Expedition 47 Russian cosmonaut Alexei Ovchinin of Roscosmos, center, describes a poster created for him and his fellow crew members, NASA astronaut Jeff Williams, left, and Russian cosmonaut Oleg Skripochka during a crew press conference at the Gagarin Cosmonaut Training Center (GCTC), Friday, Feb. 26, 2016, in Star City, Russia. The poster, a lighthearted take on the famous Russian painting "Burlaki na Volge" by Ilya Repin, depicts Ovchinin, Skripochka, and Williams as part of a crew of Burlaks, or barge haulers, dragging a barge on the Volga river. Ovchinin has chosen Burlak as the Soyuz TMA-20M call sign, paying homage to his hometown of Rybinsk, Russia, one of the oldest Slavic settlements on the Volga River and the site of much Burlak labor from the 17-20th centuries of the Russian Empire.
