(NASA) – This footage was taken by ESA astronaut Thomas Pesquet during a spacewalk on the International Space Station on Friday, March 24.
He was joined on the spacewalk by NASA astronaut Shane Kimbrough.
The primary task was to prepare the Pressurized Mating Adapter-3 (PMA-3) for installation of the second International Docking Adapter, which will accommodate commercial crew vehicle dockings.
The PMA-3 provides the pressurized interface between the station modules and the docking adapter.
The pair disconnected cables and electrical connections on PMA-3 to prepare for its robotic move, which took place on Sunday, March 26. PMA-3 was be moved from the port side of the Tranquility module to the space-facing side of the Harmony module, where it will become home for the docking adapter, which will be delivered on a future flight of a SpaceX Dragon cargo spacecraft.
The spacewalkers also installed on the starboard zero truss a new computer relay box equipped with advanced software for the adapter.
The two spacewalkers lubricated the latching end effector on the Special Purpose Dexterous Manipulator “extension” for the Canadarm2 robotic arm, inspected a radiator valve suspected of a small ammonia leak and replaced cameras on the Japanese segment of the outpost.
Radiators are used to shed excess heat that builds up through normal space station operation.
