Now that an Orion jettison motor has performed as planned in the third ground test of the motors, Aerojet Rocketdyne plans to start work on six more, including one NASA intends to install atop a Space Launch System rocket for Orion's first astronaut flight. Each jettison motor will be a critical component of the Launch Abort System, a stack of motors and an aeroshell that would whisk a crew away from an exploding or fizzing SLS launch vehicle. In an emergency, the abort motor would jolt the Orion crew capsule and its aeroshell off the failing SLS. An attitude control motor would then steer the assembly toward a gentle parachute landing once the jettison motor separates the crew capsule from the aeroshell.
