Presented by collectSPACE.com -- The Source for Space History and Artifacts. NASA and ATK Aerospace Systems successfully completed on Tuesday, Aug. 31, 2010, a two-minute, full-scale test of the largest and most powerful solid rocket motor designed for flight. The motor is potentially transferable to future heavy-lift launch vehicle designs. The stationary firing of the first-stage development solid rocket motor, dubbed DM-2, was the most heavily instrumented solid rocket motor test in NASA history. More than 760 instruments measured 53 test objectives. VIdeo credit NASA TV
