Expedition 50 Commander Shane Kimbrough of NASA at work outside the International Space Station on Jan. 13, 2017, in a photo taken by fellow spacewalker Thomas Pesquet of the European Space Agency. During the nearly six-hour spacewalk, the two astronauts successfully installed three new adapter plates and hooked up electrical connections for three of the six new lithium-ion batteries on the International Space Station. This was the second spacewalk in a week for Kimbrough and the fourth of his career, and the first for Pesquet.
