I was wondering if this might be a good idea. Astronaut has some national semantics attached to it (c.f. cosmonaut), and seems to make less sense when the subject is not actually in space at the time (post #434852), or is in a clearly fictitious universe (post #219592, post #161057, post #148936).
I don't know that an alias or implication is in order for the same reasons as above, but maybe an edit would be good? Space_suit would be more general and more naturally encompass everything on the site.
Anyway I wanted to bounce this off you guys, and get your feedback.
