Stock Photo - Using mock-up components, technicians at the U.S. Army's White Sands Missile Range in New Mexico practiced the stacking process that will one day be involved in mating the Orion Pad Abort-1 flight test launch abort system and crew module hardware. The crew module was integrated with the PA-1 test separation ring and launch stand. The launch abort system, crew module and separation ring were developed at Langley Research Center, Hampton, Va. The launch stand and pad were developed at Dryden, where crew module systems were integrated. Dryden is leading the launch abort flight tests effort for the Orion Project Office, managed at the Johnson Space Center, Houston.
