SpaceX is shooting for new heights with its upcoming Starship test flight, and the booster tapped for the mission is in its final stretch of preparations before the mission.

The Super Heavy booster for Flight Test 15, Booster 22, underwent a static test fire on Sunday (Oct. 25), igniting all of its Raptor 3 engines for about 15 seconds. "Full duration 33-engine static fire for the Super Heavy booster preparing for Flight 15," SpaceX said in a post on X .

The test is a beginning of final checks on the first-stage vehicle, which will be mated with the Flight 15 upper stage, Ship 42, ahead of launch, but not before the spacecraft completes some tests of its own.

Ship 42 will also complete a series of tests as the next Starship launch approaches, including a static engine fire and final systems checks.…
