>In high school, I played a lot of Dungeons and Dragons. (You may not have guessed this Botanist / Mechanical Engineer was a bit of a nerd in high school, but indeed I was). In the game I played a Cleric. One of the magic spells I could cast was “Create Water”. I always thought it was a really stupid spell, and it never came up. Boy what I wouldn’t give to be able to do that in real life right now.
>There isn’t a lot of water here on Mars. There’s ice at the poles, but they’re too far away. If I want water I’ll have to make it from scratch. Fortunately, I know the recipe: Take hydrogen. Add oxygen. Burn.
>There’s just one catch: Liberating hydrogen from hydrazine is… well… it’s how rockets work. It’s really, really hot. And dangerous. If I do it in an oxygen atmosphere, the heat and newly liberated hydrogen will explode. There’ll be a lot of H2O at the end, but I’ll be too dead to appreciate it.
>With no magnetic field, Mars has no defense against harsh solar radiation. If I were exposed to it, I’d get so much cancer, the cancer would have cancer.
>Resume 08:00 my time tomorrow morning. Tell family I’m fine. Give crew my best. Tell Commander Lewis disco sucks.
>Each crewman had their own laptop. So I have six at my disposal. Rather, I “had” six. I now have five. I thought a laptop would be fine outside. It’s just electronics, right? It’ll keep warm enough to operate in the short term, and it doesn’t need air for anything. It died instantly. The screen went black before I was out of the airlock. Turns out the “L” in “LCD” stands for “Liquid.” I guess it either froze or boiled off. Maybe I’ll post a consumer review. “Brought product to surface of Mars. It stopped working. 0/10.”
