Understanding how humans survive in space is essential before we go farther
In September 2026, Canadian astronaut Joshua Kutryk will leave Earth's atmosphere for the first time, joining a multinational crew aboard a SpaceX capsule bound for the International Space Station. His mission is not merely a personal milestone — it is one thread in a larger human effort to understand what it takes to live and work beyond our world. As Canada's eighth astronaut to reach the station, Kutryk carries forward a decades-long national commitment to the questions that space forces us to ask about our own endurance and ingenuity.
- Kutryk's original assignment to Boeing's Starliner-1 was quietly redirected when NASA converted that mission to an uncrewed cargo flight, making his path to orbit longer and less certain than planned.
- His September launch aboard SpaceX Crew-13 now places him alongside two NASA astronauts and a Russian cosmonaut, a reminder that the station remains one of humanity's most durable acts of international cooperation.
- The health research and maintenance work awaiting him are not routine housekeeping — they are the unglamorous but essential science that will determine whether humans can survive journeys to the Moon and Mars.
- Fellow Canadian Jeremy Hansen's recent Artemis II lunar flyby has sharpened the sense that Canada is not watching the next era of exploration from the sidelines — it is helping to build it.
- With this the thirteenth SpaceX crew rotation under NASA's Commercial Crew Program, the machinery of regular human access to orbit is now mature enough that the ambition has shifted from reaching the station to reaching beyond it.
Joshua Kutryk will launch to the International Space Station no earlier than mid-September 2026, flying as part of NASA's Crew-13 mission aboard a SpaceX capsule alongside NASA astronauts Jessica Watkins and Luke Delaney and Russian cosmonaut Sergey Teteryatnikov. It will be his first time leaving Earth's atmosphere, and it will make him the eighth Canadian to reach the station and only the fourth to undertake a long-duration stay.
The work ahead of him reflects how orbital research has evolved. Kutryk will oversee Canadian and international science experiments focused on human health and the practical demands of keeping the station operational — investigations designed not just for their own sake, but to answer the questions that will matter most as humanity prepares to return to the Moon and eventually send crews to Mars.
His road to this mission was not straightforward. Recruited by the Canadian Space Agency in 2017 and trained as an astronaut by 2020, Kutryk was originally assigned to Boeing's Starliner-1 before NASA converted that mission to an uncrewed cargo flight late last year, leading to his reassignment to the SpaceX rotation.
The launch comes at a charged moment for Canadian spaceflight. Just weeks earlier, astronaut Jeremy Hansen returned from the Artemis II mission — humanity's first journey to lunar space since Apollo — underscoring that Canada is an active participant in the next chapter of exploration. Kutryk's station mission, though closer to home, feeds directly into that larger ambition: the experiments he conducts and the experience he gains will help lay the foundation for the deeper voyages still to come.
Joshua Kutryk is heading to space this September. The Canadian astronaut will launch aboard a SpaceX capsule bound for the International Space Station, marking his first venture beyond Earth's atmosphere and a significant milestone for Canada's space program.
Kutryk will fly as part of NASA's Crew-13 mission, launching no earlier than mid-September 2026 from Florida alongside two NASA astronauts—Jessica Watkins and Luke Delaney—and Russian cosmonaut Sergey Teteryatnikov. His selection represents a continuation of Canada's sustained presence in human spaceflight. He will become the eighth Canadian astronaut to reach the station and only the fourth to undertake a long-duration mission there, spending months conducting experiments and supporting station operations.
The work awaiting him reflects a broader shift in how space agencies approach orbital research. Kutryk will oversee several international and Canadian science experiments, with particular emphasis on health-related studies and the practical maintenance that keeps the station functioning. These investigations serve a purpose that extends far beyond the station itself: they are designed to answer fundamental questions about how humans can survive and work in the unforgiving environment of space. As nations prepare to return humans to the lunar surface and eventually send crews to Mars, understanding the physiological and operational demands of long-duration spaceflight has become essential.
Kutryk's path to this mission has been methodical. An engineer and former test and fighter pilot, he was recruited by the Canadian Space Agency in 2017 and completed his basic astronaut training in 2020. He was initially assigned to fly on Boeing's Starliner-1, but NASA announced late last year that the mission would transition to an uncrewed cargo flight, opening the door for his reassignment to the SpaceX crew rotation.
This launch arrives at a moment of momentum for Canadian spaceflight. Just weeks earlier, fellow Canadian astronaut Jeremy Hansen returned from the Artemis II lunar flyby mission, where he and three NASA colleagues traveled farther from Earth than any humans in more than fifty years. That mission marked humanity's first return to lunar space since the Apollo program ended in 1972. Unlike Apollo, which focused on brief visits to the surface, the Artemis program is designed to establish a sustained human presence on the Moon and lay the groundwork for eventual Mars exploration.
Kutryk's mission to the station, though in Earth orbit rather than beyond it, serves that larger ambition. The experiments he will conduct and the operational knowledge he will gain contribute directly to the foundation being built for deeper space exploration. This is the thirteenth crew rotation SpaceX has conducted for NASA under the Commercial Crew Program—a partnership that has fundamentally reshaped how the United States and its partners access the station. For Canada, it represents another chapter in a decades-long commitment to human spaceflight and the scientific questions that drive it.

The station is a unique testbed for valuable experiments as humans prepare to set foot on the Moon— Canadian Space Agency
The Hearth Conversation Another angle on the story
Why does it matter that Kutryk is going to the station rather than, say, the Moon like Hansen just did?
Because the station is where we learn how to survive in space for months at a time. Hansen's flyby was extraordinary—it proved we can get there. But living and working there, conducting experiments, maintaining systems—that's the real test. It's the difference between visiting and actually inhabiting.
So these health experiments he'll be doing—what are they really measuring?
How the human body adapts to microgravity over time. Bone density loss, muscle atrophy, fluid shifts, vision changes. We need to know what happens to astronauts on long missions because the Moon trip is weeks, but Mars is months or years. You can't send people there without understanding the cost.
He was supposed to fly on Starliner. Does that change mean anything?
It's a reminder that spaceflight plans shift. Boeing's Starliner had its own challenges, so NASA moved him to SpaceX. It's pragmatic, not dramatic. What matters is that he's going.
Why emphasize that he's the fourth Canadian on a long-duration mission?
Because it's not just about numbers. It's about Canada maintaining a presence in human spaceflight at a time when space exploration is becoming more ambitious and more expensive. Every Canadian who goes to the station strengthens the argument that Canada belongs in these conversations about the Moon and Mars.
The Artemis program keeps coming up in the story. How connected is Kutryk's mission to that?
Directly. The station is the testbed. Everything learned there—about human physiology, about maintaining complex systems, about international cooperation—feeds into Artemis planning. Kutryk isn't going to the Moon, but his work is part of the foundation that makes lunar missions possible.
