NASA JSC Memo: Commercial-Crew Vehicle Transition Concepts 1 March 2010

"The President's 201 1 Budget Proposal which was unveiled on February 8, 2010, places an emphasis on commercial vehicles "to provide astronaut transportation to the International Space Station (ISS), reducing the sole reliance on foreign crew transports and catalyzing new businesses and significant new jobs." The following paper provides recommendations for the transition to a commercial-crew vehicle to the ISS which leverages the experience gained in the operation of the Space Shuttle, the ISS, and in the design of Constellation."
