Expedition 74 is the 74th long-duration expedition to the International Space Station (ISS). The expedition began with the departure of Soyuz MS-27 on 9 December 2025 with NASA astronaut Michael Fincke taking over the ISS command and is expected to conclude with the undocking of Soyuz MS-28 on 26 July 2026. It continues the extensive scientific research conducted aboard the ISS, focusing on various fields, including biology, human physiology, physics, and materials science. The crew members also maintain and upgrade the space station systems.
On January 7, 2026, NASA announced that SpaceX Crew-11 would return to Earth about a month early due to an undisclosed "medical situation" affecting one crew member.[2][3][4] The incident led to the cancellation of two planned spacewalks on January 8 and 15, including preparations for installation of ISS Roll-Out Solar Arrays (iROSAs) and other maintenance tasks on the Harmony module and the station’s S6 and S4 truss.[5] NASA administrator Jared Isaacman confirmed the early return on January 8.[6]
On January 12, Fincke handed over command of the space station to Kud-Sverchkov. Crew-11 departed with Cardman, Fincke, Yui, and Platonov on January 14 approximately one month ahead of schedule.[7][8][9][10] Fincke later stated that he experienced the medical event, was stabilized by crewmates under the guidance of NASA flight surgeons, and returned early to access advanced medical imaging unavailable on the station. After splashdown, he was treated at Scripps Memorial Hospital La Jolla and later reported he was "doing very well".[4]
The expedition has seen one spacewalk so far. On March 18, Meir and Williams performed a 7-hour, 2-minute spacewalk and prepared the 2A power channel for future installation of the iROSA to provide additional power. Two NASA astronauts will prepare the station’s 3B power channel for a future iROSA installation.[12][13]

The Prichal aft, forward, starboard, and aft ports all have yet to be used since the module originally docked to the station and are not included in the table.
