Launch Abort System Jettison Motor

The Orion Launch Abort System (LAS) consists of three solid rocket motors: the abort motor that pulls the crew module away from the launch vehicle; the attitude control motor that is used for steering to reorient the crew module’s position following an abort; and Aerojet Rocketdyne’s jettison motor that separates the launch abort system from the crew module so that parachutes can be deployed for a safe landing. The jettison motor is the only motor that will be activated on all nominal missions to separate the spacecraft from the LAS assembly shortly after the activation of the launch vehicle’s second stage.
