Spaceflight Experience:
Expedition 37/38 (September 25 through March 10, 2014). On September 25, 2013, Hopkins launched from the Baikonur Cosmodrome in Kazakhstan along with Russian cosmonauts Oleg Kotov and Sergey Ryazanskiy. They were welcomed to the space station by Expedition 37 commander Fyodor Yurchikhin of Roscosmos, Karen Nyberg of NASA and Luca Parmitano of the European Space Agency. They were later joined by Expedition 39 commander Koichi Wakata of the Japan Aerospace Exploration Agency (JAXA) and flight engineers Russian cosmonaut Mikhal Tyurin and U.S. astronaut Rick Mastracchio. During his stay aboard the space station, Hopkins and Mastracchio conducted a pair of U.S. spacewalks to change out a degraded pump module for a total of 12 hours and 58 minutes. Hopkins, Kotov and Ryazanskiy returned to Earth on March 10, 2014, after 166 days in space. During the expedition, the crew completed 2,656 orbits of the Earth and traveled more than 70 million miles.
