Being developed by NASA in partnership with Pratt & Whitney Rocketdyne, the J-2X is based on a proven design that could provide a safe and reliable solution for NASA's future heavy-lift launch vehicles that will carry humans beyond low-Earth orbit to deep space.
The seven-second test firing of J-2X development engine E10001 was conducted July 26, 2011, at NASA's John C. Stennis Space Center.
Fueled by liquid hydrogen and liquid oxygen, the next-generation J-2X engine will generate 294,000 pounds of thrust.
