Nothing yet, I want to go to uni for aerospace engineering/nuclear engineering/mechatronics though. Also Mars is my 'thing' on /sci/.

The habitable zone defines where liquid water is sustained on the planet, usually from enough solar radiation. If that solar radiation can be absorbed effectively with less heat radiating into space, either by lowering albedo, making a thick, greenhouse gas atmosphere or reflecting more sunlight onto the planet in question, then you can change the status of whether a planet is in the habitable zone or not. Our limits of a habitable zone is largely defined by Mars being in its current state. What if Jupiter swept up less mass in the early days of the solar system, and where Mars is there was a planet that still maintained its magnetic field from a long time ago, a thick atmosphere and the ability to maintain water as a liquid over much of its surface. Then it would likely redefine the habitable zone.

>Yes it does. It is right near the meteor-belt.
You have to start giving me sources that state Mars' negligible gravity will majorly affect the asteroid belt. It's not in a shooting gallery as you might think, and terraforming Mars will HELP against asteroid impacts as Mars' scale height of the atmosphere will be 2.5 times greater, giving a longer time for the asteroid to disintegrate.

He's right.

Correct, but that's true of any planet given enough solar wind and time. Mars can still hold a habitable atmosphere for hundreds of thousands if not millions of years, and if we have the ability to terraform Mars then we have the ability to construct an artificial planetary magnetic field to shield it from the magnetic field not long after.

Axial tilt won't have much of an effect other than the lack of very noticeable seasons. This can be counteracted by the parasol allowing different levels of sunlight to reach the north and southern hemispheres on a six month timeframe.
