If Europa is the one with conditions they believe to be like early earth, I'm more curious to see if it will develope any further along that line.
Give it a few hundred thousand years.
It's ok, I've got time.
Anyways, I didn't know that about the crater on Mercury, so maybe that is a possibility. Still, I can't see much use for it beyond studying the sun. And no, the gas planets would not work beyond fuel collecting. But, we won't know til we try. (:
Also, CK9, to your post at the start of the page : It was written somewhere, or in a trailer, just not in the intro. I'll try to find it.
