NASA astronaut Chris Williams returned to Earth on Sunday alongside Roscosmos cosmonauts Sergei Kud-Sverchkov and Sergei Mikayev, completing an eight-month scientific mission aboard the International Space Station (ISS).
According to NASA, the crew landed safely by parachute southeast of Zhezkazgan, Kazakhstan, after departing the orbital laboratory aboard the Soyuz MS-28 spacecraft.
The three crew members spent 241 days in space, orbiting Earth 3,856 times and travelling more than 102 million miles.
They launched to the ISS on 27 November 2025. The mission was the first spaceflight for Williams and Mikayev, and the second for Kud-Sverchkov.
During his time aboard the station, Williams carried out a wide range of scientific experiments and technology demonstrations.
His work included research aimed at advancing potential cancer treatments and improving the space-based manufacturing of materials used in high-performance computers and electronics.
Williams also completed two spacewalks, helping prepare upgrades to the station's power system and replacing a faulty connection on the Canadarm2 robotic arm.
NASA said the crew's work aboard the ISS contributes to improving life on Earth while helping prepare for future crewed missions to the Moon and Mars.
