SpaceX final week efficiently landed its reusable Starship rocket after finishing a high-altitude flight take a look at, but then it exploded. Now we all know a little bit bit extra about why it occurred.
Like siblings SN8 and SN9 that got here earlier than, this model was powered by three engines, every shutting down in sequence previous to reaching apogee—about six miles in altitude. The automobile carried out as anticipated, reorienting itself for reentry and descending right into a exact touchdown on the meant location.
“Starship SN10 landed in a single piece,” SpaceX CEO Elon Musk tweeted on the time, nearly keen one thing to go fallacious. Ten minutes later, one thing did. Varied studies suggested an enormous fireplace on the automobile’s base despatched it on an impromptu second journey into the sky.
In a Tuesday tweet—responding to images that seem to point out workers testing the touchdown legs of Starship SN11 forward of its upcoming flight take a look at—Musk revealed that SN10’s engine “was low on thrust due (most likely) to partial helium ingestion from gas header tank.”
SN10 engine was low on thrust due (most likely) to partial helium ingestion from gas header tank. Affect of 10m/s crushed legs & a part of skirt. A number of fixes in work for SN11.

He additionally confirmed that the helium ingestion was doubtless the results of a pressurization system, added to the CH4 header tank to right for a earlier error within the SN8 mannequin. “My fault for approving,” Musk wrote. “Sounded good on the time.”
That is the issue with touchdown on a tough floor like SpaceX’s Boca Chica launch website. “Might simply have it land on an enormous internet or bouncy fortress,” Musk proposed in a subsequent put up. “Lacks dignity, however would work.” There are “a number of fixes” within the works for Starship SN11, which just lately rolled out to the Texas launch website and may very well be able to take off as soon as next week.
The Federal Aviation Administration (FAA) final month concluded investigations right into a pair of SpaceX Starship trials, together with the botched touchdowns of two high-altitude take a look at flights. In early December, SpaceX efficiently launched its Starship rocket—which crash landed again on Earth. Two months later, the agency despatched the SN9 hovering miles above the corporate’s Texas amenities, finishing one other profitable flight demonstration—which, as soon as once more, resulted in a fiery explosion of prototype items.
