The European Space Agency (ESA) on Wednesday signed a deal with its Russian counterpart Roscosmos to cooperate on two Mars exploration projects, Russia's Interfax news agency reported.
Under the deal, the ESA will use Russia's Proton rocket as part of its Exomars project to send a robotic rover to the Mars surface and buy Russian parts for the rover's power supply system.
The deal will also see Russia's Phobos-Grunt project -- to send a probe to Mars' Phobos moon in October 2009 -- use the ESA's terrestrial communication facilities during its mission.
Interesting. Wasn't Exomars supposed to have a US launch? Or am I mixing things up?
