The next hard part is the dust. Lunar and Martian dust is a huge problem to overcome, and something we don't have to deal with here. Then there's radiation, although there's things we can do to lessen that problem.
I am curious how solar winds would deplete any gasses we vent onto the surface of Mars when it doesn't have a magnetic field to stop or slow any of it. π€
My understanding is that solar winds stripping your atmo is so slow it's a problem on the scale of millions of years
Let me check a source

Okay 21k lb during an earth day does seem like a lot
That's pretty insignificant on a planetary scale, earth loses atmo at TEN TIMES that rate π
I'm just worried it's going to be expensive to keep the atmo replenished
A civilization that can add enough gases to Mars to create close to Earth's atmosphere isn't concerned with minor maintenance like that. A small comet body's worth every hundred years (if even that often), child's play.
