Core Event: Soyuz MS-28 Touches Down in Kazakhstan
On July 26, 2026, NASA astronaut Chris Williams and Roscosmos cosmonauts Sergei Kud-Sverchkov and Sergei Mikaev landed in their Soyuz MS-28 capsule in the steppes southeast of Dzhezkazgan, Kazakhstan. The parachute-assisted descent concluded a 241-day stay aboard the International Space Station (ISS). After landing, the trio was taken by helicopter to Karaganda, where Williams will travel to NASA’s Johnson Space Center in Houston and the Russian cosmonauts will return to the training center at Star City, outside Moscow.
Background & Context
The United States and Russia, former Cold-War rivals, have maintained a continuous partnership on the ISS since the early 2000s. Although diplomatic relations have been strained since Moscow’s 2022 invasion of Ukraine, both space agencies have kept crew exchanges active, with each nation launching astronauts on the other’s spacecraft. The recent flight continued this pattern, underscoring the separation of geopolitical tensions from joint scientific endeavors in low-Earth orbit.
Timeline
- July 14 – NASA astronaut Anil Menon and Roscosmos cosmonauts Pyotr Dubrov and Anna Kikina arrived at the ISS aboard Soyuz MS-29, launching from the Russia-operated Baikonur Cosmodrome. Their arrival marked the start of Expedition 75.
- July 26, 2026 – The Williams-Kud-Sverchkov-Mikaev crew returned to Earth in Soyuz MS-28, completing the preceding Expedition 74 mission.
Data & Statistics
- Mission duration: 241 days in orbit (NASA).
- Orbital passes: 3,856 circuits around Earth (NASA).
- Distance traveled: more than 102 million miles (NASA).
- U.S. spacewalks: Williams performed two extravehicular activities to prepare power-system upgrades and replace a faulty joint on the Canadarm2 robotic arm (NASA).
- Russian spacewalk: Roscosmos reported one EVA to install equipment for the Sun-Terahertz scientific experiment (Roscosmos).
- Resupply: Two Progress MS cargo spacecraft delivered water, fuel, and atmospheric gases to the station during the crew’s stay (Roscosmos).
Official Statements & Responses
NASA described the mission as a “significant milestone” for both agencies, noting that the crew’s research aimed to “improve life on Earth” and to lay groundwork for future Moon and Mars missions. The agency highlighted Williams’ work on cancer-treatment research and on-orbit manufacturing of high-performance computer materials.
Roscosmos confirmed the successful landing time of 1:27 p.m. Moscow time (10:27 GMT) and emphasized the Russian EVA’s contribution to the Sun-Terahertz experiment, which will study solar terahertz radiation.
NASA Administrator Jared Isaacman attended the July 14 launch from Baikonur, marking the first visit by a NASA chief to the site in eight years, a gesture the agency presented as a reaffirmation of the bilateral partnership.
Why It Matters
The safe return of the U.S.–Russian crew illustrates the durability of ISS cooperation despite broader political discord. Scientific outcomes—including biomedical studies, advanced materials research, and solar-physics experiments—feed directly into NASA’s Artemis lunar program and its long-term Mars objectives. Continued crew exchanges also provide a diplomatic channel that sustains dialogue between the two space powers, reinforcing the ISS’s role as a platform for both exploration and international stability.
