NASA astronaut Chris Williams and Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev landed in their Soyuz MS-28 capsule near Zhezkazgan, Kazakhstan, on July 26, 2026, after an 8-month mission aboard the International Space Station. The crew’s 241-day stay included 3,856 orbits of Earth and over 102 million miles traveled, according to NASA. The landing, which occurred at 5:27 a.m. CDT (3:27 p.m. local time), marked the end of Williams’ first spaceflight and Kud-Sverchkov’s second, while Mikaev completed his debut mission.
Mission Overview and Space Station Work
The crew launched to the ISS on November 27, 2025, aboard the Soyuz MS-28. Williams also completed two spacewalks, including work on the station’s robotic arm and solar power system. Kud-Sverchkov and Mikaev contributed to maintenance tasks, including a spacewalk outside the Russian segment of the station.
Williams’ work on the ISS included advancing in-space manufacturing techniques for high-performance electronics, a focus area highlighted by NASA. The crew’s research aims to benefit both space exploration and terrestrial applications, such as improving medical technologies. The work aboard the station helps improve life on Earth and prepare for future human missions to the Moon and Mars,
NASA stated in its mission summary.
Landing Details and Crew Reactions
Russian recovery teams quickly reached the capsule, assisting the astronauts out of the cramped spacecraft. Kud-Sverchkov, speaking from a recliner after landing, said, I am feeling better and better with each moment.
Everything was smooth and perfect.
The crew underwent medical checks before being flown by helicopter to Karaganda, Kazakhstan. Williams then traveled to NASA’s Johnson Space Center in Houston, while Kud-Sverchkov and Mikaev returned to Star City near Moscow.
Williams’ Background and Career
Williams, a Montgomery County native, was born in New York City but considers Potomac his hometown. He graduated from Montgomery Blair High School and earned a physics degree from Stanford University before obtaining a doctorate from MIT. Prior to joining NASA in 2021, Williams worked as a researcher focused on imaging and radiation treatments for cancer patients.
Williams’ career also includes roles as an Eagle Scout, private pilot, and former volunteer firefighter and EMT.
International Collaboration and Future Missions
The mission underscored the continued collaboration between the U.S. and Russia on the ISS, despite geopolitical tensions. The crew was replaced by a new team, including NASA astronaut Anil Menon and Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina, who arrived on July 14, 2026, according to Reuters. NASA Administrator Jared Isaacman attended the launch, marking his first visit to the Baikonur Cosmodrome in eight years.
The ISS has hosted continuous human presence for over 25 years, facilitating scientific breakthroughs and preparing for future lunar and Martian missions. The station remains a critical platform for international cooperation in space exploration.
The successful return of Williams and his crew highlights the resilience of space missions amid global challenges. As the ISS continues its work, the next phase of exploration—targeting the Moon and Mars—relies on the data and experiences gathered during missions like this one.
