There's more difference between Alaska and the Equator than the extra 40 minutes Mars introduces, and there don't seem to be significant mental health issues from zero gravity on the ISS. Bone density, sure.

I know a geologist who's still getting super-excited over rocks ten years later.

Wrong. The astronauts do have mental health issues. Google it.

> Across 89 shuttle missions from 1981 to 1998, US astronauts had over 1,800 in-flight medical events; less than 2 percent of these were related to behavioral health, largely stemming from “anxiety and annoyance.”

https://en.wikipedia.org/wiki/Psychological_and_sociological... doesn't mention much that sounds significant (and they're likely the same sort of things that happen on, say, a nuclear submarine).

Any particular Google results you want to steer me towards?
