Ok so please explain why people always talk about terraforming mars right but how could we ever get a atmosphere at all if mars doesnt even have a magnetic field, wouldnt any resemblance of a thiccc atmosphere just get blow away by solar winds?

You can generate a stronger field by running a current through planet-spanning loops n shiet. As long as you maintain civilization the atmosphere can be kept at an equilibrium/slowly thicken, since planets exchange particles with the void regularly and the main issue is the loss to gain ratio.

PS you could probably add a complex system of massive satellites to modulate it somehow to be more efficient at retention.

The current atmospheric loss rate on Mars is 100 grams per second. If you assume that loss rate scales linearly with atmospheric pressure and start from a pressure level of 0.25 bar (Mars' current pressure is ~0.01 bar), the loss rate would be 2.5 kilograms per second. Assuming an atmospheric mass of 1/2 that of Earth, it would take ~600,000 years to shed 1% of the atmosphere's mass.

Terraforming is a meme for people whose touch with nature is the local park and the beach, at best. You know, good positive imagery = green, flowery, with cute furry things walking around looking at the camera.
No floods, tornadoes, earthquakes, plagues, frenzied animals, tsetse flies and so on involved.

Swarms of nano bots traversing the solar system, scooping up gases and materials and dumping them on Mars EZPZ

If AI is going to be as advanced as it is claimed then this WILL happen. We would be able to get most of the groundwork by dumber robots traversing the surface and getting the oxygen out of the rust first, as well as lugging CO2 ice towards the equator to melt it. Could eject mass from Phobos and Deimos to push them retrograde until they crash into the surface too.

Smash Phobos snd Deimos into the Martian far northern hemisphere.

I havent figured out how to restart the Martian core without smashing, say, Ceres into it and causing a remelt.

And what is the source of this artificial atmosphere and how does it get to Mars and at what rate?

What is the method of propulsion for these nanobots?

Radiation pressure, controlled by an ability to change the shape of their reflective skin. With advanced AI the swarm could coordinate and figure out the most effficient route to their destination. It wouldn't be quick but it might work.

How does anyone plan to go about generating said magnetic field on Mars without a monumental source of liquid metals to convect?
People always have ideas but they usually are really impractical. Sure, we could create a big zipline across the Atlantic to supply our Redcoats with food from the homeland, but isn't using ships much more practical?
