Re: Ice Oceans Found On Mars
Reminds me of the alien terraforming engines in "Total Recall." Seemed to work largely by plunging gigantic hot elements into buried ice. How this would suddenly create a breathable atmosphere would be an exercise for a screenwriter less butt-ignorant about basic science, but it still looked cool.
I see a big plus here in propellant manufacture on Mars. Cracking water into hydrogen and oxygen just needs energy. The cryogens are hard to work with, but it could still be done.
