Longer than expected due to some alignment issues and the lack of KU to provide views to the ground.

ATK release:

Dulles, Virginia 25 March 2016 – Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, today announced that the S.S. Rick Husband CygnusTM spacecraft successfully completed its rendezvous and berthing procedures with the International Space Station (ISS) earlier this morning. This marks the company’s fifth successful berthing with the orbiting laboratory, and the fourth under NASA’s Commercial Resupply Services (CRS) contract.

Cygnus launched aboard a United Launch Alliance (ULA) Atlas V rocket on March 22 from Cape Canaveral Air Force Station, Florida. The spacecraft completed a series of thruster firings and other maneuvers over the past few days to bring the spacecraft in close proximity to the ISS. When it was approximately 30 feet from the ISS, crew members grappled Cygnus with the Station’s robotic arm at 6:51 a.m. (EDT). The spacecraft was then guided to its berthing port on the nadir side of the Unity module of the ISS where installation concluded at 10:52 a.m. (EDT).

“As we accomplish our fifth Cygnus berthing to the ISS, we celebrate the completion of a primary mission objective for OA-6,” said Frank Culbertson, President of Orbital ATK’s Space Systems Group. “Our flexible Cygnus spacecraft has a lot of work left to do. Following its stay at the ISS, and for the first time, we will undertake three experiments onboard the unmanned spacecraft.”

The crew plans to open the Cygnus hatch and make initial ingress into its cargo module tomorrow to unload the cargo, including food, clothing, crew supplies, spare parts, laboratory equipment and scientific experiments. Cygnus will remain berthed at the ISS for approximately two months before departing with approximately 4,400 pounds (2,000 kilograms) of disposable cargo.

Following departure from the ISS, Cygnus will conduct three payload mission objectives as part of its flight program. Using a deployer provided by NanoRacks, the S.S. Rick Husband will place five CubeSats into orbit to conduct their own autonomous missions. Onboard Cygnus, the Spacecraft Fire Experiment-I (Saffire-I) will intentionally light a large-scale fire that will grow and advance until it burns itself out. The final experiment to take place aboard Cygnus will be the Reentry Breakup Recorder (REBR). The ISS crew will install the REBR experiment on Cygnus as they pack the spacecraft with disposal cargo. REBR will measure and record data during Cygnus’ safe destructive reentry into Earth’s atmosphere.

Orbital ATK has two additional CRS missions scheduled in 2016 to support NASA’s ISS cargo and payload mission needs. Following an Antares launch vehicle full-power hot-fire test, flight operations for Cygnus and Antares will resume mid-year from NASA’s Wallops Flight Facility in eastern Virginia. Under the CRS contract with NASA, Orbital ATK will deliver approximately 59,000 pounds (26,800 kilograms) of cargo to the ISS over 10 missions through 2018. Beginning in 2019, Orbital ATK will carry out a minimum of six initial cargo missions under NASA’s recently awarded CRS-2 contract.

B-roll and animation footage for the mission can be found here:  http://www.orbitalatk.com/news-room/bmc/#.

Longer than expected due to some alignment issues and the lack of KU to provide views to the ground.
Might this circumstance be an argument for NASA getting more time on their own TDRS network?

Or for more TDRS satellites?

Or for arranging for some "surge" capability with a commercial provider?

I imagine the communications load to and from ISS will only increase in the future.

Tim Kopra called down that the hatch to Cygnus is open and that it looks great.  He had nice words to say about Rick Husband and his family although once again the words sounded like they were prepped by PAO.  There was no video of the event on the ISS streaming feed so we'll have to wait for NASA to show us the event when they feel like it or more likely when one of the crew post photos via social media...

This discussion has been well wrung out.  There are 6 fully operational TDRS satellites, at least, in the network that should provide nearly 100% coverage of the ISS. NASA is not the primary user, DOD is, and NASA definitely does not have priority on the network they reportedly own and operate, DOD does.

As usual, the crew are wearing protective masks and goggles inside Cygnus in case of loose debris floating in the vehicle.  Sounds like they are anxious to take it off but have 36 more minutes of required wear time.

1 hour into unpack and the crew already has an item that won't fit in the designated storage location.  This is common during the juggling act of trying to unload items into limited ISS locations already full of items needed for current operations and designated for disposal. A problem this early is unusual and suggests the ground still doesn't have a complete understanding of the situation on the station, despite considerable crew time and systems (Inventory Management System-IMS) dedicated to tracking the on-board status.

Well, after this Cygnus, they'll have a Progress to unpack next week, and a Dragon to unpack the week after that -- so they had better find some places to stash stuff!  I get the feeling that cargo unloading is pretty much all the ISS crew is going to be doing over the next month or so.

And they don't get to use their new inflatable closet until the very last one.  Could have planned that better, LOL!

Has ISS ever received three cargo shipments in a space of less than a month before?  This will, the gods permit, be three in less than three weeks.  Twelve tons of cargo.  Maybe this should be relabeled Expedition Cargo...

One sort of weird question on unpack for anyone to chime in on.  The crew asked if they could trash two layers of bubble wrap on an item. They were told they could.  Why not "pop" that bubble wrap like so many kids enjoy doing?  It would seem to accomplish two positive things.  First, release whatever is in the bubbles, presumably normal air, into the cabin, free of charge.  Second it would reduce the volume of trash needing to be stowed. A curious mind want's to know :)

Hmmm...  You wouldn't ask that kind of question unless there was a possibility that the bubble wrap was scheduled to be used to pad some downmass cargo, somewhere down the line.

Remember, until it gets stuffed in a Progress or a Cygnus or one of those other cargo vessels that serve as trash dumps for entry-incineration, no trash actually goes away.  Just putting the bubble wrap into a trash bag wouldn't make it ultimately unavailable for re-use later, if need arose.  So, in this case, "trashing" may mean "reduce to a non-functional state," i.s., popping.

Occasionally, when shipments get backed up, such as in this case with US cargo resupply.  It's not likely to be desired given the disruption to lab work.

Another case was with the slips of Shuttle STS-133, with four in January/February 2011 (HTV, Progress, ATV, Shuttle).

My uneducated guess: that although the bubble wrap would have likely undergone sterilization, you can never be too safe with the contents of the air in the bubble? It's a stretch, as I would believe that the wrapping meets strict standards for space use.

But Doug's explanation seems more logical: even though it's intended trash, it's never trash until it goes into the spacecraft for disposal. You never know if an ORU or other item needs to be returned in a Dragon & could make use of it.

Thanks for the answers.  I have heard of packing material, more specifically foam, set aside on ground direction specifically for later use, planned or not, with items being returned.  After listening to numerous transfer discussions, trash means disposal, not save for future use.

Could it also be a time vs cost thing? How long will it take to pop every bubble. Quite a bit if its small bubbles!

Given the context of unpacking in tight time constraints (3 shipments in 3 weekends), I would take this question to mean 'Do I need to spend time to open this neatly, saving the bubble wrap, or can I just tear through the plastic and be done?'

Can't they just do what my kids used to do when we have a large amount of bubble wrap to dispose of?

Occasionally, when shipments get backed up, such as in this case with US cargo resupply.  It's not likely to be desired given the disruption to lab work.

Another case was with the slips of Shuttle STS-133, with four in January/February 2011 (HTV, Progress, ATV, Shuttle)

True, but in the case of STS-133 you had a surge of crew members to help with moving cargo and extra volume to store stuff (PMM wasnt entirely full yet, and you had the orbiter's crew module and airlock)

NASA TV to Broadcast U.S. Cargo Ship Departure from Space Station


After delivering almost 7,500 pounds of cargo to support dozens of science experiments from around the world, the Orbital ATK Cygnus cargo spacecraft is set to leave the International Space Station Tuesday, June 14. NASA Television will provide live coverage of Cygnus' departure beginning at 9 a.m. EDT.

Ground controllers will detach the Cygnus spacecraft, which arrived at the station March 26, from the Earth-facing side of the station's Unity module using the Canadarm2 robotic arm. Robotics controllers will maneuver Cygnus into place and Expedition 47 robotic arm operators Tim Kopra of NASA and Tim Peake of ESA (European Space Agency) will give the command for its 9:30 a.m. release.

Five hours after departure, the Saffire-I https://www.nasa.gov/press-release/nasa-pursues-burning-desire-to-study-fire-safety-in-space
 experiment will take place onboard the uncrewed cargo craft. Saffire-I provides a new way to study a realistic fire on a spacecraft. This hasn’t been possible in the past because the risks for performing such studies on crewed spacecraft are too high. Instruments on the returning Cygnus will measure flame growth, oxygen use and more. Results could determine microgravity flammability limits for several spacecraft materials, help to validate NASA’s material selection criteria, and help scientists understand how microgravity and limited oxygen affect flame size. The investigation is crucial for the safety of current and future space missions.

Cygnus also will release five LEMUR CubeSats http://www.nasa.gov/mission_pages/station/research/experiments/2349.html  from an external deployer June 15, part of a remote sensing satellite constellation that provides global ship tracking and weather monitoring. The vehicle will remain in orbit until Wednesday, June 22, when its engines will fire twice, pushing it into Earth's atmosphere where it will burn up over the Pacific Ocean. NASA TV will not provide a live broadcast of the Cygnus deorbit burn and re-entry.

Experiments delivered on Cygnus
http://www.nasa.gov/mission_pages/station/research/news/crs6_science
 supported NASA and other research investigations during Expeditions 47 and 48, including studies in biology, biotechnology, physical science and Earth science -- research that impacts life on Earth, and also will help us on the journey to Mars. Investigations studied realistic fire scenarios on a space vehicle, enabled the first space-based observations of meteors entering Earth’s atmosphere from space, explored how regolith behaves and moves in microgravity, tested a gecko-inspired adhesive gripping device
http://www.nasa.gov/jpl/gecko-grippers-moving-on-up
 that can stick on command in the harsh environment of space, and added a new 3-D printer in microgravity.

The Cygnus resupply craft launched March 22
http://www.nasa.gov/press-release/nasa-sends-fire-meteor-experiments-to-international-space-station-on-commercial-cargo
 on a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station, Florida, for the company’s fifth NASA-contracted commercial resupply mission.

The press release says OA-6 is releasing five Lemur cubesats, while it was previously reported  by jcm that there are four cubesats (Theresacondor, Kane, Nick-Allain and Jeff). I guess we'll soon find out which is correct.

Both is correct:
Four Lemurs were deployed via the ISS airlock (Theresacondor, Kane, Nick-Allain and Jeff) and five more will be deployed directly from Cygnus from the new external deployer.

Hmm... in another NRCSD?  it seems like it would make more sense if they were on the external deployer
with the Lemurs. Like the internal ones, the external one seems like it can carry 16 3U cubesats;
5 Lemur + 8 Flock makes 13, so there could even be 3 more.

Or maybe the press release tells it all and the deployer is mostly empty this time.

Cygnus Departure Prep:

In preparation for Cygnus unberth and departure, the crew installed the Air Revitalization System (ARS), de-routed the Intermodule Ventilation (IMV) duct, removed handrails and completed radial port closeout and closed the hatch. They installed N1 Nadir Control Panel Assembly (CPA) and configured Cygnus/N1 vestibule for de-mate. They also relocated the Portable Computer System and cables from the N2 Utility Outlet Panel (UOP) to the Cupola UOP which will provide command redundancy during departure operations. Unberth is scheduled for tomorrow at 6:30AM CDT with release at 8:30 CDT.

This FCC document, issued after the first 8 Flock-2e and -2e' were deployed, tells, that 8 more Flock-2e and 16 more Flock-2e' remain on the ISS.

So it is likely, that the Cygnus external deployer holds only the 5 Lemur-2 sats.

It's a fitting end that the S.S. Rick Husband has an extended mission. First, the on-board fire safety experiments but also delivery of a few Cubesats before he returns to the fire once more, deliberately this time, as one last experiment sends information on the vehicle's destructive re-entry.

Orbital ATK sure knows how to pick their names, don't you think?

Congratulations to Orbital ATK and NASA. Looking forward to the re-dawning of age of Antares.

Orbital ATK's Cygnus Spacecraft Begins Next Phase of OA-6 Mission, Conducting Science in Space

Cygnus Departs International Space Station Today After Successfully Delivering and Removing Vital Cargo

The “S.S. Rick Husband” Begins Series of Experiments, Marking First Time Cygnus Used as a Science Platform

Dulles, Virginia 14 June 2016 – Orbital ATK, Inc. (NYSE: OA), a global leader in aerospace and defense technologies, today announced that the “S.S. Rick Husband” Cygnus™ spacecraft successfully departed from the International Space Station at 9:30 a.m. EDT, completing an 81-day stay at the orbiting laboratory. The mission, known as OA-6, began on March 22, 2016 when Cygnus launched aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station, Florida. Cygnus delivered 7,900 pounds (3,600 kilograms) of cargo and science experiments to astronauts aboard the station. Prior to its departure, the astronauts loaded the unmanned cargo module with approximately 4,087 pounds (1,854 kilograms) of items for disposal.

Orbital ATK’s fifth mission under NASA’s Commercial Resupply Services-1 (CRS-1) contract now begins its second phase before the planned reentry of Cygnus into Earth’s atmosphere. Cygnus will conduct three, in-orbit science experiments: the Spacecraft Fire Experiment-I (Saffire-I), the deployment of five CubeSat satellites from the NanoRacks CubeSat Deployer and the Reentry Breakup Recorder (REBR) test.

“Cygnus had a successful, two-and-a-half-month stay at the International Space Station, delivering vital cargo to the astronauts,” said Frank Culbertson, President of Orbital ATK’s Space Systems Group. “Now, the work continues as we demonstrate expanded capabilities for Cygnus beyond its core cargo delivery function. The next phase of this mission marks the first time that Cygnus will serve as a research platform to support science experiments that enable deep space exploration. Our ability to conduct these tests further highlights the versatility and flexibility that Cygnus offers to our customers.”

The Spacecraft Fire Experiment-I (Saffire-I) will feature the first of three tests to study the behavior of large fires in microgravity. Following departure from the International Space Station, engineers will remotely conduct the first Saffire experiment. Onboard Cygnus, the experiment developed at NASA’s Glenn Research Center with the support of NASA’s Advanced Exploration Systems Division will intentionally ignite and record a large-scale fire that will grow and advance until it burns itself out.
     
Next, using a deployer provided by NanoRacks, the “S.S. Rick Husband” will place five CubeSats into orbit to conduct their own autonomous missions.

The final experiment to take place aboard Cygnus features the Reentry Breakup Recorder (REBR).  REBR will measure and record data during Cygnus’ safe destructive reentry into Earth’s atmosphere. The scheduled date for reentry is June 22, officially ending the OA-6 mission.

Stay informed with real-time updates on the science experiments aboard Cygnus through Orbital ATK’s Twitter account: https://twitter.com/OrbitalATK.

Did the fire burn faster or slower than they expected?

(Yes, yes, I realize this could take months to get anything remotely publishable, so I would like someone who actually knows about this and is involved with it to answer...)

As of 6/19, Heavens Above listed Cygnus in a 388 by 389 km orbit, while n2yo said it was at 406 km.  These straddle the orbit of the ISS, which is H-A listed as 403 by 403 km. 

Regardless of which of these is more accurate, it does not appear that Cygnus went to a higher altitude after departing the ISS, which would greatly increase the orbital lifetime of the cubesats.  Conversely, descending even a few kilometers would eliminate the possibility of the cubesats later hitting the ISS, even if such a hit would be a less than walking speed.  This would be in accord with NASA's extreme (and probably appropriate) risk aversion for the irreplaceable ISS and crew.

The cubesats do not yet show up in either of those databases, or in a few others I have checked, so it can't yet be said if they were released at, above, or below the altitude of the ISS. (or when they were released)  If someone finds them listed and can post their orbits, it would be appreciated.

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

From ISS Expedition-48 thread (my bold):

ISS Daily Summary Report – 06/21/16

Posted on June 21, 2016 at 4:00 pm by HQ.
 
NanoRacks CubeSat Deployer- External (NRCSD-E) Operations: Following Cygnus unberth last week, today NRCSD-E conducted post departure satellite deployments prior to Cygnus re-entry tomorrow, June 22. This set of cubesats includes 3 deployment silos containing a total of 5 LEMUR satellites.  Two out of three silos (four out of five satellites) were successfully deployed. The Orbital team downlinked and reviewed imagery to ascertain why one of the CubeSats did not deploy. Further troubleshooting is ongoing. The LEMUR satellites are equipped with payloads to provide two primary data products: AIS Data (Maritime Domain Awareness) and GPS-RO Data (Weather). NRCSD-E is a mechanical separation system for small U-class satellites designed specifically to interface with the Orbital-ATK Cygnus cargo resupply vehicle. It consists of an array of up to six individual 6U deployers contained within one mechanical housing that releases the CubeSats from Cygnus after it has completed its primary mission and departed the ISS.

It seems as if every single reentry experiment is designed to fail. Think about it: ATV-5 had a reentry experiment, but that failed as well.

I doubt if they deliberately design them to fail. :D
It probably does point to the need to change how or where the re-entry experiment container is located, or if it is in fact an overall poor design/implementation and needs a complete overhaul.

Take a look at highlights from our OA-6 mission, which concluded on June 22, 2016, three months after its launch aboard a ULA Atlas V rocket. The S.S. Rick Husband Cygnus spacecraft, named for the late space shuttle commander, remained attached to the International Space Station for 81 days while the crew removed 7,900 pounds of cargo then filled it with materials for disposal. After it unberthed from the space station on June 14, the spacecraft hosted two scientific experiments and deployed 4 CubeSats from its NanoRacks CubeSat Deployer. Congratulations on another successful mission, Cygnus!
