    Humanity’s future is glorious. As we master space travel, we’ll hop from one lifeless world to the next. Life will blossom in our path and the galaxy with shimmer with beautiful Earth-like orbs. Hmmm… maybe. This won’t sound so far fetched if we prove we can do it at least once. If we successfully terraform Mars.

    We already have the technology to bring humans safely to Mars and set up small settlements - or at least could do within a generation. But those settlements will need to be cocooned - shielded against the deadly cold, intense radiation, and the fatal lack of atmospheric pressure. Surely if we want to thrive on Mars – to make it into our second home – these settlers, or their descendants, will need to be able open the airlocks, shed their spacesuits, and step out onto a survivable surface. We’ll need to terraform Mars, as our first step in terraforming the galaxy.

                There's also the problem with lack of gravity on the human body not to mention radiation and how to contain the atmosphere anyways and to make a breathable atmosphere you'd have to do it in the right way or else it would entirely muck up the entire process at any rate in the short-term even if we were to accomplish that long-term we would want effective shielding and that wouldn't happen through passive means you'd want to get in caves that are airlocked that would be the place to start that's all doable there's no point in trying everything the hard way that's for sure and send whatever supplies in drilling robots in whatever ahead of time too and there's a lot that could be accomplished in between times for a lot less money

                      Duh... what a foolish question. No, it's way too small. Gravitation is severely lacking. There is no significant magnetic field. It's moons are just posers. Solar radiation is deadly at the surface. The soils are infused with perchlorates (think bleach!). There is no point in trying. Mars is an exotic shithole. It doesn't have any of the Right Stuff to be like Earth. Maybe we could Marsiform Mars but it's just never going to be anything like Earth regardless of what we do or how hard we do it. I don't believe we could "terraform" any planet except maybe Earth and we haven't thought about doing that yet. We are busy ****iforming Earth right now and, if we survive, we will need to do some global remediation here at home.

                                  Pump the mars core up with uranium waste products, get the core heated up and let nature take effect. Objective is to give mars a chance to potentially start generating a magnetic field to keep solar wind from driving off atmosphere. Then over years transport mass from asteroids etc on to mars to build up its gravity enough (to 60% of earths mass) to more easily hold atmosphere. The more gravity, the less strong the magnetic field needs to be, I think ?🤔

                                        Finally, recognizing how minuscule PEOPLE are in terms of PLANETS, and the TRUE importance of having a magnetic field to preserve an atmosphere. A more limited habitation makes more sense.... IF there is some reason to be there, other than because we can. How do the colonists "make a living"? What is the economic driver of inhabiting Mars? Is there some substance that can be mined for economic gain?

                                          Human beings are so stupid.. Instead of throwing money on colonizing and terraforming mars and idiotic stuff like that, (as much as I love astronomy) why not put that same money and that same effort into SAVING OUR BEAUTIFUL PLANET that we are living on and severely abusing every day...... Instead of looking outwards, lets all start looking inwards, it would be so much more rewarding in the long run.

                                            A couple questions. First, could we not restart Mars' internal heat with a large moon? What would it take? I'm assuming technology capable of moving Ceres or lesser moons of the gas giants here. Get one into low orbit, as low as could be sustained reasonably (and keeping in mind if we can move it, we can probably augment that sustainability). Low enough it tugs at Mars sufficiently, without tearing itself apart, to restart its internal heat. Wouldn't that potentially get us a magnetic field, as well as possibly unlock more gasses from the interior? We'd still need the comet swarm, of course. Just, without a magnetic field, we would risk losing the atmosphere faster than we could add it, I suspect. Some theorize Mars' wet period lasted only a short time, and maybe was due to the massive impacts that created the south hemisphere basis and north hemisphere bulges.

                                            Second question. Why domes? Why not build your cities deep underground, and use light pipe conduits to bring the sunlight in. No risk from micro meteors, and ultimately less expensive with a lower potential for catastrophic failure. You'd still enjoy bright natural sunlight, day and night cycles, and could design the interior so residents really felt more like they were outside, than inside a cave.

                                              Terraforming is when I build stuff that isn't even existent anymore.

                                                Mar's atmosphere is entirely composed of CO2. Adding more CO2 isn't going to increase the green house effect, that is complete garbage science. The issue is having enough gas, or atmospheric mass, to produce the pressure required to sustain life. Water vapor is one of the main drivers of GHG effect on earth. But our atmosphere is composed of Nitrogen for the most part. The higher the pressure the warmer the planet is going to be regardless of the GHG effect. Basic chemistry PV=nRT for ideal gas explains this.


                                                So you would need to introduce enough matter that can be made into a gas into the atmosphere. CO2 can work for this purpose, and the Earth's atmosphere was mostly composed of CO2 when it was first formed billions of years ago. CO2 is also good as it can be plant food and can be converted into O2 for human consumption. If there isn't enough matter in the crust you would need to probably bombard the planet with comets. This would take an incredible amount of resources and time to pull off.

                                                          can not terraform Mars as long as it is in it's current orbit (distance from sun), no matter what we could do it would be it would be too cold to support life. Would have to move Mars to same orbit as Earth.

Or a zillion comets in a mix of iron. It would take 100-1000 years probably but pretty doable if it's all automated. ... Oh, He just said all this while I was writing :-) We need iron to and mass to start the core and have enough gravity to keep any atmosphere at a reasonable pressure. So not just icy comets.

Could we theoretically terraform the moon Titan or some other moon of Jupiter or Saturn to become our next "home" within the Solar System, as an intermediate location, before/& if we can develop a near true interstellar space travel capability?
