Aleksandr Samokutyaev, 56, First Former Long-Duration ISS Resident to Die
Russian cosmonaut Aleksandr Samokutyaev has died at the age of 56. His death on Wednesday, June 17, 2026, marks a sad first for the International Space Station program. He is the first former long-duration resident of the ISS to pass away in the station’s 26-year history.
Samokutyaev served twice as a crew member aboard the ISS. His missions included time during the final US space shuttle flight in 2011. The cause of his death has not been made public.
Russia’s space agency, Roscosmos, released a statement expressing condolences to his family and loved ones. The space community now mourns the loss of a man who spent months living and working in orbit.
The Announcement: Death and Condolences
News of Samokutyaev’s death first appeared on collectSPACE.com, a space history news site, on Wednesday. The site published an obituary confirming his passing. Ars Technica later reported the story, noting the historic nature of the loss.
Roscosmos issued a formal statement. The agency offered its deepest sympathies to Samokutyaev’s family, friends, and colleagues. The statement did not provide details about the cause of death or funeral arrangements.
Samokutyaev’s death is a reminder of the human side of space exploration. The ISS has been continuously occupied since November 2000. Over that time, 155 other cosmonauts and astronauts have served as expedition crew members. None of them had died until now.
Who Was Aleksandr Samokutyaev?
Aleksandr Samokutyaev was born in 1970 in Russia. He trained as a cosmonaut and flew to the ISS twice. His first mission was on Soyuz TMA-21 in 2011. He served as a flight engineer for Expeditions 27 and 28.
His second mission came in 2014. He flew aboard Soyuz TMA-14M and served as part of Expeditions 41 and 42. In total, he spent about six months in space on each trip.
Samokutyaev’s first mission overlapped with the final US space shuttle flight, STS-135, in July 2011. But he did not fly on the shuttle. He arrived at the ISS on a Russian Soyuz spacecraft. The shuttle’s crew was separate. Still, his presence on the station during that historic moment linked him to the end of the shuttle era.
During his time in orbit, Samokutyaev took part in scientific experiments and station maintenance. He also performed spacewalks. His work helped keep the ISS running and advanced knowledge about living in space.
After his second mission, Samokutyaev retired from active cosmonaut duty. He lived a private life out of the public spotlight. Little is known about his health or activities in recent years.
A First for the ISS: Why This Milestone Matters
The ISS has been home to rotating crews for more than 26 years. Since November 2000, people have lived continuously on the station. That is longer than any other space station in history.
Over those years, 155 expedition crew members have called the ISS home. Many of them are now in their 50s, 60s, or 70s. Samokutyaev’s death is the first among this group. It highlights a new reality: as the ISS ages, so do its former residents.
Deaths of space travelers are not new. Several early astronauts and cosmonauts died before Samokutyaev. But those deaths usually involved people from earlier programs like Apollo, Mir, or the early Space Shuttle missions.
For example, Apollo 11 astronaut Neil Armstrong died in 2012 at age 82. Apollo 17 astronaut Eugene Cernan died in 2017 at age 82. Mir cosmonaut Vladimir Vasyutin died in 2002 at age 50 after a long illness. But none of them were former long-duration ISS residents.
Samokutyaev’s death is the first time a person who lived on the ISS for months has died after returning to Earth. This is significant because the ISS program is still relatively young. Many former crew members are still alive. But as time passes, more will likely follow.
The ISS has hosted people from many countries. Russian cosmonauts, American astronauts, and crew from Japan, Canada, and Europe have all lived there. Samokutyaev was one of the first to leave Earth behind for months at a time. Now he is the first to leave us permanently.
What We Know and Don’t Know About the Cause
Officials have not released the cause of Samokutyaev’s death. Neither Roscosmos nor collectSPACE has provided details. It is not known if he had been ill or if his death was sudden.
This lack of information is common in the early stages of such announcements. Families often ask for privacy. Space agencies tend to wait before releasing medical details. It is possible more information will come out later. But for now, the cause remains unknown.
There is no evidence linking his death to his time in space. Astronauts and cosmonauts undergo regular medical checks before and after missions. But long-term effects of spaceflight are still being studied. Radiation exposure, bone loss, and changes to the heart and eyes are known risks. However, no one has suggested Samokutyaev’s death is related to these factors.
It is also not known if Samokutyaev had any health conditions before his death. He was only 56 years old. That is relatively young compared to many former space travelers. For example, some Apollo astronauts lived into their 80s and 90s. Others died younger from cancer or heart disease.
The lack of details means we must avoid speculation. It is important to respect the family’s privacy and wait for official information.
Roscosmos and the Space Community React
Roscosmos was quick to respond. The agency issued a statement expressing condolences. It described Samokutyaev as a dedicated cosmonaut who contributed to space exploration.
Other space agencies and organizations have not yet commented publicly. But the global space community is small. Many current and former astronauts and cosmonauts likely knew Samokutyaev personally. They may share tributes in the coming days.
Social media posts from space enthusiasts and journalists have already begun. Many note the historic nature of his death. Some express sadness that a man who lived among the stars is now gone.
Samokutyaev’s death also raises questions about how space agencies track the health of former crew members. NASA and Roscosmos have long-term health studies. But these programs are not always public. The death of a former ISS resident may prompt renewed attention to post-mission care.
Looking Ahead: Health and Legacy of Astronauts
Samokutyaev’s death is a milestone, but it will not be the last. As the ISS program continues, more former crew members will reach older ages. Some may develop health problems. Others may die from natural causes.
Space agencies already monitor astronaut health after missions. They track bone density, vision changes, and other effects. But the long-term picture is still unclear. The ISS has only been continuously occupied for 26 years. That is not long enough to see the full range of health outcomes for all former crew members.
NASA runs the Lifetime Surveillance of Astronaut Health program. It tracks the health of former astronauts for their entire lives. Roscosmos has similar programs for cosmonauts. These studies help scientists understand the risks of spaceflight.
Samokutyaev’s death may lead to more public discussion about these programs. It may also remind current astronauts of the risks they face. But it should not be seen as a sign that spaceflight is unusually dangerous. Many astronauts live long, healthy lives after retirement.
For now, the space community remembers Aleksandr Samokutyaev for his service. He spent months in orbit, working in a metal tube 250 miles above Earth. He contributed to science and exploration. And he helped keep the ISS running for those who came after him.
His death is a loss. But his legacy lives on in the station he helped maintain and in the memories of those who knew him.
