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.
Even if you'll never see a Jupiter-rise, I for one love the idea of living on Europa.
