Aleksandr Samokutyaev, a 56-year-old Russian cosmonaut and former resident of the International Space Station, has died. He becomes the first former ISS crew member to pass away, according to reports from the Russian space agency.

Samokutyaev's career included two expeditions to the ISS, during which he conducted two spacewalks. His total time in space amounted to 322 days, a significant duration that contributed to the station's early assembly and operations.

The cosmonaut's death marks a somber milestone for the ISS program, now in its third decade. It underscores the human toll behind space exploration, even as attention focuses on robotic missions and commercial ventures.

Further details about the cause of death were not immediately available. The Russian space agency typically releases such information through official channels after family notifications.

As the first former ISS crew member to die, Samokutyaev's legacy highlights the physical and personal sacrifices made by early long-duration spacefarers.
