Russian cosmonaut Oleg Artemyev has been removed from the upcoming Crew-12 mission to the International Space Station after allegedly photographing restricted SpaceX materials at the company’s Hawthorne training facility.

Artemyev reportedly used his phone to take images of sensitive engines and documents and attempted to remove them from the site, prompting an interagency investigation, according to Russian media.

Roscosmos announced that 43-year-old Andrey Fedyaev, who previously flew on Crew-6 in 2023, will replace Artemyev, citing his “transfer to another job” without addressing the investigation.

Artemyev, 54, has completed three spaceflights totaling 560 days in orbit and also serves as a deputy in the Moscow City Duma, Euro News has reported.

The Crew-12 mission is scheduled to launch no earlier than February 15, 2026, aboard SpaceX’s Crew Dragon under NASA’s Commercial Crew Program, and neither NASA nor SpaceX have commented on the removal or allegations.
