EVA lasted for 5 hours and 58 minutes. On March 23, 2017, Pesquet performed his second career EVA with Shane Kimbrough. The main objective was to prepare the Pressurized Mating Adapter-3 (PMA-3) for installation of the second International Docking Adapter (IDA), which will accommodate future commercial crew vehicle dockings. The PMA-3 provides the pressurized interface between the station modules and the docking adapter. Expedition 50 Commander Kimbrough and Pesquet disconnected cables and electrical connections on PMA-3 to prepare for its robotic move on March 26, 2017. PMA-3 will 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 ship. The spacewalkers also installed on the starboard zero truss (ITS) a new computer relay box equipped with advanced software for the adapter. The two spacewalkers lubricated the latching end effector on 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. The EVA lasted for 6 hours and 34 minutes. On June 2, 2017, MS-03 undocked from the ISS, carrying Pesquet and Novitskiy back to Earth, concluding a 196-day mission in space. Peggy Whitson remained on the ISS and returned on Soyuz MS-04. MS-03 touched down just over 3 hours after undocking, concluding Pesquet's first spaceflight. Pesquet has spent 196 days, 17 hours and 49 minutes in space. Expedition 65/66 On 11 March 2020, ESA announced in a blog post that Pesquet would return to the ISS in the second half of 2021 for a second six-month stay, in which he would become the first European astronaut to launch on board an American Commercial Crew Vehicle. And on July 28, 2020, Pesquet was officially assigned to the SpaceX Crew-2 as a mission specialist alongside NASA astronauts Shane Kimbrough commander of the Crew Dragon, Megan McArthur the pilot, and JAXA astronaut Akihiko Hoshide the other mission specialist. Few hours before the announcement and after a competition to name Pesquet's mission, Pesquet revealed his second mission name as Alpha, after Alpha Centauri, the nearest star system to the Sun, following the French mission naming tradition. Crew Dragon Endeavour was launched on 23 April 2021
