SpaceX had to swap out the first stage booster used during the previous attempt and replace it with another for this mission. Liftoff from pad 40 happened at 12 a.m. EST (0500 UTC) on Sunday, Dec. 29.
The mission, dubbed ‘Astranis: From One to Many,’ includes the company’s new UtilitySat, which is designed to relocate within geostationary Earth orbit over its life to respond to different mission objectives.
