Looks like WorldMachine!
Layout Generator, some perlins, a nice radial grad for the mountains or craters, maybe a bit of voronoi... Erode that shit and you have a nice little mars scene. I'm gettin' inspired.
"At most Martian men fancied there might be other men upon Earth, perhaps inferior to themselves and ready to welcome a missionary enterprise. Yet across the gulf of space, minds that are to their minds as theirs are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded Mars with envious eyes, and slowly and surely drew their plans against it."
Time to start a grease fire!
Do you think we have the natural resources available to actually realistically colonize another planet beyond a mere outpost, let alone Mars?
Venus - yes. Mars - no.
plenty of solar and wind power,
has a similar temperatures to that of desert on earth
Higher level of gravity
Possibly usable water
In ∆V terms, Mars is closer than the Moon. From low Earth orbit one-way to Mars is 4.3 km/s + aerobrake capture, deorbit & landing, vs. 5.7 km/s to land on the Moon. While the ubitquitous perchlorates in Martian soil are poisonous, perhaps they're also a useful source for the climate engineering greenhouse gasses.
To be honest, it doesn't make much sense living at the bottom of a deep gravity well if you can avoid it. It's just 4.9 km/s to the orbital vicinity of Ceres, which orbits at the distance where there are plenty of volatiles (Ceres's crust is "wet" olivine, 25% water) but still enough solar energy to spare nuclear fuel requirements. And where there's water there's oxygen and chemical rocket fuel. Once robotic mining/refining/3-D printing is up and running, the only things that must be lifted from Earth's surface are humans, biological samples, and high tech parts that require higher tolerances.
If we don't squander this civilization with runaway greenhouse and fighting over resource scarcity, someday there will be fleets of autonomous solar sails slowly ferrying refined materials to construction locales in the Belt. If He3 is abundant enough out there for fusion, then our descendants will pelt Mars with enough comets to restore an atmosphere long lost to the solar wind.
