
2) Teams will verify all of @NASA_Orion's systems want to make sure that Orion can deal with the thermal challenges, and the engines can operate. Need to understand any uncertainties.
3) objective is to retrieve Orion after an ocean splashdown and do post-launch inspections
4) Certify the optical navigation system, deploy the CubeSats and share the mission with the public.
Mission planners have started to build detailed timelines. Looking at long class missions but objectives will remain the same 4 major burns  after TLI major burns, will also have two sets of burns to depart Lunar Orbit.
Sarafin also recalls this is a test mission, the team is prepared to adapt along the way, we may not have some time to certify the optical navigation system. Next few weeks will be a flurry of activity.

Interesting point from the briefing: if they roll out in August but don’t launch by Sept. 5, they have to roll back to the VAB to service the flight termination system, and may not be able to complete that & roll out in time for the next launch window (Sept. 20 _ Oct. 4)

Why does NASA only have 20 days to launch after activating the flight termination system? Answer is that FTS must be independent of rocket, operating on its own battery power. Those batteries have a limited lifetime. And since there is no fail safe, it is conservative.

[HOUSKEEPING NOTE]
This can be deleted whenever it's addressed, but I would like to note that the current HLV subforum may be confusing for newcomers: the "Missions to the Moon" section should have been for a while now where the threads concerning Artemis I and beyond are placed, but they somehow have been left in the heritage "HLV" section from the Constellation days (including Direct, Shuttle-derived HLVs and others... ??? ) even after the program is about to launching its first mission to the Moon.
In fact, the "Missions to the Moon" section's description reads: "Forum section dedicated on HSF Missions To The Moon (EM-1 etc)". As well all know, Exploration Mission-1 is the technical designation of Artemis I before the program had a proper name.

Ahead of the Artemis I flight test, NASA is inviting media to its Johnson Space Center in Houston Friday, Aug. 5, for a detailed mission briefing and a behind-the-scenes look at facilities that will enable a long-term human presence at the Moon.

NASA is currently targeting no earlier than Monday, Aug. 29, for the launch of the Space Launch System rocket to send the Orion spacecraft around the Moon and back to Earth. The mission will take place over the course of about six weeks to check out systems before crew fly aboard on Artemis II.

The media day will feature mission support facilities, trainers, and hardware for future Artemis missions, as well as interview opportunities with program leaders, flight directors, astronauts, scientists, and engineers. It also will feature tours and activities in unique facilities at Johnson.

U.S. media interested in participating in person at Johnson must contact the Johnson newsroom no later than 5 p.m. Friday, July 29, by calling: 281-483-5111 or emailing: [email protected] International media must contact the Johnson newsroom no later than 5 p.m. Tuesday, July 26.

Planned activities include:

    In-depth mission briefing – Discuss the Artemis I mission profile with flight directors and mission experts. The briefing also will air on NASA TV and media may ask questions by phone. NASA will share the briefing time and details to join by phone at a later date.

    Artemis mission control – Chat with flight directors, engineers and astronauts while in the control room that will be used throughout the Artemis I mission.

    Space Vehicle Mockup Facility – View a full scale version of the Orion crew module used for training and an Orion launch and entry suit that will be worn by astronauts on future Artemis missions.

    Systems Engineering Simulator – Preview the first Artemis lunar surface excursions in a new virtual reality trainer that is preparing future moonwalkers for extravehicular lunar surface operations.

    Neutral Buoyancy Laboratory – Learn about the latest hardware and ongoing testing in one of the world’s largest swimming pools to support Artemis missions.

    Gateway high-fidelity hardware mockup fabrication facility – Tour a high-fidelity mockup of Gateway’s Habitation and Logistics Outpost module where Artemis astronauts will live and work during future Artemis missions.

    Additional interview opportunities – Speak with experts from various programs at Johnson that support NASA’s Artemis missions, including the Extravehicular Activity and Human Surface Mobility Program and the Commercial Lunar Payload Services initiative.

Artemis I is an uncrewed flight test, the first in a series of increasingly complex missions to the Moon in preparation for human missions to Mars. Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars.

I've read that the proper time of day for the first launch of SLS has been contingent upon the alignment of the Earth and Moon, so how does the tentative time of day for August 29 correlate with the Earth-Moon alignment for that day?

... how does the tentative time of day for August 29 correlate with the Earth-Moon alignment for that day?
I've not seen the details explained anywhere.

FWIW, plugging LC-39B's location into mooncalc.org, I get the following moonrise times and range of lunar altitude and azimuth for the three launch dates and windows.  (Times in EDT = UTC-4):
2022-08-29 Launch: 08:33—10:33  Moonrise: 08:58  Altitude: -6°—+19°  Azimuth: 084—099 (Waxing crescent/5%)
2022-09-02 Launch: 12:48—14:48  Moonrise: 12:59  Altitude: -3°—+19°  Azimuth: 112—129 (Waxing crescent/39%)
2022-09-05 Launch: 17:12—18:42  Moonrise: 16:17  Altitude: +9°—+22°  Azimuth: 128—143 (Waxing gibbous/74%)

The moon ranges from being slightly below the horizon to low on the horizon during the launch windows.
I've not heard an explanation for why the third launch window is half an hour shorter than the other two.
(Edited to add that 30 minutes before the start of that final, shorter window, the moon is +4° @ 124.)

ESA names first ‘astronaut’ to fly on the Artemis I lunar mission
02/08/2022

The specially trained woolly astronaut, Shaun the Sheep, has been assigned a seat on the Artemis I mission to the Moon. Shaun’s assignment was announced by ESA’s Director for Human and Robotic Exploration Dr David Parker.

David Parker said, “Shaun’s mission assignment rounds off the first phase for the latest members of our astronaut corps, with Italian ESA astronaut Samantha Cristoforetti currently on the International Space Station on her second spaceflight, Danish ESA astronaut Andreas Mogensen named for his second flight and before we introduce our new astronauts from the 2021 call for selection later this year.”

“This is an exciting time for Shaun and for us at ESA. We’re woolly very happy that he’s been selected for the mission and we understand that, although it might be a small step for a human, it’s a giant leap for lambkind,” added David Parker.

Shaun will be flying on the Artemis I mission, which will be the first flight of NASA’s Orion spacecraft with an ESA European Service Module, planned to go around the Moon and back. This mission is not carrying a human crew but will instead be controlled from the ground with its woolly specialist as a passenger.

Orion and its European Service Module will be launched by the Space Launch System from the Kennedy Space Center in Florida, USA. The spacecraft will enter a low-Earth orbit before the rocket’s upper stage fires to take it into a translunar orbit.

The spacecraft will perform a flyby of the Moon, using lunar gravity to gain speed and propel itself 70 000 km beyond the Moon, almost half a million km from Earth – farther than any human, or sheep, has ever travelled.

In preparation for this flight, Shaun began a programme of astronaut training and familiarisation with the Orion spacecraft and its European Service Module in 2020, travelling to various locations across Europe and the USA to see different aspects of the mission. This training was documented and will be presented in a series of ESA blog posts leading up to launch.

With a keen passion for exploring, Shaun took flight on the special Airbus ‘Zero G’ A310 aircraft during one of its parabolic flights that recreates the ‘weightless’ conditions similar to those experienced in space.

Under the supervision of an ESA team, this flight prepared Shaun for his role as a space traveller in his film ‘A Shaun the Sheep Movie: Farmageddon’, released in 2019. It offered insight into the rigorous training that all astronauts undertake to prepare for spaceflight, which he will now experience for real.

Lucy Wendover, Marketing Director at Aardman says, “Aardman is excited to be joining ESA in making history by launching the first ‘sheep’ into space. As one of the first astronauts to fly an Artemis mission, Shaun is leading the way in lunar exploration, a great honour for our woolly adventurer! 2022 marks the 15th anniversary of Shaun’s first TV series, so what better way to celebrate than by travelling farther than any sheep has gone before.”

The kit doesn't give a schedule for cubesat deployments (there is a diagram with A, B, C deployments, but not which cubesats are included in each deployment).  Is that information available anywhere?

EDIT:  Argomoon will be deployed in the first batch, per a presentation at the NASA Exploration Science Forum in July.  That's all I have so far.

Here's that briefing on YouTube:
https://youtube.com/watch?v=37tnhg4H5Xo

About 25:12 in the video there is an interesting section from the LD about the status of SLS and Orion in the VAB, as well as the remaining work items before rollout. Rollout is targeted to start of August 18, will be 11 day rollout campaign (including getting everything ready on the launch tower etc)

Remaining items:
- complete loading of items into Orion, door will be closed in 10 days
- flight termination system test next week, required access to parts of core stage and boosters that can't be closed out yet
- small bit of work on right booster thermal skirt close out
- retracting remaining work platforms, 3 are already retracted
- full launch simulation in control room (she said tomorrow when video was recorded)

Interesting note that extra hour of hold was added to launch timeline due to finding in WDR that existing hold wasn't enough to complete everything on time.

Ten shoebox-size secondary payloads, called CubeSats, are hitching a ride to space on Artemis I’s Space Launch System (SLS) rocket, and several other investigations are flying inside the Orion spacecraft during the flight test. Each of the payloads will perform science and technology experiments in deep space, expanding understanding of lunar science, technology developments, and deep space radiation.

Audio of all three briefings will livestream on NASA’s website. The briefings include (all times Eastern):

Monday, Aug. 15

5 p.m. – Lunar science payloads teleconference with the following participants:

Dr. Jacob Bleacher, NASA chief exploration scientist

Artemis I Path to the Pad: The Rocket

Quote
Have you ever wondered what it takes to assemble the most powerful rocket NASA has ever built? Watch documentary footage of our Space Launch System (SLS) rocket's transformation into the over-300-foot-tall launch vehicle that will return humanity to the Moon.

Starting with manufacturing and ending with stacking operations inside NASA Kennedy Space Center's Vehicle Assembly Building, this is only the beginning of SLS's path to the pad.

Skylab only needed a month on the pad.  It was the Apollo Spacecraft that needed servicing at the pad.  Orion is serviced offline

Stowaways on NASA’s massive Moon rocket promise big science in small packages (https://www.science.org/content/article/stowaways-nasa-s-massive-moon-rocket-promise-big-science-small-packages)

Quote from: Science
The investigators who built those satellites have more than the usual launch jitters: Half of them may not have enough power to begin their missions. Stuck within the rocket for more than a year because of launch delays, their batteries have drained to a level where some may be unable to boot up and unfurl their solar panels. “The longer we wait, the higher the risk,” says Ben Malphrus of Morehead State University, principal investigator for Lunar IceCube, one of the CubeSats with power concerns.

<snip>

BioSentinel, NEA Scout, and three other CubeSats were allowed to recharge their batteries during their long wait aboard the SLS. But five others were out of luck, including both LunaH Map and Lunar IceCube. Some could not be recharged without removing them from the rocket; in other cases NASA engineers feared the process might spark discharges that could harm the rest of the rocket. “We have to be very cognizant of the risk to the primary mission when we interface with these CubeSats,” says Jacob Bleacher, NASA’s chief exploration scientist.

Also Jeff Foust said this is known for a few months but nobody wants to talk about it, not a good look for a public program which is supposed to be more transparent than private programs:

LIVE: Dawn of Artemis (Literally, a sunrise Q&A stream)
19 Aug 2022

The Space Launch System (SLS) rocket sits on pad 39b, waiting for it's chance to shoot for the moon on the Artemis 1 mission. SLS, the most powerful rocket ever built by the space agency, is scheduled to launch the Artemis-1 mission on Aug. 29, sending the human-rated Orion spacecraft on an uncrewed flight test around the moon.

NASA Sets Launch Coverage for Artemis Mega Moon Rocket, Spacecraft

NASA will provide coverage of prelaunch, launch, and postlaunch activities for Artemis I, the first integrated test of NASA’s Orion spacecraft, Space Launch System (SLS) rocket, and the ground systems at the agency’s Kennedy Space Center in Florida. This uncrewed flight test around the Moon will pave the way for a crewed flight test and future human lunar exploration as part of Artemis.

The SLS rocket is targeted to launch during a two-hour window that opens at 8:33 a.m. EDT Monday, Aug. 29, from Launch Pad 39B at Kennedy.

The rocket and spacecraft arrived at its launch pad Wednesday after the nearly 10-hour, four-mile trek from the Vehicle Assembly Building. A livestream of the rocket and spacecraft at the launch pad currently is available on the NASA Kennedy YouTube channel.

Live coverage of events will air on NASA Television, the NASA app, and the agency’s website, with prelaunch events starting Monday, Aug. 22. The launch countdown will begin Saturday, Aug. 27, at 10:23 a.m.

A live broadcast of the launch also will include celebrity appearances by Jack Black, Chris Evans, and Keke Palmer, as well as a special performance of “The Star-Spangled Banner” by Josh Grobin and Herbie Hancock. It also will feature a performance of “America the Beautiful” by The Philadelphia Orchestra and cellist Yo-Yo Ma, conducted by Yannick Nézet-Séguin.

The first in a series of increasingly complex missions, Artemis I will be an uncrewed flight test that will provide a foundation to extend human presence to the Moon and beyond. The mission will demonstrate the performance of the SLS rocket and test Orion’s capabilities over the course of about six weeks as it travels about 40,000 miles beyond the Moon and back to Earth.

A limited number of seats inside the auditorium at Kennedy will be available to on-site journalists on a first-come, first-served basis. The deadline has passed for media accreditation for in-person coverage of this launch. Additional journalists wishing to participate may dial in. To participate by telephone, media must RSVP no later than two hours before the start of each briefing to: [email protected] Media and members of the public may also ask questions on social media using #Artemis.

Track NASA’s Artemis I Mission in Real Time
NASA's AROW app
Using AROW, almost anyone with internet access can pinpoint where Orion is and track its distance from the Earth, distance from the Moon, mission duration, and more.

Join NASA’s Orion spacecraft on its first mission around the Moon using the Artemis Real-time Orbit Website (AROW) to track the spacecraft’s flight as it happens.
NASA's AROW app
On the web, users can follow AROW to see where Orion is in relation to the Earth and the Moon and follow Orion’s path during the mission.

During Artemis I, Orion will travel to 40,000 miles beyond the Moon in the first integrated flight test with the Space Launch System (SLS) rocket. Using AROW, almost anyone with internet access can pinpoint where Orion is and track its distance from the Earth, distance from the Moon, mission duration, and more. AROW will be available beginning Aug. 28 on NASA’s website and on the @NASA_Orion Twitter account.

AROW visualizes data collected by sensors on Orion and sent to the Mission Control Center at NASA’s Johnson Space Center in Houston during its flight. It will provide periodic real-time data beginning about one minute after liftoff through separation of the SLS rocket’s Interim Cryogenic Propulsion Stage approximately two hours into flight. Once Orion is flying on its own, AROW will provide constant real-time information.

“This is a really powerful way to engage with the mission and understand the scope of what NASA is trying to accomplish with Artemis I,” said Seth Lambert, the Orion programmer who created AROW.

On the web, users can follow AROW to see where Orion is in relation to the Earth and the Moon and follow Orion’s path during the mission. Users can view key mission milestones, and characteristics on the Moon, including information about landing sites from the Apollo program. Also available for download will be trajectory data from the flight, called an ephemeris.

AROW also will provide a set of Orion’s state vectors — data that describes precisely where Orion is located in space and how it moves — for inclusion in these tweets once Orion is flying on its own. These vectors can be used for data lovers, artists, and creatives to make their own tracking app, data visualization, or anything else they envision.

“Knowing what the spacecraft is doing during the mission is already cool, but now that Orion’s data can be visualized in all these different ways, it will be interesting to see what creative projects others come up with,” said Richard Garodnick, an engineer on the mission control center system engineering and development team at Johnson.

And while the app was developed and will be used for Artemis missions, the technology behind AROW could be applied to other missions in the future.

Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars.

Artemis I managers conduct a Flight Readiness Review (FRR) on Aug. 22, 2022, at NASA’s Kennedy Space Center in Florida. The FRR is an in-depth assessment of the readiness of the agency’s Space Launch System and Orion spacecraft to support the uncrewed flight of Artemis I on its mission beyond the Moon and return to Earth. The meeting will conclude later in the day with a poll of all managers. Artemis I is scheduled to launch at 8:33 a.m. EDT on Aug. 29, 2022, from Kennedy’s Launch Complex 39B. The first in a series of increasingly complex missions, Artemis I will provide a foundation for human deep space exploration and demonstrate our commitment and capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the integrated systems before crewed missions by operating the spacecraft in a deep space environment, testing Orion’s heat shield, and recovering the crew module after reentry, descent, and splashdown.

Important note from Charlie Blackwell-Thompson.

In other words, do not be surprised if there are scrubs during the initial attempts. Might launch the first time, but it'd take a lot to go right.

As ready as we are to fly, it's important to stress Artemis I is a flight test. We've engineered with rigor, but even the best models and tests aren't full-proof. As part of our review today, we discussed managing expectations, recognizing things may not go to plan. However, our team is agile, and they are prepared for what space may throw at them as we push our vehicle to its limits.

Reviews like the one we had today are meant to bring about critical discussions and provide checks and balances to our processes. This mission has risk. Spaceflight, much like life, requires us to be bold, to take certain risks. We are willing to take these risks because we have worked to understand them, mitigated them as far as we can, and as a result, accepted them. However, it's only through taking calculated risks that we will get to the Moon. Proud of our teams' work to get us to today, for the risk they've worked to understand, and for always leaning forward.

We are ready.

Superb article by William Graham on the Saturn rockets' heritage!  In a sense, Artemis 1 is an "All-Up" Test akin to Apollo 4.  Granted the SRBs, RS-25s, upper stage, etc. have flown before.  If NASA had an Apollo-scale budget, would the agency have flown the core stage first with expendable RS-25s a dummy upper stage on a suborbital trajectory?  Probably no need to do this type of testing these days.  I hope the Apollo engineers living today can take pride in the foundations they laid.

From Apollo to #Artemis. The test flights are different but the goal is the same: Go to the Moon. So just how do the Apollo & Artemis flight test campaigns differ? How are they similar?

While it's not the same as a launch forecast, today's Weekly Planning Forecast issued by the 45th Weather Squadron for CCSFS & KSC shows a 70% precipitation probability and 40% lightning probability for the AM period of Monday, August 29. I would expect their first (L-3 days) Artemis I launch forecast to be issued some time tomorrow.

Teams have completed the retraction of the Crew Access Arm (CAA), putting it into launch configuration for #Artemis I. While @NASA_Orion is uncrewed on this first mission - the CAA, at the 274-ft level on the mobile launcher, provides entry and emergency egress to the spacecraft.

Prelaunch coverage of the Artemis I flight test continues on Sunday, Aug. 28 at 9 a.m. EDT (12:00 UTC) as experts discuss the countdown status. Hear from:

  Jeff Spaulding, Artemis I senior NASA test director
  Melody Lovin, weather officer, Space Launch Delta 45

During the #Artemis I flight test, an uncrewed Orion spacecraft will lift off aboard the Space Launch System (SLS) rocket, and travel 280,000 miles (450,000 km) from Earth and 40,000 miles (64,000 km) beyond the far side of the Moon, carrying science and technology payloads to expand our understanding of lunar science, technology developments, and deep space radiation. This mission will pave the way for a crewed flight test and future human lunar exploration as part of Artemis.

Countdown Continues, Teams Confirm No Impacts from Lightning Strikes

NASA Posted on August 28, 2022 10:55 am

Overnight engineers evaluated data from lightning strikes to the lightning protection system at Launch Pad 39B that occurred yesterday. They confirmed the strikes were of low magnitude and had no impacts to Space Launch System, Orion, or ground systems.

Meteorologists with the U.S. Space Force Space Launch Delta 45 predict an 80% chance of favorable weather conditions at the beginning of the two-hour launch window that opens at 8:33 a.m. EDT Aug. 29, with a 60% change of favorable weather conditions toward the later part of the window. The primary weather concern for the two-hour launch window remains scattered rain showers. The weather guidelines for NASA’s Artemis I flight test identify conditions to launch the agency’s Space Launch System and Orion spacecraft.  

Overnight teams also powered up the Space Launch System rocket’s core stage, charged Orion and core stage batteries, and conducted final preparations on the umbilicals. A pre-launch walkdown are continuing at the launch pad this morning. Teams will continue working their way through the countdown today, including powering up the interim cryogenic propulsion stage, conducting planned health checks on Orion systems,

Live coverage of tanking operations will begin at midnight on NASA television, the agency’s website, and the NASA app. Full launch coverage begin at 6:30 a.m. EDT on NASA Television and the agency’s website, as well as YouTube, Twitter, Facebook, LinkedIn, Twitch, Daily Motion, Theta.TV, and the NASA app. 

The uncrewed flight test will test SLS and Orion as an integrated system, demonstrating the performance of the rocket and testing the spacecraft’s capabilities as it journeys about 40,000 miles beyond the Moon over the course of about six weeks.

The first in an increasingly complex series of missions, Artemis I will pave the way for long-term lunar exploration, providing the foundation for extending human presence to the Moon and beyond.

Interesting note from the SLS briefing this morning. If the count reaches main engine ignition, at T-6.8 seconds, and there is a scrub for any reason they will not be able to recycle. Rocket will need to go back to VAB for an engine swap.

Why is this? Because after engine ignition there are a bunch of inspections needed before firing them again. Easier to swap out RS-25s. Working with hydrogen is hard.

Mission Management Team “Go” to Proceed with Tanking for Artemis I Mission

The Artemis I Mission Management Team has given the “go” to proceed toward tanking operations.

Weather conditions remain 80% favorable at the beginning of the two-hour launch window which opens at 8:33 a.m. EDT Aug. 29, with chances for rain showers increasing toward the later part of the window.

Artemis I launch director Charlie Blackwell-Thompson is scheduled to give the “go” to officially begin propellant loading operations just before midnight.

During tanking operations, teams will fuel the Space Launch System (SLS) rocket with liquid oxygen (LOX) and liquid hydrogen (LH2), beginning with the rocket’s core stage and then the interim cryogenic propulsion stage.

Tanking begins with chilling down the LOX lines for the core stage. The process for the chill down, or cooling, uses the propellant lines to load the rocket’s core stage LOX in preparation for tanking. The LOX tank holds 196,000 gallons of liquid oxygen, cooled to minus 297 degrees Fahrenheit. In sequential fashion, LOX and LH2 will flow into the rocket’s core stage tank and be topped off and replenished as some of the cryogenic propellant boils off.

The process involves slowly filling the core stage with propellant to thermally condition the tank until temperature and pressure are stable before beginning fast fill operations, which is when the tank is filled at a quicker pump speed. As the super cold liquid oxygen fills the core stage tank, some venting may be visible. The team also will conduct leak checks to ensure propellant loading is proceeding as expected.

At midnight, NASA TV coverage begins with commentary of tanking operations to load propellant into the SLS rocket. Full coverage begins at 6:30 a.m. in English and at 7:30, coverage in Spanish begins.

Below are the countdown milestones as planned for tanking:

Core Stage LO2 transfer line chilldown (L-8H15M – L-8H)
Core stage LO2 main propulsion system (MPS) chilldown (L-8H – L-7H20M)

One constraint to launch, but not to tankin , is a comm issue  with Orion. Both channels are working now, but there had been an 11 minute delay on one of them and they're trying to figure out why.

While the MMT is go, Launch Director Charlie Blackwell-Thompson is yet to give the official go for tanking. Weather has turned for the worse in the area. Lightning will be the concern.

Also working on a telemetry channel issue with Orion.

Derrol Nail, NASA Communications, reporting now on the NASA public feed for Artemis Launch Control:
- Launch Weather Officer: 30% chance of violation inside a storm cell drifting toward the pad.
- Team working ahead on some items not related to cryo loading.
- First hour of tanking is highest risk for lightning concerns.

SLS/Artemis 1: If so, they will resume fast fill, loading LH2 at a 10x faster rate, and see if the concentration goes back up at the higher pressure; if it goes past 4% they will stop fast fill, revert, and do more troubleshooting (2/2)

Back on LH2 stop fill. Had an over pressure alarm go off on line feeding LH2 tank. Working on troubleshooting this. Quite possible line has warmed up, causing flashing in line. LO2 continues and is 47% full. Could be butting against aft strut constraint. LH2 tank has to be above 5% for LO2 to continue above 50%.

L minus vs T minus

https://www.nesdis.noaa.gov/news/top-5-terms-you-should-know-satellite-launch

L- (pronounced "L minus”) refers to the days, hours, and minutes remaining in the scheduled countdown to launch, which occurs at L-0. The “L” stands for launch.

T- (pronounced "T minus”) refers to the time remaining on the official countdown clock. The “T” stands for time. During planned holds in the countdown process (when the countdown clock is intentionally stopped), the T- time also stops. The L- time, however, is synced to the clock on the wall and continues to advance.

Currently performing engine bleed. Running LH2 through engines to condition them for launch. They got good bleed for three of the engines, but not getting correct bleed for engine number 3. Trying pressurising the tank to get the bleeds flowing better. LH2 is now closed and in revert, draining tank so as to perform engine bleed.

Engine number 3 still not at required temperature. Tried cycling the bleed and pressurising the tank. Will try closing overflow bleed valve to let all four engines warm up a little and then open the bleed again, hoping this will equalise the temperatures across the engines and then get the temperatures to drop. With the propellant have a faster flow across those engines. They were not getting they needed on No.3 because they don't have the right pressure and flow.

Also looking at a line of frost formation on the intertank. Trying to determine what that is, whether it might be a crack in the TPS or if there's something going on with the tank. Engineers are evaluating.

Line of ice that had formed on intertank on exterior of core stage. Concluded that it formed along a line of air that had been chilled by the tank in a crack in the foam, but not into the tank. A stress crack in the foam. Would see an offset if there was a structural crack. Have a history of this with Space Shuttle tank. Called cryopumping.

NASA Waves Off First Artemis I Launch Attempt, to Provide Media Update

Following the Artemis I launch scrub Monday from Launch Complex 39B at NASA’s Kennedy Space Center in Florida, the agency will hold a media briefing at approximately 1 p.m. EDT today, Monday, Aug. 29, to discuss mission status.

The briefing will livestream on NASA Television, the agency’s app, and on the agency’s website.

Artemis I is a flight test to launch NASA’s Space Launch System rocket and an uncrewed Orion spacecraft around the Moon before the Artemis II mission with astronauts aboard.

The approximately two-day countdown for launch began Saturday, Aug. 27, and was waved off Monday after encountering an issue getting one of the four RS-25 engines on the bottom of the rocket’s core stage to the proper temperature range for liftoff.

NASA Administrator Bill Nelson provided brief remarks shortly after the scrub was announced. He also will join the upcoming news conference.

The following individuals also are confirmed to participate at this time:

Jim Free, associate administrator for Exploration Systems Development Mission Directorate, NASA Headquarters
Mike Sarafin, Artemis mission manager, NASA Headquarters
To participate by telephone, media must RSVP by the start of the call to: [email protected] 

Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars.

NASA will host a teleconference tomorrow, after the meeting to decide the path forward.

Mike Sarafin summarizes events since the previous press conference.

New-ish news?  Verification of Orion flight software occurred, but with an 11 minute delay.  Misconfiguration: one of the Orion command and control modules off.  Proper configuration solved issue.

BILL NELSON:  Proud of these teams preparation and work to get to today.  This rocket will not fly until it's ready.  Needless to say, it's complexity is daunting when you bring it all into focus of a countdown.  Vice President was here, she is very bullish when it comes to our space program.  She was here earlier, toured the O&C Building and saw the Artemis hardware there.  Overall, she had a very productive visit, and I would expect that you will see her at a future launch.  Understand that scrubs are just a part of the program.  On the spaceflight I participated in, Hoot Gibson and I scrubbed 4 times on the pad.  It was the better part of a month.  Looking back, after the 5th try and getting off to a successful mission, it would NOT have been a good situation if we tried to launch during one of those scrubs.  You want to identify the risks, stress it, and fix the risks.  That is the goal of Artemis 1.  Stress it, try it, and fix it so Artemis 2 is safe when we put astronauts onboard.

----

MIKE SARAFIN: The technical issues that the teams have overcome have been great.  We found one that we need more time to look into.  The last 48 hours have been very dymanic.  The launch team entered the countdown on Saturday morning... Saturday morning, we got two lightning strikes at the pad.  The teams quickly found that there were no issues to proceed with the count.  We also then closed out an action in the L-2 MMT checklist, that verified communications coverage with the rocket.  Tanking meeting on Sunday, we came in at 2150 EDT to reassess the readiness to load the vehicle with cryo - we were GO.  And we were go with the weather forecast, 20% lightning, 40% precip, during tanking.  During that time, the team ran into an issue with the flight software.  Took 11 minutes to verify, once it was verified, we proceeded.  Shortly after the GO for tanking, we went into a lightning alert which delayed loading by an hour.  Once we began filling, we ran into a leak at the 8in QD (fill/drain).  This happened at fast-fill.  Team diagnosed, slowed the rate, and were able to successfully tank from there.  Forwarding to the engine bleed, we noticed engine 3 was not properly chilling.  Teams began investigating, and then noticed a leak at the intertank.  Between not getting the engine chilled, plus trying to explore the leak at the intertank, we decided it was best to scrub today, gather data, and allow the teams to rest.  We will reconvene tomorrow at 1500 EDT to see what options we have available, and will update the media tomorrow (30 Aug) evening.  Today was a challenging day - had 42 collision avoidance cutouts that we had to work through, most just a couple of seconds, but a few were minutes long.  When you understand how complex this mission and program are, you have to know where all of the space debris is as we fly through the path twice to get to TLI.

----

JIM FREE: We're in the LCC, and I found some things in the team today - after WDR #4, there were some questions on whether we should rollback, or things we should change, and we felt that pushing for today was the right move and still do.  Team today was stressed and compressed with a tight timeline, filling all 4 tanks at one point.  Pushing through a weather timeline, we were not able to go at the start of the window like we thought, weather was coming in and out.  Mike talked about going to manual control - when we went to LOX the first time, going to manual control is learning to me.  The leak kept growing, and we got out of it by switching to manual control.  I know we continue to talk about the team, but we all continue to learn.  Bob Cabana said it best, we test the people and the machine during these times.  Charlie extended the timeline by about an hour, which definitely helped us to look at data.  We talked about engine 3 not being where we wanted, but all 4 engines really weren't exactly as cold as we wanted.  We will NOT have all the data and implications today, but we wanted to share all of this with you today while it is fresh.  Trust us, there's no other group that wanted to get through this successfully but the folks behind the console!

Post by: Ford Mustang on 08/29/2022 05:21 pm
Q - Is Friday or Monday feasible since you're dealing with an engine?  Might you need to replace this engine, but you also said you didn't get the temps as low, what's worst case?


A - MIKE: Friday is definitely in play, but need to look at data.  Team is setting up for 96 hour reset.  Preserving options, replenishing commodities at LC39.  Indications don't point to an engine issue, more to a bleed-system issue.  Changed the diameter of that from Stennis testing (made it bigger).  Never fully got into the bleed config through prior wet-dress testing.  We knew it was a known risk, and said we would not launch unless we got through the demonstration to thermally condition the engines.  Just didn't get there today.
JIM: We stayed loaded longer to try to figure it out, trying to save as many cycles on the tank as we can.
-----
Q - Friday is in play, but given the magnitude, is it likely to launch Friday, or unlikely?  Can you clarify if this is close to the QD issue found in WDR's?

A - There's a nonzero chance that we will have a launch opportunity on Friday.  We need time to look at the data, we're going to play all 9 innings, just need time to look at the data.  During WDR, we saw issues at both the 4in and 8in QD in terms of ability to retain enough pressure to properly seal.  Never got to the engine bleed itself.  The QD problems during the wet test have largely been mitigated.  The 8in today was the issue, had a little bit of leakage that we were able to work through by slowing fill and chilling.  We got a full load in, were not able to do that during the first 3 WDR's.  4in QD worked fine today.  Feel like they did not play into the engine bleed issue today.
----
Q - Possibility of a rollback?  How likely, based on data?  If you were to roll back, what does that do to the timeline?


A - That's getting ahead of our data reviews.  We need the team to get rested and reassess tomorrow to see what the data tells us.  Nonzero chance, but we will do our best to see where the data leads us.  If we can resolve this operationally, no rollback needed.  If we can resolve this within the next 48-72 hours on the pad, Friday is good.
----
Q - Can you give us a quick insight into how the bleed system works?  What was changed, why?

A - Deferring to John Honeycutt tomorrow, I know we increased the diameter of the bleed to the engines, but that question is outside of my experience base.
-----
Q - Mentioned intertank vent issue, can you provide more insight into that?  If you had no issues with engine 3, would that have been a violation?


A - Leak at the vent valve.  Want to increase the pressure in the tank, and the vent valve wasn't working with us to establish the correct bleed.  Engine 3 was not seeing the correct temps, the vent valve wasn't helping that issue, and the team decided that it was best to scrub based on the fact that we needed more time.
-----
Q - You mentioned you didn't see temps on all 4 engines that you were anticipating, but 3 is the focus.  Can you explain?

A - Other 3 engines were meeting the trend to be at the right temperature, but were not there yet.  Engine 3 was not trending at all.
-----
Q - What is the temperature that you need the RS-25 to be at to launch?  How far away were you?  How did you fix Hydrogen leak?

A - Temps should be around 500 Rankin on the engines before they are thermally conditioned.  1, 2, and 4 were close to that.  3 was just not getting there.  Hydrogen leak... incredibly small molecule.  Sometimes the QD takes a bit of a cold soak, if there's a temperature difference, it can cause a bit of a leak.  Cryo team is very experienced with this, and they recommended to stop flow, then slowly increased it through manual flow procedures.  Slowly letting it through, gave good time to thermally condition both sides.  That happened today, had to tow the delicate balance.  Want to fill as fast as you can to meet timeline, but sometimes you have to slow it down to make everything work.  A little science, a little art, to make it happen.
----
Q - You were confident in running a full countdown vs WDR.  Any risks associated?


A - We would introduce risks by just rolling out for a WDR.  Felt like we addressed the leak issues from WDR 4.  Had a leak today, but worked through it, so I'm still confident in today's decision.
----
Q - Done effectively 5 WDR's, can you walk me through why it wasn't prudent for today to be a WDR vs full countdown?

A - Another cycle of rolling out and back.  Going to learn every time we come out here, going back through history, looking at Apollo and their scrubs, how many times Shuttle scrubbed.  We're going to run into these issues, and we'll figure it out together.  If we came out for another WDR, the vehicle would not have been closed out and ready to go - we learned about our FTS system, working with the range to get a 25 day retest, etc.  Felt like we were in the best position to try today.
-----
Q - Were you surprised or disappointed with how things went today?

A - JIM: Plan a week trip to Florida for a vacation, you might see a launch.  Exactly what I told my family.  We're going to launch when we're ready, and that's our approach.  Nobody came here and wanted this to happen more than the launch team that was here, and everyone wants it to be successful.  Our job is to make it as successful as we can.  We might get to another one, and might have other issues... might decide not to fly.  That's the most important decision we can make.
MIKE: We all want to see that next milestone, that next step.  Seeing smoke and fire, that's what everyone wants.  But we won't let this hurdle discourage us from that next step.  We're doing this with a lot of new - controllers, people, software.  We're learning all the way.  One of the things that we love is that this is a learning organization.  We've applied a lot of lessons learned, this is another.  It won't deter us from achieving the next step.
----
Q - Flight controllers came up with a couple plans to fix the engine issue - can you give us some insight into the control room when this was going on?

A - Yes, there were "pre-planned" procedures that the team has for issues, such as the leak on the 8in QD.  Team worked through those very efficiently and methodical.  Team had to have a delicate balance of filling the tanks as fast as they could to meet launch rate, but slow enough to not spring another leak.  Team was very methodical.  When we ran into the engine bleed condition, they noted it, worked through the fact that 3 out of 4 engines looked pretty good on thermal conditioning.  Tried some steps, consulted engineering teams (Boeing, Aerojet Rocketdyne), worked efficiently as a team.  Quite a bit of chatter when we were outside of the pre-planned contingency, but just were not successful with the intertank vent-valve issue and managing pressure.  Teams then shifted focus to keep pressures within designed limits, and then ultimately led to a scrub.
JIM: Teams went to anomaly loop, asked for more times, are able to run through simulation loops and gather data that way.  NASA Test Director and Launch Director trying to manage the flow, have to make sure to stay on the timeline.
-----
Q - Does today give you a new appreciation, or hearken back to, what your predecessors went through 50+ years ago?  How do you juxtapose today versus then?

A - JIM: Randy Bresnik said it best - they didn't know it could be done, which is more impressive.  Today, we know it's possible.  Makes Apollo more impressive because they didn't know.  Shuttle, ISS, everything we've done is impressive.  I know the team today will get through it, and they're inspired because they've seen it done.
BILL NELSON: They went step by step.  Apollo 7, then 8 which was around the moon, then 9 that tested docking in LEO.  We are coupling all 3 of those missions in Artemis 1.  Then they went into Apollo 10, then 11, and that was the part of what is going to be Artemis 2 and 3.  It's a compression of a lot of things, and we're standing on the shoulders of those that have been there before, with a brand new vehicle.  Very impressive.
-----
Q - You talked about the issue being on the core side, not the engine side.  Can you elaborate?  Talked to Boeing yet?

A - We did discuss whether or not there was an engine problem.  Do we need to R/R the engine?  No indications of that yet.  Boeing is part of our engineering team, they're on our Mission Management Team.  They were in the LCC today.  We have tapped their expertise, and the expertise of those in our sister sites.  Had a lot of people weigh in, and at the end of the day, didn't run into just one issue, but a compounding issue that we all decided we needed more time on.
----
Q - is there something about the position of engine 3 that makes it susceptible to this issue?  Could this have happened to another engine?

A - Honeycutt has asked his team to go look at this.  We didn't anticipate that this would be an issue, but didn't want to leave anything off of the table.  He will likely have that answer tomorrow.

MEDIA ADVISORY M22-123
NASA to Provide Update on Artemis I Moon Mission Status

NASA will hold a media teleconference at 6 p.m. EDT Tuesday, Aug. 30, to discuss the flight test of the agency’s mega Moon rocket and uncrewed Orion spacecraft, currently at Launch Pad 39B at NASA’s Kennedy Space Center in Florida, ahead of the Artemis I lunar mission.

Audio of the teleconference will stream live online at:

https://www.nasa.gov/live

Teleconference participants include:

    Mike Sarafin, Artemis mission manager, NASA Headquarters
    Charlie Blackwell-Thompson, Artemis launch director, NASA Exploration Ground Systems Program, NASA Kennedy
    John Honeycutt, manager, Space Launch System (SLS) Program, NASA’s Marshall Space Flight Center

To participate by telephone, media must RSVP no later than two hours prior to the start of the event to: [email protected]

The Artemis I launch was scrubbed Monday after encountering an issue getting one of the four RS-25 engines on the bottom of the rocket’s core stage to the proper temperature range for liftoff.

Artemis I is a test flight to launch NASA’s Space Launch System rocket and an uncrewed Orion spacecraft around the Moon before the Artemis II mission, which will have astronauts aboard. Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.

The configuration we’ve got is a lot like Shuttle, but with 4 engines instead of 3. Hydrogen loading is same as in Shuttle. Want to take heat out of engines and overboard, sending heat coming out of the engines out through ground system (unlike shuttle)

Engine 3 is the furthest one away from the bleed connection to the ground, however we designed all 4 bleed lines to have the same resistance as each other. Don’t see any difference with engine 3 that’s driving the issue.

Honeycutt: we wanted to get to -420 degrees and didn't get there on any of the four, and engine 3 was most out of line.  Sensors are not flight instrumentation, only for development. We're a little concerned about one of those sensors.

Questioning the fidelity of sensors, they are not flight instrumentation. Similar indicators other than the temperature on all 4 engines. Physics is telling us when we do establish bleed flow on ground we’re seeing cold LH2.

The engine bleed system is different since we had to redesign the engine relief vent after the green run. Changed out to a bigger line. Smaller H2 vent line on ground at Stennis vs. KSC. Have enough data to put story together but still need to put pieces together.

Q-so if it's a bad sensor, won't you get the same readings on Sat? Rationale for launching?
Honeycutt: we'll continue to pour over data and put flight rationale together. We'll have to let the data guide us.

Honeycutt: Target for engine chill is 40 degrees Rankine, or negative 420 degrees Fahrenheit.

SLS engine #3 "was probably about 30 or 40 degrees warmer" than the others.

(Presumably according to the sensor, doesn’t sound like they’re confident what actual engine 3 temp was.)

Mike Sarafin: I misquoted the number of 500 Rankine - John Honeycutt: needs to get engines to 40 Rankine or -420 F. Engine 3 was about 40 deg warmer than the others. 1, 2, 4 around -410 F.

Honeycutt adds that, based on his experience, “it’s not terribly unusual” that a temperature sensor would be off by something like 30-40 degrees. Sensors likely not checked since left the factory.

Honeycutt: "We would have to do a rollback" to the VAB from the launchpad "to get access" into the engine section where the sensor is.

"Replacing the sensor at the launch pad would be tricky. It’s not ideal," Honeycutt said. Sounds like they're going to look at all the other data, such as LH2 flowing into engine no. 3, and have a plan to go with a launch without absolutely knowing the temperature of the engine.

End of the briefing. Takeaway is that NASA is thinking the anomalous engine 3 temp may be a sensor issue: the way the sensor is behaving, Honeycutt said, doesn’t match the physics of the situation. Replacing the sensor now isn’t feasible, so developing flight rationale.

Thank you FST for those great captures from press conference this evening.  I just want to clarify / emphasize two things that might be missed.

[Mike Sarafin said on Monday] Temps should be around 500 Rankin on the engines before they are thermally conditioned.

Mike said today that he'd totally misspoken yesterday.  See posts above for actual numbers which are more like 40 R / -420 F.

Mark Berger: Launch window weather probability of violation circa 60%.  However, the violations might occur, clear, and occur again during the 2 hour window.

I gasped when he said 60% POV, but he immediately followed it with a discussion of how it was actually better than that, due to the long two-hour window and the sporadic nature of the likely showers.

Working in Tandem: NASA’s Networks Empower Artemis I

NASA’s Artemis missions are returning humanity to the Moon and beginning a new era of lunar exploration. Soon, the agency plans to launch the Artemis I mission, an uncrewed flight test that will take a human-rated spacecraft farther than any before.

Although uncrewed, Artemis I will test essential systems for future crewed missions to the lunar region, including the first-ever launch of NASA’s most powerful rocket, the Space Launch System (SLS). The SLS rocket will launch from NASA’s Kennedy Space Center in Cape Canaveral, Florida, and enter a complex orbit to bring the Orion spacecraft to the Moon.

Throughout its journey, the Artemis I mission, including Orion and SLS, will receive comprehensive communications and navigation services from NASA’s two networks: the Near Space Network and the Deep Space Network.

These services are essential during launch, orbit, and re-entry – all phases of the mission. The video above details each network’s support and the collaboration needed between the two to get essential spacecraft and science data from the mission.

This first test of Artemis I will help NASA to prepare the networks for future crewed voyages to the lunar region, and later, on to Mars.

Read more about the networks and their support of Artemis I here.

The Near Space Network, managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the Deep Space Network, managed by NASA’s Jet Propulsion Laboratory in Southern California, receive programmatic oversight from NASA’s Space Communications and Navigation (SCaN) program office within the Space Operations Mission Directorate at NASA Headquarters in Washington.

Tail service mast umbilical: work completed
core stage inter-tank valve: no issue
worked through engine bleed issue
cracks on core stage inter-tank foam: reviewed

only 2 items requiring risk acceptance rationale: thermal insulation and engine bleed

Sept 3rd (Saturday) still on

off-nominal performance scenario for (Sunday?): if there was an under-speed at trans-lunar injection point, there would be an eclipse violation (power issue). Taken off list for launch opportunities.

Marsha Dunn:
Just a Sensor Issue? (John): Yes, we know that it was an issue. Time to review data and compare & independent analysis confirming bad sensor. Lt of things reviewed on engine to see it's how we want it (advanced health monitoring system on each engine: vibrations, ETC as an early warning).

During certain ranges it was as expected, but not at cold temps. High pressure turbo pump bearing (skidding on start-up) is the concern causing premature wear that could cause a shutdown, possibly an un-contained failure.

Bill Harwood: Q: Where in software does the sensor tell the (computer there is an error)?

q: What tells the computers that engine is at correct temperature to start?

A: Sensor not part of start-up. Just an indication of cold fluid.  Not intended for the reason we're looking at it

Trying to chill the engine to get an indication of cold bearing is not based on this sensor.
Mass flow vs time is used in the calculation for bearing temp (there is no specific sensor on the bearing for temp)

Other sensors used to evaluate proper conditions for bearing temps (skin, ETC)

Q (Bloomberg): confirmation that sensor is not part of the critical system?
A1: We do not need this sensor for the system. For chill-down confirmation (cold liquid for a certain amount of time) for engineering analysis.
A2: We had a plan which uses these sensors. Ran into other issues. Off script in terms of normal tanking operation. Managing a hazardous condition - going off script to work though the issues and get into a good configuration. We understand risk posture.
Asked teams if they are ready for tanking? Answer was YES.

Q: Mild concern of shelf life of the stack. # pressure cycles in tank.,
A1: Good config. At least into double digits of available tank cycles. Seeing cracks in TPS. Big thing we want to avoid is rollbacks into VAB (causing vibrations).
A2: We track all the cycles.

Q1: How many cutouts in COLA?
Q2: margins on LH2

A1: They get them at L-2 day: previous opportunity was ~ 30-40 cutouts, some as long as a minute.
A2: Starting bleed earlier will support whole window but a little less left in the tank

Purge can LH2 work: how did they determine it was fixed?

Previous experience on WDR3 allowed them to know what to expect. Looks at all penetrations, soft goods, gaskets, torque values for connections. Some relaxations found & re-torqued.

Similar signature seen in launch attempt 1.
Saw it re-occur during drain.

3, 4, 5-things to check based on that previous experience. 8" connection was found to be loose. Seal replaced & torqued. Torques on flange & gasket nominal. Until you hit it with cryo you don't know.
Q: Why was it loose: unknown. Could have been the roll from the VAB.

Post by: robertross on 09/01/2022 10:57 pm
Q: 1:125 risk on LOV? Has it changed?
A: No appreciable risk increase. Small likely hood foam could come loose at launch and hit at a location on booster where it could become a problem, but probability very low.

Q: Vent valve
A: vent valve in system (intertank) where the leak was. Umbilical that vents out to ground
A2: Hydrogen vent valve system. Flight & ground side plate. Leak picked up was in this particular cavity. Have seen with QDs before that when environment changes (temps) leaks are seen. Procedure to change things now to see if there is a repeat. In this case, QD warmed up and when they opened it (exposed to change in pressure & temperature) we saw the leak. Leak sealed itself during normal chilldown.

Q: Will you simply ignore the sensor on launch day?
A: Yes

Q: will you ignore all 4 sensors?
A: We will see. Not ignoring them. We have witnesses to verify other items no matter what those sensors do

Q: What is the margin for hydrogen. What is the temperature?

A: looking for saturation temperature at the sensor. -420F. There is 40F margin that could be at bearing. Process to ensure the bearing is at the correct temperature.

Nice summary!

Some minor points they mentioned:
- There are 5 measurement points per engine to check bleed
- The faulty sensor is not part of flight hardware and therefore not part of that 5 measurement points
- They have then in the core stage further measurement points to verify bleed [no mention of number of sensors or type]
- Why was the faulty sensor added if it is not necessary for startup? Plan was to verify the bleed based on process parameters (in wdr already). If we would have verified correct bleed, we would have ignored the sensor for the launch attempt. We know, that these sensors are not the best (mentioned in earlier presser: it's a instrumentation sensor, not a flight level sensor)
- 2 digit number of tanking cycles remain
- are you pressing forward to launch now? We are trying to prevent a rollback, as this is stressing the rocket more than anything else
- There are 489 launch commit criterias
- Faulty sensors had the expected ramps which were expected from physics at some times. It was never off scale.

For Saturday’s attempt, there are 45 cutouts in the #Artemis1 2-hr launch window. About 10 of them are a minute in duration; the rest are “a couple of seconds” long.

Thank you to Charlie Blackwell-Thompson and @NASAKennedy PAO for the info.

📸 @thejackbeyer

Edit to add: just to be clear, cutouts are times when they can’t launch (eg due to orbital debris) so can launch during great majority of the window

This suggests no launch attempt Monday or Tuesday, or again until October. Not surprising.

Hearing a rollback to the VAB of the SLS rocket is likely, but I don't have confirmation. If that happens, it is very likely that Artemis I does not launch before October 17, at the earliest.

Artemis I Launch Attempt Scrubbed

The launch director waived off today’s Artemis I launch attempt at approximately 11:17 a.m. EDT. Teams encountered a liquid hydrogen leak while loading the propellant into the core stage of the Space Launch System rocket.  Multiple troubleshooting efforts to address the area of the leak by reseating a seal in the quick disconnect where liquid hydrogen is fed into the rocket did not fix the issue. Engineers are continuing to gather additional data.

MEDIA ADVISORY M22-127
NASA to Provide Artemis I Launch Update Saturday
 
Following the Artemis I launch scrub Saturday from Launch Complex 39B at NASA’s Kennedy Space Center in Florida, the agency will hold a media briefing no earlier than 4 p.m. EDT on Saturday Sept. 3, to discuss mission status. NASA Administrator Bill Nelson provided initial remarks following the scrub.

Artemis I is a flight test to launch NASA’s Space Launch System rocket and an uncrewed Orion spacecraft around the Moon before the Artemis II mission with astronauts aboard.

The briefing will livestream on NASA Television, Twitter and YouTube, as well as the agency’s app. Watch on the agency’s website at:

https://www.nasa.gov/live

Charlie Blackwell-Thompson, NASA’s Artemis launch director, waived off the Artemis I launch attempt at approximately 11:17 a.m. Teams encountered a liquid hydrogen leak while loading the propellant into the rocket’s core stage. Multiple troubleshooting efforts to address the area of the leak by reseating a seal in the quick disconnect where liquid hydrogen is fed into the rocket did not fix the issue. Engineers are continuing to gather additional data.

The following individuals are confirmed to participate in the news briefing at this time, with additional participants to be determined:
•   NASA Administrator Bill Nelson
•   Jim Free, associate administrator for Exploration Systems Development Mission Directorate, NASA Headquarters
•   Mike Sarafin, Artemis mission manager, NASA Headquarters

To participate by telephone, media must RSVP by the start of the call to: [email protected] 
Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars.

Pending post-MMT presser for official words, but the word going around the SLS circles cites evaluations of an October 17 target. So that'd be a rollback to the VAB.

Curious if they'll work in a full WDR when back at 39B or just go for launch.

"Several weeks" needed to roll SLS back out to the pad after work.

Shocked they're even saying the late-September window is in play. With Crew-5 and "several weeks of work" this can't, from a timeline, align to the end of Sept window.  This is most certainly mid-Oct. #Artemis1

Ok, they're hedging on "we'd need to talk to the Range [about not going back to VAB and redoing Flight Termination System batteries]."  So maybe that's how late-Sept. isn't ruled out.  But this is not exactly the "hedge" you want to hear.  These limits are there for a reason.

Free: if FTS is extended and leak can be repaired on the pad, still have to look at issues abut Orion life on the pad to see if can stay there vs rollback.

Yikes! Sarafin said they saw "2 to 3 times" the limit concentration of 4% (G)H2 in the purge canister.

Launch Equipment Test Facility experience hints R&R of the seal is a likely approach. LETF services include: "Qualification testing of umbilical systems in both pre-launch and launch environments."

A long thread here that answers your questions about the cubesats tagging along on the Artemis I mission. TL;DR the SLS delays are a risk but seem to be manageable for most of these little guys.

twitter.com/hardgrove/status/1566408247350894592

Quote
Couldn’t help but notice that there were several questions about the cubesat batteries yesterday at the Sept 3rd NASA SLS press conference. Thanks for thinking of us little guys! Given the interest, here’s a bit more info about that… 1 / 24

The cubesats were delivered to NASA KSC in July of 2021. Each uses the same type of batteries (Li-ion 18650). Each cubesat has a different number of them and were charged to different levels depending upon mission requirements & individual design specifications/decisions. 2 / 24

Each mission requires a different amount of charge on the batteries in order to boot the spacecraft and begin operations. 3 / 24

Each mission measured the rate of “self-discharge” on their batteries at some point prior to delivery and most were consistent with rates around (or less than) 2% per month. 4 / 24

There are several unknowns, however, provided that some missions charged to 100% and the cubesats have been stored in the OSA under ambient conditions without temperature control. Both of these incur an unknown penalty on the monthly rate of self-discharge. 5 / 24

If the rate of self discharge stayed around 2% then, at least for @lunahmap, the batteries would not drop below the minimum required to boot the flight computer and deploy the solar arrays until about 30 months after delivery. 6 / 24

If, however, the self discharge rate went up to 5% per month then @lunahmap would drop below the minimum required to boot in about 12 months after delivery. 7 / 24

Without access to the spacecraft, each cubesat program is doing their best to assess the risks to their mission based on the possible charge states after over 1 year in storage. Many assumptions are required and each mission is assessing the risks given their requirements. 8 / 24

To be clear, the SLS program is doing everything they can to provide charge to those cubesats that are able to charge their batteries. For those that can not, the only way for them to be charged would be to remove the cubesats from the OSA, which requires destacking Orion. 9 / 24

Five of the cubesats on Artemis-1 are unable to charge their batteries. The reasons why vary across the missions. Some did not design that capability, some decided not to, and others were not allowed to due to SLS safety concerns. @lunahmap is one of those that can not. 10 / 24

Upon deployment, all the cubesats use solar panels to charge their batteries and/or power their subsystems. In the case of @lunahmap and CuSP, they were designed so that if sunlight hits their solar arrays the batteries will charge even if the spacecraft has not booted up 11 / 24

If these cubesats deploy below the minimum state of charge, then any exposed solar panels will charge the batteries. Each mission is planning their post-deployment operations differently based on their expected state of charge and their overall mission design. 12 / 24

The CuSP mission, for example, is planning a long wait before their first DSN contact to ensure they are sufficiently charged. 13 / 24

@lunahmap needs to execute a set of propulsive maneuvers shortly after deployment, so a DSN contact is planned early on. With only one of LunaH-Map’s eight solar panels getting sunlight, if power is low it may take a few hours to reach the required charge to boot. Or not. 13 / 24

How long it will take to charge sufficiently will depend upon the current battery stage of charge, which is not known with much certainty. We might be fine or need to wait. The time it takes to charge & get into a safe configuration will be a risk for each mission but …14 / 24

SLS launch delays do NOT mean that the cubesat missions are dead, as long as they were designed to charge after deployment when their solar arrays are exposed to the Sun. For these missions, like @lunahmap and CuSP (possibly others), it just adds some risk. 15 / 24

For LunaH-Map, if launch is after December of 2023 we can be pretty sure we will need to spend a few hours (up to a full day) charging after deployment. But the uncertainty about our rate of self discharge means we could reach that point as soon as fall/winter 2022. 16 / 24

For LunaH-Map, deploying below our minimum charge to boot would be a very big risk to our overall mission success because of how little time we have to commission spacecraft subsystems & execute a lunar gravity assist with our propulsion system post-deployment (~3 days) 17 / 24

So while there is increased risk to the cubesats who can not charge, at worst they will deploy into a “dormant” state and spring to life after some Sun hits their solar arrays. The biggest risk to the missions then is lost time. 18 / 24

I can’t speak to the details for each individual mission, and if you are curious about them I encourage you to reach out to find out the details about how they plan to negotiate a low power state upon deployment. We’re all happy to chat about our exiting missions! 19 / 24

… And while you are here, if you’ll allow me a bit of editorializing. The interaction of some of the smallest interplanetary spacecraft ever built with one of the largest rocket programs ever has been very interesting and ground-breaking. 20 / 24

Accommodating tiny high-risk, high-reward spacecraft on big missions will enhance big mission science. Little spacecraft can collect hard-to-reach but exciting datasets. How big missions accommodate tiny ones is a problem worth solving and it doesn’t have easy solutions. 21 / 24

Tiny spacecraft are designed to different sets of requirements than bigger ones (and rockets). SLS has done a great job of working with all of the different cubesat teams and we are still in a position where we can achieve mission success. 22 / 24

Of course there’s always more to learn, but considering we are all doing this for the very first time ever I think we have set out on a good path forward demonstrating we can work together. Let’s go… To the Moon! And beyond! 23 / 24

Tweets and views are my own and do not represent NASA or the SLS Program 24 / 24

Teams Continue to Review Options for Next Attempt, Prepare to Replace Seal

After standing down on the Artemis I launch attempt Saturday, Sept. 3 due to a hydrogen leak, teams have decided to replace the seal on an interface, called the quick disconnect, between the liquid hydrogen fuel feed line on the mobile launcher and the Space Launch System (SLS) rocket while at the launch pad.

Performing the work at the pad requires technicians to set up an enclosure around the work area to protect the hardware from the weather and other environmental conditions, but enables engineers to test the repair under cryogenic, or supercold, conditions. Performing the work at the pad also allows teams to gather as much data as possible to understand the cause of the issue. Teams may return the rocket to the Vehicle Assembly Building (VAB) to perform additional work that does not require use of the cryogenic facilities available only at the pad.

To meet the current requirement by the Eastern Range for the certification on the flight termination system, NASA would need to roll the rocket and spacecraft back to the VAB before the next launch attempt to reset the system’s batteries.

Additionally, teams will also check plate coverings on other umbilical interfaces to ensure there are no leaks present at those locations. With seven main umbilical lines, each line may have multiple connection points.

Space Launch Delta 45, operator of the Eastern Range, is in discussions with NASA to review its request for an extension of the certification of the Space Launch System rocket's Flight Termination System. The launch criteria for each vehicle are used to develop mission rules that govern the allowable flight behavior to ensure public safety, which is the foremost job of the Eastern Range.

SLD 45 and the Eastern Range have enjoyed a trusted partnership with NASA that dates back to the earliest days of human spaceflight. SLD 45 will continue to provide NASA the launch infrastructure and range resources required to assure safe access to space.

Repair Work Underway, Preparations Continue for Next Launch Opportunity

Engineers are making progress repairing the area where a liquid hydrogen leak was detected during the Artemis I launch attempt Sept. 3, and NASA is preserving options for the next launch opportunity as early as Friday, Sept. 23.

Technicians constructed a tent-like enclosure around the work area to protect the hardware and teams from weather and other environmental conditions at Launch Pad 39B. They have disconnected the ground- and rocket-side plates on the interface, called a quick disconnect, for the liquid hydrogen fuel feed line, performed initial inspections, and began replacing two seals – one surrounding the 8-inch line used to fill and drain liquid hydrogen from the core stage, and another surrounding the 4-inch bleed line used to redirect some of the propellant during tanking operations. The SLS rocket and Orion spacecraft are in good condition while remaining at the launch pad.

Once the work is complete, engineers will reconnect the plates and perform initial tests to evaluate the new seals. Teams will check the new seals under cryogenic, or supercold, conditions no earlier than Sept. 17 in which the rocket’s core stage and interim cryogenic propulsion stage will be loaded with liquid oxygen and liquid hydrogen to validate the repair under the conditions it would experience on launch day. Engineers are in the process of developing a full plan for the checkouts.

NASA has submitted a request to the Eastern Range for an extension of the current testing requirement for the flight termination system. NASA is respecting the range’s processes for review of the request, and the agency continues to provide detailed information to support a range decision. 

In the meantime, NASA is instructing the Artemis team to move forward with all preparations required for testing, followed by launch, including preparations to ensure adequate supplies of propellants and gases used in tanking operations, as well as flight operations planning for the mission. NASA has requested the following launch opportunities:

Sept 23: Two-hour launch window opens at 6:47 a.m. EDT; landing on Oct. 18
Sept. 27: 70-minute launch window opens at 11:37 a.m.; landing on Nov. 5

NASA’s teams internally are preparing to support additional dates in the event flexibility is required. The agency will evaluate and adjust launch opportunities and alternate dates based on progress at the pad and to align with other planned activities, including DART’s planned impact with an asteroid, the west coast launch of a government payload, and the launch of Crew-5 to the International Space Station.

Listen to a replay of today’s media teleconference on the status of the Artemis I mission. Artemis I is an uncrewed flight test to provide a foundation for human exploration in deep space and demonstrate our commitment and capability to extend human existence to the Moon and beyond.

Teams Replace Seals on Artemis I Moon Rocket, Prepare for Tanking Test

After disconnecting the ground and rocket-side plates on the interface, called a quick disconnect, for the liquid hydrogen fuel feed line, teams have replaced the seals on the Space Launch System rocket’s core stage associated with the liquid hydrogen leak detected during the Artemis I launch attempt Sept. 3.

Both the 8-inch line used to fill and drain liquid hydrogen from the core stage and the 4-inch bleed line used to redirect some of the propellant during tanking operations were removed and replaced this week. 

Coming up, technicians will reconnect the umbilical plates and perform inspections over the weekend before preparing for a tanking demonstration as soon as Saturday, Sept. 17. This demonstration will allow engineers to check the new seals under cryogenic, or supercold, conditions as expected on launch day and before proceeding to the next launch attempt. 

During the operation, teams will practice loading liquid hydrogen and liquid oxygen in the rocket’s core stage and interim cryogenic propulsion stage and getting to a stable replenish state for both propellants. Teams will confirm the leak has been repaired and also perform the kick-start bleed test and a pre-pressurization test, which will validate the ground and flight hardware and software systems can perform the necessary functions required to thermally condition the engines for flight.  Following the test, teams will evaluate the data along with plans for the next launch opportunity.

Artemis I Cryogenic Demonstration Test on Track for Wednesday

NASA remains on track for an Artemis I cryogenic demonstration test on Wednesday, Sept. 21. In the days since the previous launch attempt, teams have analyzed the seals that were replaced on an interface for the liquid hydrogen fuel line between the Space Launch System (SLS) rocket and the mobile launcher and adjusted procedures for loading cryogenic, or supercold, propellants into the rocket. Engineers identified a small indentation found on the eight-inch-diameter liquid hydrogen seal that may have been a contributing factor to the leak on the previous launch attempt. 

With new seals, updated cryogenic procedures, and additional ground software automation, teams are now preparing to demonstrate the updates under the same cryogenic conditions the rocket will experience on launch day. During the demonstration, the four main objectives include assessing the repair to address the hydrogen leak, loading propellants into the rocket’s tanks using the new procedures, conducting the kick-start bleed, and performing a pre-pressurization test. 

Based on recent engineering assessments, the new cryogenic loading procedures and ground automation will transition temperatures and pressures more slowly during tanking to reduce the likelihood of leaks that could be caused by rapid changes in temperature or pressure. After the liquid hydrogen tank transitions from the slow fill phase to fast fill, teams will initiate, or “kick-start,” the flow of liquid hydrogen through the engines to begin conditioning, or chilling them down, for launch. After both tanks have reached the replenish phase, the pre-pressurization test will bring the liquid hydrogen tank up to the pressure level it will experience just before launch while engineers calibrate the settings for conditioning the engines at a higher flow rate, as will be done during the terminal count. Performing the pressurization test during the demonstration will enable teams to dial-in the necessary settings and validate timelines before launch day, reducing schedule risk during the launch countdown.

Call to stations for the demonstration occurred at 5 p.m. EDT Monday. The launch director is expected to give a “go” to begin loading cryogenic propellants into the rocket at approximately 7 a.m. Wednesday. The test is planned to conclude around 3 p.m. after the teams have met the objectives and will not go into the terminal count phase of the launch countdown. Teams may extend the duration of the test should circumstances warrant it. 

During the test, teams will load propellants into both the core stage and upper stage tanks, and Orion and the SLS boosters will remain unpowered. Meteorologists currently predict favorable weather for the test with a 15% chance of lightning within 5 nautical miles of the area, which meets criteria required for the test, and will continue to monitor expected conditions.

NASA Television will provide live coverage with commentary of the demonstration beginning at 7:15 a.m. Sept. 21. Continuous live video of the Artemis I rocket and spacecraft at Launch Pad 39B remains available on the Kennedy Newsroom YouTube Channel.

Weather currently 'go'. Approx. 30 mins has been added to the countdown to adjust loading operations from the previous launch attempts (team is planning to load slower and at lower pressure today). Poll for 'go' of cryo is taking place right now as the pad is cleared.

Derrol Nail has just announced on the NASA stream that they are going to try a slightly different plan from the previous leak issue earlier in the month. They are dropping the H2 storage tank pressure to less than 5% PSI and then will very slowly increase the pressure for the fill.

Worth noting that today's leak stopped immediately they stopped the flow earlier.

Currently less than 0.5% H2 leak concentration, but just reaching point where the leak increased earlier today. Monitoring very closely - looking to collect more data.

Have reached 14% LH2 tank full, so tank is filling.

Have now pre-approved plan that if they reach upto 10% leak concentration then they will let that persist for 5 mins to collect data on the seal. Anything above 10% and they will immediately stop flow.

The engine bleed quick disconnect LH2 leak reached 5% during max pressure, but the rate lowered on its own as flow continued. However, anything above 4% would trigger a launch abort if this was launch day. Something for them to evaluate ahead of the next attempt.

NASA Blog update posted at 4:59 PM  on September 21st, after the Cryo test.  (https://blogs.nasa.gov/artemis/2022/09/21/artemis-cryogenic-demonstration-test-concludes-all-objectives-met/)

Artemis Cryogenic Demonstration Test Concludes, All Objectives Met

The launch director has confirmed all objectives have been met for the cryogenic demonstration test, and teams are now proceeding with critical safing activities and preparations for draining the rocket’s tanks. After encountering a hydrogen leak early in the loading process, engineers were able to troubleshoot the issue and proceed with the planned activities. 

The four main objectives for the demonstration included assessing the repair to address the hydrogen leak identified on the previous launch attempt, loading propellants into the rocket’s tanks using new procedures, conducting the kick-start bleed, and performing a pre-pressurization test. The new cryogenic loading procedures and ground automation were designed to transition temperature and pressures slowly during tanking to reduce the likelihood of leaks that could be caused by rapid changes in temperature or pressure. After encountering the leak early in the operation, teams further reduced loading pressures to troubleshoot the issue and proceed with the demonstration test. The pre-pressurization test enabled engineers to calibrate the settings used for conditioning the engines during the terminal count and validate timelines before launch day to reduce schedule risk during the countdown on launch day. 

Teams will evaluate the data from the test, along with weather and other factors, before confirming readiness to proceed into the next launch opportunity. The rocket remains in a safe configuration as teams assess next steps.

MEDIA ADVISORY M22-136
NASA to Provide Media Update on Demonstration Test, Artemis I Mission

NASA will hold a media teleconference at 12:30 p.m. EDT Friday, Sept. 23, to discuss the cryogenic demonstration test conducted Wednesday, Sept. 21, ahead of the next Artemis I launch attempt.

Audio of the call will livestream on the agency’s website at:

https://www.nasa.gov/live

After encountering a hydrogen leak early in the loading process during the test Wednesday, Sept. 21, engineers were able to troubleshoot the issue and complete the test objectives.

Based on data from the test, teams are fine-tuning procedures for the next launch opportunity, targeted for no earlier than Sept. 27.  The rocket remains in a safe and flight-ready configuration at the launch pad.

Artemis I is a flight test to launch NASA’s Space Launch System rocket and send an uncrewed Orion spacecraft around the Moon before future missions with crew.

Briefing participants include:

    Tom Whitmeyer, deputy associate administrator, Common Exploration Systems Development, NASA Headquarters
    Brad McCain, vice president and general manager, Jacobs Space Operations Group
    John Blevins, SLS chief engineer, NASA’s Marshall Space Flight Center

To participate by telephone, media must RSVP two hours before the briefing to: [email protected] 

The four main objectives met during the demonstration were assessing the repair to address the hydrogen leak identified on the previous launch attempt, loading propellants into the rocket’s tanks using new procedures to transition changes in temperature and pressure more slowly to reduce the likelihood of leaks, conducting the kick-start bleed, and performing a pre-pressurization test.

Managers waved off two previous launch attempts, one on Aug. 29 due to a faulty temperature sensor, and one on Sept. 3 due to a liquid hydrogen leak at an interface between the rocket and mobile launcher.

Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence, and serving as a steppingstone to send astronauts to Mars.

Q-are those peak or sustained wind limits?
Blevins: it's 74 *peak* wind gusts at pad, but less than 40 knot *sustained* winds for roll back.

Clarification on wind limits:

SLS is designed to withstand 74.1 knot (85 mph) wind GUSTS at the launch pad.

Rollback is designed to withstand 40 knot (46 mph) SUSTAINED winds while the vehicle is in motion.

There's a big difference between gusts (a few seconds) and sustained.

Upshot: they think tanking test was great even tho the 8"QD leak was diff from last time and don't know why. Keeping 27th for next attempt but will make final wx decision this pm or tmrw. Convinced Range battery is OK for MUCH longer than 20 days but won't say how they did that.

A cancel-and-replace NGA Rocket Launching notice.  (I haven't yet received a matching cancel-and-replace Space Debris notice.)

While the notice being canceled (NAVAREA IV 971/22) is clearly the Artemis I notice, the dates/times in this replacement notice are NOT correct for Artemis I.  It looks like a mid-inclination Starlink launch (or something similar).

It looks like someone screwed up something, but nevertheless NAVAREA IV 971/22 is canceled.

Teams Monitoring Weather While Protecting Option for Artemis I Launch 

NASA is monitoring the forecast associated with the formation of a tropical depression in the Caribbean Sea while in parallel continuing to prepare for a potential launch opportunity on Tuesday, Sept. 27 during a 70-minute window that opens at 11:37 a.m. EDT. 

Managers are initiating activities on a non-interference basis to enable an accelerated timeline for rolling back to the Vehicle Assembly Building (VAB) to protect the rocket, should it be necessary. Discussions about whether to remain at the launch pad or roll back to the VAB are on-going and based on the latest forecast predictions. NASA will make a decision on whether to remain at the launch pad or roll back using incremental protocols to take interim steps necessary to protect people and hardware with a final decision anticipated no later than Saturday. The step-wise decision making process over the next day lets the agency protect its employees by completing a safe roll in time for them to address the needs of their families, while allowing flexibility to hold the launch window should weather predictions improve. 

NASA is grateful to its agency partners at NOAA, United State Space Force and the National Hurricane Center for giving us the highest quality products to protect our nation’s flight test to return us to the Moon.

It looks like someone screwed up something, but nevertheless NAVAREA IV 971/22 is canceled.

Later two cancel-and-replace Space Debris notices came out that appear to be associated with the new Rocket Launching notice.  They are apparently for Starlink 4-35.  See my post here in that topic for further: https://forum.nasaspaceflight.com/index.php?topic=56979.msg2411874#msg2411874 (https://forum.nasaspaceflight.com/index.php?topic=56979.msg2411874#msg2411874).

So it looks like the Rocket Launching notice should have canceled NAVAREA IV 956/22 instead of NAVAREA IV 971/22, but as I said above, nevertheless NAVAREA IV 971/22 is canceled.

Artemis I Managers Wave Off Sept. 27 Launch, Preparing for Rollback

NASA is foregoing a launch opportunity Tuesday, Sept. 27, and preparing for rollback, while continuing to watch the weather forecast associated with Tropical Storm Ian. During a meeting Saturday morning, teams decided to stand down on preparing for the Tuesday launch date to allow them to configure systems for rolling back the Space Launch System rocket and Orion spacecraft to the Vehicle Assembly Building. Engineers deferred a final decision about the roll to Sunday, Sept. 25, to allow for additional data gathering and analysis. If Artemis I managers elect to roll back, it would begin late Sunday night or early Monday morning.

The agency is taking a step-wise approach to its decision making process to allow the agency to protect its employees by completing a safe roll in time for them to address the needs of their families while also protecting for the option to press ahead with another launch opportunity in the current window if weather predictions improve. NASA continues to rely on the most up to date information provided by the National Oceanic and Atmospheric Administration, U.S. Space Force, and the National Hurricane Center.

Thanks to our partners at @NOAA, @SpaceForceDoD, & @NHC_Atlantic and their high-quality forecasting, we're standing down from our Sept 27 #Artemis launch attempt. To protect our employees and the integrated stack, we will begin configuring the vehicle to roll back. (1/2)

Quote
A final decision on rolling back to the Vehicle Assembly Building will be made tomorrow, but this step-wise approach gives our employees time to address the needs of their families while preserving a launch opportunity if conditions improve. https://go.nasa.gov/3DNILfN (2/2)

The 11am ET Tropical Storm Ian forecast from @NHC_Atlantic slips west a bit, as expected. NASA is hoping it goes further, moving KSC out of the cone of uncertainty over the next 24 hours. It's possible, but very, very far from certain.

NASA Closely Monitoring Weather While Rollback Preparations Continue

NASA continues to closely monitor the weather forecast associated with Tropical Storm Ian as preparations for rolling back the Space Launch System rocket and Orion spacecraft to the Vehicle Assembly Building continue. The agency is making incremental decisions that prioritize the agency’s people and hardware and its process is in accordance with established NASA policies for tropical storms and hurricanes.

The latest information provided by the National Oceanic and Atmospheric Administration, the U.S. Space Force, and the National Hurricane Center indicates a slower moving and potentially more westerly track of the storm than yesterday’s predictions showed, providing more time for the agency’s decision making process and for employees to prioritize their families should the storm impact the Kennedy Space Center area.

NASA managers will meet this evening to evaluate whether to roll back or remain at the launch pad to preserve an opportunity for a launch attempt on Oct. 2. The exact time of a potential rollback will depend on future weather predictions throughout the day and could occur Monday or very early Tuesday morning.

Sounds like a small electrical fire. People are back working in the building.

Free doesn't say it, but it sounds like October is definitely out for an Artemis I launch attempt: "I don’t want to say it’s off the table, but I also recognize it’s September 27th. Getting back out there might be a challenge."

Jim Free talked about trades, which I took to mean looking at how long potential work items may take versus which launch windows could be hit.

Q-how much time do you expect to have on the FTS battery now that Range gave you waiver?
Free-they gave us 25 days and then let us extend. Will check, but I think we're still assuming it's 25 days.

Teams Confirm No Damage to Flight Hardware, Focus on November for Launch

Teams at NASA’s Kennedy Space Center in Florida conducted initial inspections Friday to assess potential impacts from Hurricane Ian. There was no damage to Artemis flight hardware, and facilities are in good shape with only minor water intrusion identified in a few locations. Next, engineers will extend access platforms around the Space Launch System rocket and Orion spacecraft inside the Vehicle Assembly Building (VAB) to prepare for additional inspections and start preparation for the next launch attempt, including retesting the flight termination system.

As teams complete post-storm recovery operations, NASA has determined it will focus Artemis I launch planning efforts on the launch period that opens Nov. 12 and closes Nov. 27. Over the coming days, managers will assess the scope of work to perform while in the VAB and identify a specific date for the next launch attempt. Focusing efforts on the November launch period allows time for employees at Kennedy to address the needs of their families and homes after the storm and for teams to identify additional checkouts needed before returning to the pad for launch.

Inspections Underway for Rocket, Spacecraft Before Setting Launch Date

Engineers at NASA’s Kennedy Space Center in Florida are in the process of preparing the Space Launch System (SLS) rocket and Orion spacecraft for the next launch attempt in November for the Artemis I mission. Check-outs conducted this week will allow NASA to finalize the work schedule before rolling SLS and Orion back to Launch Pad 39B.

Since resuming work after Hurricane Ian, teams have extended work platforms around SLS and Orion to assess the exterior and access internal components. Exterior inspections will note any foam or cork from the thermal protection system on the rocket or spacecraft that might need to be repaired. Teams will replace the flight batteries for the interim cryogenic propulsion stage and the boosters, as well as the batteries for the flight termination system in the boosters and core stage.

Work will also include charging the CubeSats that are equipped to be re-charged and have elected to do so. Inside Orion, work will include replenishing the specimens and batteries for the biology investigations riding within the capsule, as well as recharging the batteries associated with the crew seat accelerometers and space radiation experiments.

While teams inside the Vehicle Assemble Building complete check-outs, managers are coordinating with the U.S. Space Force to reserve launch dates on the Eastern Range and working with other parts of the agency to evaluate any potential constraints before NASA sets a target date for the next launch attempt.

Although the Kennedy area received minimal impacts from Hurricane Ian, many team members who live farther west experienced larger effects from the storm and are still recovering. Managers are working with teams to ensure they have the time and support needed to address the needs of their families and homes.

Sorry, I see the previous post answering this.  Thanks.
Comment #725 is all I've seen.  Some of the cubesats are not equipped  to be recharged in place.  Some are.  Some do not have replaceable batteries and would have to be removed and disassembled (probably wherever they were originally built) to have the batteries charged or replaced.  Some are probably fine as is and some might not care; after they are ejected, the sun will recharge the batteries.  It depends on the design of the cubesat and the priorities of the builders.  They will recharge the sats that are accessible, if it is worth the trouble.

I assume at launch time, they will publish a list of the cubesats including which ones they expect to work and which they expect to fail.

It would be MUCH cheaper to build replicas of the cubesats they expect to fail and launch them on an Electron than the costs of delaying to replace their batteries.  (Some of them, may be all of them require destacking Orion and maybe the 2nd stage, which would cost months of schedule and $100s of millions.)

Lesson: don't depend on the world's most expensive cubesat launcher...

NASA Sets Date for Next Launch Attempt for Artemis I Moon Mission

NASA is targeting the next launch attempt of the Artemis I mission for Monday, Nov. 14 with liftoff of the Space Launch System (SLS) rocket carrying the Orion spacecraft planned during a 69-minute launch window that opens at 12:07 a.m. EST. Artemis I is an uncrewed flight test to launch SLS and send Orion around the Moon and back to Earth to thoroughly test its system before flights with astronauts.

Inspections and analyses over the previous week have confirmed minimal work is required to prepare the rocket and spacecraft to roll out to Launch Pad 39B at Kennedy Space Center in Florida following the roll-back due to Hurricane Ian.  Teams will perform standard maintenance to repair minor damage to the foam and cork on the thermal protection system and recharge or replace batteries on the rocket, several secondary payloads, and the flight termination system. The agency plans to roll the rocket back to the launch pad as early as Friday, Nov. 4.

NASA has requested back-up launch opportunities for Wednesday, Nov. 16, at 1:04 a.m. and Saturday, Nov. 19, at 1:45 a.m., which are both two-hour launch windows. A launch on Nov. 14 would result in a mission duration of about 25-and-a-half days with a splashdown in the Pacific Ocean Friday, Dec. 9.

The Nov. 12-27 launch period for Artemis I may be shorter than it appears. NASA currently targeting Nov. 14. Nov. 20 and 21 not available, and due to Holiday Airspace Release Plan, it's possible the Florida range may close from Nov. 22-27 for air travel. So maybe just Nov. 14-19?

Teams On Track for Artemis I Rollout to Launch Pad

Teams are on track to roll the Space Launch System rocket and Orion spacecraft from the Vehicle Assembly Building (VAB) to Launch Pad 39B no earlier than Friday, Nov. 4 with first motion targeted for 12:01 a.m. EDT.

Minor repairs identified through detailed inspections are mostly completed. Preparations are underway to ready the mobile launcher and VAB for rollout by configuring the mobile launcher arms and umbilicals and continuing to retract the access platforms surrounding SLS and Orion as work is completed.

Testing of the reaction control system on the twin solid rocket booters, as well as the installation of the flight batteries, is complete and those components are ready for flight. Engineers also have replaced the batteries on the interim cryogenic propulsion stage (ICPS), which was powered up for a series of tests to ensure the stage is functioning properly. Teams successfully completed final confidence checks for the ICPS, launch vehicle stage adapter and the core stage forward skirt.

Teams are continuing to work in the intertank area of the core stage and upper section of the boosters to replace batteries. These areas will remain open to support remaining battery and flight termination system activities. Flight termination system testing will start next week on the intertank and booster and once complete, those elements will be ready for launch. Charging of the secondary payloads in the Orion stage adapter is complete.

Teams recharged, replaced and reinstalled several of the radiation instruments and the crew seat accelerometer inside Orion ahead of the crew module closure for roll. Technicians will refresh the specimens for the space biology payload at the launch pad. The crew module and launch abort system hatches are closed for the roll to the pad, and engineers will perform final closeouts at the pad prior to launch.

Teams will plan to move the crawler transporter into position outside of the VAB ahead of rolling into the facility early next week. The agency continues to target a launch date no earlier than Nov. 14 at 12:07 a.m. EDT.

NASA is working with U.S. Space Force and the National Hurricane Center to monitor Subtropical Storm Nicole. NASA's Kennedy Space Center in Florida is currently in a HURCON (Hurricane Condition) IV status, which includes implementing checklists and preparations for the storm as the agency continues to prioritize its employees in the Kennedy area. Based on current forecast data, managers have determined the Space Launch System rocket and Orion will remain at Launch Pad 39B. Teams at Kennedy will continue to monitor the weather, make sure all personnel are safe, and will evaluate the status of the Monday, Nov. 14, launch attempt for the Artemis I mission as we proceed and receive updated predictions about the weather.

NASA Prepares Rocket, Spacecraft Ahead of Tropical Storm Nicole, Re-targets Launch

NASA is continuing to monitor Tropical Storm Nicole and has decided to re-target a launch for the Artemis I mission for Wednesday, Nov. 16, pending safe conditions for employees to return to work, as well as inspections after the storm has passed. Adjusting the target launch date will allow the workforce to tend to the needs of their families and homes, and provide sufficient logistical time to get back into launch status following the storm.

Kennedy currently is in a HURCON (Hurricane Condition) III status, which includes securing facilities, property and equipment at the center, as well as briefing and deploying the “ride-out” team.  As part of NASA’s hurricane preparedness protocol, a “ride-out” team includes a set of personnel who will remain in a safe location at Kennedy throughout the storm to monitor centerwide conditions, including the flight hardware for the Artemis I mission. Kennedy will release non-essential personnel at the HURCON II status as the agency continues to prioritize its employees in the Kennedy area.

Based on expected weather conditions and options to roll back ahead of the storm, the agency determined Sunday evening the safest option for the launch hardware was to keep the Space Launch System (SLS) rocket and Orion spacecraft secured at the pad.

The SLS rocket is designed to withstand 85 mph (74.4 knot) winds at the 60-foot level with structural margin. Current forecasts predict the greatest risks at the pad are high winds that are not expected to exceed the SLS design. The rocket is designed to withstand heavy rains at the launch pad and the spacecraft hatches have been secured to prevent water intrusion.

In preparation for the storm, teams have powered down the Orion spacecraft, SLS core stage, interim cryogenic propulsion stage, and boosters. Engineers have also installed a hard cover over the launch abort system window, retracted and secured the crew access arm on the mobile launcher and configured the settings for the environmental control system on the spacecraft and rocket elements. Teams also are securing nearby hardware and performing walkdowns for potential debris in the area.

Teams are poised to resume work as soon as weather and Kennedy center status allows. Once back on-site, technicians will perform walkdowns and inspections at the pad to assess the status of the rocket and spacecraft as soon as practicable.

A launch during a two-hour window that opens at 1:04 a.m. EST on Nov. 16 would result in a splashdown on Friday, Dec. 11. If needed, NASA has a back-up launch opportunity on Saturday, Nov. 19, and will coordinate with the U.S. Space Force for additional launch opportunities.

The agency continues to rely on the most up to date information from the National Oceanic and Atmospheric Administration, U.S. Space Force, and the National Hurricane Center throughout its evaluations and continues to closely monitor conditions for the Kennedy area.

Yikes. Looks like gusts of 85 mph (Artemis I / SLS’ threshold) were just recorded around pad 39B. Still a while to go before Nicole’s done.

Maximum gust of 84 knots recorded, that exceeds the ~80 knot safety limit at tower height of 130 feet.

Artemis MMT messed up.

A wind gust of 88 mph (77 knots) was just measured at the 257 ft level at Launch Complex 39B, where NASA's 322-foot-tall Artemis 1 moon rocket is riding out Hurricane Nicole.

NASA has said the rocket is designed to withstand an 85 mph (74 knot) gust.

In reality I’m sure there’s some margin but I do wonder what sort of inspections / analysis might be needed to clear for launch. Let’s hope this is as high as it gets.

And the wind NASA’s Space Launch System is experiencing at LC-39B climbs even higher: 87 knots / 100mph😬

Gusts have exceeded NASA’s 74.1 knot gust limit for the past hour and sustained winds have climbed within only a few knots of the gust limit, too. Big time yikes🤯

Update on our #Artemis I mission:

Quote
Peak conditions for Nicole have passed at NASA Kennedy, and our focus is now on our employees and then getting back into launch operations. Many people are without power and have experienced high winds and broken tree branches at their homes. Teams monitored SLS and Orion remotely during the storm and successfully maintained purges and other essential support. While wind sensors at the launch pad detected peak wind gusts up to 82 mph (71 knots) at the 60-foot level, this is within the rocket's capability. We anticipate clearing the vehicle for those conditions shortly.

Our team is conducting initial visual check-outs of the rocket, spacecraft, and ground system equipment with the cameras at the launch pad. Camera inspections show very minor damage such as loose caulk and tears in weather coverings.
The team will conduct additional onsite walk down inspections of the vehicle soon.

We took the decision to keep Orion and SLS at the launch pad very seriously, reviewing the data in front of us and making the best decision possible with high uncertainty in predicting the weather four days out. With the unexpected change to the forecast, returning to the Vehicle Assembly Building was deemed to be too risky in high winds, and the team decided the launch pad was the safest place for the rocket to weather the storm.

We are grateful to the Space Force, NOAA, and the National Hurricane Center for their continued and steadfast support with valuable data that helps us make informed decisions and proves that the science we'll conduct on Artemis starts right here on planet Earth.

Free says the SLS stack rated for 11 rolls (one way) between VAB and LC-39B, the first time I recall that number. He says 6 rolls are left. But they’ve done 7 rolls now (2 roundtrips for WDRs, 1 roundtrip for earlier launch attempt and last week); either 4 left or rated for 13.

Teams Conduct Check-outs, Preparations Ahead of Next Artemis I Launch Attempt

NASA continues to target launch of its Artemis I mission from the agency’s Kennedy Space Center in Florida at 1:04 a.m. EST, Wednesday, Nov. 16. There is a two-hour launch window for the agency’s first integrated flight test of its Space Launch System (SLS) rocket and Orion spacecraft.

Teams conducted thorough assessments at Launch Complex 39B beginning Thursday evening, closely inspecting SLS, Orion, mobile launcher, and other pad-related assets to confirm there were no significant impacts from Hurricane Nicole, which made landfall more than 70 miles south of the launch pad. The physical inspections augmented remote monitoring via sensors and high-resolution cameras performed during the storm by a team in a safe location at Kennedy.

Space Launch System engineers have performed detailed analysis to confirm the sustained and peak winds experienced during the storm have no adverse effect on the structural strength of the rocket. While varying peak winds were measured by sensors at different heights at the pad, all measurements remained below 75% of SLS design limits, which also are intentionally conservative. Data from testing with actual hardware during the structural test series and modal testing, as well as other evaluations and modeling, provide confidence there is margin beyond the design ratings.

Technicians also are working to fix several minor items from the storm. Most repairs involve loose caulk or weather coverings. An umbilical used to provide purge air, or proper environmental conditions to the Orion spacecraft, was out of position. The umbilical maintained purge throughout the storm and has been repositioned to allow proper retraction at liftoff. Engineers have also removed the hard cover over the launch abort system window installed before the storm and will inspect the window to confirm it is in good condition for launch.

Today, as part of normal launch preparation, engineers are in the process of powering up rocket and spacecraft elements to confirm all systems are healthy. Powered health checks will continue until Saturday. Engineers plan to conduct the standard final software and hardware-related tests required before launch, on Sunday. The Artemis I mission management team will convene Sunday afternoon to review the preparations for launch.

There are actually launch opportunities on all days from 16 Nov t 25 Nov, except 21 Nov. However once NASA commits to fuelling the rocket, the days suddenly become constrained, which is why only your three dates make sense in most situations.

Our #Artemis I team polled GO to proceed toward a launch attempt of our flight test. Overnight, we'll start the countdown and power up @NASA_SLS, while we work actions. Launch is targeted for Nov 16 at 1:04AM ET. Follow the Artemis blog for the latest: blogs.nasa.gov/artemis

Managers Proceed Toward Nov. 16 Launch, to Meet Monday

The Artemis I mission management team met Sunday evening to review the status of preparations for launch and gave a “go” to proceed toward a Nov. 16 launch attempt. The team will meet again Monday afternoon to review additional analysis associated with caulk on Orion’s launch abort system that came loose during Hurricane Nicole. The two-hour window for launch opens at 1:04 a.m. EST Wednesday. The countdown clock will begin at 1:54 a.m. Monday.

Within the next day, engineers will conduct detailed analysis of several feet of delaminated caulk where the ogive on Orion’s launch abort system meets the crew module adapter. The analysis will assess risk should it come loose during launch.

Overnight, in parallel with launch preparations, technicians also will remove and replace a component of an electrical connector on the hydrogen tail service mast umbilical ground-side plate. Engineers continue to see some inconsistent data provided through the connector, despite replacing the cable to the connector earlier in the week. Engineers have redundant sources for the information provided through the connector and it is not an impediment to launch.

NASA will provide a prelaunch status update Monday afternoon after the mission management team reconvenes.

Live coverage of tanking operations with commentary on NASA TV will begin on Tues., Nov. 15 at 3:30 p.m. EST. Full launch coverage in English will begin at 10:30 p.m. and NASA en espanol broadcast coverage will begin at 12 a.m. Wednesday. Click here for the latest information on launch briefings and events.

It's on the LAS Boost Cover, which will be discarded along with the LAS during ascent. It's not launch-critical and  shouldn't affect the launch.

Got info on why only a scrub is available once #Artemis countdown crosses T-33secs.  After that piont, flight software transitions to flight mode & only way to get flight mode fully backed out & reset is to detank SLS. Hence, scrub.

My understanding is that de-tank the first time is a 2-day process to get back to a launch attempt, and then a second time is 3-day turnaround?

https://twitter.com/chrisg_nsf/status/1592178206848712706

From a commodity perspective, yes.  First scrub is replenish only LH2 for a 48-hour turnaround.  Second scrub would be 72-hour turnaround to replenish LH2 and LOX.  For this week, they'll take the 72-hr plan as a baseline and adjust when needed based on scrub & timing.

Artemis I managers convened Monday afternoon to review the status of countdown operations as well as two open technical items, and gave a “go” to proceed toward launch Wednesday, Nov 16. The two-hour window for launch opens at 1:04 a.m. EST.

Engineers examined detailed analysis of caulk on a seam between an ogive on Orion’s launch abort system and the crew module adapter and potential risks if it were to detach during launch. The mission management team determined there is a low likelihood that if additional material tears off it would pose a critical risk to the flight.

Technicians also completed replacing a component of an electrical connector on the hydrogen tail service mast umbilical. While swapping the component did not fully fix the issue, engineers have redundant sources of information supplied through the connector.

Where to See the Artemis I Mission Liftoff to the Moon

When NASA’s Space Launch System rocket and Orion spacecraft launch on the uncrewed Artemis I flight test to the Moon, it will be visible along the Space Coast and throughout parts of Florida for a brief minute or so. NASA is targeting the next launch attempt of the Artemis I mission for Wednesday, Nov. 16 during a 120-minute launch window that opens at 1:04 a.m. EST. Weather permitting, the bright light from the plumes of the Moon rocket’s twin solid rocket boosters and four RS-25 engines could be seen against the dark night sky for up to 70 seconds after liftoff from NASA’s Kennedy Space Center. The rocket and spacecraft will no longer be visible to the naked eye after reaching an altitude of 42,000 feet. Launch visibility is dependent upon several factors, including launch time and dates. To learn more about the Artemis I mission, follow NASA’s Artemis blog for updates.

12/x. Per RTV, there is a small chance more RTV could come off, but flight rationale supports this risk. In order for it to cause an issue in flight, it would have to liberate and hit a critical area. NASA feels if more liberates, it will tear apart in small pieces.

14/x. Per RTV, NASA says, based on atmospheric pressure decrease with altitude increase, that there is a "small aerodynamic window of concern" for RTV delamination and impact downstream on the vehicle.

Before giving final approval for the next Artemis 1 launch attempt, engineers are assessing hurricane damage to caulk-like material known as RTV on the exterior of the Orion spacecraft -- the thin band visible above the NASA “worm” logo in this file photo.

That is completely incorrect. It is *NOT* on the Orion Spacecraft. It is on the LAS Boost Cover, which will be discarded during ascent. The Orion spacecraft is completely covered by the boost cover and isn't even visible.

Mission Managers Give “Go” to Proceed Toward Tanking Operations for Artemis I

The Artemis I mission management team met today to review the status of operations and has given the “go” to proceed toward tanking operations. Weather conditions are 80% favorable for the two-hour launch window which opens at 1:04 a.m. EST Nov. 16, with the primary concern being the potential for thick clouds.

Launch director Charlie Blackwell-Thompson is expected to give the “go” shortly to officially begin propellant loading operations. During tanking operations, teams will load the Space Launch System (SLS) rocket with liquid oxygen (LOX) and liquid hydrogen (LH2), beginning with the rocket’s core stage and then the interim cryogenic propulsion stage.

Tanking begins with chilling down the LOX and LH2 lines for the core stage.  In sequential fashion, LOX and LH2 will flow into the rocket’s core stage tank and be topped off and replenished as some of the cryogenic propellant boils off. The process involves slowly filling the core stage with propellant to thermally condition the tank until temperature and pressure are stable before beginning fast fill operations, which is when the tank is filled at a quicker pump speed. As the super cold liquid oxygen fills the core stage tank, some venting may be visible.

At 3:30 p.m., NASA TV coverage begins with commentary of tanking operations to load propellant into the SLS rocket. Full coverage begins at 10:30 p.m. in English and at midnight Wednesday, Spanish coverage begins on NASA en español YouTube page.

Derrol Nail, NASA Communications for Artemis Launch Control, says however 3:22 PM Eastern. That might put them 3 minutes behind the nominal timeline.

He also says they are, "Looking to begin chilldown of Main Propulsion System."

Terminal count [GLS start] still at 12:54, launch window still opens at 1:04, both times Eastern.

The launch azimuth of Artemis 1 depends on exactly when in the window it launches. The later into the window launch occurs, the more "southerly" the launch azimuth

If you're signed up to FC, I've made 5 simulations each separated by a quarter-window:

We're doing really well with tanking operations. 1.5 hours of LH2 and 2.5 hours of LO2 fast fill to go. Different loading operation used for this attempt. Did a tanking test with updated procedures. Finding the right sequence. Everything is going extremely well. Right on the timeline.

Investigated and looked at all systems from power up and outside visual inspections. Keeping a close eye on. Made through all of that work yesterday. Have not seen any issues.

Sun has just set.

Engine bleed is complete. Did see a little bit of GH2. Saw 4% which is within range.

GH2 from engine bleed is burned at flare stack at right. Currently in a vented bleed configuration. Will stay in that until terminal count. Impurities give colour to the flame.

An intermittent leak in the Core Stage LH2 Replenish Valve has caused a Stop Flow condition. A plan to send specially trained "Red Team" to the pad is being put in work by the NASA Test Director (NTD). The valve is in the base of the Mobile Launcher itself, not on the LH2 TSMU.

Leak is on a skid on the side of the mobile launcher. LH2 is in stop-flow. Only way to fix it is to send in the red crew. The plan is to send two technicians to compartment AB12 to torque packing nuts. Will send in two vehicles. Up to stairs to zero deck and then downstairs. Will take about 15 minutes and then return to vehicles. Emergency services and pad rescue are standing by.

#Artemis I Update: We are extending the countdown hold at T-10 minutes while the launch team estimates how much work needs to be done. This means we will slip into the two-hour launch window, and will share a revised launch time when it is confirmed.

Possible separation of RTV from Orion ogive panel. RTV has a sensor in it. The RTV could come off. Happened after hurricane. The cork that encompasses this sensor is likely to come off. Falls within the same amount of risk as in a day ago. Constraint has been removed from list. RTV unlikely to hit LVSA.

Currently 9 minutes into window. Team evaluating work they have left to do and the time it would take. Not ready to resume polling at this moment. Rough calculation than no earlier than 1:45 am local (6:45 UTC).

The test for the destruct system hasn't been completed yet.

Update on new issue:  Launch team was studying possible liberation of RTV around Orion.
Problem is caulk has sensor in it and have determined that it is loose and could come off.
Was before MMT a day ago, team has determined that this caulk encompassing the sensor on Orion is likely to come off, is doing full analysis on resulting FOD trajectories.  Constraint has been removed.
Likely to hit LVSA, structure can withstand impact- leading to removal of constraint.

Continuing to slip into launch window pending evaluation of remaining work and time prior to go/no-go polling, not ready to resume at the moment.

Rough calculation is NET 1:45AM Eastern time.

Continuing with the tradition of the tie-cutting, former Space Shuttle launch director, Mike Leinbach, cuts the tie of Kennedy's first female launch director, Charlie Blackwell-Thompson.

Perigee Raise Maneuver Complete

The perigee raise maneuver has been successfully completed. The interim cryogenic propulsion stage fired for just over 20 seconds to raise the lowest point of Orion’s Earth orbit in preparation for the critical trans-lunar injection burn that will send Orion to the Moon. The trans-lunar injection burn is currently targeted for about 3:14 a.m. EST and will last about 18 minutes.

Leaving the KSC Visitor Center, just now stopped hyperventilating.  As Jody Foster said in the movie Contact:  "No words, no words...." to describe the experience.  The launch was absolutely surreal and made even more so by the 3rd Quarter Moon, Mars directly overhead and Orion rising.  Congratulations to the Artemis team for taking the first step in the permanent habitation of the Solar System.

Booster separation. This point in flight was especially cool to see. When the boosters are still spewing bits of propellant like sparks. It reminded me of what it looks like when a spacecraft is reentering Earth’s atmosphere.

Orion on Its Way to the Moon

The interim cryogenic propulsion stage (ICPS) completed its approximately 18-minute trans-lunar injection (TLI) burn and the spacecraft has separated from the stage. Orion fired its auxiliary thrusters to move a safe distance away from the expended stage and the spacecraft is on its way to the Moon.

NASA will hold a postlaunch news conference at 5 a.m. EST today from Kennedy Space Center in Florida. Participants are:

Bill Nelson, NASA administrator
Mike Sarafin, Artemis mission manager, NASA Headquarters
Mike Bolger, Exploration Ground Systems Program manager, Kennedy
John Honeycutt, Space Launch System Program manager, Marshall
Howard Hu, Orion Program manager, NASA’s Johnson Space Center
Emily Nelson, chief flight director, Johnson

- Funnies on STRs.
- Funnies on switches on the SAWs.

But all working and pressing on.

Some debris liberation early in flight, might be RTV but not sure yet.

The STRs were showing "no prime" flags, but they did power them in spite of the flag.

SAW#3 showed two microswitches that showed no latching, although they later did show latching. Probably a thermal issue with the sensor.

Some DFI dropped out during the flight, but obviously not a cause for concern, just some developmental data loss.

Today was monumental for NASA, the United States, and the world. Our first Artemis mission is on its way to the Moon, and for so many globally, a dream was realized today.

The contributions to get us to today can't be measured; they are more than pieces of hardware. The contributions are hard-working people's hearts and souls. Our teams give up time with their families and things that they love to do because they love this dream more.

Today was a culmination for our teams - an opportunity to finally exhale. But it was a beginning for humanity to see what a new generation of explorers is truly capable of when they rally around a goal to explore.

Through Artemis, we'll conduct amazing science and learn how to live on another world, and thanks to Artemis, humans will walk on Mars.

The Artemis generation has arrived, and we are going.

Here's a view of the Orion spacecraft's Orbital Maneuvering System, or OMS, main engine taken during ground testing.
This OMS engine is being reused from the space shuttle program. The engine flew on 19 shuttle missions from 1984 though 2002.

TIME

  Barycentric Dynamical Time ("TDB" or T_eph) output was requested. This
continuous relativistic coordinate time is equivalent to the relativistic
proper time of a clock at rest in a reference frame comoving with the
solar system barycenter but outside the system's gravity well. It is the
independent variable in the solar system relativistic equations of motion.

  TDB runs at a uniform rate of one SI second per second and is independent
of irregularities in Earth's rotation.

  Calendar dates prior to 1582-Oct-15 are in the Julian calendar system.
Later calendar dates are in the Gregorian system.

What's  going on with Omotenashi? The Japanese twitter points to this article:

https://www3.nhk.or.jp/news/html/20221117/k10013894211000.html

They say the lander communication is "unstable", but I don't know what it means. And I'm not sure the Google translate works well in this case.

Currently, there's an uplink to the spacecraft (according to DSN NOW https://eyes.nasa.gov/dsn/dsn.html ), but I don't see a downlink.

Some people claim that they have until tomorrow to restore the mission so it can perform a maneuver which is necessary to hit the Moon.

Post by: Svetoslav on 11/16/2022 06:18 pm
I just glanced at DSN now, that spacecraft is presently showing it is part of an MSPA pass on DSS-25 with LunarIceCube.   
Omotenashi was in setup/teardown/tracking - so not much I could discern from that.

If you happened to see an uplink, did you catch the bit rate for the uplink?
If you check and report or ask questions, grab the textual information from "More detail" at the bottom right of the spacecraft info display.

If there was an uplink at low bit rate and no downlink, they may have been blind commanding a spacecraft that is having trouble.
That's speculation on my part without some actual data to back it up.

NASA’s Artemis I Cameras to Offer New Views of Orion, Earth, Moon

During Artemis I, NASA’s Space Launch System (SLS) rocket will send the agency’s Orion spacecraft on a trek 40,000 miles beyond the Moon before returning to Earth. To capture the journey, the rocket and spacecraft are equipped with cameras that will collect valuable engineering data and share a unique perspective of humanity’s return to the Moon.

There are 24 cameras on the rocket and spacecraft – eight on SLS and 16 on Orion – to document essential mission events including liftoff, ascent, solar array deployment, external rocket inspections, landing and recovery, and capture images of Earth and the Moon.

On the rocket, four cameras around the engine section point up toward Orion, two cameras at the intertank by the top of boosters will capture booster separation, and two cameras on the launch vehicle stage adapter will capture core stage separation. The eight cameras will cycle through a preprogrammed sequence during launch and ascent.

On Orion, an external camera mounted on the crew module adapter will show the SLS rocket’s ascent, providing the “rocket cam” view the public often sees during launches. Another camera will provide a view of service module panel jettison and solar array wing deployment. Four cameras attached to the spacecraft’s solar array wings on the service module will help engineers assess the overall health of the outside of Orion and can capture a selfie view of the spacecraft with the Earth or Moon in the background.

“Each of Orion’s four solar array wings has a commercial off-the-shelf camera mounted at the tip that has been highly modified for use in space, providing a view of the spacecraft exterior,” said David Melendrez, imagery integration lead for the Orion Program at NASA’s Johnson Space Center in Houston.

The arrays can adjust their position relative to the rest of the spacecraft, which will optimize the collection of sunlight converted into electricity to power Orion. This also allows flight controllers in the Mission Control Center at NASA Johnson to point the cameras at different parts of the spacecraft for inspections and to document its surroundings, including the Earth and Moon.

The cameras on NASA's Orion spacecraft.

A specialized camera on the crew module adapter used for optical navigation and to help pinpoint Orion’s location in deep space will be used to collect imagery of the Moon during Orion’s closest approach to the lunar surface. Also affixed to the crew module adapter but pointed inward, another camera is positioned to capture imagery of Orion’s heat shield after the crew module separates from the service module before its re-entry into Earth’s atmosphere.

Inside the spacecraft, three more wireless cameras can capture the perspectives astronauts will have on future Artemis missions, with one camera looking out the front pilot window and a second looking over the shoulder of the commander seat, where the instrument panel will be located on future missions. A third in-cabin camera will look out the top hatch window to provide views of launch abort system jettison during ascent as well as parachute deployment during landing and recovery.

There are also two external high-speed cameras dedicated to monitoring parachute operations, which technicians will download and process after the flight.

The images and video collected by the Orion cameras will come in a variety of formats, ranging from standard-definition to high-definition and up to 4K. Each is tailored for a specific use and dependent on the bandwidth available during the mission to send to Earth or recorded on board to be analyzed after the mission ends. Due to bandwidth limitations on the spacecraft that prioritize transmitting critical data to the ground, livestream video quality will be lower than the onboard recordings. As a result, some of the highest quality views may not be received until well after they are recorded and can be downlinked.

The field of view of each camera has been optimized to look at the spacecraft, not deep space, and imagery for the Artemis I flight will depend on a variety of factors such as lighting, spacecraft orientation, and communication capabilities during different mission phases.

“A lot of folks have an impression of Earthrise based on the classic Apollo 8 shot,” Melendrez said. “Images captured during the mission will be different than what humanity saw during Apollo missions, but capturing milestone events such as Earthrise, Orion’s farthest distance from Earth, and lunar flyby will be a high priority.”

Orion also will carry cameras that are part of a technology demonstration, called Callisto. The Callisto payload includes three in-cabin cameras that will be used to test video conferencing capabilities and may enhance the public’s ability to imagine themselves inside Orion.

Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence, and serving as a steppingstone to send astronauts to Mars.

Mission elapsed time 1 day, 12 hours, 25 minutes.

Orion's current distance from the Earth is now 149,245 miles. Distance to the Moon 159,002 miles.

At this distance, the Earth from the perspective of a hypothetical crew would have an angular diameter of about 3 degrees in the sky. The Moon would have grown slightly, but would still appear relatively similar to that of a view from an observer on Earth at about 37 arcminutes.

My guess, and I emphasize it's a guess, is that that with the SLS gone there are ITAR-sensitive parts of the mobile launch tower exposed. A secondary possibility is there was damage to the structure from the launch. But NASA has be super senstitive about ITAR, so probably that.

Statement from NASA on the state of the launch pad 39B a day after the launch of SLS. No word on damage but they are assessing debris there.

Hi Chris - See below from NASA:

Teams still are in safing operations at the pad, and it remains a controlled area. At this time, only essential personnel are permitted to enter the pad perimeter.
Media is expected to be able to retrieve their cameras tomorrow morning. Because of the current state of the configuration, there are ITAR restrictions and photos are not permitted at this time. There also is launch debris around the pad as anticipated, and the team is currently is assessing.


I asked them to provide vou with more info on the ITAR situation:

The umbilical plates are exposed, and high-res shots of those would be an ITAR violation.

During the Artemis post launch conference (linked above), Administrator Nelson said, at 28-29 minutes of the (You Tube) video, that Artemis II will launch in 2 years and Artemis III in 3 years (from now).

Asked at what time Orion arrives at the Moon, Mike Serafin indicated at 1h2m of the (You Tube) video that "the outward powered flyby is on the 21st at 7:44 am, eastern time.

That is first of the two maneuver sequence that does that lunar flyby in the slingshot of 62 miles from the surface of the Moon. We do that behind the Moon by the way, so we are not going to see it until after the maneuver is complete, so we are kind of blind and, when we get acquisition of signal on the spacecraft afterward, we will know that the maneuver was successful."

And then he added that "the second of the maneuvers for the distance retrograde insertion is on the 25th, so I guess that is the day after thanksgiving, at 4:52 pm".

Mission elapsed time 2 days, 6 hours, 54 minutes.

Orion's current distance from the Earth is now 185,384 miles. Distance to the Moon 133,009 miles.

Newton has put on the brakes and decelerated Orion by about ~440 mph over the last 12 hours.

Artemis I – Flight Day Four: Testing WiFi Signals, Radiator System, GO for Outbound Powered Flyby

On Saturday, Nov. 19, the Mission Management Team polled “go” for Orion’s outbound powered flyby past the Moon. NASA will cover the flyby live on NASA TV, the agency’s website, and the NASA app starting at 7:15 a.m. EST Monday, Nov. 21. The burn is planned for 7:44 a.m. Orion will lose communication with Earth as it passes behind the Moon from 7:25 a.m. through 7:59 a.m., making its closest approach of approximately 80 miles from the surface at 7:57 a.m.

During flight day four, flight controllers moved each solar array to a different position to test the strength of the WiFi signal with the arrays in different configurations. The Integrated Communications Officer, or INCO, tested the WiFi transfer rate between the camera on the tip of the solar array panels and the camera controller. The goal was to determine the best position to most efficiently transfer imagery files. Teams learned that having multiple cameras on at once can impact the WiFi data rate, and therefore, future solar array wing file transfer activities will be accomplished from one solar array wing at a time to optimize transfer time.

The Emergency, Environmental, and Consumables Manager, or EECOM, tested Orion’s radiator system. Two radiator loops on the spacecraft’s European Service Module help expel excess heat generated by different systems throughout the flight. Flight controllers are testing sensors that maintain the coolant flow in the radiator loops, switching between different modes of operation and monitoring performance. During speed mode, the coolant pumps operate at a constant rate. This is the primary mode used during Artemis I. Flow control mode adjusts the pump speed as needed to maintain a constant flow through the system. The flight test objective is to monitor system performance and the accuracy of flow sensors to characterize the stability of this mode of operation.  Each loop is monitored in flow control mode for 72 hours to provide sufficient data for use on future missions.

As part of planned testing throughout the mission, the guidance, navigation, and control officer, also known as GNC, performed the first of several tests of the star trackers that support Orion’s navigation system. Star trackers are a navigation tool that measure the positions of stars to help the spacecraft determine its orientation. In previous flight days, engineers evaluated initial data to understand star tracker readings correlated to thruster firings. 

Engineers hope to characterize the alignment between the star trackers that are part of the guidance, navigation and control system and the Orion inertial measurements units, by exposing different areas of the spacecraft to the Sun and activating the star trackers in different thermal states. 

Just after 5:30 p.m. on Nov. 19, Orion had traveled 222,823 miles from Earth and was 79,011 miles from the Moon, cruising at 812 miles per hour. You can track Orion via the Artemis Real-Time Orbit Website, or AROW.

Overnight, engineers in mission control will uplink large data files to Orion to better understand how much time it takes for the spacecraft to receive sizeable files. On flight day five, Orion will undergo its third planned outbound trajectory correction burn to maneuver the spacecraft and stay on course to the Moon.

Learn more about the console positions in mission control and the additional test objectives planned throughout the mission.

Star trackers are sensitive cameras that take pictures of the star field around Orion. By comparing the pictures to its built-in map of stars, the star tracker can determine which way Orion is oriented. The star trackers on Orion are located on the European Service Module on either side of the optical navigation camera. This Nov. 2019 photo was taken as the Orion crew and service module stack for Artemis I was lifted out of the Final Assembly and Test (FAST) cell.

There are currently two (minor) open issues with Orion:

Quote
One team is currently looking at the star tracker system to understand a number of faults in the random access memory, which have been successfully recovered with power cycles. A second team is analyzing a few instances in which one of eight units located in the service module that provides solar array power to the crew module, called a power conditioning and distribution unit umbilical latching current limiter, opened without a command. The umbilical was successfully commanded closed each time and there was no loss of power flowing to avionics on the spacecraft. Both systems are currently functioning as required, and there are no mission impacts related to these efforts. Analyzing the data for these systems and understanding their behavior during an active flight test while the hardware is in the deep space environment will improve mission operations on Artemis I and future missions

https://blogs.nasa.gov/artemis/2022/11/20/artemis-i-flight-day-five-orion-enters-lunar-sphere-of-influence-ahead-of-lunar-flyby/

Dazzling of the star trackers by the nearby side AOCS thrusters was also mentioned a few days ago as an issue, unsure whether it's been resolved in the meantime.

SLS/Artemis 1: 2 minutes after passing within about 80 miles of the lunar surface at 7:57am (1257 UTC), Orion will swing back into contact as it whips around the moon on a trajectory that will carry the spacecraft back out toward a planned "distant retrograde orbit," or DRO

SLS/Artemis 1: The 2.5-minute burn of the main engine will start at 7:44am (1244 UTC), about 19 minutes after the capsule passes behind the moon and out of contact with Earth; the burn will change Orion's velocity by about 400 mph

Last chances to save OMOTENASHI mission end 2022/11/22 00:00 JST  - 2022/11/21 15:00 GMT:

Quote
Thank you for your supports. Unfortunately, we have yet to receive signals from OMOTENASHI. The orbit was not so different from it separated from the rocket. However, there is a possibility its orbit has some errors, and we did search operations by deviating JAXA's antennas. Although we first planned to operate with the UDSC64M antenna, we exchanged the antenna with the EQUULEUS team as the USC34M antenna has a broader beam. Now we cannot execute pre-established landing sequences. But if we recover our spacecraft in a day, it is possible to fire and deaccelerate the Solid Rocket Motor and let OMOTENASHI land on the Moon in free fall at perilune. The time of passing that point is at about 24:00 on 11/21 JST. Therefore, we prepared command files to establish three axes attitudes control, pre-sequences for landing, and landing sequences. We confirmed these commands worked fine with the simulator of OMOTENASHI yesterday. Tonight is the last chance to land on the Moon, and we continue our landing mission.

https://www.isas.jaxa.jp/home/omotenashi/JHRCweb/jhrc.html

All the tweets  (https://twitter.com/OMOTENASHI_JAXA)up to now:

Quote
This is Hashimoto, the leader of the OMOTENASHI team. Twitter personnel are concentrating on recovery activities, and I will report back. After separation from the rocket, radio waves from the spacecraft were not stable, and telemetry at the NASA DSN Madrid station did not lock.

When I finally locked it and checked the status, the solar cells were facing the opposite direction of the sun and the spacecraft was rotating rapidly. Therefore, instead of using attitude control to direct the solar cells toward the sun, we decided to use a gas jet device to stop the rotation.

Considering that there was no power generation from the solar cells and the battery voltage continued to drop, we changed the operation from stopping the rotation, changed the direction of the rotation axis, and sprayed the gas jet so that the solar cells would face the sun. However, at the end of the Madrid station, the transmitter was turned off due to insufficient voltage. Since then, the transmission radio wave has not recovered.

OMOTENASHI has been developed in-house for 6 years. At present, we do not believe that any equipment is out of order, so we would like to recover our posture and achieve our mission.


This UHF operation plan is currently invalid.
Please wait for the next report regarding the future amateur radio operation plan.

The OMOTENASHI team is continuing recovery operations today.

If the rotation state changes and the solar cells are exposed to light, the spacecraft will restart. Once activated, it will automatically start transmitting radio waves, so we continue to check it every day.

If we can confirm the transmission radio wave, we will try attitude control to improve the sunlight reception condition. We are also considering driving the reaction wheel in manual mode to change the attitude. As long as there is a possibility of landing on the moon, we will continue to do what we can.

The next time I will tell you will be on the morning of the 21st.
I hope we can give you some good news, but in any case we will be doing the best we can at the moment.

Thank you all for your support. Unfortunately,
Currently, radio waves from the spacecraft cannot be received.

It is assumed that the orbit of the spacecraft has not changed much from when it separated from the rocket, but considering the possibility that the orbit was deviated and reception could not be performed, we also conducted a search operation by moving the direction of the antenna.

Also, we were planning to operate with the 64m antenna of Usuda station, but in order to use the 34m antenna of Uchinoura station, which has a wider antenna beam width, we exchanged the operating station with EQUULEUS (@EQUULEUS_ja).

At the moment, we cannot carry out the originally planned landing method, but if we can recover by the end of the day, we will decelerate with a solid rocket when passing the perilunar point (the point closest to the moon) and free fall to the surface of the moon. You can.
The perilunar passage is tonight around 24:00 JST.

Therefore, once the radio wave was received, we quickly confirmed the procedure for establishing 3-axis attitude control, preparing for landing, and transmitting the landing sequence, and prepared a command file.

Also, yesterday, we conducted an operation rehearsal using a spacecraft simulator to see if there were any problems with this procedure. The NASA DSN station has also secured an operational path for this time.

Until midnight today will be the last chance for the moon landing. We need to be prepared for a long-term battle, but we will make thorough preparations for the landing until tonight.

The announcement by the team leader this morning was also posted on the JHRC website (Japanese, English)

Regarding trying to identify lunar features, keep in mind we here on earth are just a few days from New Moon, which means what we're seeing from Orion that is lit is mostly farside.  If you look at the tracker animation, the dark spot near the bottom is Mare Orientale... which is just around the limb out of view from earth.  We also won't see much nearside features since it is mostly dark now.

The Orion spacecraft's Outbound Powered Flyby burn should now be underway. This burn occurs while Orion flying on the back side of the moon without a communications link with Earth.
The Orion main engine will burn for 2 minutes and 30 seconds.

The Orion spacecraft's Outbound Powered Flyby burn should be complete. This 2-minute, 30-second burn was expected to change the capsule's velocity by about 400 mph (643 km per hour) as it flies a few hundred miles over the far side of the moon.

Interesting that the supposedly TLM-driven animation shows a lunar altitude of 74 miles at close to AOS, implying it should have been even lower during the point of closest approach during LOS. Wonder where that kind of glitch comes from, if it's indeed what it is.

It was showing over 800 miles whilst the PAO were saying it was at closest approach 81.

Yeah, but that was a projection of the pre-burn trajectory, which might have been accurate. They apparently weren't simulating the maneuvers while in LOS.

The 70-something miles at AOS was supposed to be TLM-based.

During LOS, I think it was just animating the ballistic trajectory, not the expected trajectory using expected burn dV.
That's not so bad, but it's confusing, since they weren't commenting on that, and PAO kept reporting different data from what we saw on the screen.

IOW: They have some work to do in the clarity of their reporting/commentary.

- No MMT meeting on Sunday (good sign).
- Trying to act on feedback about expediting media content release.
- No concerns identified regarding exterior surveys.
- Two open items (funnies) regarding the STRs and the power system, as mentioned during the last briefing.
- Post-launch performance: SLS peformance was eyewatering.
     * The rocket was off from predictions <0.3% in all cases, when not exactly as expected, both CS and SRBs.
     * Missed insertion altitude = 3 nmi, 7 ft/s, well within error bands.
     * ICPS spot-on. RL-10 set a record for burn duration (18 mins).
     * No failures on stack, 5 observations but of no safety significance.
- Exploration Ground Systems performance:
     * Kindler, gentler loading operations performed as expected, together with team performing it.
     * Sound suppression water system and umbilical releases performed as expected.
     * All ML structures held well, all inspections passed.
     * Showed drone video of the ML post-launch. The interfaces are fine, the ML itself has damage but will be fine for Artemis II.

Surface of the ML, with just abrasion around the edges of the flame ducts. TSMs are pristine inside, all enclosures worked fine.

Infamous elevators: they're offline at the moment, took longer to perform inspections due to this.


Also showed the environment during launch from the PoV of a pad camera which got damaged.

Some damage also to pneumatic lines associated with GN2 and GHe, which caused the oxygen sensors at the pad to give off low oxygen readings, causing delays in getting personnel at the pad.

Two flight items were found at the pad: the throat plug from the SRBs, which is expected, but took a little time to map out its fragments. A piece of RTV material from the Orion S/C was also found on the pad's terrains, but it was unclear whether it was liberated at launch or was left over from the hurricane.

Earthrise did not show the Moon's surface clearly because the Moon's edge was in darkness from that perspective.
Seems like the "miles" mismatch between readings and PAO statements was conversion between nautical and statute miles. Closest approach at 81 mi as stated.

Expecting to take imagery of Apollo landing sites on the second flyover in a few days' time, starting the return leg of the mission.

Sarafin noting how they haven't seen "a single thing on the rocket or spacecraft that would make us question our reliability or our redundancy", asked whether this mission would have been "fine" were astronauts onboard. Some points didn't quite match the predictions, and this will be rolled into crewed flights, but this is in the context of the uncrewed, stress-test mission Artemis I is intended as.

Funnies for which anomaly resolution teams are active are, as mentioned during earlier briefings:

- Latching Current Limiters (LCLs) on the PDCUs are opening uncommanded. They're inline to the power feed between the solar arrays and the spacecraft, but there are two feeds into the PDCUs, so there's plenty of redundancy. There's an ART active in order to understand what the hardware is telling them, but not a real operational issue.

- RAM memory bits on the Star Trackers are having some issues that need rebooting due to single-upset events, with recovery going well every time. The STR fixes the RAM bit autonomously, flags the event, keeps working fine - then ground commands a reset to get it in a baseline state again. Having reports of similar behavior from other missions.

Two buffers throttling the data release for images:

This will be epic. Apollo 11 Tranquility Base photos looking hopeful on the return leg.

The discussion on the DSN data download time brings to mind Apollo's quad S-band high antenna array on the SM.  Has anyone heard about a future Orion upgrade with some kind dish antenna(s)?  Seems like that would help.

I recall seeing images of Tranquility Base from LRO, I'm anxious to see how these compare to that. You could see the walking paths they created as they explored.

No images as the near side was in complete darkness at the time of the flyby.

LRO imaged the Apollo 11 site from directly overhead.  The image from Orion may be at an angle, might answer the pesky question I get of whether the flag is standing.  The resolution of Orion's image(s) relative to LRO will indeed be interesting.

LunaH-Map looks like it's doing OK. 

Also - surely nobody really thinks a high flyover by Orion with a relatively wide angle camera is going to even remotely approach LRO/NAC resolution?  The Apollo 10 scouting images of the Apollo 11 site were probably far better than Orion's will be (it's not a mapping mission) but were much less detailed than LRO/NAC.  Also the flag situation is resolved, it fell over.  All other Apollo sites show standing flags in LRO (you can see the shadows), Apollo 11 does not.

First, kudos to Irene Klotz and Bill Harwood for doing their jobs as reporters and challenging NASA to be more forthcoming, and to NASA for responding positively to the feedback. The detail of Mike Serafin's post-launch analysis and release of the damage photos may not have happened without their feedback.

No. The phased-arrays are used for a reason. They're not going to stick back on an old-styled aimable antenna assembly ala Apollo.

They will, however, be adding an optical communications package (https://www.nasa.gov/directorates/heo/scan/opticalcommunications/o2o/) to Artemis II.

So I think I may have spotted some of the "easter eggs" hidden aboard @NASA_Orion (circled in red) - see thread below:

Firstly, here behind Snoopy, I think this is the US flag that flew on STS-135, lived on the ISS for 9 years, and was "captured" by @Astro_Doug and @AstroBehnken on the SpaceX Demo-2 mission in 2020.

We’ve been incredibly efficient with our use of propellant on #Artemis I so far. As of Nov. 21, we've used a total of 3.7K lbs of propellant, 76 lbs less than expected. We have 2.1K lbs of margin available over what we planned for use, an increase of 201 lbs from expected values.

[email protected]_Orion is on track to enter distant retrograde orbit on Friday, Nov 25, and will travel over 57K miles beyond the Moon, passing a record set by Apollo 13. It'll be the furthest a human-rated spacecraft has traveled from Earth, reaching a max distance of over 268K miles.

Earth Rise as Seen from Orion Spacecraft
art001m1203251305 Nov. 21, 2022 – Earth rises from behind the Moon in this video captured by a camera on one of Orion’s solar array wings. The video was taken at 8:05 a.m. EST on flight day six of the 25.5 day mission, shortly after the outbound powered flyby and six minutes after the spacecraft regained connection with NASA’s Deep Space Network.

Note
I think the SAW gopro is currently capturing video in a 4:3 aspect ratio but the clips are being released as 16:9 videos for some reason.
I reencoded the source video (https://images.nasa.gov/details-ART-SAW4_2022_325_1305_SHARED_art001m1203251305) from 1920x1080 to 1920x1440 to fix the aspect ratio

Tonight, flight controllers will test @NASA_Orion's search acquire and track (SAT) mode, as part of our additional test objectives. SAT mode will help us recover and maintain communications with Orion, should we ever lose communication with the spacecraft during the mission.
