Orion approaching the International Space Station

The spacecraft that NASA hopes will return humans to the moon is scheduled to begin flight testing in fall 2008. The Orion spacecraft's first duty will be to replace NASA's aged space shuttle fleet with missions in Earth's orbit, including visits to the International Space Station. They are scheduled to begin in 2015.
