I really expected Victor Glover to be on Artemis 3. Artemis 2 only loops around the Moon while Artemis 3 lands, so it's the more prestigious mission. Still pretty dang awesome to be on the first crewed flight of orion.
Christina Koch has the record of longest spaceflight by a woman and Reid Wiseman got to chose his flight, so it's kinda surprising both neither is on Artemis 3. I don't know anything about the Canadian but this will be their only Artemis seat for a while. NASA seems to be picking one international space agency per mission to donate a seat to. ESA is expected to have a non landing seat on Artemis 3.
Will be pretty funny if Dear Moon flies before this. I do not expect that to happen, but delays are often chaotically unpredictable. Just imagine Youtubers and DJs flying around the Moon while NASA astronauts are stuck waiting on the ground.
