Abort engine hot-fired

CANOGA PARK, Calif. -- Pratt and Whitney Rocketdyne completed mission-duration hot-fire tests on a launch abort engine on Friday, March 9. The engine is in support of Boeing's CST-100 spacecraft being developed for NASA's Commercial Crew Development Round 2. Boeing's Crew Space Transportation system is a reusable, capsule-shaped spacecraft designed to take up to seven people or a combination of people and cargo to low Earth orbit, including the International Space Station. The abort propulsion system is designed to push the crew capsule to safety if an abort becomes necessary during launch or ascent. (Source: PRNewswire, 03/13/12) The CST-100 is compatible with the Atlas V, Delta IV and Falcon 9 launch vehicles. Gulf Coast note: NASA's Stennis Space Center, Miss., tests RS-68 engines for United Launch Alliance's Delta IV, and also has a Pratt and Whitney Rocketdyne operation.
