European Space Agency astronaut Alexander Gerst went on his first spacewalk Tuesday with NASA astronaut Reid Wiseman. Working in the moonlight, the duo spent a total of six hours and 13 minutes outside of the International Space Station cleaning and repairing various aspects of their floating home. The astronauts were tethered to the space station during their outing and had a few minutes to take some photographs, some of which were later posted to social media.

Another spacewalk is scheduled to take place next week, the Associated Press reports. Wiseman and fellow American Butch Wilmore will be venturing out of the station to perform more maintenance work.
