I dont think it'll ever happen. Mars doesnt have a magnetosphere and as a result solar winds would erode away the added gasses and water vapor we manage to add into the system. Even if we were able to manage to get a breathable replenishing atmosphere I imagine the solar radiation would do bad things to us. We'd need like science fiction levels of shielding to keep it livable and we'd need to reach far off sci-fi levels of technology.
I imagine since there is an atmosphere that a pressurized dome city would be less fragile than say a structure on the moon since little holes and leaks wouldnt lead to dramatic explosive decompression. So colonization might be pretty doable but I think a green mars is unlikely.
Dome cities would be much more achievable, but still incredibly difficult unfortunately. It's cool to think it may be feasible in the next generation or two.
My dream is covered canyons with cliff dwellings. But I would settle for a dome+tunnel city.
Yeah, I figured Mars would be an underground territory since that seems to be where any nutrients might be anyway. Trying to form an atmosphere there suitable for life is likely impossible, but cave cities would be theoretically doable.
Although I don't know how I feel about terraforming other planets in general. Humans have destroyed this one so much that I feel like giving us another is akin to not teaching a child not to destroy their stuff. On the other hand, it would just be cool to see what humans have accomplished.
Yes I agree. This terraforming stuff just seems crazy. Frankly the big deal about mars is that it has good access to space but is a real planet. I think it would be much nicer to live on a space station in orbit of the moon or mars rather then on either. At least on a huge space station you can have 1G or 0.5G gravity or something plus build the world you want.
