Mars atmosphere is not that problematic. Melt the poles with nuclear reactors. This creates a CO2 atmosphere. Then use plants to convert CO2 to O2. Now you have a breathable atmosphere, and more heat trapped and thus a more temperate climate. Mars is particularly cool because you can actually terraform it without having to resort to unobtanium. Other planetary bodies and moons locally, not so much.
- politician 15y agoWithout a magnetic field wouldn't this new atmosphere be blown away by the solar wind? If so, it seems a little irresponsible to propose melting the poles. It seems like a better idea to dig deep and build cities under the surface.
- lightcatcher 15y agoI'm no expert, but wouldn't gravity be enough to keep the atmosphere around the planet?
- chc 15y agoI am also no expert, but from what I've read, probably not in the long term. It's commonly believed that Mars used to be more Earth-like, but the deterioration of its magnetic field caused its atmosphere to seep away into space. (Mars' gravity is also just generally weaker than any planet except Mercury.)
