J-2X tests on A-1 end

STENNIS SPACE CENTER, Miss. – A series of hotfire tests on the next generation J-2X rocket engine came to an end Thursday. The gimbal test of the Rocketdyne J-2X No. 10002 was a 330-second test fire on the A-1 test stand. Now NASA has its sights on testing the Rocketdyne RS-25. Both engines will be used with NASA's Space Launch System. The J-2X will be used on the upper stage and the RS-25 on the core stage. (Source: NASA/SSC, 09/05/13) Previous
