Ignition of Development Motor-2: DM-2 is the largest and most powerful solid rocket motor designed for flight. It is the most heavily instrumented solid rocket motor in NASA history with a total of 53 test objectives measured through more than 760 instruments. DM-2 was chilled to 40 degrees Fahrenheit as the test was designed to assess performance at the lowest end of the temperature range. The Aug. 31 static test was conducted by ATK Aerospace Systems in Promontory, Utah. DM-2 is managed by the Ares Projects Office at NASA's Marshall Space Flight Center in Huntsville, Ala.
