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.

We need a freaking atmosphere Stupid core is solid which means there is no magnetic field

[@twenty-fifth420]

@@Nw-zh1uq Atmosphere is probably the 'easy' part. All you really need to do is blow up the poles as well as harvest all the carbon dioxide in the dust AND find other elements such as nitrogen and hydrogen, likely harvested either from the moon, earth itself or the nearby asteroid belt. The magnetic field part as far as I know is currently 'impossible'. We can technically build two giant magnets and put them near the poles to simulate a magnetic field, but we would need magnets so much more powerful then we have ever made and honestly, we still have to maintain the field with power so it would be practically impossible with the limited energy potential of the planet (our only option is nuclear since solar power is less effective on mars, there is no coal and oil, and fusion right now is still in development.) Possible, but give or take a few centuries.

[@USSGobLin]

It is easy to do theoretically. But we are looking at a time scale of centuries to begin and thousands of years or longer before the first life can be introduced. We would have to also have a way to control solar radiation that reaches Mars to control how fast we can cool the surface. I had this discussion with Dr Freeman Dyson years ago. First you redirect asteroids from the belt and have them collide at specific points based on Mars' trajectory and increasing mass to maintain proper orbit and do so until the entire planet becomes molten to restart the core. Then wait for the surface to cool. Time scales are large and Dr Dyson said it probably would be feasible to start within 500 years based on our current technology.

The idea of the dome cities remind me of Luna (the Moon) from The Formic Wars series. But if we're considering extreme futuristic tech, what would it take to restart Mars' magnetosphere? Would just melting the core work, or would we have to constantly remelt it since a continual strong heat source doesn't exist?

[@anthonylepore516]

No ! Remember in Total Recall, when Arnold puts his hand on that alien computer console, and then the core started to reheat and all of a sudden breathable air circulated saving all the weirdo’s living on mars? So there you go!

[@Hansulf]

@@anthonylepore516 Oh, I thought It just melted the ice caps/undeground gas reservoirs. I guess we could also drill as close to the core as we could as fill holes with radioactive elements to reheat Mars core. I dont know where would we get that radioactive material from though. I think is much easier to just throw the whole Asteroid belt towards Mars 😂😂

[@denalozecon9074]

The Core (movie) had Humans going to the core of Earth to restart Earth's magnetosphere. I don't know what part of that movie was the most unscientific, but it was all impossible with any known technology and even technologies that could be considered plausible within 1000 years...unless Singularity happens and it is an immediate Tech increase to Star Trek levels. Star Trek Federation could do this; not how it is done in The Core, but they do have many other neat technologies. The Core is not good science, but it is fine as entertainment. Anyway with current technology it is just impossible to do this on Mars, even if getting to Mars cost nothing at all for unlimited resources from Earth, even with a budget of $10 trillion also...still not possible. Possible with known physics? Uh yeah I think so? But you would need a civilization that can make 100+ mile Tungsten Drills AND a ridiculous cooling system to keep the drill from melting while drilling through 2000 miles of rock AND then your heat source to melt the core of Mars. All of that is technically possible, but would need technology and a civilization in the Kardishev 1 level at least = millions of times wealthier than Humans on Earth are today.

[@Evan.the.Butler]

@@denalozecon9074 I was thinking more gravitational tech. If we shoot gravity waves from multiple directions towards Mars' core in a way such that they constructively interfere only in Mars' core, we could deposit significant amounts of energy in the core without drilling down. Assuming I'm not missing something, this could melt Mars' core and **maybe** restart a magnetosphere? IDK how plausible that is, but since it would take thousands to millions of years to cool down again, we'd only have to do it infrequently

[@denalozecon9074]

@@Evan.the.Butler I like your idea. There are multiple issues. 1st: While astronomers claim to detect gravity waves, they are not directly detecting gravity, but instead detecting the effect of gravity that corresponds roughly with the time a supernova is detected. So detection of two Neutron Stars smacking together; if you look up the mass of a neutron star then do the inertia calculation of two of them hitting each other at over 500,000 mph? That is a huge huge smack! My mph was a wag but Neutron Stars are supposed to have a surface gravity of 1000 to millions of gravities; if they approach at 100,000 mph from a big distance of millions of miles the gravity effect between them increases exponentially as they get closer...and would accelerate them more the closer they get. 2nd: That is the only event I have heard of that has been detected as a gravity effect; detecting instruments moving a really tiny amount. Really really tiny amount! So an event that big is almost not detectable as a gravity effect. Any attempt with any feasible technology Humans have today to duplicate that...maxes out at inducing a couple asteroids to hit each other at say 150,000 mph as my wag. Even if both asteroids are 100 trillion tons the impact force would create a gravity effect that is omnidirectional and so tiny a mosquito landing on your arm is a larger effect. So a controllable gravity beam or something else Star Trek might talk about is just not at all possible with known technology. 3rd: Just assume for a moment some smart people DO invent a Gravity Beam in this century? Unless it is some really Post Singularity insanity of a technology...it seems likely it would have an effect proportional to the total mass of the device = be useless for reaching through 2000 miles of Mars rock and STILL having a power level that is useful. 4th: All that aside your idea would be very cool as a sci fi tech. However it works it would be usable at one Trillionth the level of what you need to heat Mars core; as either a Tractor Beam like Star Trek or some exotic weapon with a cool name for the Sci Fi story. So my point is your idea is great as an idea. But Unubtanium from The Core is called that for a reason; any neat idea that seems impossible...

[@DreamskyDance]

Yup.. although teraforming Mars sounds cool and has that romantic and poetic achievement for humanity of transforming dead world into a live one... its actually quite wastefull process. Its like those rich people building artificial islands, i mean ok.. nice, but you have bunch of perfectly fine islands allready everywhere. I am not even sure would sulphuric acid rain on the altitudes i read/watched proposed floating stuff would be on Venus, as far as i know on top of the clouds. And that far in the future when humanity is building floating cities on Venus i thing it would not be far fetched that some robotic probes with giant tanks can just circle between Venus and Mars and carry greenhouse gases from one planet to the other, i mean for thousand of years or so but in the end you can end up with terraforming and colonizing two planets instead of one. XD I am also for more focus on the Venus, i hope that sometime soon someone will get enough money to at least test some proof of concept of floating probe on Venus ( for example how they tested solar sails and such ).

I'd think considering all that involves "The Easy Part" ... it'd be far easier to just figure out a way to "borrow" some atmospheric gases from Jupiter. We could filter out exactly what gases we needed and in what quantities. Combined with smashing some comets into Mars ... might be a tad faster. Now we just need to double the density of the core's surface and maybe heat up and restart Mar's magnetic field. Maybe since the core is solidified ... we could just drill down deep enough in the right areas and deposit all of our nuclear waste ... the radiation decay might generate enough heat to do the trick.

So really whether the method is -painting one side of a whole planet dark & one light with an army of devices, -manufacturing an obscene quantity of explosives -or doing the same of either on a smaller space object to make it orbit this moon & sling the moon off its trajectory with some calculated insane math Automated space industry is the first factor to viability; a monumental amount of stuff is needed a monumental distance away so it must be produced there to get scale.

The luminosity of the Sun will steadily increase, resulting in a rise in the solar radiation reaching the Earth.
