Canada’s biggest contributions to space exploration are robotic arms, radar satellites and people. The Canadarm and its successor Canadarm2 built and serviced the International Space Station, the RADARSAT satellites map the planet through cloud and darkness, and in April 2026 Jeremy Hansen became the first Canadian to travel around the Moon. Behind those headlines sits a longer record that surprises many Canadians: the country was only the third in the world to design and build its own satellite. The Canadian Space Agency, created in 1989, coordinates most of this work today.

Alouette and Anik: how a middle power got into orbit early
When Alouette 1 launched on September 29, 1962, only the two superpowers had built satellites. Canada’s reason for going to space was practical. Radio communication across the North depended on the ionosphere, the electrically charged upper layer of the atmosphere, and Canadian scientists wanted to understand it. Alouette studied it from above for a decade, far longer than its designers expected.
A decade later the same logic of geography produced Anik A1, launched in November 1972. A vast country with small, scattered communities needed a cheaper way to deliver telephone and television signals than cables and relay towers. Anik made Canada the first country with a domestic commercial satellite network in geostationary orbit, and it helped bring live television to the Arctic.
Canadarm, Canadarm2 and Dextre: Canada’s robotic signature
If people outside Canada know one Canadian space technology, it is the Canadarm. Built by Spar Aerospace for NASA’s Space Shuttle, it first flew in November 1981 and went on to deploy satellites, move astronauts and repair the Hubble Space Telescope. The Canadian flag on its side became one of the most photographed national symbols in space.
Canadarm2, installed on the International Space Station in April 2001, is larger and more capable. It can move end over end along the station like an inchworm and helped assemble much of the ISS. Dextre, added in 2008, is a two-armed robot that can swap out batteries and other components. Together, they are Canada’s main contribution to the station, and they earned Canadian astronauts their flights to it.
Canadian astronauts who changed the picture
Marc Garneau became the first Canadian in space in October 1984 and later became a federal cabinet minister. Roberta Bondar followed in 1992. Chris Hadfield made the first Canadian spacewalk in 2001 and, in 2013, became the first Canadian to command the ISS; his videos from orbit made him one of the best-known astronauts of his generation. Julie Payette, Robert Thirsk and David Saint-Jacques all logged long stays in orbit.
The biggest recent step came with NASA’s Artemis II mission, which launched on April 1, 2026 and splashed down on April 10. Jeremy Hansen, a former CF-18 pilot from London, Ontario, flew around the Moon with three American crewmates. Canada secured that seat largely through its robotics contribution to NASA’s lunar plans. What has happened to those plans since, including the pause of the Lunar Gateway, is covered in our update on Canada’s space program in 2026.
Eyes on Earth: RADARSAT and Canadian space technology
Canada’s most useful space technology may be the least visible. Radar satellites send out their own microwave signals, so they can see the ground at night and through clouds, which matters in a country with long winters and frequent overcast. RADARSAT-1, launched in 1995, made Canada a world leader in the field. RADARSAT-2 followed in 2007, and the three-satellite RADARSAT Constellation Mission launched in 2019.
The data is used to track sea ice for shipping, map floods and wildfires, watch for illegal fishing and monitor Arctic sovereignty. Solar activity is another growing concern for satellite operators; our explainer on space weather and solar storms covers why.
Science instruments: Canada’s quieter contributions
Canadian instruments fly on many international missions. The James Webb Space Telescope relies on Canada’s Fine Guidance Sensor to point accurately, and the Canadian NIRISS instrument studies the atmospheres of exoplanets. In exchange, Canadian astronomers receive a guaranteed share of Webb’s observing time. A Canadian laser altimeter mapped the asteroid Bennu for NASA’s OSIRIS-REx mission, a Canadian weather station flew on the Phoenix Mars lander in 2008, and a Canadian X-ray spectrometer rides on the Curiosity rover.
This model, in which Canada builds a specialised piece of hardware and receives access or astronaut flights in return, is how a country with a modest space budget stays involved in major missions.
Frequently asked questions
What are Canada’s main contributions to space exploration?
Canada is best known for space robotics (Canadarm, Canadarm2 and Dextre), radar Earth observation (the RADARSAT satellites), science instruments on missions such as the James Webb Space Telescope, and its astronauts, including Jeremy Hansen on the Artemis II lunar flyby in 2026.
What was Canada’s first satellite?
Alouette 1, launched on September 29, 1962. It made Canada the third country, after the Soviet Union and the United States, to design and build its own satellite.
Who was the first Canadian in space?
Marc Garneau, who flew aboard the Space Shuttle Challenger in October 1984. Roberta Bondar became the first Canadian woman in space in 1992.
Has a Canadian been to the Moon?
No Canadian has landed on the Moon, but Jeremy Hansen flew around it on NASA’s Artemis II mission from April 1 to 10, 2026, becoming the first Canadian to travel to lunar distance.
What is the Canadarm used for?
The original Canadarm, used on the Space Shuttle from 1981 to 2011, deployed and captured satellites and moved astronauts. Canadarm2 on the International Space Station helped assemble the station and still captures visiting cargo spacecraft.
