Two Russian cosmonauts are set to put on their spacesuits and leave the confines of their outer space home to perform maintenance on the International Space Station Monday.
Veteran cosmonauts Gennady Padalka and Mikhail Kornienko of the Russian Federal Space Agency (Roscosmos) are scheduled to spend just shy of six and a half hours outside station to complete various tasks.
During their spacewalk, they will be rigging new equipment, performing a photographic inspection of the exterior of the station, replacing and maintaining external antennas, and cleaning a window of exhaust deposits from visiting spacecraft.
TIME is producing a series of films about the yearlong mission of Kornienko and American astronaut Scott Kelly. Watch the series here.
