A significant setback occurred in the SpaceX Starship program on June 19. Ship 36, designated for the upcoming Flight 10, exploded during preparations for a static-fire test at Starbase, Texas. Video footage revealed the explosion originating near the vehicle's top, potentially indicating a header tank malfunction.
SpaceX confirmed the incident, stating, “On Wednesday, June 18 at approximately 11 p.m. CT, the Starship preparing for the tenth flight test experienced a major anomaly while on a test stand at Starbase,” adding that all personnel were safe. The company is currently investigating the cause of the explosion and cooperating with local officials to secure the test site.
This explosion adds to a series of challenges faced by SpaceX's Starship development. Flight 7 experienced propulsion system failures due to unexpected harmonic resonance. Flight 8 failed due to a Raptor engine malfunction. While Flight 9 successfully completed ascent, it suffered a propellant leak resulting in an uncontrolled reentry. This latest incident raises serious concerns about the program's trajectory.
The planned June 29 launch of Flight 10, previously indicated by the Federal Aviation Administration, is now uncertain. The explosion marks a significant regression, reminiscent of issues encountered years ago, according to one industry official at the Paris Air Show.
The explosion occurred before engine ignition. A cloud of condensation visible just prior to the blast suggests a possible tank failure as the likely cause. This latest setback underlines the complexities and challenges inherent in developing such advanced launch vehicles. SpaceX's investigation will be critical in determining the exact cause and implementing necessary improvements to prevent similar incidents in the future.
