Concluding an eight-month science mission aboard the International Space Station, NASA astronaut Chris Williams returned to Earth on Sunday alongside Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev.
The crew made its safe, parachute-assisted landing at 5:27 a.m. CDT (3:27 p.m., Kazakhstan time), southeast of Dzhezkazgan, after departing the space station at 2:03 a.m., aboard the Soyuz MS-28 spacecraft.
The crew was in space for 241 days, orbiting the Earth 3,856 times and traveling more than 102 million miles. They launched to the International Space Station on Nov. 27, 2025. The mission was the first for Williams and Mikaev and the second for Kud-Sverchkov.
While aboard the orbiting laboratory, Williams supported a wide range of scientific investigations and technology demonstrations. He helped advance research for new cancer treatments and improved in-space manufacturing of materials used in high-performance computers and electronics. Williams also completed two spacewalks to prep for space station power system upgrades and to replace a faulty joint on the Canadarm2 robotic arm. The crew’s work aboard the space station helps improve life on Earth and prepare for future human missions to the Moon and Mars.
