*cover polar caps with bacteria genetically modified bacteria that can survive the martian surface, lowering albedo and pumping out (some) oxygen
*thanks to higher temperatures and higher air pressure, the southern polar cap (mostly CO2 ice) evaporates, meaning even higher air pressures and more fuel for the bacteria. Water can be provided by crashing some ice asteroids from the belt
*Eventually, the permafrost, underground aquifiers and the northern polar cap melts. Now the temperatures and atmosphere are sufficient to support more efficient plant life, producing oxygen much faster
*in a few centuries, we have a breathable atmosphere (500 milibars, 40% oxygen), but only a few kilometres above the "sea level" (the currently agreed mars zero datum)

Poke scientific holes in my fantasies, /sci/.

Why terraform when mighty voidfaring ships are superior?

Mars is just too far away from the sun for plants to work on solar energy. You'd need orbital mirrors or some shit.

Mars doesn't have an active geology, but its core is still pretty hot. And since it has a much thinner crust than Earth, you could release a fuckton of geothermal energy by just drilling a few holes 50km deep.

>> No.1899694

Without a molten core creating an electromagnetic field, your atmosphere will never withstand solar winds.

Get a bunch of asteroids and lattice them together to make an artificial moon. The moon's gravity will act on Mars' core making it molten. Voila! Electromagnetic field.

Hence, any plants (probably algae) would have to be genetically modified to function on mars. At first, their primary function would be to make the poles darker and lower the albedo, anyway.

>>1899694

You're forgetting mars gets three quarters less solar energy than Earth. The solar wind effect is negligible on any non-negligible atmosphere.

Besides, if we have the power to place a large enough moon into a mars orbit, we don't need to terraform Mars.

Thicker atmosphere, with excess ozone artificially pumped in if necesarry. You don't need a magnetic field that far out from the sun.

Implying that cosmic rays come from the sun...or that gigavolt energy rays notice atmosphere. They aren't a problem on Earth due to the magnetic field.

Mars doesn't have the magnetic field or the gravity to support a breathable atmosphere. The sun would just blast it away.

I've read in a hard sci-fi website covering the terraforming process of planets without a magnetic field, it theoretically could be done with a ring shaped space electromagnet placed in such way it could act as an artificial magnetic field and it would be partially powered by solar power along with a nuclear fusion plant and kept in place by a counterweight and solar sails.

The other solution was to find a rock big and hard enough to hit mars with and hope the impact would start spinning the core. The major issue is that you'd have to wait the surface cool down and it might just create one big crater.

Also some other things ideas was to dump as much space debris on mars to increase its mass but this has been thought as being extremely impractical.

I don't remember the site's name but I think it was something related with project orion or something like that.

Mars gonna be cold as fuck, it'll look more like hoth than earth.
