SpaceX Starlink Group 6-4 Launch

SpaceX plans to launch 22 Starlink V2 mini satellites into Generation 2 Group 6 on 2023-06-04 at 09:56 UTC. The launch will be from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. The first stage booster, B1078, will be making its third flight, after a turnaround time of 37 days since its last mission. The operational orbit will be 530 km circular at 43°.

This will be the fourth launch of Starlink v2.0 satellites, using the “Bus F9-2” configuration, also called “V2 mini”, with satellites of 800 kg and 4.1×2.7 metres size, able to fit in the Falcon 9 payload fairing, but with only 22 per launch. This is a scaled down version of the 2000 kg v2.0 Bus Starship version designed to be launched by Starship, but is said to provide three to four times the bandwidth per satellite of the operational v1.0 and v1.5 satellites. Weather is forecast as 45% favourable for launch. If weather causes a delay at the prime launch time, additional launch opportunities are available at 10:46 UTC and 11:36 UTC on the 4th and three opportunities on the 5th.
