SpaceX Tests 33-Engine Super Heavy Booster for Starship Flight 15

SpaceX conducted a full-duration static-fire test of a Super Heavy booster at Starbase, Texas, on October 25, 2026. SpaceX described the test as involving all 33 Raptor engines. Observers identified the booster as Booster 22 on Pad 2.

Key details

• The booster remained secured to the launch mount during the static fire.
• NASA Artemis program manager Jeremy Parsons said both Flight 15 vehicles had completed cryogenic proof testing.
• Parsons described November as a probable timeframe for Flight 15.
• Parsons said the mission might attempt to return both vehicles to the launch site for catches.

The static-fire test ran all 33 Raptor engines on Super Heavy Booster 22.

Why it matters

The test exercised the Super Heavy booster’s full set of 33 Raptor engines ahead of the next Starship flight. Parsons’ comments also connect the booster test with preparations for both Flight 15 vehicles.
