Pad Abort 1 Test Successful
NASA successfully tested the Launch Abort System developed for the Orion crew exploration vehicle on May 6, 2010. The 97-second flight test, dubbed Pad Abort 1 test (PA1), was the first fully integrated test of the Launch Abort System developed for Orion. The test took place at the U.S. Army’s White Sands Missile Range near Las Cruces, N.M.

Orbital was a key member of the Lockheed Martin-led team that has been selected to build the Orion crew exploration vehicle (CEV). The LAS design, was using Orbital’s proven small rocket technology, is a key element in vastly improving the safety of the flight crew as compared to current human space systems.
Orbital was responsible for the design, development and build of the Launch Abort System (LAS) tower. The LAS components consist of the abort, jettison and attitude control motors, structures, ordnance and harnesses, and will provide escape capabilty for the Orion crew from pad operations through ascent.
Orbital managed the Orion LAS at its Dulles, VA campus and at the facilities of its propulsion subcontractors, Aerojet and Alliant Techsystems.
