"Engineers testing the parachute system for NASA's Orion spacecraft increased the complexity of their tests Thursday, Jan. 16, adding the jettison of hardware designed to keep the capsule safe during flight. The test was the first to give engineers in-air data on the performance of the system that jettisons Orion's forward bay cover. The cover is a shell that fits over Orion's crew module to protect the spacecraft during launch, orbital flight and re-entry into Earth's atmosphere. When Orion returns from space, the cover must come off before the spacecraft's parachutes can deploy. It must be jettisoned high above the ground in order for the parachutes to unfurl."
"Engineers and safety specialists from NASA and Space Exploration Technologies (SpaceX) gathered in Morro Bay, Calif., in late December to demonstrate how the company's Dragon spacecraft's parachute system would function in the event of an emergency on the launch pad or during ascent. The test was part of an optional milestone under NASA's Commercial Crew Integrated Capability (CCiCap) initiative and approved by the agency in August."
