SpaceX Starlink Group 4-20/Sherpa LTC Launch

SpaceX plans to launch 51 Starlink satellites into Shell 4, with an eventual 540 km circular service orbit at 53.22° inclination, on 2022-09-05 at 02:09 UTC, which will be in the evening of the 4th in western hemisphere time zones. The launch will also carry Spaceflight Inc.'s Sherpa-LTC orbital transfer vehicle, which was scheduled to fly on the Transporter-4 rideshare mission in April 2022 but missed the launch deadline. This will be the seventh flight of Falcon 9 booster B1052, including its first two launches as a Falcon Heavy side booster, with a turn-around time of 32 days since its first flight. The launch will be from Space Launch Complex 40 in Florida. Weather is currently forecast as 80% favourable for launch.
