the dust has about the same particle size as cigarette smoke.

one plan was to cover the polar ice caps in soot/black stuff, that would
melt them releasing water and C02. and other plans to put bigass factories
on there that eat iorn oxide and release oxygen and iorn.

From the little I know about this just about the only valid technology for
starting terraforming a place like Mars would be to start sending small
probes to suitable asteroids and change their orbits so they impact (after
a couple of years at least). Assuming the asteroids contain some water
this may start a process of heating (from dust in the lower atmosphere) or
greenhouse effect and bring conditions closer to what is needed for 'real'
life over a couple of hundred years. I think that this is pure science
fiction for now.

I find it interesting that on the pictures from Mars there seems to be a
lot of dust around. I would have expected there to be very little with
that thin atmosphere and Mars's gravity.
