the thing i dont get is:
mars has an iron core like ours. the core had molten iron as well. This created the magnetic field around mars that protected the planet from the
sun's deadly solar flares, radiation, etc.
A long time ago, it stopped spinning, the magnetic field gradually wore away leaving the planet unprotected. The atmosphere was blown off into space.
Without the atmosphere, the water evaporated, plants and animals(if there ever were any) died off, and the wind eroded what was left. The planet
then looked as it does today.
So, by putting plants, animals, and even creating an atmosphere back on mars wouldn't really last long if it worked, because it would just be
destroyed like it was previously. I think the only way would be to jump-start the core to create a new magnetic field. But even this isn't smart,
because the planet is too far away from the sun to keep the core alive due to the cold temps. It was much hotter when the planets were forming. So
in the end, I don't think we can ever truly colonize mars in the way a lot of people think.
