NASA Engineers Complete Engine Test Series for Ares I Rocket
J2X workhorse gas generator test
Engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., completed a series of tests on a key component of the J-2X engine, which will propel the next-generation Ares I rocket on its journey to space. The test on Aug. 15 -- the last of 20 in this series -- concluded the second of four planned batteries of tests on the J-2X's workhorse gas generator, the driver for the turbopumps which start the engine. The third phase of testing will begin in July 2009. (Image credit: NASA)
