AmericaSpace Note: It was announced today that the MPCV will be based on the Orion spacecraft. Here is a timeline of the Orion program published by NASA.
Currently, Orion is the only new spacecraft being built that has had a successful human rating certification preliminary design review (PDR). Word is that MPCV’s critical design review (CDR), which will finalize the design of the spacecraft, will come within the next couple of months. When Orion is completed in early 2013, it will be the first new human rated spacecraft since the Space Shuttle, the vehicle that it is replacing.
