Red Mars, Blue Mars, Green Mars, are the three titles in Kim Stanley Robinson's famous sci-fi trilogy. How we colonize and terraform Mars.

While we dream of making Mars look like Earth, we are busy making Earth look like Mars.
Terraform Earth. It's easier, cheaper, faster, with benefits to every human.

Spot on. 🎯 I love science and sci fi. Everything I've learnt tells me our Earth is precious and we had better take care of it.

Why tf is this the standard post every time anything about Mars gets posted?

What we do on earth is completely irrelevant to what we (can) do on Mars.

It's so sad to see that people can't hold two thoughts in their heads simultaneously.

It's always either. Either do something on Mars OR save earth? Why? Do you actually think humanity is unable to do more than one thing at a time? Or do you also advocate for stopping child cancer research until climate change is fixed?

Doubtful.

We could get started, probably make some habitable enclosures, but before we can alter the global atmosphere--a fundamental prerequisite of any other global-scale terraforming we might attempt--there are significant impediments to overcome that are as-yet beyond our capacity.

Namely, the lack of an Ozone layer and a global magnetic field. Both of these serve on our world to protect the atmosphere and the surface from radiation and solar wind. Without them, any gas we pump into the air around Mars is just going to bleed off into space like its first atmosphere did.

Solar powered electromagnets the size of Rhode island at both poles. The ozone comes after.

Significantly smaller space based devices would do the job.

We could deploy a big electromagnetic dipole at the Sun-Mars L1 point.

This would solve the solar wind problem and even reverse the atmosphere loss on its own.

NASA has already done a study on this and it looks promising (ie. Could work)

You need humans in large groups capable of planning and implementing projects with century and beyond timescales. Right now, we're struggling to plan past this next quarter.

TMK no one ever writes about crater sized habitats, or roofing that giant canyon.

The real issue there with those parameters you've given is that of time. As the terraforming itself is the smallest part of it, as it's more to do with ensuring that terraforming is maintained once deployed.

How about terraforming Earth first by solving global warming? If we can’t do that, we don’t stand a chance on Mars.

I have wonderd if we start pelting it with oxygen producing fungi or bacteria we could get a head start in touning it into a habitable environment.

Terraform it to what extent? Enough so that humans could sustain themselves there or 100% Earth-like? The former probably wouldn't take a whole lot, but the latter would be near impossible just because of the size of Mars relative to Earth. Though both would equally take a long time.

I think gravity is a key to keep atmospheric gases trapped but Mars' gravity is much wealer and you can't just pump more gasses into thin atmosphere.

Building domes might be the future colony but they would need to build more reusable rockets, maybe they need to find some water for refueling the rockets.

he couldnt have been serious or is being taken out of context.. thats an attempt to get a denser atmosphere, but there’s no magnetic field to protect it, or humans.

Yeah i might be wrong but it was something about releasing greenhouse gasses it would make mars better ? Idk I’m just rambling.

theres frozen co2 at the poles, throwing a bomb at them would release some but its pointless

It would take millennia to reduce the atmosphere again.

So thickening the atmosphere would definitely work. It wouldn't be stripped immediately.
