NASA conducted its final J-2X rocket engine test of the year Dec. 14, the 10th firing in a series of tests on the new upper-stage engine that will carry humans farther into space than ever before. The J-2X engine was test fired on the A-2 Test Stand at NASA's Stennis Space Center, in south Mississippi. The main focus of this test was to characterize engine performance calibration and the effects of fuel inlet pressure variations. The results of this test are being analyzed. (NASA/SSC)
I have one of these engines in my van, good gas mileage!
