ESA astronaut Alexander Gerst and his colleague NASA astronaut Serena Auñón-Chancellor support NASA astronauts Andrew Feustel and Ricky Arnold during their spacewalk from the inside of the International Space Station on 14 June 2018. In preparation for the arrival of commercial crew vehicles, Feustel and Arnold installed new cameras outside the Harmony module. Auñón-Chancellor and Gerst controlled the Canadarm2 robotic arm when Arnold mounted it to replace a camera and a light that were too far to reach when tethered to the main body of the International Space Station. Gerst posted this picture of operations on the inside, commenting: "Alone in the night. Our two buddies Andrew Feustel and Ricky Arnold on a space walk last week, installing wifi antennas for external experiments. We were happy to help them out the door - but we were even happier to help them back in."
Alexander Gerst is currently on his second mission to the International Space Station for Expeditions 56 and 57. The mission is part of ESA’s vision to use Earth-orbiting spacecraft as a place to live and work for the benefit of European society while using the experience to prepare for future voyages of exploration further into the Solar System.
