ESA astronaut Alexander Gerst shared this photo on social media with the comment: "Safe to say, this was the most amazing thing I have done in my life. The pump module I carry here has a mass of 400 kg. I could move it with my little finger." Gerst spent six hours and 13 minutes outside the International Space Station with NASA astronaut Reid Wiseman on Tuesday, October 7, 2014. This was the first spacewalk for both astronauts but they performed well in the weightlessness of orbit. The pair worked together to move a 385 kg pump from the Station's truss to a permanent stowage location near the US Destiny module. After attaching the pump, Gerst took the arm for a last ride to park it and prepare it for its next use, berthing visiting spacecraft. Here, he had his hands free and time to take a few photographs, such as this one. His feet are strapped to the arm and tethers secure him to the arm. To the right is the commercial Dragon supply vessel.
