ESA astronaut Thomas Pesquet during his first spacewalk, on Friday 13 January 2017. Together with NASA astronaut Shane Kimbrough, he spent five hours and 58 minutes outside the Space Station to complete a battery upgrade to the outpost’s power system.
Thomas commented on this picture: "This is how big the International Space Station! You can really get disoriented and lost at night, especially when moving and rotating in all directions."
