Media are invited to NASA’s Langley Research Center in Hampton, Virginia, on Friday, July 31, to attend a media tour and ribbon-cutting ceremony for the Flight Dynamics Research Facility, the agency’s first new wind tunnel in more than 40 years.

The event will include a brief media availability with:

• NASA Administrator Jared Isaacman
• Dr. Trina Dyal, center director, NASA Langley
• Administrator Edward C. Forst, U.S. General Services Administration

This event is in person only and open to members of the media who are United States citizens or lawful permanent residents. Information about timing will be shared closer to the event. NASA’s media accreditation policy is available online.

Media requesting to participate in person must RSVP no later than 5 p.m. EDT on Wednesday, July 29. Media RSVPs must be sent to Kimiko Booker, kimiko.s.booker@nasa.gov, and Brittny McGraw, brittny.v.mcgraw@nasa.gov, with the following information:

• Legal first and last names (must match government identification)
• Email
• Phone number
• Job title and organization

The wind tunnel opening marks a major milestone in the evolution of NASA and the nation’s aeronautics and space research capabilities. The state-of-the-art facility will support research and technology development that will advance NASA’s aeronautics, exploration, and science goals, including establishing a sustained human presence on the lunar surface through the Artemis program and the development of a Moon Base.

Editor’s Note: This advisory was updated on July 23, 2026, to reflect changes to the mission timeline. 

NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev are wrapping up their 241‑day mission aboard the International Space Station.

The crew and its Soyuz MS-28 spacecraft will undock from the orbiting laboratory’s Rassvet module at 3:03 a.m. EDT Sunday, July 26, heading for a parachute-assisted landing at 6:25 a.m. (3:25 p.m. local time) on the steppe of Kazakhstan, southeast of Dzhezkazgan.

NASA’s live return coverage will stream through a variety of platforms. Learn where to watch online:

https://www.nasa.gov/live

Williams and his crewmates will complete 3,856 orbits and travel more than 102 million miles before returning to Earth. The flight marks the first mission for Williams and Mikaev and the second for Kud‑Sverchkov.

After landing, the crew will fly by helicopter to Karaganda, Kazakhstan, where recovery teams are based. Williams then will return to NASA’s Johnson Space Center in Houston, while Kud‑Sverchkov and Mikaev head back to their training base in Star City, Russia.

NASA’s live return coverage is as follows (all times Eastern and subject to change based on real-time operations):

Saturday, July 25

9:40 a.m. – Coverage of the Space Station Expedition 74/75 change of command ceremony begins.

Kud‑Sverchkov will transfer command of the orbital complex to NASA astronaut Jessica Meir. Expedition 75 officially begins when Soyuz MS‑28 undocks.

11:10 p.m. – Coverage of crew farewells and hatch closing begins.

11:30 p.m. – Hatch closing

Sunday, July 26

2:30 a.m. – Coverage of undocking begins.

3:03 a.m. – Undocking

5:15 a.m. – Coverage of deorbit and landing begins.

5:31 a.m. – Deorbit burn

6:25 a.m. – Landing

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs not possible on Earth. The space station helps NASA understand and overcome the challenges of human spaceflight, expand commercial opportunities in low Earth orbit, and build on the foundation for long-duration missions to the Moon, as part of the Artemis program, and to Mars.
