    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.

      @@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.

      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.

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.

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.

      @@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...

    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.

      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 think the definition of terraforming is the problem. Mars will probably never have rolling green fields. But if you get the atmosphere to about 5-10% of Earth's, regardless of composition, you allow people to walk with only warm clothing and an oxygen mask. That's a huge improvement.

    Newton's law of universal gravitation: F = G(m1 x m2)/(r x r)
    In this equation F is the force of Gravity, G is a known constant, r is a dimension, but the critical factors are m1 and m2 - the mass of the planet (m1) and the mass of us humans or the mass of the atmosphere (m2). So without planet mass there is not enough gravitational pull to hold the atmosphere and it just drifts away into space.

Even though it is just gas, it has mass and that means you need a way to move it from some other place to Mars to create an atmosphere. And what gasses would you choose? Oxygen of course, but Earth's atmosphere is mostly nitrogen. If you want humans to breathe it, you're going to need a chemically similar composition.
      Then you have to try to get something to grow on Mars, which means you need to do something about the toxic soil and the problem of not enough heat and no water. So, you're building a massive greenhouse.
      While it's possible based on engineering and scientific principles we already know and understand (and use on Earth) it's not feasible at the scale needed to transform a planet. Even a small planet like Mars.

      @@impg8801 it's not that we can't figure it out. It's that it makes it incredibly difficult because of the massive changes needed. There is no shortcut for dredging atmosphere from Venus and flying it to Mars. You have to get it out of the gravity well of the planet. You have to have enough energy to get the cargo to Mars. You have to land it there to release it.

      @Sylwia Kastrau in 200 years of human industry, we have only managed to slightly alter the climate of Earth. To manage the same thing on Mars is another beast entirely. For example, we can burn coal and oil and gas here on Earth because 21% of our atmosphere is oxygen. On Mars, there is no atmospheric oxygen. You can't light a fire at all unless you bring oxygen (or another oxidizer like fluorine) with you in addition to the hydrocarbon you want to burn. That's just to generate energy and thicken the Martian atmosphere, and you need to thicken it because there is barely any atmosphere to begin with. So little in fact that if you were to remove your helmet on Mars, it would be similar to removing it in orbit. It's almost a vacuum.
      So you want to terraform Mars, you need to obtain enough gas to cover a planet, then you need to capture it, then transport it.
      With our current technology, that means chemical rockets. Most of our large rockets are large because most of the weight is fuel to get off the planet. The payloads are tiny by comparison. So that means lots of rockets are needed just to capture gas from somewhere, fly it to Mars and release it.
      The expense of such an operation is prohibitive all on its own but the technical challenges make most people look at it and say 'nevermind'. Those who don't, just don't get why such a thing isn't feasible. Put simply, we need another option. Either resign yourself to the fact that any life on Mars will be in domes or habitats, or come up with some chemical process to magic the gasses from the rocks on Mars. Remembering of course that any reactants or reagents will have to come from Earth, because the building blocks for complex chemistry aren't available on Mars.
      The energy needed to drive such massive processes is not trivial. You're not gonna do it with solar panels.

      Not worth any effort, because while the sun will continue to become brighter until sun will die in 5 billion years, it will increase surface temperature on all planets. Earth will reach 100 degrees Celsius in 1 billion years. If we terraform any planet, we have to chose a planet farther away from the sun than Earth. To our great misfortune, Mars lacks the required magnetic field to protect any future atmosphere from solar wind.

    Comets are great for mining... Could be a win-win.
    One identified comet has the same wealth as all of the earths accessible crust in precious metals. Throwing them onto mars could make them more mine-able.
    The kinetic energy could restart the inner core's magnetic processes as well as give an atmosphere and water. If there was an economic drive behind the comet bombardment process, it may accumulate momentum quickly.
