Discussion thread for Starlink v1.0 Flight 14.

Check the Starlink Index Thread for links to more Starlink information.

NSF Threads for Starlink v1.0 Flight 14: Discussion

Successful launch October 24, 2020 at 11:31pm EDT (15:31 UTC) on Falcon 9 (booster 1060.3) from SLC-40.  ASDS landing on JRTI was successful.  There was an earlier launch attempt on October 22 that was scrubbed due to a faulty camera on the launch vehicle.  Both fairing catchers sustained damage during the previous launch campaign and did not participate in the first launch attempt.  On the day of the launch Ms. Chief was dispatched to recover the fairings from the water.  The fairings may have been watched over by another ship, Big Stone Leader, while Ms. Chief was en route.  JRTI was towed by Lauren Foss.  Expected deployment orbit of approximately 260km.

Payload: A batch of 60 Starlink satellites.

Please use the Starlink Discussion Thread for all general discussion on Starlink.

From a previous mission's Press Kit:
Quote
Each Starlink satellite weights approximately 260 kg and features a compact, flat-panel design that minimizes volume, allowing for a dense launch stack to take full advantage of Falcon 9’s launch capabilities. With four powerful phased array and two parabolic antennas on each satellite ... At end of their life cycle, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event their propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years, significantly less than the hundreds or thousands of years required at higher altitudes. Further, Starlink components are designed for full demisability.

Starlink is targeting service in the Northern U.S. and Canada in 2020, rapidly expanding to near global coverage of the populated world by 2021. Additional information on the system can be found at starlink.com.

We have next active NOTAM in MELBOURNE information region south of Australia that is intended for S2 debris reentry of Starlink V1.0-L14 with primary launch date planned NET October 21.
That looks like next flight proven booster is cleared for launch before GPS's B1062. Probably Starlink/GPS missions swap on SLC-40.

Hazard areas indicate 2 Starlink missions will launch next week: Mission 14 from LC-39A on Sunday, 10/18, and Mission 15 from SLC-40 on Wednesday, 10/21. This means mission 15 will launch before GPS-III-SV04, which is still troubleshooting engine issues.

According to Next Spaceflight, booster 1060.3 is going to be used for this mission. I'm also a bit surprised here, I expected SpaceX to use 1049.7 or maybe 1059.5 for this launch.

Source: https://nextspaceflight.com/launches/details/2579

Previous launches:
GPS III SV03 (June 2020)
Starlink-12 (September 2020)

I the launch time holds (October 21, 16:36 UTC), just over 48 days between two launches, so there's a potential for a record here.

Look, we installed the #Fleetcam so we could stream the arrival and departure of boosters... technically, this counts!

This morning's Starlink launch can be seen in the background as "Just Read The Instructions" departs for its next mission.

Not required for internal payloads on a flown booster. Flight by flight determination for flown boosters. All maiden flight boosters are subject to the customary static fire at McGregor and the Flight Readiness Firing (Static Fire) at their assigned pad for that launch. The plan is to phase pad FRF SF's out and only be required to the Quality Assurance Verification Static Fire at McGregor for new boosters. If flight rate stays strong it negates most of the need for the FRF to verify pad systems through ignition sequence post start with shutdown.

Those documents have had the wrong date before.  The weather forecast has disappeared entirely from the Patrick AFB site now.  Probably a delay, but a direct confirmation would be nice.

Here's the update from the NGA removing the 21st.  Note that the 24th is listed twice (bolded by me).  This might have been meant to add the 25th as another hazard day, in which case I expect a "Corrected Copy" notice to be issued with the same notice number.  If it's just an inadvertent duplication, then a correction may not be issued.

The reasoning for firing up these 2 past missions before launch prob has to do with them checking the engines and making sure everything is fine and nothing is wrong that correlates with the GPS III stand down.

Wasn't the last flight a 7th launch for a booster?

So that one seems independent from from the GG issues.

If we do see a static fire here, I think it's because of the issues. a 3rd (?) flight is old hat to SpaceX now.

No, it was another 6th flight, B1051.6

B1049 and B1051 have both flown 6 times, there has not yet been a 7th flight.

The next most experienced booster is B1059, with 4 flights.

Here's the forecast referenced in SpaceX's tweet.

It's 50% GO with an additional high risk of unacceptable booster recovery weather.

Backup day is a bit better with 60% GO and a moderate risk of unacceptable booster recovery weather.

Will they recover the fairings for this mission?

I would guess they fish them from the water after the last mission's adventures.  We won't really know until we see the boats tomorrow.

Depends on if the nets are repaired or replaced in time.

SpaceXfleet has JRTI in position but no mention of the fairing catchers since offloading yesterday.

If the mission launches on time, it's going to be a booster turnaround record of 49d 03h 28m (Starlink-12 -> Starlink-15). The current record is 51d 02h 08m (Crew Demo-2 -> ANASIS-II).

MarineTraffic reports both fairing catchers still alongside the quay at Morehead City, North Carolina as of a few minutes ago (08:23 EDT / T-3h51m), and it's a good 8 hr trip to the LZ for them.

Hello,

Would this be the right place to ask whether anyone knows (and is able to say) whether the fairing halves for today' launch are new, or reused?

Or would this be something I need to ask in L2?

I'd like to be able to fill out an "unknown" item in Everyday Astronaut's prelaunch preview article.

Thanks, in advance,

Typically the fairings are new if they don’t give any history, but you should ask in L2 if you’d want confirmation for publication.

They have obviously lost a feed from the camera, and with no means to check if it has mechanically lost, cable loose, or just a failure within the unit, they decided to scrub.

Presumably, if it's a networked camera, they would want to exercise any or all other sensors that might be on that subnet if any.

Nobody wants either of the cameras aimed at the MVac to be flopping about near the sensitive bits during ascent, nor the payload cam. Or their cables. Or if it's a data multiplexing issue, what other telemetry might they lose at a critical time?

I concur, especially in the context of the engine trouble with B1062.

An abundance of caution coincides with risk management in this case.

Also gives a couple of additional days for repairs to the fairing catchers.

Space Force official: Launch scrubs are no reason to despair

Quote from: Spacenews
A streak of United Launch Alliance and SpaceX launch scrubs has frustrated rocket company executives and space aficionados. But Space Force launch managers are not discouraged, and in fact see scrubs as proof that systems are working like they should, Col. Douglas Pentecost said Oct. 22.

Or one of the internal cams.  Certainly don't want the LOX tank cam flopping about.

  Navigator and GO Searcher are being deployed for fairing recovery, replacing Ms. Tree and Ms. Chief for the Starlink mission.

Both ships are leaving right now but won't be able to get into position in time for launch tomorrow... which suggests a few days delay to Starlink.

That only applies to Chief/Tree coming from Morehead City. Searcher/Navigator are slower and coming from Port Canaveral which is further away.

It looks like economical cruising speed is around 20km/h, so it would take 36 hours to get 725km downrange. I can't find anything about top speed though.
Launches attended: Worldview-4 (Atlas V 401), Iridium NEXT Flight 1 (Falcon 9 FT), PAZ+Starlink (Falcon 9 FT), Arabsat-6A (Falcon Heavy)

A valid deduction.

However, might Navigator and GO Searcher retrieve the PLF halves from the water hours or a day after they splash down?  How long do fairing pieces float?  What is the sea state in the PLF recovery zone?

(God to Noah, via Bill Cosby: "How long can you tread water?")

EDIT: Well, I was partially correct. No one (?) considered SpaceX chartering another boat to babysit the floating PLF halves until one of the specialized SpaceX fleet can arrive on-scene, until later. :)

The "live time" on Thursday's unused webcast stream has been updated to reflect today's launch:

Quote
SpaceX is targeting Saturday, October 24 at 11:31 a.m. EDT, 15:31 UTC, for its fifteenth Starlink mission, which will launch 60 Starlink satellites to orbit. Falcon 9 will lift off from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, and a backup launch opportunity is available on Sunday, October 25 at 11:10 a.m. EDT, 15:10 UTC.

Falcon 9’s first stage previously supported the GPS III Space Vehicle 03 mission in June 2020 and a Starlink mission in September 2020. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Just Read the Instructions” droneship, which will be stationed in the Atlantic Ocean.

Since we no longer have dedicated update and discussion threads per mission, let me just say ... the live video of that landing looked “sporty.” :o. Not sure if it was the camera angle, the trajectory of the stage as it transitioned over the barge or what, but I sort of expected to see a flaming pile of debris when the image stabilized. Whew.

Good day for launch, bad day for cameras.

At mission time about +28 the camera rattles so much (vibration rate near its scan rate I think), that it looks as if the F9 is wildly gyrating for about 5 seconds. Just camera artifact.

And then at landing, the droneship camera gets itself ?blown around 90 degrees?

Ms. Chief is sailing offshore - going a mighty 19.4 knots - towards the splashdown site.

The ship will arrive in about 4 hours to hopefully scoop the fairing.

Specially chartered vessel 'Big Stone Leader' is already onsite and presumably has the task to babysit the fairing.

Falcon 9 launches SpaceX’s 100th successful flight →
https://www.spacex.com/updates/starlink-mission-10-24-2020/index.html

OCTOBER 24, 2020
STARLINK MISSION - SPACEX’S 100TH SUCCESSFUL FLIGHT

On Saturday, October 24 at 11:31 a.m. EDT, 11:31 UTC, SpaceX’s Falcon 9 rocket launched 60 Starlink satellites to orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station in Florida.

Falcon 9’s first stage previously supported the GPS III Space Vehicle 03 mission in June 2020 and a Starlink mission in September 2020. Following stage separation, SpaceX landed Falcon 9’s first stage on the “Just Read the Instructions” droneship, which was stationed in the Atlantic Ocean. The Starlink satellites deployed approximately 1 hour and 3 minutes after liftoff.

If you would like to receive updates on Starlink news and service availability in your area, please visit starlink.com.

This mission also marked the 100th successful flight of a Falcon rocket since Falcon 1 first flew to orbit in 2008.

SpaceX believes that fully and rapidly reusable rockets are the pivotal breakthrough needed to dramatically reduce the cost of access to space to enable people to travel to and live on other planets. While most rockets are expendable after launch — akin to throwing away an airplane after a one-way trip from Los Angeles to New York — SpaceX is working toward a future in which reusable rockets are the norm.

Of its now 100 successful flights of Falcon rockets, SpaceX has landed a Falcon first stage rocket booster 63 times and re-flown boosters 45 times. This year, SpaceX twice accomplished the sixth flight of an orbital rocket booster. And, in the ten years since its demonstration mission, Falcon 9 has become the most-flown operational rocket in the United States, overtaking expendable rockets that have been launching for decades.

The difficulty of precision landing an orbital rocket after it reenters Earth’s atmosphere at hypersonic velocity is not to be overlooked — SpaceX remains the only launch provider in the world capable of accomplishing this task. At 14 stories tall and traveling upwards of 1300 m/s (nearly 1 mi/s), stabilizing Falcon 9’s first stage booster for landing is like trying to balance a rubber broomstick on your hand in the middle of a hurricane. While recovery and re-flight of an orbital rocket booster may now seem routine, developing Falcon such that it would withstand reentry and return for landing was generally accepted as impossible — and SpaceX learned many lessons on the road to reusability.

SpaceX’s accomplishments with flight-proven rockets and spacecraft have allowed us to further advance the fleet’s reliability and reusability, as well as inform the development of Starship — SpaceX’s next-generation fully and rapidly reusable super heavy lift transportation system. Starship’s capability of full and rapid reuse will lower the cost of spaceflight to help humanity return to the Moon, travel to Mars, and ultimately become multi-planetary.

Since we no longer have dedicated update and discussion threads per mission, let me just say ... the live video of that landing looked “sporty.” :o. Not sure if it was the camera angle, the trajectory of the stage as it transitioned over the barge or what, but I sort of expected to see a flaming pile of debris when the image stabilized. Whew.

(MODS - please feel free to move/delete as necessary).
Wobbly camera. Landing was normal.

If anything it's one of the smoothest and best landings they've done, right in the centre of the droneship.

The cumulus cloud rule is based on a combination of the temperature at the cloud top, whether the cloud is precipitating, and field mill values.  NASA STD 4010 specifies the details.

I'm not a meteorologist, but generally speaking "low clouds" do not have to be cumulous clouds. The rules are intended to avoid launching into or through/around electrical storm cells, and cells with high potential for lightning and localized wind sheer. In addition to monitoring conditions with Doppler radar to track true storm cells and buildups, the Range also tracks electrical field potential to judge the risks of lightning discharges. If the electrical field potential is low, and there are no active storm cells around or building up in the launch corridor, there should be no constraints to launch simply as a result of relatively low clouds.

Another constraint related to low clouds applied when the Range required visual tracking as part of Range safety/vehicle destruct constraints but we are long past that for SpaceX. which uses an approved Autonomous Flight Termination System which will destroy the vehicle by itself if it veers substantially off its planned trajectory or if its heading rates exceed a very narrow margin indicating loss of control. Shuttle had other constraints about low clouds relating to RTLS aborts, thos don't apply either, obviously.

For some reason the Starlink L13 telemetry only commenced at T+07:24, but it made a welcome return for L14. The comparison this time is between L12 and L14, and the differences are becoming increasingly subtle, so I've increased the plot resolution a tad.

Those small profile differences include:
1. L14 spends about 4 seconds longer at the base of the bucket, and goes supersonic a couple of seconds later, at about a kilometre higher altitude.
2. L14 MECO is at some 48m/s slower, and 1.7km lower.
3. The L14 S2 more than makes up for this, with SECO 5m/s faster than L12. Most of that velocity appears to have gone into a slightly less elliptical coast insertion, rather than a higher apogee.

GO Searcher and GO Navigator have turned around and are returning to Port Canaveral.

The two ships were deployed yesterday for Starlink fairing recovery but were ultimately not required.

Ms. Chief completed repair work in North Carolina and was deployed at around T - 2 hours.

Fleet update:
It took the technicians roughly four hours to checkout and secure B1060 on the deck of JRTI putting the departure at roughly 6:00 pm ET. They are steadily making the trek back to Port Canaveral. Satellite tracking via @MarineTraffic.

Since SpaceX has reused water-landing fairings multiple times now, and given the issues they keep having with net captures, why are they still pursuing that technique?  Does anyone have any idea on the delta costs on water landings vs net-captured fairing refurb?

You need a ship to scoop the fairings up anyway, so why not attempt to catch them, while the ship is there?

Refurbishment costs are likely higher for fairings that landed in the ocean, but we don't know by how much.

1. Carbon fiber composites really don't like salt water. SpaceX has clearly been sealing them pretty well in order to reuse them, but one has to imagine that there is some cost to inspect / clean / refurbish that would rather be avoided.

2. Impact with the net is going to be gentler than impact with water. Also, wave action can damage the fairing. Capture with net avoids those stresses on the fairing.

They've definitely come up with some kind of viable solution (pardon the pun).

I don't know if I agree with that.  I assume (and we all know how well that can work) that the fairings are landing nose-first into the water at least at a zero angle of attack, if not nose-up.

We know of fairings that are damaged during capture attempts that I assume have been scrapped.  But, for the fairings that are intentionally allowed to water-land, how many of those have been scrapped?  This may be info that's just not available, but ISTM that water-landings have been pretty successful recently.

Have a good one,

A lot of fairings recovered from the water were heavily damaged. I’m sure someone at SX did a cost benefit analysis and decided that even recovering a single fairing would pay for the nets, arms, and boats.

This doesn't sync with my understandings where composites are often used for repairs that must stand up to salt water corrosion, the Americas Cup AC72s were largely carbon fiber composite, and even CF boats and road bikes seem to handle salt better than other materials with not much more than a rinse off with fresh water afterwards.

The issue is that the fairings are constructed as a honeycomb. So a ton of nooks and crannies for the sea water to infiltrate.

No signs of Falcon 9 second stages left in orbit during the v1-13 and v1-14 missions.  The v1-12 second stage is still up there, possibly set to fall from orbit on October 30.

The Starlinks are descending 3 or 4 times faster than the low density second stage, and as fast as the other Starlinks are ascending. They must be under control and power. They don’t seem to be simply “failed”.  Makes me wonder why they are being deorbited.


Perhaps this discussion should be moved from the launch thread to a Starlink thread after the second stage renters.

Can anybody share the status of the second stage used during this launch?  The last I saw was some conjecture that it would enter the atmosphere in an uncontrolled manner.

I don’t know enough about tracking individual space objects to find this answer out for myself.
