- Mars also can't support a thick enough atmosphere for humans because it doesn't have the same magnetic field as Earth does.
Earth's molten core creates a magnetic field surrounding our planet that helps to protect the atmosphere from the Sun. Harmful rays from the Sun are deflected by the magnetic field, so they don't hit the atmosphere and damage it.
It's thought that Mars once also had a molten core and a magnetic field, but lost it billions of years ago.
The molten core on earth remained molted because of the early impact with a mars like planet, that created the moon
bu bu bu teh asteroidz Surviving Mars is a dope-ass game. Even better with the terraforming pack. It is also a game, and nearly all of the advances that make your continued gameplay possible are so ridiculous that Kim Stanley Robinson would blush. I remember back in the '80s when the idea for "breaking loose the carbon dioxide in the rocks" was proposed. It was proposed that we do this by lobbing something like 7-8x the combined US-Soviet nuclear arsenal at it every year for a hundred years. At the time, it was presented as a "we could feasibly do this if we really really really wanted to" solution that had the added advantage of repurposing the gun we had pointed at our heads (and then building 700 more into our children's children's children's future). Current snark focuses on Elon Musk's idea to melt the poles, not on the idea to release hypothetical calcium carbonate through repeated nuclear explosion; this guy doesn't even acknowledge that such an idea ever happened but lemme tell ya it was published in Analog between 1988 and 1992 and somewhere in New Mexico it's sitting on a shelf. So yeah we can't terraform mars by nuking the shit out of it because of a whole bunch of reasons related to reality. It's good to know that there likely isn't enough CO2 to be had but I mean, we can still always bathe the place in r12 and r134a amirite? The whole "myth...BUSTED" mentality of the skeptosphere mostly serves to validate laughable ideas as plausible ideas, and "It's official: we can't terraform Mars" only gives the nerds a whole new branch of whataboutism to play with.
You can put as many bomb/co2 as you want.. Any atmosphere will be stripped away by the sun due to lack of a magnetic field on Mars . Then, may be the plan is to nuclear bomb it every few hundred year while the Elon Musk's people live there.. I can get behind the idea
There are several idea on how best to shield mars from the solar winds and they aren't all insane. I know Nasa is/was working on a concept that would put a strong magnetic field generator a few thousand miles from the planet between mars and the sun which would create a magnetic shadow. It's theoretical but so was flying at one time.
