In my immediately previous post, I suggested that very long, conical water
crystallizations of possible Europan origin might survive being within
melting distance of the Sun in part because water crystals in the Sun-facing
side would be very reflective.
The problem with that hyp
Time for a truly weird theory.
For some time now, there's been a conjecture that objects composed mostly of
water hit the Earth's atmosphere several times a day on average. Big,
low-density snowballs, basically.
One of the objections to this hypothesis is that snowballs sho
The surface area of Europa is enormous, and the task of selecting the best
point to begin penetrating the surface shouldn't be left to surveying
technology that couldn't characterize more than a tiny fraction of it.
Perhaps a few short-range rovers might be enough for purposes of check

Personally, I think a Europa rover would be great, not as a scout for a drilling
station, but as an easier, (relatively) low-cost alternative that could be done years
ahead of drilling. A rover could explore the surface near recent impacts, looking for
frozen ocean contents brought naturally to
Maybe I'm just all caught up in the amazing results being done by the Spirit
and Opportunity rovers on Mars, but I am wondering if a mission to Europa
where a probe would dig/drill/melt its way through the ice crust to the
global ocean below would require rovers?
Having rovers on Europa would c
