October 20, 2021

Expedition 65 was the 65th long-duration mission to the International Space Station that began on April 17, 2021 with the release of the Soyuz MS-17. The crew consisted of members of the SpaceX Crew-1 (for the first two weeks), the Soyuz MS-18 and members of the SpaceX Crew-2 (who arrived on the ISS on April 23). The mission ended on October 17, 2021, with the release of the Soyuz MS-18.

Crew

The crew consisted of members of the Soyuz MS-18 for the duration of the Expedition, members of the SpaceX Crew-1 for the first month of the mission and members of the Crew-2 from late April to October. During the Expedition three astronauts held the role of commander of the International Space Station: Walker from April 17 to 28, Hoshide from April 28 to October 4 and Pesquet from October 4 to 17.

Mission events

SpaceX Crew-2 Launch and Dock

On April 23, 2021 at 9:49 am, the crew of the SpaceX Crew-2 was launched from the Kennedy Space Center aboard the Crew Dragon Endeavor vehicle. At 5:27 pm, the SpaceX Mission Control Center warned the crew of a possible collision with space debris scheduled for 5:43 pm, and ordered them to put on their suits, buckle up their seats, and close the goggles. No corrective maneuver was performed, but the Control Center preferred to have the crew wear suits as a precaution. Once they passed the point of impact without any incident, the crew were able to take off their suits and go to sleep. The journey to the International Space Station proceeded smoothly, culminating in the docking at the front hatch of the ISS Harmony module at 9:08 am on April 24.

Change of command Walker - Hoshide

On April 27, Commander Walker, who held the post for the first ten days of Expedition 65, handed over command of the International Space Station to Japanese astronaut Akihiko Hoshide who will retain the role for the remaining six months of the mission. Walker and his colleagues from SpaceX Crew-1 left the ISS five days later to return to Earth.

Release of the Progress MS-14

The Russian Progress MS-14 cargo vehicle was dropped from the Zvezda module of the Russian Segment of the International Space Station on April 27, after spending more than a year in orbit. During his mission he raised the orbit of the ISS several times which, due to friction with the atmosphere, constantly decays. On April 29 it entered the atmosphere and destroyed itself on the sky of the Pacific Ocean.

SpaceX Crew-1 Release and Landing

After 167 days of mission, on May 2, the crew of the Endeavor vehicle for the SpaceX Crew-1 mission, consisting of Commander Hopkins, Pilot Glover, and mission specialists Noguchi and Walker, disengaged from Harmony's Zenith hatch leaving the Station International Space and start the second part of Expedition 65. After a few hours, the vehicle landed in the Gulf of Mexico, near the coast of Florida; it was the first time since the Apollo 8 mission (1965) that an American vehicle did not land at night.

EVA 1 (VDK-48)

On 2 June Novickij (EV1, red stripes) and Dubrov (EV2, blue stripes) carried out the first extravehicular activity (EVA) of the mission, staying 7 hours and 19 minutes outside the International Space Station to prepare the Pirs module for the his departure scheduled for the summer of 2021, to make way for the new Nauka module. The two cosmonauts, both on their first EVA, replaced a flow control regulator outside Zarja, disconnected the external mechanical links between Pirs and the ISS, moved the EVA equipment including the Strela mechanical arm, reconfigured the antennas and replaced scientific exposure experiments.
