J-2X Engine 10001 at Stennis Space Center

J-2X engine 10001 is returning back to the A-2 Test Stand at NASA's Stennis Space Center for its second round of tests. The developmental engine underwent an initial series of tests last year. Both the engine and test stand have been modified to begin simulated altitude testing in the coming months.

The J-2X engine is designed and built by Pratt & Whitney Rocketdyne for NASA's Marshall Space Flight Center. It is the first human-rated liquid oxygen and liquid hydrogen rocket engine to be developed in 40 years. The J-2X will provide upper-stage power for NASA's Space Launch System, a new heavy-lift vehicle capable of missions beyond low-Earth orbit.
