A Canadian astronaut is set to join NASA's Artemis deep space mission around the moon in 2023. The major new public-private space program has the ambitious goal of taking humans back to the lunar surface – including the first woman to land on the moon – and keeping them there. Innovation Minister Navdeep Bains announced Wednesday that the Canadian and American governments have signed a new treaty outlining Canadian participation in the Artemis missions and locking in a seat for a Canadian astronaut on the 2023 launch. The agreement will make Canada the second country in history to have an astronaut travel into deep space and fly around the moon, and also locks in a second flight for a Canadian to the Lunar Gateway station, which is yet to be built.
