Expedition 66 was the 66th long-duration expedition to the International Space Station. The mission began after the departure of Soyuz MS-18 on 17 October 2021.[2] It was commanded by European Space Agency astronaut Thomas Pesquet, the fourth European astronaut to command the ISS and first French astronaut to command the orbital laboratory,[3] until 8 November 2021, when Russian cosmonaut Anton Shkaplerov, who arrived aboard Soyuz MS-19, and took over his command.[4]
Pesquet was transported to the ISS on SpaceX Crew-2 in April 2021, joined by NASA astronauts Shane Kimbrough and Megan McArthur and Japan Aerospace Exploration Agency (JAXA) astronaut Akihiko Hoshide.[5] Crew-2 from Expedition 65 extended their tour of duty on the ISS to become part of Expedition 66,[6] along with Russian cosmonaut Pyotr Dubrov and NASA astronaut Mark Vande Hei, who both launched on Soyuz MS-18 and returned to Earth on Soyuz MS-19, following their extended mission. Russian cosmonaut Shkaplerov launched on Soyuz MS-19, along with two participants in the joint film project between Roscosmos and Channel One, The Challenge: film director Klim Shipenko and actress Yulia Peresild.
SpaceX Crew-3, launched 10 November 2021, carried NASA astronauts Raja Chari, Thomas Marshburn, and Kayla Barron and ESA astronaut Matthias Maurer to the ISS.[7] At the end of Expedition 66, they remained on the ISS as part of Expedition 67 while Dubrov and Vande Hei returned to Earth aboard Soyuz MS-19.[8] However, continued international collaboration has been thrown into doubt by the 2022 Russian invasion of Ukraine and related sanctions on Russia.[9]
