![]() "We've seen them manufacture what was called Raptor 1.0. "SpaceX has moved very quickly on development," Kirasich said about Raptor. If the engines fail, the astronauts will probably die. For a successful lunar mission, these engines will need to re-light successfully on the surface of the Moon to carry astronauts back to orbit inside Starship. Thirty-three of these Raptor 2 engines power the Super Heavy booster that serves as the vehicle's first stage, and six more are used by the Starship upper stage. The Raptor rocket engine is crucial to Starship's success. During a subcommittee meeting of NASA's Advisory Council on Monday, however, Kirasich said SpaceX has made substantial progress in both areas. Two of NASA's biggest technological development concerns were the new Raptor rocket engine and the transfer and storage of liquid oxygen and methane propellant in orbit, said Mark Kirasich, NASA's deputy associate administrator who oversees the development of Artemis missions to the Moon. However, because of the company's self-investment of billions of dollars into the project, SpaceX submitted the lowest bid, and from its previous work with SpaceX, NASA had confidence that the company would ultimately deliver. In some ways, this was the riskiest choice of NASA's options because Starship is a very large and technically advanced vehicle. NASA selected SpaceX and Starship for its Human Landing System in April 2021. Elon Musk/Twitter reader comments 398 withĪ senior NASA official said this week that SpaceX has done "very well" in working toward the development of a vehicle to land humans on the surface of the Moon, taking steps to address two of the space agency's biggest concerns.
