I didn't know that there was a way to get an oxygen atmosphere around a planet without life on it, that's really interesting.

Cool, eh? Usually they're Venus-like, but oxygen does seem surprisingly common so it can be on habitable worlds too. Regardless of its prevalence, though, one thing I can say is that if an independent Martian colony is possible, then so is one on Proxima-b.

This is incredible, thanks for doing the work of parsing out the info from the heavy academic papers!

Good to here from you again. I hope you are well. And IMO this system, this galaxy and this universe only gets more surprising.

I want to get back to a more regular schedule this spring. It's been a brutal winter, but I have numerous projects on the go.
