SpaceX determines cause of Starship SN11 prototype crash

在一个 鸣叫 在星期一, the billionaire replied to a SpaceX-themed Twitter account that asked how the investigation into SN11’srapid unscheduled disassembly” — or RUDwas going.

Ascent phase, transition to horizontal & control during free fall were good. 一个 (relatively) small CH4 leak led to fire on engine 2 & fried part of avionics, causing hard start attempting landing burn in CH4 turbopump,” 他解释.

一个 “hard startis when there’s ignition with too much fuel in the engine’s combustion chamber and pressure is too high, according to Space.com.

This is getting fixed 6 ways to Sunday,” Musk said.

The failed test flight launched last March 30 from SpaceX’s South 德州 Starship development center near Boca Chica Village.

After ascending to a maximum altitude of 6.2 英里, as planned, the 165-foot-tall stainless steel spacecraft broke apart right before touchdown.

Dense fog obscured live video of the explosion and onboard cameras froze after the SN11 made its signature flip maneuver in preparation for landing.

CNET reported on Monday that other cameras directed at the landing pad had captured an orange glow and a storm of debris as it rained down on the exclusion zone around the pad.

At least the crater is in the right place!” Musk tweeted 在三月 30.

SpaceX later confirmed that SN11 had “有经验的” a RUD, marking the fourth Starship vehicle in a row SpaceX has lost since December.

The CH4, or methane, powers the SN11’s three Raptor engines, giving it more than 1 million pounds of thrust.

The Raptors were supposed to shut down once reaching the desired altitude and reignite in the last stage of the rocket’s descent for a vertical landing.

Both SpaceX’s Starship and Super Heavythe booster stagewill be powered by Raptor engines and the company has already built the next updated Starship prototype, SN15.

The Starship is designed for orbital flight and will take both human passengers and cargo to the 月亮 and eventually to Mars.
