text: On today's date in 1981, the Canadarm made its space debut on the Space Shuttle Columbia (STS-2).
  Canada's most famous robotic and technological achievement, the arm – also known as the Shuttle Remote Manipulator System (SRMS) – marked the beginning of Canada's close collaboration with the National Aeronautics and Space Administration (NASA) in human space flight.
  It was, according to the Canadian Space Agency (CSA), "a sterling example of successful international cooperation in space."
  In 2006, the Mint also struck a 14-karat gold Canadarm coin with a face value of $300.
  Struck in .925 per cent silver, this coin has a weight of 31.5 grams, a diameter of 40 millimetres and a mintage of 9,357 pieces.
  That year, the Mint also struck a $300 gold coin featuring Hadfield on his historic spacewalk alongside a laser-enhanced Canadarm. This coin has a weight of 45 grams, a 40-millimetre diameter and a mintage of 1,000 pieces.
  SPACE EXPLORATION COIN
  A $15 pure silver space exploration coin was issued in 2015 as part of the Mint's 10-coin 'Exploring Canada' series.
  Designed by Canadian artist John Mantha, the reverse of the space exploration coin celebrates Canada's role in space with a quintessential image of modern space exploration—two astronauts on a spacewalk outside the space shuttle.
  Orbiting high above the Earth, they are making repairs to the Hubble Telescope with the assistance of the Canadarm.
