Ask Allah.
Or read the Mars trilogy

Impossible. Enjoy your horrifically thin atmosphere.

i reckon converting the atmosphere is doable using plants to create oxygen, problem is mars dosent have a magnetic feild, so im not sure it would stay habitable for any leangth of time

- Set up infrastructure for building space stations and equipment out of asteroids
- Have this be almost entirely automated
- Begin having focusing mirrors constructed from Mercurial orbit, several stations so sun is constantly directed onto Mars
- Use Asteroid belt material to construct a massive armada of nitrogen tanker ships to go between Mars and Titan, since Mars seems to have a nitrogen deficiency
- Direct some comets from Kuiper belt to go on atmospheric burn collisions, raising the temperature, causing extra outgassing of gas, and depositing more water on the surface as well as some volatiles
- Begin seeding of bioengineered algae, start widespread human colonization with use of oxygen masks
- Trees and other plants and some insect seeding when oxygen level permits
Tah dahhh.

why terraform Mars or Luna? toss some large-scale habitats into lagrange zones and see about creating a real space-based economy. we just don't have the tech or the "money is bullshit" mindset to properly invest in creating a habitable world of either Mars or Luna

Sigh
Solar winds will eventually disperse it true,
in approximately 100 000 years time

>so im not sure it would stay habitable for any leangth of time
The atmosphere would stay thick enough and relatively protective for tens of millions of years, until we can engineer a solution such as an artificial magnetic field.

There should be a Civ V map for a terraformed mars.

Venus would be better, assuming that you can get rid of the 99% CO2 atmosphere.

>>3619504
>introduce artificial microorganisms that use CO2 and excrete O2 and sugars
>mfw Venus is probably easier to terraform than any other planet at this time

>>3619504
I wonder if that would be an easier problem to solve. Perhaps by some airborne carbon-fixing organism.

>>3619504
We should do both at approximately the same time. I was thinking a planetary-wide sunshield with its opacity set to 100%, freezing out the atmosphere within a couple of decades. Then automated systems scoop 80% of the dry ice into mass drivers and fire them at other places extra gas is needed, such as Mars, Mercury and Luna. The opacity is then dropped to allow a tenuous cold CO2 atmosphere to emerge, with comets dumped onto the eastern surface, speeding the rotation ever so slightly while adding water and seas to the scorched planet. The temperature is increased by letting more sunlight in, and the newly created oceans should begin making carbonaceous rocks. Big problem; plants won't like Venus because of its extremely slow rotation, so it's recommended the sunshield also double as a solar energy collector and a grow light, with a 24 hour period of light and day circulating around the planet, separate from the natural celestial way it would usually be done.

Use von Neumann drones to rocket asteroids into impact trajectory until the surface gravity is closer to 1g. That way you won't even need to melt the poles for water.

>>3619584
You've have to smash something alongside the mass ov Venus into Mars to make that happen. We don't need 1G planet terraforming, 0.376G is fine.

Mass of Earth: 59.7420 × 10^23 kg

Mass of Mars: 6.4191 × 10^23 kg

You need ~53 × 10^23 kg's worth of space rock/ice

>>3619599
>You need ~53 × 10^23 kg's worth of space rock/ice
Estimated total mass of the asteroid belt: 0.03 × 10^23 kg. Not even close man.

>>3619627
It wouldn't even be enough if you smashed all of Jupiters moons into Mars.

>>3619473
Excuse me, but...
>mirrors constructed from Mercurial orbit, several stations so sun is constantly directed onto Mars
...did you mean "concentrated onto Mars"

You don't really need to direct sunlight so Mars gets bathed in it.

Why the fuck do people want Mars to have a 1g gravity field?

It's like finding a convenient deposit of gold right there on the ground and then burying it under a kilometer of rock so you can mine it the same way as other deposits.

>>3619719
To hold an earth-like atmosphere you fucking retard.

>>3619719
amosphere, pressure, and FUCKING BONES AND MUSCLES THAT ATROPHY

I don't even know if I'd terraform it.

I would smash Earth into it.

>>3619726
Huh. I thought we'd explained to everyone and their grand-uncle that you don't need 1g gravity for Mars to keep an atmosphere.

>>3619728
Debatable. There's not enough research into low gravity living to know how big of a problem loss of muscle and bone mass would be on Mars.

In freefall, yes. Not in low gravity.

Even if atrophy becomes a big problem, it can be overcome rather a lot more cheaply and efficiently with regular visits to a centrifuge.

>>3619728
So we inject steroids and more vitamin D

Venus isn't all that hard.
It used to be Earth 2, a long time ago.
Place a sufficiently large shield on front of the planet, the temperatures will dip, the CO2 will become carbonate again, just like it used to be.
Stabilizing it from there on will be a breeze .

>>3619755
Or with some steroids and solar lamps.

What would you do to the excess carbon dioxide? Turn it into usable oxygen and carbon? Pump it into deep geological storage? Ship it to earth and use it in smoke machines?

this was meant as a reply to >>3619772

>>3619755
> Huh. I thought we'd explained to everyone and their grand-uncle that you don't need 1g gravity for Mars to keep an atmosphere.

Oh, Mars just accidentally the whole atmosphere, and all we gotta do is find where he dropped it and give it back, and he swears he won't let it go again?

>>3619820
Yeah, I thought you might be a troll, but decided to give you the benefit of the doubt and think that you just didn't know better.

It would take several million years for a viable atmosphere to "just up and disappear". Was that simple enough for you?

Easy solution, just use heavier air, then it cant leave.

People don't seem to realize how easy it is to smash an asteroid or comet into another object.
If you manage to get it into a close flyby of any massive body, very small difference in velocity and direction result in huge difference afterwards.
Just nudge some Trojan asteroid a bit, it's orbit is already unstable, into a close Jovian flyby, and you can make hugely different targets for it. Maybe you need some additional flybys, but in the end, you could land it anywhere.
Hell, we could do it with todays technology. Some space probe that is essentially ion thrusters and solar panels, it lands on the steroids, and melts the ice and uses it as it's reaction mass.
Depending on the mass of the asteroid, you just continue to add more until you have enough to send it's on the course you want.

>>3619804
The CO2 in Venus atmosphere used to be all Carbonate rock, which gased out after the planet hit a temperature threshold.
Coll the planet down enough, and it will go back being carbonate.

When I played SimEarth, Mars was very difficult. Bombard it with comets to add water, place the atmosphere generators, and if there is too much carbon dioxide, the ice quickly melts, and the atmosphere boils off. Too little, and it remains an icy hell.

Venus is too close to the sun, and Mars it too far away.

>>3619839
I'm thinking long term, what are you, some kind of greedy ignorant boomer?

>>3619882
Long term is long term.
Ten million years is probably enough time for kids to come up with something else in the eveningschool mega-arts&crafts.

By then, it could be we don't even want it anymore and use most of it for some other project. 'Most' because we'd probably want to take a few landmarks and keep them in a museum.
