BAIKONUR, KAZAKHSTAN - APRIL 05: In this handout image provided by the National Aeronautics and Space Administration (NASA), Expedition 27 NASA Flight Engineer Ron Garan gives a thumbs up to onlookers after having his Russian Sokol suit pressure checked in preparation for his launch onboard the Soyuz TMA-21 rocket with fellow crew members, Soyuz Commander Alexander Samokutyaev and Flight Engineer Andrey Borisenko from the Baikonur Cosmodrome on April 5, 2011. The Soyuz, which has been dubbed "Gagarina" is launching one week shy of the 50th anniversary of the launch of Yuri Gagarin from the same launch pad in Baikonur on April 12, 1961 to become the first human to fly in space.
