Mars has regolith, much like the Moon
Soil is made from formally living things, all the soil, dirt on Earth was once something that was alive
No soil on Mars, none
Remember Mars size, gravity will affect humans and plants, things don't grow, live like they do here
You need, air, pressure, heat, food, shelter and a constant supply
For what return, Mars is not another Earth it is a pretty, cold, desolate rock, a bit larger than our Moon
Mars has no atmosphere not speak of, surface pressure is 1% of Earth, no magnetic shield, localized spots but no core magneto, solar wind is still stripping the remaining atmosphere, surface is bombarded by solar radiation, has some type of water, how much is debatable, how accessible is still up for debate
Mars is doable for a small research outpost, heavily and expensively supported by Earth, the more people there the more the costs, that are subject to review and alteration, cancelation every budget year, by each adminstration, by the public's fading memory
Best if left to private corporations, they reap the rewards, they take the risk, the inevitable disasters
NASA believes the largest payload from orbit to surface has already been reached, and without new technology, larger payloads are not possible
It is doable, but more like the current ISS and much more dangerous and costly
The reality of Mars needs to be kept front and center, not the fantasy of Mars
