The next crew of the International Space Station have been undergoing final training in Russia. It's in preparation for July's launch from the Baikonur launchpad in Kazakhstan.
Flight Engineers Sunita Williams from the US, Akihiko Hoshide from Japan, and Russian Yuri Malenchenko, were put through their paces at the "Gagarin Cosmonauts Training Centre" near Moscow. They'll fly to the ISS on July 15th. They were joined in Tuesday's exercises by their backup space crew. Since the retirement of NASA's space shuttle fleet last year, the US is dependent on Russia to fly astronauts to the ISS at a cost of 60 million US dollars per astronaut.
