Orbital ATK successfully tested an SR 118 rocket motor at the company’s Promontory, Utah, facility on March 29. This ground test lit up with smoke and fire as the motor ignited to test its capabilities. NASA and Lockheed Martin are planning to use an SR 118 rocket motor to launch the Orion spacecraft to test its Launch Abort System, prior to launching a crewed Orion aboard NASA’s Space Launch System. This Ascent Abort 2 Flight Test, AA-2, is planned for April of 2019. Credit: orbital_atk #NASA #orbitalatk #AA2 #orion #SLS #engineering #rocket #smokeandfire
