Following a test campaign focused on SpaceX’s Starship vehicle, the Super Heavy booster is now taking up the mantle of testing at the Starbase launch site. Booster 3 rolled out of the High Bay on Thursday, taking the trip down Highway 4 before being placed on suborbital Pad A’s modified mount for a series of ground testing objectives.
The tests will pave the way for Booster 4, already in the opening stages of pre-stacking, which will be hosted at the under-construction Orbital Launch Site (OLS) with Starship 20 for a full-stack ride into space later this year.
