DM-2, Test Fire of 5 Segment Solid Rocket Booster

NASA’s next-generation, five-segment solid rocket development motor — or DM-2 — was successfully fired in its test stand at ATK in Promontory, Utah. Prior to the firing, which lasted just more than two minutes, the motor’s overall temperature was lowered to 40 degrees Fahrenheit to validate the motor’s ability to perform properly in cold weather.
