In Baikonur, Kazakhstan, Expedition 51 backup crewmember Randy Bresnik of NASA (right) takes pictures of a traditional Kazakh “yurt” or tent, while his backup crewmate, Sergey Ryazanskiy of the Russian Federal Space Agency (Roscosmos) listens to a description of the display in a local museum during pre-launch activities April 7. They are serving as backups to Fyodor Yurchikhin of Roscosmos and Jack Fischer of NASA, who will launch April 20 on the Soyuz MS-04 spacecraft from the Baikonur Cosmodrome for a four and a half month mission on the International Space Station.
