[NASA Press Release - 03.10.2007]
NASA and the Russian Federal Space Agency Roscosmos have agreed to fly two Russian scientific instruments on NASA spacecraft that will conduct unprecedented robotic missions to the moon and Mars.
NASA Administrator Michael Griffin and Roscosmos head Anatoly Perminov signed agreements in Moscow on Oct. 3 to add the instruments to two future missions: the Lunar Reconnaissance Orbiter, scheduled to launch in October 2008, and the Mars Science Laboratory, an advanced robotic rover scheduled to launch in 2009.
BBC reports that the US has rejected a Moscow proposal that the two countries join forces to explore the Moon. "We were ready to co-operate, but for unknown reasons, the United States have said they will undertake this programme themselves," Anatoly Perminov said.
US space agency NASA has said it plans to start work on a base on the Moon when astronauts return there in 2020. NASA has not commented on Mr Perminov's statement, reported by Interfax news. NASA and Russia's federal space agency Roskosmos have experience of working together on the International Space Station (ISS).
