SpaceX F9 : Starlink v1.0 L22 : CCSFS SLC-40 : 24 March 2021 (0828 UTC)

Discussion thread for Starlink v1.0 Launch 22

NSF Threads for Starlink v1.0 L22: Discussion
NSF Articles for Starlink v1.0 L22: https://www.nasaspaceflight.com/2021/03/falcon-9-starlink-l22-liftoff/

Launched successfully 24 March 2021 at 4:28am EDT (0828 UTC) on Falcon 9 (booster 1060-6) from CCSFS SLC-40. ASDS landing was successful on OCISLY, towed by tugboat Finn Falgout. Recovery support ship was GO Quest. Fairing recovery from the water by MV Shelia Bordelon was successful.

Payload: A batch of 60 Starlink satellites. Expected deployment orbit of approximately 284x258 km.

The Falcon 9 first stage rocket booster supporting this mission previously supported launch of the GPS-III Space Vehicle 03 and Turksat 5A missions in addition to three Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing supported the Sentinel-6A mission and the other supported a previous Starlink mission.

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

L2 SpaceX:
https://forum.nasaspaceflight.com/index.php?board=60.0

From a previous mission's Press Kit:

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 to near global coverage of the populated world by 2021. Additional information on the system can be found at starlink.com.

FALCON 9
The next SpaceX Falcon 9 rocket from Cape Canaveral will launch the twentieth Starlink internet satellite batch from pad 39A on March 4 at either 3:24am or 5:42am EST. Then, a Falcon 9 will launch the twenty-first Starlink batch from pad 40 on March 7 at 10:41pm EST. The launch time for Starlink missions gets approx. 20-22 minutes earlier each day. A Falcon 9 will launch the twenty-second Starlink batch from pad 39A on March TBD. Upcoming launches include Starlink batches on March TBD. The next Crew Dragon carrying four astronauts to the International Space Station is targeted for late April around 6am EDT. Sunrise is 6:49am. The launch time gets 22-26 minutes earlier each day.

[oldAtlas_Eguy]

For a flight in March there are 2 boosters available. But one of them them would be used by L21 leaving the other available to be used by L22.

The primary  restriction is site resources. SpaceX Navy/ASDS availability and the pad turnaround of a nominal 11 to 14 days for a launch of ~24 March to the very end of March. Based on when L20 actually launches.

SFN Launch Schedule, dated March 9:
Confirms launch from CCSFS SLC-40.
No mention yet of the first stage to be used, static fire or no static fire, or launch date.

SpaceX has at least two more Starlink missions scheduled for launch before the end of March, and possibly more.

https://nextspaceflight.com/launches/details/2677

Since booster availability would make it very interesting if another launch was done after this in March. This should be the last for March.

But this launch in the ~last week of March would make the total for Q1 2021 at 9 launches.

Here are the new NGA notices along with the full set of estimated launch times.

Primary Day = Wednesday, March 24 at ~08:38 UTC.
Backup Day #1 = Thursday, March 25 at ~08:16 UTC.
Backup Day #2 = Friday, March 26 at ~07:55 UTC.
Backup Day #3 = Saturday, March 27 at ~07:33 UTC.
Backup Day #4 = Sunday, March 28 at ~07:12 UTC.
Backup Day #5 = Monday, March 29 at ~06:50 UTC.
Backup Day #6 = Tuesday, March 30 at ~06:28 UTC.

Based on the validity period of the weather forecast, I've adjusted my estimated launch times, which now also brings my Primary Day launch time in agreement with Next Spaceflight, Spaceflight Now, and Ben Cooper.

I've also enhanced my offset rules for NGA notices for better accuracy in the future.

Primary Day = Wednesday, March 24 at ~08:58 UTC.

Progress so far on fairing recovery vessel Shelia Bordelon. They have a bit to go to pass the booster LZ then about 100 km past that for the fairing sweet spot. No update on OCISLY as Finn is a hard tug to track without AIS. #Starlink #SpaceXFleet

Falcon 9 launch of 60 Starlink satellites is targeted for tomorrow, March 24 at 4:28 a.m. EDT from SLC-40 in Florida → spacex.com/launches

[FutureSpaceTourist]

[scr00chy]

Visual mission profile with a cute little Shelia Bordelon

[Jansen]

SpaceX is targeting Wednesday, March 24 for launch of 60 Starlink satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous window is at 4:28 a.m. EDT, or 8:28 UTC, and a backup opportunity is available on Thursday, March 25 at 4:06 a.m. EDT, or 8:06 UTC.

The Falcon 9 first stage rocket booster supporting this mission previously supported launch of the GPS-III Space Vehicle 03 and Turksat 5A missions in addition to three Starlink missions. Following stage separation, SpaceX will land Falcon 9’s first stage on the “Of Course I Still Love You” droneship, which will be located in the Atlantic Ocean. One half of Falcon 9’s fairing supported the Sentinel-6A mission and the other supported a previous Starlink mission.

[scdavis]

{... counts missions listed...} Huh, only 5 missions so far - it hasn't been used much yet, it's almost new.

... That was actually my internal thought process. Then I stopped and considered what a strange response that was! Did anyone else respond that way?

[ZachS09]

Having subtracted T.S. Kelso's estimated Starlink deployment time (09:32:22 UTC) by the total mission duration (1 hour, 3 minutes, 52 seconds), the launch time should be at 08:28:30 UTC (4:28:30 AM Eastern).

[tgio]

What's the difference between "flight with a flight proven booster" and "re-flight of a booster"?

The difference might be that "flight with a flight proven booster" specifies Falcon 9. The Falcon Heavy test flight and STP-2 missions both had previously-flown side boosters, which would count as booster reflights but not as "Falcon 9 flights with a flight proven booster," and so would account for the difference between the numbers.

What's the difference between "flight with a flight proven booster" and "re-flight of a booster"?

One is overall, the other is this year, otherwise the same thing.

IOW
A Falcon Heavy launch with previous flown boosters increases the "flight with a flight proven booster" count by one but increases the "re-flight of a booster" count by two.
The difference of 2 in the counts means two Heavy launches have 2 re-flown boosters each, as tgio said.

Here is a comparison between the first stage telemetry for Starlink L21 and L22. The main differences are:

1. The vee-shaped throttle bucket of L21 compared to the flat bottomed bucket of L22.
2. The slightly lower acceleration of the life leader L21 B1051.9 booster from about T+110s, resulting in MECO a couple of seconds later than its B1060.6 junior.

Falcon 9 illuminates the Space Coast on its 6th flight.

B1060 got its start flying a GPS-III satellite, with Turksat 5A and a few Starlinks sprinkled in there.

After a successful landing on OCISLY, we’ll see her back in port in a few days!

Also first time I remember seeing simultaneous stage 1 and stage 2 views during stage separation.  A couple of new tricks!

I suppose the question they should be asking themselves is, what does a 2nd stage reentry after a successful de-orbit burn look like.
