Lol damn. Funny thing though my first thought was does Mars have an atmosphere? Because how would a helicopter even work there?
Ah thanks, plop :) That sounds kinda cool...all that CO2, we could dump a bunch of seeds and water there and let plants create oxygen for us. I know it’s probably a million times more complicated than that though lol. But fun to think about.
Couple big things with Mars that would throw a wrench in that: 1. The atmosphere is so thin that water would "boil" even at its frigid temperature most anywhere, freeze-drying anything organic. (note I say "boil" but it would really sublimate, evaporate directly from the solid to a gas) 2. Removing CO2 and putting O2 into the atmosphere would cause a reverse global warming effect, making it even colder. 3. There's no magnetic field to protect you from the radiation from the sun, so cancer and the like would be a major issue. None are exactly deal-breakers, but they certainly are major challenges to overcome.
What Bogrbon added is indeed correct, although as he stated some of those issues could likely be circumvented or remedied. As for the idea of throwing a bunch of seeds around, besides what Bogrbon said, there are some even more immediate issues, such as: - lack of water. Mars does have ice caps, but they're made of dry -i.e., carbonic - ice. It might have some subsurface "normal" water", but not in sufficient amount, and it would likely freeze on the surface; - while chlorophyllic plants turn CO2 into oxygen, that requires sunlight, which means the process wouldn't be as effective on Mars, and it also doesn't happen at night. At night, trees/plants "breathe" normally, i.e., they take in oxygen and release CO2. So they would asphyxiate in an environment with too much CO2. Also, when I said "slowly", I meant something of the order of 1,000 years. We're gonna need more Elon Musks if we want things to go any faster.
