Crew Return Vehicle

A Crew Return Vehicle and Crew Rescue Vehicle ( CRV) is a spacecraft which is docked to the International Space Station (ISS ). It is used to safely return the crew in the event of a severe accident to Earth. Currently, two Soyuz spaceships serve as a CRV because the crew was increased to six.

There is the space agencies involved in the construction of the ISS, a variety of studies for the realization of spaceships that would be conceivable as CRV:

In these missions, Orion had also served as an emergency vehicle. In February 2010, the Constellation program, which included the Orion spacecraft, was hired primarily because of the damning report of the Augustine Commission and arrears due to the multi-year schedule. The building on the development of the Orion spacecraft new manned U.S. space ship MPCV is only at the expected end of the ISS operating time (~ 2020) to be ready for use and is probably no longer relevant for crew transport to and from the ISS, and thus also not serve as a CRV.

Also as part of the COTS program NASA is currently (2013 ) being developed privately manned spacecraft Dragon, CST -100 and Dream Chaser could act as CRV.
