I thought this week I ought to describe to you the new engine which will be used for human travel in space. The J-2X engine is a variation of the J-2T engine, which was a variation of the J-2S engine. NASA began construction of the engine in 2007 at the Stennis Space Center. Nine test of the heritage J-2 engine components were conducted in preparation for the design of the J-2X engine. The J-2X was chosen for the Project Constellation manned lunar landing program. Though the project was cancelled by the President, development of the J-2X has continued for its potential as the second stage engine for the heavy-lift Space Launch System.
