At time of writing, the world is eagerly awaiting the launch of the Artemis II mission, a planned flight around the moon and back. As is so often the case in astronomy, the facts of this excursion ruin one’s sense of perspective: Although humans landed on the moon itself all the way back in 1969, all of the great many manned flights, both state and commercial, since 1972 have only been as far as Low Earth Orbit. This mission, if successful, will take its crew further away from this planet than any human has ever previously ventured. Though this is a great achievement for humanity as a whole, and although it makes the Earth (with all the various human-made satellites surrounding it) look pathetically small, there is still a nationalist element to be considered here: While lots of countries have a space programme of some description, only the United States of America has ever achieved manned flights of these distances, and every human thus far to travel beyond LEO has been American.

That will change with Artemis II, as one of the crew is Canadian: Colonel Jeremy Hansen, part of the Canadian Space Agency since 2009 and a veteran of the Royal Canadian Air Force. He appeared as flag-bearer as part of the Canadian delegation at the coronation in 2023 and was subsequently awarded the British version of that year’s coronation medal.

Yesterday His Majesty sent an open letter to Hansen specifically concerning the upcoming launch. I have not seen any photograph of a paper version, but the text has been uploaded to the Royal Family website, as well as the Firm’s Twitter account and that of the Canadian Space Agency. The letter says that “as the first Canadian to venture to the Moon, [Hansen] carr[ies] not only the hopes of [his] fellow Canadians and the Commonwealth, but also the aspirations of humanity itself” and also makes references to the Astra Carta programme. It should be clear that Charles here is writing principally in his capacity as King of Canada (as emphasised by the fact that it’s in French as well as English), and indeed the CSA’s Tweeted version explicitly credits him as such, yet as I have remarked before (posts passim ad nauseam) both images show the new illustrations of the British royal arms with the Tudor crown.

Arms of the Canadian Space Agency, granted in 1991

All the photographs of Hansen in his space suit show St Edward’s crown featured prominently on his name badge, suggesting that the “Trudea crown” has not yet been rolled out to that extent. This flight could therefore represent the furthest that anyone wearing an official representation of said crown has ever travelled, which ought to be a good story for the heraldic record book.
