Prior to terra-forming of Mars, i.e. creating a self-sustaining biosphere out in the open there, all settlements there will be underground or so very well sealed to keep oxygen in and radiation out to be faux-underground. Who in the world wants to go that far to spend the rest of their life in a hole in the ground?
If we can figure out how to put a sustainable society on Mars, why not Earth first? That would be 100x more economical and less risky.
The terra-forming project is the all-time ultimate hubristic engineering project waiting for funding that goes far beyond biblical proportions in both cost and odds against success.
- phs318u 3y agoAgreed. We can't even collectively agree on how or who might pay for the reduction in atmospheric CO2 here on earth (hell, we can't even agree on the need to do so). That cost and impact on the global economy of doing that is a drop in the ocean compared to what would be required to terraform another planet.
- yetihehe 3y ago> hell, we can't even agree on the need to do so I think that is THE main problem. Once we all agree, there will be money put to this and problem will eventually be solved.
- credit_guy 3y ago> and radiation out About that, I wonder if you can't build a local magnetic field to protect you from radiation. With the much lower gravity and very thin atmosphere and no seismic activity, it should be fairly easy to build ultra-tall antenna-like towers, like hundreds of meters tall. You can then put some cables between them, pass some high voltage potential, and maybe you can deflect the cosmic rays enough to keep a certain area more or less radiation free. In that area then you put some pressurized tents, and you don't need to live underground.
