Final Planned Space Shuttle Main Engine Test – July 29

NASA’s John C. Stennis Space Center will be conducting the final planned space shuttle main engine test at 2 p.m. CDT on Wednesday, July 29,2009.

The 520-second test ends a 34-year era of space shuttle main engine testing at the facility. Stennis engineers conducted their first space shuttle main engine test in 1975. The first shuttle mission was launched in 1981. Since then, 126 missions have flown, all with main engines tested by Stennis. Seven flights remain before the space shuttle fleet is retired.

The primary work at Stennis has been space shuttle main engine testing, but the center also is helping NASA prepare for the next era of human spaceflight. Between 2007 and 2008, Stennis conducted component testing as part of early development of the J-2X engine for NASA’s Constellation Program. The J-2X will be tested at simulated altitudes up to 100,000 feet on the 300-foot A-3 test stand currently under construction at the center.
