I was thinking about this recently. It's kind of amazing to me that we've spent so much effort on Mars, deep space, and even Venus, but the whole time we've had this moon in the solar system that has an ocean waiting to be explored. Admittedly, I'm not that familiar with what exploration of Europa we may have already done, but I don't get the impression that it's gotten much priority. The potential benefit of learning about its ocean seems huge.

P.S. I'm not saying we shouldn't have sent Mars rovers or anything like that. :)

EDIT: Thanks for the kind replies.
