SpaceX thinks it knows why Starship exploded on its last test flight
Briefly

On January 16, 2025, SpaceX's seventh test flight of its Starship spacecraft ended in explosion due to fires in the aft section, leading to engine shutdowns and loss of communication. Despite a successful launch and booster recovery, Starship encountered issues after separation, with detected pressure rises and flash events indicating propellant leaks. The situation escalated, causing the spacecraft's safety system to self-destruct three minutes after losing contact. SpaceX attributed the explosion to unexpectedly strong vibrations affecting the propulsion system, surpassing the tested limits and causing a hazardous leak.
SpaceX believes the explosion during the seventh test flight of its Starship spacecraft resulted from aft section fires causing multiple engine shutdowns and loss of communication.
Fires in the attic section of Starship led to a self-destruct sequence activated by its Autonomous Flight Safety System after losing contact with the spacecraft.
