SpaceX has shared dramatic slow-motion footage displaying a Raptor engine powering down on the finish of a latest take a look at hearth.
“Shutdown of a Raptor vacuum engine in sluggish movement,” SpaceX stated in a message accompanying the video (under), including that the engine’s nozzle “is sized to be used by Starship within the Earth’s higher ambiance and outer house, so operation at sea degree and low chamber pressures leads to movement separation creating seen rings within the exhaust.”

SpaceX doesn’t say by how a lot the footage has been slowed, however the element seen within the exhaust means that it’s enjoying at approach under the actual velocity.
As SpaceX talked about, the Raptor engines energy the Starship spacecraft, which is at present below growth. The Starship spacecraft has six engines — three Raptor engines for touchdown on Earth or one other planet, and three Raptor Vacuum (RVac) engines to be used within the vacuum of house, certainly one of which options within the video.
The Tremendous Heavy rocket, which carries the spacecraft to orbit, is powered by 33 Raptor engines that collectively create a colossal — and record-breaking — 17 thousands and thousands kilos of thrust at launch. The engines themselves are powered by cryogenic liquid methane and liquid oxygen. You’ll be able to see the Raptors in motion through the Tremendous Heavy’s second take a look at launch, which happened in December forward of its most up-to-date flight in March.
The Raptor engines are extra highly effective than the Merlin engines utilized by SpaceX’s workhorse Falcon 9 rocket. The elevated energy is required for the form of missions that SpaceX needs to make use of the Tremendous Heavy and Starship for as soon as the testing part is full. These embody transporting cargo and crew to the moon as a part of NASA’s Artemis program, and will even contain extra formidable missions corresponding to the primary crewed flight to Mars, which may happen within the 2030s.
