WASHINGTON -- NASA has reached an important milestone for the next U.S. transportation system that will carry humans into deep space. NASA Administrator Charles Bolden announced today that the system will be based on designs originally planned for the Orion Crew Exploration Vehicle. Those plans now will be used to develop a new spacecraft known as the Multi-Purpose Crew Vehicle (MPCV).

加圧スペースが690立方フィート（≒20立方メートル）、居住区画が316立方フィート（≒９立方メートル）。アポロの居住区画が大雑把に6立方メートルくらいだから、その1.5倍くらいの広さになる。
