Past Tuesday, on March 30, SpaceX launched its most recent Starship prototype, SN11, amid the significant morning fog in Boca Chica, Texas. It was SpaceX’s fourth higher-altitude take a look at with Starship. SN11 successfully soared to the specified altitude of 6.2 miles (10 kilometers). But shortly right after its engines fired up for its descent, the rocket exploded in mid-air.
No one was seriously sure what happened at the minute due to the dense fog at the check web-site. Footage of the launch pad showed SN11 was nowhere in sight immediately after the rocket’s descent. SpaceX later on verified that SN11 “experienced a speedy unscheduled disassembly,” or RUD. And it was not until finally this early morning that its CEO Elon Musk uncovered what brought on the explosion.
“A (fairly) modest CH4 [methane] leak led to fire on engine 2 and fried part of avionics, causing difficult get started trying landing burn up in CH4 turbopump,” Musk tweeted Monday morning in response to the Twitter account Everything SpaceX inquiring for updates on SN11’s RUD investigation.
All Starship prototypes by much are driven by a few Raptor engines loaded with tremendous chilly methane and oxygen propellants. These engines are dependable for pushing the rocket all the way to 10 kilometers in the sky. The rocket is programmed to shut down every single of the engines in sequence once achieving the ideal altitude, pitch to a horizontal place and begin a controlled descent again to the floor. The engines are meant to reignite once again in the very last stage of descent to flip the rocket 90 degree for a vertical landing.
For the duration of the SN11 check, the ascent period, transition to horizontal and management all through its absolutely free-fall back again to Earth all went in accordance to the system, Musk said. But a tiny methane leak led to a hearth on one particular of the Raptor engines, resulting in a “hard start” in the engine’s methane turbopump at the starting of the landing burn up.
Ascent phase, transition to horizontal & command throughout absolutely free drop had been fantastic.
A (somewhat) compact CH4 leak led to fireplace on engine 2 & fried portion of avionics, creating hard start out trying landing burn off in CH4 turbopump.
This is getting fastened 6 strategies to Sunday.

Starship is SpaceX’s future-era rocket tasked to swap the latest Falcon 9-Dragon method for cargo and crew missions to Earth’s orbit. The vehicle will also type the upper phase of the giant booster that will transportation astronauts to the moon and Mars.
SpaceX is chaotic developing new iterations of the Starship. For each NASA Spaceflight, SpaceX has 4 prototypes waiting for significant-altitude exams. Its most recent 1, SN15, in final preparations for a rollout at the Boca Chica exam internet site.
