more Starlinks from Cape
0037-EX-ST-2024  Mission 1912 Starlink Group 6-40
<snip>
[Launch NET Feb 14]
ASDS    North  25  41  37   West  75  5  42

The Florida Starlink mission expected to follow Starlink 6-39 could launch NET mid February.  Assuming that SpaceX continues, again, to launch its Florida Starlink Group 6's in ascending numerical order, this launch will be 6-40.  It is currently listed on NextSF with launch NET February, from either Kennedy LC-39A or Canaveral SLC-40, with recovery either aboard an ASDS or RLTS to LZ-1.

LC-39A is not available, due to the successive launch campaigns of IM-1 and Crew-8, so this launch will be from SLC-40.  Also, there is not (yet) a request to or approval from the FCC for RTLS landing.  Finally, we do not yet know if JRTI will be available for ASDS recovery.  (same for Starlink 6-41 and 6-42)

Edit Feb 3: JRTI will be available.

The next SpaceX Falcon 9 rocket will launch NASA's Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite from pad 40 on February 6 at 1:33 a.m. EST. The first stage will land back at the Cape about eight minutes after launch. A Falcon 9 will launch the Intuitive Machines & NASA IM-1 Nova-C commercial lunar lander from pad 39A on February 14 at 1 a.m. EST. The first stage will land back at the Cape about eight minutes after launch. Upcoming launches include more Starlink batches from pad 40. A Falcon 9 will launch the Telkomsat communications satellite for Indonesia from pad 40 on mid-late February TBD. A Falcon 9 will launch the next crew of four astronauts to the International Space Station, Crew-8, from pad 39A on February 22 at the earliest, around 3 a.m. EST, or around February 29-March 1 at midnight (the latter date if IM-1 proceeds as planned). The first stage will land back at the Cape about eight minutes after launch.

Do we expect any testing or sea trial for JRTI? If not, could JRTI do 6-40 on ~12th and Telkomsat HTS 113BT on 20th in order to allow ASOG to do 6-39 on 10th and 6-41 on ~18.

Perhaps 2 day turnarounds for pad is probably too optimistic yet even if Elon thought they could get it down to 24 hours this year?

SLC-40 launches:

PACE launched February 8 UTC, successful LZ-1 landing.

USSF-124/HBTSS is now scheduled for launch on February 14 UTC, with LZ-1 landing.

HTS-113BT is scheduled to launch February 20 UTC.  ASDS landing?  Both JRTI and ASOG are available.

Starlink 6-39 is scheduled to launch NET February 23 UTC (3 day pad turnaround?).  ASDS landing.

This would place the Starlink 6-40 launch NET February 27 or 28 (dependent on pad and ASDS turnarounds).  ASDS landing.

If Telkomsat HTS 113BT is on 20th and used droneship and 6-39 does too.

Then 8 day turnaround for ASDS doing Telkomsat means NET 28th. Crew launch planned for March 1st so cannot launch on 29th Feb. Everything has to go right to fit this in on Feb 28 else slips to March.

Perhaps a good opportunity to fit in a RTLS 27th ish?

A Falcon 9 will launch a Starlink batch from pad 40 on February 24 between 5-9 p.m. EST. A Falcon 9 will launch the next crew of four astronauts to the International Space Station, Crew-8, from pad 39A on March 1 at 12:04 a.m. EST (Saturn V Center tickets now on sale; 3.9 miles away closest possible viewing).

A new cancel-and-replace NGA Rocket Launching notice.

The times are moved a little less than 15 hours later, and not all of the days have a four-hour launch window now.

Additionally, the order of the coordinates in location A are shifted and a couple of them have minor changes.

L-1 launch weather forecast is 85% GO

A bit strange that this is apparently still scheduled on the range for before Crew-8

L-1 launch weather forecast is 85% GO

A bit strange that this is apparently still scheduled on the range for before Crew-8

Probably to allow for chances where the Crew-8 launch got called off some time before hand (might just be possible after looking at higher weather risks for ascent corridor abort recovery) - SpaceX then can substitute this to launch earlier.

The next SpaceX Falcon 9 rocket will launch a Starlink batch from pad 40 on February 28 at 10:30 a.m. EST or March 1 at 10:00 a.m. (could move up or back depending on Crew-8 [most likely ascent abort] weather). A Falcon 9 will launch the next crew of four astronauts to the International Space Station, Crew-8, from pad 39A on March 1 at 12:04 a.m. EST. The first stage will land back at the Cape about eight minutes after launch. A Falcon 9 will launch a Starlink batch from pad 40 on March 3 or 4. Upcoming launches include more Starlink batches. A Falcon 9 will launch the CRS-30 cargo Dragon resupply mission to the ISS from pad 40 on March 11 at 8:47 p.m. EDT. The first stage will land back at the Cape about eight minutes after launch. Upcoming launches include more Starlink batches. A Falcon 9 will launch the Eutelsat 36D television satellite from pad 40 on late March.

Cross-post re: why this launch may go on February 29:
[Crew-8] L-1 launch weather forecast is 85% GO
Note that the ascent corridor weather risk criteria is moderate to high on March 1, high on March 2, and moderate to high March 3.



Which first stage will be used for this launch?
(semi-rhetorical question)

Falcon 9 first stages are now apparently cleared for use up to twenty times for non-crewed launches, although that number is apparently more restricted for Cargo Dragon or Cygnus than these other payloads.

1064.6 and 1065.6 are the Falcon Heavy side boosters for Europa Clipper.

1072.1 and 1086.1 are assigned as the side boosters for GOES-U.  1083.1 is reserved for Crew-8.

1073.13 and 1076.11 may undergo modifications to become Falcon Heavy side boosters for a future launch, but both are currently available for "single-stick" launches.

Available first stages, with UTC date of most recent recovery:
1076.11  Jan 3
1073.13  Jan 15
1080.6    Jan 18
1062.19  Jan 28
1077.11  Jan 30
1081.5     Feb 8

Edit February 29: It's B1076.11.

With Crew-8 delayed to March 3rd UTC, this Starlink launch can go ahead today - and despite SpaceX has yet to tweet it, the mission page has confirmed this.

https://www.spacex.com/launches/mission/?missionId=sl-6-40

Quote
SpaceX is targeting Thursday, February 29 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. Liftoff is targeted for 10:30 a.m. ET, with backup opportunities available until 12:30 p.m. ET. If needed, additional opportunities are currently available on Friday, March 1 starting at 10:04 a.m. ET.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the 11th flight for the first stage booster supporting this mission, which previously launched CRS-26, OneWeb Launch 16, Intelsat IS-40e, O3b mPOWER, Ovzon 3, and five Starlink missions. (=B1076-11) Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.

From the burn pattern on the ASDS deck, it appears that the landings are distributed around a fixed offset.  The rusty mark is about half the radius of the inner circle towards the aft end.
Not only are they alighting on the deck every time, they are landing on a specific place on it.
This is some marvelous control system.
(Where’s the ASDS Landing Bingo contest now that I’ve figured this out?)

Given that deck has only seen one landing since the last time it was painted, I wouldn't do much analysis cause that can just be where the previous landing occurred. I'd take ASOG as the better example since it hasn't been painted in a long while.

If B1069 does have a super-power, it's the ability to withstand re-entry heat.  It did a roughly 3 second shorter re-entry burn, leaving 5970 m/s to be scrubbed off by the air, where this mission only left 5290 m/s or so.  Less fuel for re-entry means more fuel for boost, is my suspicion.

Good point.  Could also be a test of the higher speed reentry profile, which would require close inspection of B1069 after the flight to determine if the profile can be used universally.
