Thread for the Starlink 4-7 launch from Florida.

NSF Threads for Starlink 4-7: Discussion

Launch February 3, 2022 at 18:13 UTC (1:13 pm EST) from LC-39A on booster 1061-6.  ASDS landing was successful, aboard A Shortfall of Gravitas.

Payload 49 Starlink satellites to 53.2 degree inclination on SE trajectory.  Initial orbit of ~210x339km.  On the Starlink Group 4-5 webcast it was mentioned that the southeast trajectory is to increase the recovery weather availability for the booster and fairings during the winter months.

Quote
SpaceX is targeting Thursday, February 3 for a Falcon 9 launch of 49 Starlink satellites to low Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The instantaneous launch window is at 1:13 p.m. EST (18:13 UTC), and a backup opportunity is available on Friday, February 4 at 12:51 p.m. EST (17:51 UTC).

The booster supporting this mission previously launched Crew-1, Crew-2, SXM-8, CRS-23, and IXPE. Following stage separation, SpaceX will land Falcon 9’s first stage on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean. One fairing half previously supported five Starlink missions, and the other half previously supported Transporter-1 and two Starlink missions.

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

Two more Falcon 9 flights with Starlink satellites are slated this month, bringing the total tally to seven missions on the range schedule at Cape Canaveral. Launch dates for the next two Starlink missions were unavailable Thursday.

In a press release this week, the Space Force said five of the seven launches planned this month will head southeast or south from Cape Canaveral...[includes the two Starlink launches previously mentioned in quote]

Possible first stages for Starlink 4-7: 1052.3 or 1061.6.

No other stages will be/are known to be available yet.

These are also the possible first stages for CSG-2.

Whichever of the two that doesn't launch CSG-2, launches Starlink 4-7.

My >guess< regarding Static Fire or not would be:
No Static Fire.

(We on the outside do not know what the current disposition of B1069 is.  We have not yet seen 1053.3 with conversion work completed to single stick.)

(1051.12, 1063.4, and 1071.1 are on the west coast.)

Edited

Edit Jan 26: 1061.6, by deduction.

Edit Feb 1: 1061.6 confirmed.

Edit Feb 3: Successful launch and ASOG landing.  No Static Fire.

I agree, although I would also add B1061 as a possibility for Starlink 4-7.

A slip to the backup time would be just after sunset with the Sun at -4 degrees of elevation, which could make for a great “show” at staging.

L-3 weather forecast.  80% 'Go' for January 29.  90% 'Go' for January 30.  Booster Recovery Weather risk is High for January 29 and Moderate for January 30.  All other Additional Risk Criteria are Low.

Since this is a Starlink flight I expect they'll delay to get better recovery weather.

Since this is a Starlink flight I expect they'll delay to get better recovery weather.

If the weather prediction holds up then I would expect that. They also might delay to give priority to CSG-2.

CSG-2 FM2 will be launched as soon as weather is acceptable for sure, but they're two separate flight from two different launch pad.
CSG-2 as RTLS allows SpaceX to launch the two mission even in a relative short timeframe.


IMO the recovery weather is the key, despite of CSG-2...

B1052.3 is confirmed

It SHOULD be 1052, but on EDA's website is a guess. Austin, the writer, wrote on twitter earlier that "it seems to be 1052".

All signs are trending towards it, but in lack of HQ pics, (for me) it's not confirmed until SpaceX confirms! 😁

I do know B1052 for CSG-2 is correct, not sure about the booster for this mission tho.
