Thread for the Starlink 5-4 group launch.

NSF Threads for Starlink 5-4: Discussion

Launch February 12, 2023 at 12:10:10 am EST / 05:10:10 UTC, from Canaveral SLC-40, on booster 1062-12.  The first stage is expected to land aboard an ASDS.

Main payload: 55 Starlink satellites, also the Starlink upgraded network Flight 4.

Launch to a mid-inclination orbit on a southeastern trajectory.  Initial orbit is 298 x 339 km at 43 degrees.

Starlink v1.5 satellite mass is now about 300kg after the addition of laser ISL terminals.

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

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

Yes, now all January and February missions are set for those months, the change of year makes it necessary to change many launches due to "NET 2023".

Cross-post:
Perhaps, Starlink 6-1 will launch in early February, from LC-39A, after Starlink 5-3 on February 1 January 31, and before Crew-6 on February 26?

(Or Starlink 5-4?)

Edit: There may be another, brief launch opportunity at SLC-40 between Amazonas Nexus on February 5 and Inmarsat 6 F2 on February 18 later in the month.

Edit Jan 26: Both launches have been assigned first stages, indicating both launches are in the near future.

Edit Feb 2: It's Starlink 5-4 at SLC-40 mid-month.

NGA Rocket Launching notice and two Space Debris notices (the same notice for two different navigational areas).

Maps from the NGA notices. ASDS 661km downrange.
« Last Edit: 02/06/2023 08:47 pm by OneSpeed »

Per https://www.portcanaveralwebcam.com/, ASOG is still in port.  Typically ASDS departs for East Coast Starlink missions approximately 4 days before launch, which would have been just after midnight last night.  Given no ASDS departure, and current 4.1d between Amazonas Nexus and 2023 Feb 11 @ 12:07am EC SL5-4 launch time (current record of 5.4d turnaround time at SLC-40), it's possible this mission gets pushed back.

(sorry for previous poorly researched post)

L-3 weather forecast. 30% 'Go' for February 11/12.  60% 'Go' for February 12/13.  Upper-Level Wind Shear risk is Moderate for both days.  All other Additional Risk Criteria are Low.

Inmarsat launch being pushed by a day could indicate that SpaceX has already decided not to attempt the Starlink launch on the 12th due to the expected bad weather.

Just my speculation, though.

SpaceX is targeting Sunday, February 12 at 12:10 a.m. ET (05:10 UTC) for a Falcon 9 launch of 55 Starlink satellites to low-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. If needed, there are additional launch opportunities the same day at 1:51 a.m. ET (06:51 UTC), and 3:32 a.m. ET (08:32 UTC), with backup opportunities also available on Sunday, February 12 at 11:55 p.m. ET (04:55 UTC on February 13) and on Monday, February 13 at 1:39 a.m. ET (06:39 UTC), and 3:07 a.m. ET (08:07 UTC).

The first stage booster supporting this mission previously launched GPS III Space Vehicle 04, GPS III Space Vehicle 05, Inspiration4, Ax-1, Nilesat 301, and six Starlink missions. Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean.

A live webcast of this mission will begin about five minutes prior to liftoff.

If a 20% chance of acceptable weather materializes tonight, SpaceX will break its pad turnaround record with the first of two Starlink launches this week.

Group 5-4 is currently targeting liftoff at 12:10 AM EST (05:10 UTC).

This is the 97th consecutive successful landing since the last landing failure for a Falcon booster. 97 is also the number of launches Atlas V has performed. Falcon landing reliability has reached the launch reliability of some of the most reliable rockets in the world.

Here is a comparison of the webcast telemetry from the Starlink 5-1 and 5-4 missions.

The outstanding difference is the altitude at injection to the coast orbit. Previous shell 5 missions have all inserted at 211-230km, but this mission injected at 152km, lower than any previous SpaceX mission I can find. A quick search suggests the previous lowest altitude was around 164km for several GTO missions like Amazonas Nexus.

This not exceptionally low by historical standards - flight that will go quickly go higher often use (and profit from) very low parking orbits.  Apollo 17's perigee was 147 km (91.2 miles).

Well-traveled SpaceX Falcon9 booster B1062 has returned to Port Canaveral.

First launched in November, 2020, that booster has been to space and back 12 times; two of those trips were for crewed missions (@inspiration4x & @Axiom_Space 1).

Welcome home, B1062!

Apparently there is “a little bit of evidence of combustion in an engine bay on the booster" during this mission:

Quote
He added NASA was also analyzing data from all Falcon 9 launches, citing a Starlink mission earlier in the month where there was “a little bit of evidence of combustion” in an engine bay on the booster. That booster was on its twelfth mission, while the Falcon 9 booster flying Crew-6 will be making its first launch.
