NASA Astronaut Chris Williams Returns to Earth After 241 Days and 102 Million Miles in Space
Williams and two Roscosmos cosmonauts completed 3,856 orbits and more than 102 million miles during the mission, NASA said.
- NASA astronaut Chris Williams landed safely in Kazakhstan on Sunday, July 26, 2026, aboard the Russian Soyuz MS-28 spacecraft after completing a 241-day mission aboard the International Space Station .
- During the 241-day stay, Williams and his crewmates, Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev, completed 3,856 orbits of Earth and traveled more than 102 million miles.
- Throughout the mission, Williams conducted scientific research on potential cancer treatments and material manufacturing while performing two spacewalks, including replacing a faulty wrist joint on the ISS's Canadarm2 robotic arm.
- Following medical evaluations in Kazakhstan, Williams will return to NASA's Johnson Space Center in Houston for post-flight rehabilitation, while station responsibilities have transitioned to Expedition 75.
- The successful return underscores the ongoing partnership between NASA and Roscosmos despite geopolitical tensions, with astronauts maintaining a continuous human presence aboard the ISS for more than 25 years.

Martian Space Suits Will Need To Be 40% Lighter
Long before a human ever sets foot on the Red Planet, we already know how hard the environment is. Once one finally does, the only things protecting them from that harsh environment will be the infrastructure we’ve built up there, and the spacesuit that keeps that in a protective bubble. Unfortunately, modern space suits aren’t built with Martian gravity, which is 3/8ths of Earth’s, in mind. To prove that point, a team of NASA and industry engin…
A NASA instrument the size of a toaster, riding inside the Perseverance rover, converted Martian air into 122 grams of breathable oxygen between 2021 and 2023 — enough to keep a small dog alive for 10 hours, and proof that astronauts could one day make the fuel to fly themselves home
The strangest thing about MOXIE is that 122 grams can sound both tiny and enormous. On Earth, it is a little over the mass of a chocolate bar. On Mars, it was the total amount of oxygen that a machine made from the planet’s own atmosphere, 225 million kilometres from the nearest repair bench. NASA compared it with the amount a small dog breathes in about 10 hours. That is a charming way to make the number tangible, but it can also obscure what t…
NASA Astronaut Chris Williams Returns to Earth
NASA/Bill Ingalls NASA astronaut Chris Williams is all smiles in this July 26, 2026, photo taken shortly after he landed with Expedition 74 Roscosmos cosmonauts Sergey Kud-Sverchkov, and Sergei Mikaev in Kazakhstan. This was Williams’ first mission. Williams spent eight months aboard the International Space Station, where he supported a wide range of scientific investigations and technology demonstrations. He also completed two spacewalks to pre…
After 241 days in orbit this NASA astronaut is finally home
NASA astronaut Chris Williams and two Roscosmos cosmonauts are back on Earth after spending 241 days aboard the International Space Station. Their journey covered more than 102 million miles and included 3,856 trips around the planet.
