Canadian involvement with flights to the Moon go back long beyond @Astro_Jeremy and Artemis II to the Apollo program in the 1960s. Here's my blog entry from 2023 about the Canadians who worked in Apollo. https://t.co/9bJ2KM2Itz

@MarcGarneau led Canada's way into space, not only as our first astronaut but also as a leader of the Canadian Space Agency. As a politician, he showed a high degree of class that is sadly in short supply today.
