At the Baikonur Cosmodrome in Kazakhstan, Expedition 27 Flight Engineer Andrey Borisenko (left), Soyuz Commander Alexander Samokutyaev (center) and NASA Flight Engineer Ron Garan walk past their Soyuz booster during dress rehearsal activities March 22, 2011. The booster, like the Soyuz TMA-21 spacecraft in which they will launch, is adorned with the name “Gagarin” and the likeness of Russian cosmonaut Yuri Gagarin, the first human in space. The Soyuz TMA-21 is scheduled for launch on April 5 (April 4, U.S. time), just one week shy of the 50th anniversary of Gagarin’s historic journey into space from the same launch pad that the Expedition 27 crew will begin their mission from.
