How much space ice have we collected and examines in space itself? Not much at all. We've sent a probe to a comet, have probes looking at potential ice on mars, everything else is satellites scanning or telescopes. Those look at chemical structure, not crystalline structure.

That said, water RELEASES heat when turning to ice, you know, phase change - http://www.atmo.arizona.edu/students/courselinks/fall16/atmo336s2/lectures/sec1/water.html it releases 80 cal/g to freeze, why is the article (or rather whoever put up the quote at the top) saying it needs to absorb thermal energy to freeze? This is why when you have a freak frost, you water plants and roses, as water freezes it releases energy which insulates plants and protects them from damage. That quote at the top about thermal energy sounds reversed and is not in the linked article, and I have not read the complete article since its behind a paywall, but someone needs to call BS on that statement or clarify it.
