Stennis Holds Last Planned Space Shuttle Engine Test
Steam billows from the A-2 Test Stand at NASA's John C. Stennis Space Center during a July 29 space shuttle main engine test. The test was the last planned test for the Space Shuttle Program, which is set to end next year. Stennis engineers conducted their first test of a space shuttle main engine in 1975 and have tested every engine used in the program since that time. During those 34 years and almost 130 shuttle flights, no mission has failed due to engine malfunction.
