Foto de stock - NASA astronaut Ron Garan, Expedition 27 flight engineer, gives a thumbs up signal to onlookers after having his Russian Sokol suit's pressure checked in preparation for his launch onboard the Soyuz TMA-21 rocket. He will join two Russian cosmonauts and fellow crew members -- Soyuz commander Alexander Samokutyaev and Andrey Borisenko, flight engineer -- for the launch from Baikonur, Kazakhstan, April 5, 2011 (Kazakhstan time). The Soyuz, which has been dubbed Gagarin, 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.
