A related possibility is not bulk ice, but the sort of water-rich

Phobos), and it's 10-20% fairly-tightly-bound water.

What does 'fairly-tightly-bound' mean? What happens if you heat it in a
solar oven to 1000C?

It's not *that* tightly bound. :-) My understanding is that it's not
likely to come out by itself, but getting most of out won't take a lot of
convincing.
