Canadian Space Agency

Hello from up here! We are the Canadian Space Agency, but many people know us by our shorter name, the CSA. Our main purpose is to lead Canada’s journey into space. This mission has three important parts: we explore the universe, we use science and technology to make life better for people on Earth, and we work to inspire the next generation of Canadians. For many years, Canada’s different space projects were handled by separate groups. Then, on March 1st, 1989, the government of Canada created us to bring all of the country's space-related activities together. By working under one roof, we can better manage big projects, from building robots to training astronauts.

One of our most famous contributions to space exploration is our family of robotic arms. Even before we were officially formed as the CSA, Canadian engineers designed and built the very first Canadarm. This robotic arm was attached to NASA's Space Shuttles and was essential for deploying and capturing satellites. It was like a giant, helpful limb that could work in the vacuum of space. Building on that success, we later developed more advanced robotics for the International Space Station, or ISS. We built Canadarm2, a bigger and smarter arm that is permanently attached to the station. We also created a robotic helper named Dextre, which has two smaller arms and acts like a skilled mechanic. Together, Canadarm2 and Dextre are the station’s construction crew. They build new parts of the station, repair equipment, move supplies, and help astronauts safely perform tasks during their spacewalks.

Of course, robots are only one part of our story. We are also responsible for recruiting and training Canada's astronauts to live and work in orbit. Becoming an astronaut takes years of hard work and study, and our astronauts are prepared for everything from conducting scientific experiments in zero gravity to repairing complex machinery. Many of our astronauts have had the incredible opportunity to serve on the International Space Station. One of our most well-known astronauts is Chris Hadfield, who made history as the first Canadian to be the commander of the ISS. This meant he was in charge of the entire station and its international crew. Space exploration is a global effort, and our astronauts always work as a team with partners from space agencies in the United States, Europe, Russia, and Japan.

While sending astronauts to space is exciting, much of our work focuses on our home planet. We design, build, and operate satellites that constantly orbit Earth, gathering important information. Our RADARSAT satellites are our special eyes in the sky. Unlike regular cameras that need light, these satellites use radar technology, which allows them to see through thick clouds and even in complete darkness. This is very useful for monitoring Canada’s huge and diverse environment. RADARSAT helps us track the movement of sea ice in the Arctic, which is critical for helping ships navigate safely through icy waters. The satellites also watch over our forests and coastlines, and they can spot the signs of natural disasters like floods and forest fires, giving communities time to prepare and respond.

Our work in space is far from over, and we are looking forward to our next giant leap. We are a key partner in an exciting international project called the Lunar Gateway. This will be a new, smaller space station that will orbit the Moon, serving as a base for future lunar missions. Drawing on our decades of robotics experience, we are building a brand-new robotic arm for it called Canadarm3, which will be even smarter and more independent than its predecessors. The return to the Moon is happening very soon, and Canada will be part of it. One of our astronauts, Jeremy Hansen, is scheduled to be on the Artemis II mission. This will be the first time in over 50 years that a crewed spacecraft will fly around the Moon, and a Canadian will be on board, helping to pave the way for future explorations.
