Beginning with 2025, the flight duration of Soyuz MS spacecraft is set to be increased from six to seven-nine months, which will help economize on a spaceship every two years.

The agreement will additionally stipulate two flights by NASA astronauts aboard the Soyuz MS-28 and Soyuz MS-29 spaceships in 2025 and 2026, correspondingly, and three flights by Roscosmos cosmonauts on board Crew Dragon spacecraft (another additional flight in 2025, one flight in 2026 and one flight in 2027).

NASA Astronaut Chris Williams Assigned to First Space Station Mission

NASA astronaut Chris Williams will embark on his first mission to the International Space Station, serving as a flight engineer and Expedition 74 crew member.

Williams will launch aboard the Roscosmos Soyuz MS-28 spacecraft in November, accompanied by Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev. After launching from the Baikonur Cosmodrome in Kazakhstan, the trio will spend approximately eight months aboard the orbiting laboratory.

During his expedition, Williams will conduct scientific investigations and technology demonstrations that help prepare humans for future space missions and benefit humanity.

Selected as a NASA astronaut in 2021, Williams graduated with the 23rd astronaut class in 2024. He began training for his first space station flight assignment immediately after completing initial astronaut candidate training.

Williams was born in New York City, and considers Potomac, Maryland, his hometown. He holds a bachelor’s degree in Physics from Stanford University in California and a doctorate in Physics from the Massachusetts Institute of Technology in Cambridge, where his research focused on astrophysics. Williams completed Medical Physics Residency training at Harvard Medical School in Boston. He was working as a clinical physicist and researcher at the Brigham and Women’s Hospital in Boston when he was selected as an astronaut.

The mission was originally supposed to use Soyuz-MS vehicle No. 759, which was the next on the assembly line at RKK Energia's ZEM factory in Korolev, near Moscow.

However, during routine post-production tests at ZEM's Checkout and Test Facility, KIS, Vehicle No. 759 reportedly suffered major damage to its thermal protection system, which could not be repaired in time for the Expedition 74 launch at the end of 2025. According to one source, quoting an officer within the military certification service, Voennaya Priemka, which traditionally oversees quality control in the Russian rocket and space industry, the ship's main thermal control heat shield, attached to the base of the Descent Module, SA, was accidentally jettisoned, perhaps by a stray signal triggering the pyrotechnic bolts, connecting the Frisbee-shaped structure to the capsule. According to another source, the thermal layers of the shield peeled off, as a result of botched thermal tests.

In any case, as of late October 2025, neither Roskosmos nor the official media had confirmed the fact of an incident, but the photos of the Soyuz MS-28 spacecraft undergoing processing in Baikonur, which accompanied press-releases about the launch campaign, showed No. 753 on the flight-worthy ship.

That particular Soyuz-MS, along with Vehicle No. 752, was initially reserved for "tourist" missions...
