(Phys.org)—The ATV-derived service module, sitting directly below Orion's crew capsule, will provide propulsion, power, thermal control, as well as supplying water and gas to the astronauts in the habitable module.

This collaboration between ESA and NASA continues the spirit of international cooperation that forms the foundation of the .

ATV is a versatile showcase of European technology performing many functions during a mission to the International Space Station. The space freighter reboosts the Station and can even push the orbital complex out of the way of . While docked, ATV becomes an extra module for the astronauts. Lastly, at the end of its mission it leaves the Space Station with waste materials.

"ATV has proven itself on three flawless missions to the Space Station and this agreement is further confirmation that Europe is building advanced, dependable spacecraft," said Nico Dettmann, Head of ATV's production programme.

Thomas Reiter, ESA director of and Operations says: "NASA's decision to cooperate with ESA on their exploration programme with ESA delivering a critical element for the mission is a strong sign of trust and confidence in ESA's capabilities, for ESA it is an important contribution to ." 

Dan Dumbacher, deputy associate administrator for exploration systems development at NASA headquarters in Washington DC, agrees: "It is a testament to the engineering progress made to date that we are ready to begin integrating designs of an ESA-built service module with Orion." 

The first Orion mission will be an uncrewed lunar fly-by in 2017, returning to at a speed of 11 km/s ­– the fastest reentry ever.

An excellent reuse of the ATV. It should greatly improve the early Orion missions by extending them without modifying the baseline module.
