With a loud roar and mighty column of flame, NASA and ATK Aerospace Systems successfully completed 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 conducted by ATK, a division of Alliant Techsystems of Brigham City, Utah. DM-2 is the most heavily instrumented solid rocket motor in NASA history, with a total of 53 test objectives measured through more than 760 instruments.
Prior to the static test, the solid rocket motor was cooled to 40 degrees Fahrenheit to verify the performance of new materials and assess motor performance at low temperatures during the full-duration test. Initial test data showed the motor performance met all expectations.
