An atmosphere will take millions of years to be stripped away by the sun's radiation.

As I mentioned in my post, it was strictly a gravitational consideration as Enceladus is much smaller than those and I thought it would be easier to get ice and water with the cost of time. Other commenters, however, have pointed out that although Enceladus' gravity is miniscule, it is deep in Saturn's gravity well which would be an extreme challenge to escape. Would that be a similar case with Europa and Jupiter? I guess Ceres would be the best choice then.

>The Belt asteroids would be a relatively expensive place to get ice, in part because they're closer. It takes a substantial delta-v to reshape their orbits to hit Mars.
What about reshaping their orbits into Mars' orbit so that Mars hits them?

I thought about the Saturn gravity well issue, but wasn't sure how deep in Enceladus was. So I guess any mission to Enceladus would be a one-way trip, at least for the near future. Which ice moons would be easier to get ice from?

Night Sky on Prime. They didn't market it at all. Watched the first season out of the blue and it turned out to be slow but great. Found out right after that it wasn't getting a second season.

I heard metallic hydrogen was a possibility.

I think our first glimpse will be within our own Solar System. Not on Mars, but on one of the ice moons.
