Aleksandr Mikhailovich Samokutyaev, a decorated Russian cosmonaut who completed two long-duration missions aboard the International Space Station (ISS) including during NASA’s final Space Shuttle flight in 2011, has died at the age of 56.
Samokutyaev’s death on June 11, 2025, makes him the first former long-duration ISS resident to pass away in the 26 years since the orbital laboratory began hosting rotating crews continuously. During his time in space, he contributed to scientific research, station maintenance, and international collaboration aboard the ISS.
His legacy includes participation in Expedition 27/28 and Expedition 41/42, missions that advanced our understanding of microgravity’s effects on human health and materials science. Samokutyaev also played a role in the transition from Space Shuttle operations to the era of commercial crew vehicles. Roscosmos, Russia’s space agency, confirmed his passing in a statement issued the following day.
"The leadership and staff of Roscosmos extend their deepest condolences to the family, friends, and colleagues of Aleksandr Mikhailovich," the agency wrote on its official platform.
The cause of Samokutyaev’s death has not been disclosed, and no further details about funeral arrangements or memorial services have been released. As a respected figure in Russia’s space program, his contributions remain tied to the ISS’s history as humanity’s longest continuously inhabited outpost in low Earth orbit.
His passing underscores the rare but real risks taken by those who venture beyond Earth’s atmosphere—and the enduring impact of their work on future space exploration. The ISS continues to serve as a symbol of international cooperation, but the loss of a veteran crew member like Samokutyaev invites reflection on the personal sacrifices behind every mission.
As space agencies prepare for the transition to new orbital platforms and missions to the Moon and Mars, Samokutyaev’s career serves as a reminder of the bridge between past achievements and future ambitions.
