ATK announced that, together with NASA and industry partners Lockheed Martin Corporation and Orbital Sciences Corporation, it had successfully performed a ground-test firing of the attitude-control motor-thruster system of the launch-abort system (LAS) for NASA’s Orion crew exploration vehicle (CEV). The test, conducted at ATK’s facility in Elkton, Maryland, marked a milestone in the development of the Orion spacecraft. The fifth in a series of ground tests of the craft’s attitude-control motor system, the High Thrust-8 (HT-8) demonstration provided validation that several flight-weight subsystems were performing as designed. According to a contract with Orbital Sciences Corporation, ATK was responsible for the design of the attitudecontrol motor, which would provide steering for the LAS in the event of a catastrophic failure on the launchpad or during Orion’s initial ascent. Orbital Sciences Corporation was responsible for delivering the LAS motors for Lockheed Martin, the prime contractor for NASA’s Orion Project.
