This week marks the twentieth anniversary of a Canadian astronaut’s first space flight and two decades of Canadian human presence in space.

In 1984, with Mission STS-41G aboard Space Shuttle Challenger, Marc Garneau became the first Canadian to fly to space. He returned to space in 1996 for STS-77 aboard Endeavour. In 2000, on STS-97, he flew to the International Space Station, again on Endeavour.
