SpaceX fired up its SN20 Starship prototype in earnest for the primary time Thursday night time (Oct. 21), notching an enormous milestone on the automobile’s deliberate path to orbit.
The 165-foot-tall (50 meters) SN20, which is presently outfitted with two Raptor engines, carried out a quick “static fire” check at 8:16 p.m. EDT Thursday (0016 Oct. 22 GMT) at SpaceX’s Starbase facility, close to the South Texas city of Boca Chica.
The check appeared to contain simply one of many two Raptors, as identified by commentators with NASASpaceflight.com, which livestreamed the occasion. One of SN20’s engines is a typical “sea-level” Raptor, whereas the opposite is a “vacuum” model, which is optimized to function in space.

About half an hour after the check, SpaceX confirmed via Twitter that the vacuum Raptor had fired up. It was the primary such trial of a vacuum Raptor built-in on a Starship automobile, in line with the corporate.
Then, at 9:18 p.m. EDT (0118 GMT) on Thursday, SN20 performed a second static fireplace. This one seemed a bit brighter and extra highly effective than the primary and should have concerned each Raptors, as a NASASpaceflight.com commentator famous.

SpaceX is creating Starship to take individuals and cargo to the moon, Mars and different distant locations. NASA has already signed on, choosing Starship as the primary crewed lunar touchdown system for its Artemis moon program.
Starship consists of two parts: a spacecraft referred to as Starship and a large first-stage booster generally known as Super Heavy. Both will probably be totally reusable, and each will probably be powered by Raptors — six for the ultimate Starship and 29 for Super Heavy.
SN20 will ultimately sport six Raptors — three customary and three vacuum. SpaceX is prepping the automobile for an orbital flight check within the coming months, a primary for the Starship program. Starship prototypes have launched before, however these had been three-engine (at most) automobiles that reached a most altitude of about 6 miles (10 kilometers).
SN20 and a Super Heavy generally known as Booster 4 will launch from Starbase. The booster will make an ocean splashdown within the Gulf of Mexico, about 20 miles (32 km) from the launch website. But SN20 will go all the best way to orbit, if all goes in line with plan, and ultimately splash down off the Hawaiian island of Kauai.
SpaceX goals to launch that landmark check flight comparatively quickly, however the timeline will not be completely within the firm’s management. The U.S. Federal Aviation Administration (FAA) is conducting an environmental evaluation of Starship’s orbital launch website. The FAA lately launched a draft of that evaluation, however extra work must be carried out; the company will settle for public feedback on the draft till Nov. 1, then incorporate these feedback into the ultimate report.
While as we speak marked SN20’s debut static fires, the automobile has breathed flame earlier than. On Monday (Oct. 18), SpaceX performed a brief test of the vehicle’s preburners, which warmth and blend the Raptor engines’ liquid methane and liquid oxygen propellants.
