On March 24, 2017, American astronauts Robert Kimbrough and French astronaut Thomas Pesquet performed the spacewalk. The spacewalkers disconnected cables and electrical connections between the “PMA-3” docking adapter and the station’s “Tranquility” module to prepare for the relocation of the docking adapter to the space-facing port on the “Harmony” module, in advance of the delivery of a new docking adapter to the complex next year for commercial crew spaceships owned by Boeing and SpaceX. Kimbrough and Pesquet also lubricated a latching end effector on the Dextre robot, a two-armed handyman provided by the Canadian Space Agency, inspected a radiator valve to look for signs of a small ammonia leak, and replaced cameras outside the Japanese lab module. The EVA lasted six-and-a-half hour. It was the fifth spacewalk for Kimbrough and the second for Pesquet.
