NASA Astronaut Chris Williams and Crew Prepare for Soyuz MS-28 Return to Earth

NASA astronaut Chris Williams and two Roscosmos cosmonauts are preparing to return to Earth following a 241-day mission aboard the International Space Station, with undocking scheduled aboard the Soyuz MS-28 spacecraft for Sunday, July 26, after completing thousands of orbits and millions of miles of travel.

Mission Timeline and Return Details for Soyuz MS-28

The return sequence for the Expedition 74 crew begins on Saturday, July 25, with a change-of-command ceremony at 9:40 a.m. Eastern, as NASA reported. During the ceremony, Roscosmos cosmonaut Sergey Kud-Sverchkov will hand over command of the orbital complex to NASA astronaut Jessica Meir. Official transition to Expedition 75 coincides with the physical departure of the spacecraft when Soyuz MS-28 undocks.

According to NASA, crew farewells and hatch closing coverage begins at 11:10 p.m. on Saturday, with the hatch closing officially at 11:30 p.m. The Soyuz MS-28 capsule will then undock from the station’s Rassvet module at 3:02 a.m. EDT on Sunday, July 26, following undocking coverage starting at 2:30 a.m. Following a deorbit burn at 5:32 a.m., the spacecraft will execute a parachute-assisted landing on the steppe of Kazakhstan, southeast of Dzhezkazgan, at 6:26 a.m. Eastern, which corresponds to 3:26 p.m. local time.

Crew Milestones and Final Destinations

The returning crew includes NASA astronaut Chris Williams alongside Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev. By the time their capsule touches down, the flight will total 3,856 orbits and cover more than 102 million miles, according to agency records.

This journey marks distinct milestones for the individual crew members. The flight is the first space mission for both Williams and Mikaev, while serving as the second mission for Kud-Sverchkov.

Recovery teams positioned in Kazakhstan will transport the crew by helicopter to Karaganda immediately after landing. From there, the travelers split paths: Williams will travel to the agency’s Johnson Space Center in Houston, while Kud-Sverchkov and Mikaev are due to return to their training base in Star City, Russia.

Broader Context of Continuous Orbital Operations

The International Space Station has hosted continuous human presence for more than 25 years, advancing scientific knowledge and making research breakthroughs not possible on Earth.

Agency materials note that the accumulated data and operational experience from these continuous missions help NASA understand and overcome the challenges of human spaceflight. These efforts support commercial opportunities in low Earth orbit while building on the foundation for long-duration missions to the Moon, as part of the Artemis program, and eventually to Mars.
