SpaceX Starship Explosion Halts Deluge Test at Starbase

SpaceX starship testing at Starbase in Texas stopped on Sunday after an apparent explosion hit the deluge system during a launch-pad test. The test was aborted, leaving the water-deluge hardware that protects the pad during launch back in the spotlight.

NASA Spaceflight.com wrote, “During a deluge test today, what seems to be an explosive event was observed in the deluge farm followed by the deluge shutting down,” in an X post. That account also operates a live cam at Starbase in Boca Chica on the Gulf of Mexico, and the 18-second video circulating from the scene showed debris flying hundreds of metres into the air.

The deluge system is part of the launch infrastructure SpaceX uses to absorb heat and energy from a rocket during launch. SpaceX says about 1.3 million liters of water are pumped at high pressure through the Ground Support Equipment, which is a steel plate under the launch pad with holes. The water evaporates from the engine heat.

Ground Support Equipment issues

SpaceX has also said in documentation titled “Test Like You Fly” that it has recently had problems with the Ground Support Equipment of the water deluge system. The hardware was installed after the launch pad was severely damaged during the first launch of Starship in April 2023.

That history matters because the deluge system sits at the center of the pad work supporting the next version of the vehicle. SpaceX announced Starship V3 after the eleventh flight of Starship last October, and the first launch of Starship V3 is currently scheduled for May 12.

The Sunday abort leaves the launch-pad system under pressure just weeks before that date. The open question is whether SpaceX can finish the deluge-side fixes in time for May 12, because the pad hardware is not a side issue here; it is part of the launch sequence itself.
