A Space Legend Running on Borrowed Time
The International Space Station was never meant to last forever. When it was first assembled in 1998, engineers gave it a proposed lifespan of roughly 15 years. Yet here we are in 2026, and the ISS is still orbiting Earth at 28,000 km/h — older, creakier, and increasingly patched together.
But after nearly three decades in the harshest environment imaginable, the station is showing signs of serious wear. And for Canada, which has contributed some of the most iconic technology aboard the ISS, the question of what happens next hits close to home.
Canada's Role in the Station
Canada's fingerprints are all over the ISS. The Canadian Space Agency contributed the iconic Canadarm2 — a 17-metre robotic arm that has been essential for docking spacecraft, moving equipment, and even performing repairs on the station's exterior. It's been one of the most celebrated pieces of Canadian engineering ever built.
Canadian astronauts have also logged significant time aboard the ISS. Chris Hadfield's 2013 mission — and his viral rendition of Space Oddity — turned the station into a cultural touchstone for a generation of young Canadians interested in science and exploration.
The Cracks Are Real
The problems facing the ISS aren't just metaphorical. The station has experienced air leaks, primarily traced to the Russian Zvezda module, that engineers have been patching for years. Cracks in the hull, aging seals, and increasingly frequent maintenance headaches have raised genuine safety concerns among space agencies.
NASA and its international partners — including the CSA, ESA, JAXA, and Roscosmos — have been candid about the station's declining condition. While the ISS has been cleared to operate until at least 2030, deorbiting it is now firmly on the planning horizon.
What Deorbiting Actually Means
Bringing down a 420,000-kilogram structure from low Earth orbit is no small feat. NASA has contracted SpaceX to build a dedicated deorbit vehicle — essentially a powerful spacecraft that will guide the ISS through a controlled reentry over the ocean, most likely targeting a remote stretch of the Pacific known as Point Nemo, a graveyard for spacecraft.
The process is expected to take years of careful planning, and the controlled reentry is designed to ensure that debris lands safely away from populated areas.
What Replaces It?
The bigger question isn't how the ISS comes down — it's what goes up next. NASA and the CSA are already looking toward commercial space stations as successors. Companies like Axiom Space are developing modular commercial platforms that could eventually serve as replacements, hosting both government astronauts and private missions.
Canada's role in whatever comes next remains to be defined, but the CSA has signalled strong interest in maintaining a presence in low Earth orbit. A next-generation Canadarm is already in development as part of Canada's contribution to the Lunar Gateway — a planned space station in orbit around the Moon.
The End of an Era
For many Canadians who grew up watching Hadfield strum his guitar in zero gravity or followed Canadian science experiments aboard the station, the eventual deorbit of the ISS will feel like the end of a chapter. But it's also the beginning of something new — a more commercially driven, internationally competitive era of human spaceflight.
The ISS gave the world 25-plus years of science, cooperation, and wonder. Canada played no small part in that legacy.
