The failure of SpaceX’s Starship on its most recent test flight had a different root cause than the previous failure, SpaceX said May 23.

This next flight marks a critical moment for SpaceX as the Elon Musk-led company attempts to get its Starship program back on track.

Previously failed test flights resulted in Starship debris raining down over Turks and Caicos and parts of the Bahamas. Although SpaceX has said the debris has been limited to pre-planned Debris Response Areas, on multiple occasions the FAA has briefly slowed and diverted flights, and initiated full ground stops at several Florida airports.
