Chris Williams and his crewmates spent 241 days in space. They completed 3,856 orbits of Earth and traveled over 102 million miles. The Soyuz MS-28 spacecraft landed safely on July 26.

A NASA astronaut named Chris Williams has returned to Earth after an eight-month science mission aboard the International Space Station. He came back with two other astronauts from Russia: Sergey Kud-Sverchkov and Sergei Mikaev.

The Soyuz MS-28 spacecraft landed safely by parachute on July 26 at 5:27 a.m. CDT (3:27 p.m., Kazakhstan time) southeast of Dzhezkazgan. The crew had been in space for 241 days after launching to the International Space Station on November 27, 2025.

During their mission, Williams and his crewmates completed 3,856 orbits of Earth and traveled more than 102 million miles. This was a significant achievement for NASA's space program.

Williams contributed to many scientific studies and technology demonstrations while living aboard the orbiting laboratory. His work included research that could help develop new cancer treatments. He also helped investigate ways to improve the production of materials in space for use in high-performance computers and electronics.

The crew's research and maintenance work may benefit people on Earth while also helping NASA prepare for future human exploration of the Moon and Mars.
