This week SpaceX is preparing to launch a fresh branch of 48 Starlink satellites on top of its Falcon 9 rocket. This is the second Starlink mission to launch from Florida’s Space Coast since SpaceX completed its original orbital shell on Starlink L28 in May. The name, Starlink 4-3, stands for it being the third launch of the fourth orbital shell of satellites. Although 4-2 hasn’t launched yet, the names are set up well before the launch takes place. This shell will contain 336 satellites at an orbit of 560 km.

Alongside the Starlink satellites will be two BlackSky satellites. We’ve seen plenty of these Earth-observing satellites launch on Rocket Lab’s Electron.

Launch Date: Wednesday, December 2, 6:12 p.m. EST
