Commerical Crew Program (CCP) Astronauts visit Aerojet Rocketdyn

NASA Commercial Crew astronaut Eric Boe listens as Jim Moss, site director for Aerojet Rocketdyne's West Palm Beach facility, discusses aspects of the RL10 engine as it stands in a vacuum chamber at Aerojet Rocketdyne's test stand in West Palm Beach, Florida. The engine will be one of two used for the Centaur upper stage during a United Launch Alliance Atlas V mission to launch Boeing's CST-100 Starliner on a flight test carrying a crew. The engine was test-fired as part of acceptance testing to confirm the engine is ready for flight.
