Past Tuesday, on March 30, SpaceX introduced its newest Starship prototype, SN11, amid the weighty morning fog in Boca Chica, Texas. It was SpaceX’s fourth substantial-altitude exam with Starship. SN11 effectively soared to the specified altitude of 6.2 miles (10 kilometers). But shortly following its engines fired up for its descent, the rocket exploded in mid-air.

No a single was actually guaranteed what happened at the second thanks to the dense fog at the exam web page. Footage of the start pad confirmed SN11 was nowhere in sight soon after the rocket’s descent. SpaceX later verified that SN11 “experienced a swift unscheduled disassembly,” or RUD. And it was not until eventually this morning that its CEO Elon Musk disclosed what caused the explosion.

“A (reasonably) modest CH4 [methane] leak led to fireplace on motor 2 and fried part of avionics, producing hard begin making an attempt landing burn in CH4 turbopump,” Musk tweeted Monday morning in reaction to the Twitter account Anything SpaceX asking for updates on SN11’s RUD investigation.

All Starship prototypes by considerably are powered by three Raptor engines crammed with tremendous chilly methane and oxygen propellants. These engines are liable for pushing the rocket all the way to 10 kilometers in the sky. The rocket is programmed to shut down each of the engines in sequence after reaching the preferred altitude, pitch to a horizontal posture and begin a managed descent back to the ground. The engines are meant to reignite once more in the last stage of descent to flip the rocket 90 degree for a vertical landing.

Throughout the SN11 take a look at, the ascent stage, changeover to horizontal and handle for the duration of its free of charge-tumble again to Earth all went in accordance to the approach, Musk explained. But a small methane leak led to a fireplace on one of the Raptor engines, causing a “hard start” in the engine’s methane turbopump at the commencing of the landing burn up.

Starship is SpaceX’s subsequent-technology rocket tasked to substitute the latest Falcon 9-Dragon procedure for cargo and crew missions to Earth’s orbit. The automobile will also form the upper phase of the giant booster that will transport astronauts to the moon and Mars.

SpaceX is occupied setting up new iterations of the Starship. For each NASA Spaceflight, SpaceX has 4 prototypes ready for substantial-altitude exams. Its newest a single, SN15, in remaining preparations for a rollout at the Boca Chica examination web-site.
