[SLS] J-2X Engine Test Fire (09/11/11)

A J-2X Engine was tested at Stennis Space Center today, 9th November 2011 just after 9pm UTC.

The engine is a key component of NASA's Space Launch System, which will carry the Orion spacecraft, its crew, cargo, equipment and science experiments beyond Earth orbit.

Pratt and Whitney Rocketdyne is developing the J-2X engine for NASA's Marshall Space Flight Center in Huntsville, Ala. The SLS rocket engines will use a liquid hydrogen and liquid oxygen propulsion system, which will include the J-2X engine for the upper stage and RS-25D/E engines (space shuttle main engines) for the core stage.
