Musk wrote that the nitrogen COPV appears to have failed below its proof pressure, within conditions that should not have damaged the tank. “If further investigation confirms that this is what happened, it is the first time ever for this design,” Musk added.
Picking Up the Pieces
Earlier Wednesday, just hours before the late-night explosion at Starbase, an advisory released by the Federal Aviation Administration showed SpaceX had set June 29 as a tentative launch date for the next Starship test flight. That won’t happen now, and it’s anyone’s guess when SpaceX will have another Starship ready to fly.
Massey’s Test Site, named for a gun range that once occupied the property, is situated on a bend in the Rio Grande River, just a few hundred feet from the Mexican border. The test site is currently the only place where SpaceX can put Starships through proof testing and static fire tests before declaring the rockets are ready to fly.
The extent of the damage to ground equipment at Massey’s was not immediately clear, so it’s too soon to say how long the test site will be out of commission. For now, though, the explosion leaves SpaceX without a facility to support preflight testing on Starships.
The videos embedded below come from NASASpaceflight.com and LabPadre, showing multiple angles of the Starship blast.
The explosion at Massey’s is a reminder of SpaceX’s rocky path to get Starship to this point in its development. In 2020 and 2021, SpaceX lost several Starship prototypes to problems during ground and flight testing. The visual of Ship 36 going up in flames harkens back to those previous explosions, along with the fiery demise of a Falcon 9 rocket on its launch pad in 2016 under circumstances similar to Wednesday night’s incident.
SpaceX has now launched nine full-scale Starship rockets since April 2023, and before the explosion, the company hoped to launch the 10th test flight later this month. Starship’s track record has been dreadful so far this year, with the rocket’s three most recent test flights ending prematurely. These setbacks followed a triumphant 2024, when SpaceX made clear progress on each successive Starship suborbital test flight, culminating in the first catch of the rocket’s massive Super Heavy booster with giant robotic arms on the launch pad tower.
Stacked together, the Super Heavy booster stage and Starship upper stage stand more than 400 feet tall, creating the largest rocket ever built. SpaceX has already flown a reused Super Heavy booster, and the company has designed Starship itself to be recoverable and reusable, too.
After last year’s accomplishments, SpaceX appeared to be on track for a full orbital flight, an attempt to catch and recover Starship itself, and an important in-space refueling demonstration in 2025. The refueling demo has officially slipped into 2026, and it’s questionable whether SpaceX will make enough progress in the coming months to attempt recovery of a ship before the end of this year.
Ambition Meets Reality
SpaceX debuted an upgraded Starship design, called Version 2 or Block 2, on a test flight in January. It’s been one setback after another since then.
The new Starship design is slightly taller than the version of Starship that SpaceX flew in 2023 and 2024. It has an improved heat shield to better withstand the extreme heat of atmospheric reentry. SpaceX also installed a new fuel feed line system to route methane fuel to the ship’s Raptor engines, and an improved propulsion avionics module controlling the vehicle’s valves and reading sensors.
