ATK completes SLS test

NASA and ATK completed the second in a series of development tests for NASA's Space Launch System booster program late last month at ATK's Promontory, Utah, facility. The avionics and controls test, Flight Control Test 2, included a hot fire of the fully integrated heritage thrust vector control, the new SLS booster avionics subsystem and new electronic support equipment. FCT-2 focused on replacement of heritage test equipment with new electronic support equipment. Much of the equipment replaced was designed and built during the mid- to late-1970s and was successfully used on all Space Shuttle reusable solid rocket motor (RSRM) and five segment RSRM static motor firings.
