NASA astronaut Chris Williams and two Russian cosmonauts safely returned to Earth on July 26, 2026, concluding a 241-day mission aboard the International Space Station [1]. The Soyuz MS-28 spacecraft landed southeast of Dzhezkazgan in Kazakhstan [1].
During their extended orbital stay, the crew completed 3,856 Earth orbits and traveled over 102 million miles [1]. Williams, along with Russian cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, conducted numerous scientific investigations throughout their time in space [1]. Their research portfolio included cancer treatment studies and advanced manufacturing techniques for high-performance computing materials [1]. The expedition team also performed two spacewalks to support station operations [1].
Williams launched on November 27, 2025, marking his first spaceflight, while Mikaev also embarked on his inaugural space mission [1]. The crew landed at 5:27 a.m. CDT on their return day [1].
