ISS Expedition 74/75 Ends 241-Day Mission
After a 241-day mission aboard the International Space Station, NASA astronaut Chris Williams and Roscosmos cosmonauts Sergei Kud-Sverchkov and Sergei Mikaev landed safely on the Kazakh steppe aboard the Soyuz MS-28, with Williams headed to Houston and the others to Star City. The crew—Williams and Mikaev on their first spaceflight, Kud-Sverchkov on his second—represented continued US-Russia cooperation on the ISS amid broader tensions. They conducted a range of science and technology work, including cancer research, in-space manufacturing, two spacewalks to upgrade power systems, and replacing a faulty Canadarm2 joint. Launched from Baikonur on November 27, 2025, the trio completed 241 days, 3,856 orbits, and more than 102 million miles. The landing involved a de-orbit burn and parachute-assisted touchdown, followed by recovery teams providing medical checks and debriefs. The mission highlights ongoing international collaboration in space as Expedition 75 readiness unfolds under NASA leadership.
