Retired astronaut Marc Garneau says he’s eager to learn which Canadian adventurer will make history by being the first to travel to the moon.

The four astronauts on the first crewed deep-space voyage in more than 50 years will be unveiled by NASA and the Canadian Space Agency on Monday. Three are from the United States and one is from Canada.

Scheduled to launch in November 2024, the Artemis II mission will make Canada and the United States the only two nations to have orbited the moon.

While three Space Shuttle flights under his belt, Garneau says he’d be thrilled to return to space, but he’s happy to hand the reins off to another history-making Canadian astronaut.

It’s an unique chance for Canada’s space program, according to Gordon Osinski, head of the Centre for Earth and Space Exploration at Western University in London, Ontario.

The long-term plan for the Artemis mission is to have a man and woman on the moon by 2025 in service of the ultimate goal: eventually dispatching astronauts to Mars.
