Orion Launch Abort System

NASA, Alliant Techsystems (ATK) and Lockheed Martin performed a ground test of a full-scale attitude control motor for the launch abort system of the Orion crew exploration vehicle. The test was conducted at ATK's facility in Elkton, Md.

The motor operates to keep the crew module on a controlled flight path in the event it needs to jettison and steer away from the Ares I launch vehicle in an emergency, and then it reorients the module for parachute deployment and landing. Together, the eight-proportional valves can exert up to 7,000 pounds of steering force to the vehicle in any direction upon command from the crew module.
