NASA Astronaut Chris Williams Assigned to First Space Station Mission

WASHINGTON, April 3, 2025 /PRNewswire/ -- 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.

For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is able to more fully focus its resources on deep space missions to the Moon and Mars.
