OK, perhaps a contemporary usage of the word "crest" as opposed to the more traditional heraldic usage, regardless, such symbolism is the heart of heraldry, and the Canadian Space Agency, even though they may not realize it, are actively practicing the spirit of heraldry through their new "crest".
This patch commemorates Canada's first long duration Expedition onboard the International Space Station (ISS). Canadian Space Agency astronaut Dr. Robert Thirsk will live and work in the Station for six months. Robert is an admirer of Pacific Northwest Indigenous art, and is honoured that Bill Helin, a renowned Tsimshian artist has accepted to portray his mission through the use of several of its mythical figures.
