Yeah it’ll likely be ESA for Artemis 3 and 5 and JAXA on Artemis 4 for what I’ve heard, with the ESA astronaut on 5 being first non-American on the moon

Here’s my prediction, I’m reasonably confident in this:

CDR: Vic Glover

Orion Pilot: Johnny Kim

HLS Pilot: Jessica Meir

International Mission Specialist: Alexander Gerst

Take this with a grain of salt, but it definitely fits in with rumors I’ve heard from industry people (especially Orion people have told me every flight will have an international on board)

Glover and Meir would be the two that would land
