Liquid and rockets is a death sentence.

Liquid and space vessels is worse.

Liquids on reentry is never going to happen.

Water doesn't have to be a liquid, but don't actual spacecraft typically contain liquids during wall of those cases? What do you mean?

You can freeze it before launch, but you'd have to freeze it again before reentry. Not possible, especially if you're talking about lining a craft with it during months of space travel. Water expands when frozen, and contracts when liquid. Metal does the opposite. How would you engineer that?

Why can't it stay liquid?

Didn't think I needed to stoop to that level. Thought I was talking to about obvious things and didn't want to sound patronizing.

Thanks for clearing that up.
