HUNTSVILLE, Ala. -- A sub-scale solid rocket motor that mimics NASA's Space Launch System booster design successfully was tested Wednesday at NASA's Marshall Space Flight Center. The 20-second firing tested new insulation materials on the 24-inch-diameter, 109-inch-long motor. The motor is a scaled down, low-cost replica of the solid rocket motors that will boost SLS off the launch pad. ATK of Brigham City, Utah, is the prime contractor for the booster. (Source:
