I don’t know about you, but that looks like frozen water to me. If we could get there, we could probably live there. Just drill down into it and hollow it out, and take our oxygen-rich trees and plants with us. The Earth is one of the few rocks in the Solar System that has a molten core, don’t you know.
Water will come in handy for space settlers, someday — broken down to build oxygen for the atmosphere, as well as used for growing food, and showering off. The Gerard K. O’Neill vision of rotating half-glassed (smirk) cylinders to provide simulated 1-G conditions might become home to literally billions someday — assuming a foolproof way is devised of avoiding punctures or worse due to naturally occuring space debris.
I miss Carl Sagan. He was one of the ultimate visionaries of the last century (the 20th century). I read all of his books, and they were very profound. And he died relatively young. What a shame. What a waste of a Clear Spirit.
