Or even on moons. There are several moons that have a non-zero chance of having life on them.

  I'm betting on Europa. Lovely little moon, so many mysteries. Can't wait to see what we uncover from there.

    Heck, even if it ends up being completely lifeless, IMO Europa is still one of the most exciting bodies in the solar system in terms of future potential - Between abundant energy from the Jupiter-Io flux tube, methane fuel from Titan, hydrogen and helium from Jupiter herself, and water from Europa, colonization of the Jupiter system may well be the key to the outer solar system, and potentially even interstellar efforts. More immediately, it could be an essential stepping stone to enable largescale harvesting of the Jupiter Trojans. Even if you'll never see a Jupiter-rise, I for one love the idea of living on Europa.

      I know HN is not one for jokes, but colonizing 'Europa' seems like a hilarious irony in name.

      Isn't the issue with exploring Europa that Jupiter throws a stupid amount of radiation around itself, so spending any time on its surface(or close proximity) is actually a very very bad idea for human life? Sure, beneath the ice you'd be safe as you can be - but you need to get there and then drill through the ice first.
