Facepalm: SpaceX was preparing its Starship rocket for a 10th flight test – initially scheduled for June 29 – when it exploded during a static fire at the Starbase launch site in Texas shortly after 11 pm MT on Wednesday. The launch timeline is now unclear following the incident.

A video shared by NASA Spaceflight shows a powerful explosion lighting up the Texas night sky during what was supposed to be a routine engine test. Cameron County officials confirmed the incident and said no one was injured. Local law enforcement has launched a formal investigation to determine the cause.

In a post on X, SpaceX said it was preparing the rocket for its tenth test flight when it experienced "a major anomaly" while fixed to the launch arm. The company didn't disclose the nature of the issue but confirmed that all personnel at the base were safe and accounted for.

SpaceX added that there's no immediate threat to nearby residents but advised people to avoid Starbase while cleanup operations are underway. Officials are closely monitoring air quality and safety in the surrounding area to ensure no hazards arise. Cleanup crews are working to secure the site and assess any environmental impact caused by the explosion.

In the last few hours, Elon Musk weighed in on the incident with a series of posts on X. He initially dismissed the explosion as "just a scratch" but later explained that preliminary investigations showed "a nitrogen COPV in the payload bay failed below its proof pressure," causing the catastrophic failure.

Starship has previously caught fire during routine testing. Last month, it exploded during its ninth test flight, following similar failures in January and March. These repeated setbacks highlight the ongoing challenges SpaceX faces in perfecting the rocket's design. Since April 2023, Starship has launched nine times – four successes and five failures.
