How can we go about terraforming mars in the most efficient way possible? Do we nuke it with a really large biological weapon that will cause a similar explosion as the early cambrian to cause an Oxygen ridden atmosphere? How do we go about doing this /sci/

We build tents over craters and areas of land and eventually cover the vast majority of the surface of the planet.

Advantages: No ten thousand year wait time between staring the project and getting significant habitable space, no need to worry about eventual atmospheric erosion, no requirement for beyond-Earth scale industrial capability before the project can even begin

Disadvantages: None it is a better idea than terraforming in every way

More likely you would want to dig downwards quite far until you reach a nice warm area

>> No.9579100

>>9579082
Do you mean a warm depth?

The nice thing about craters is that if you dome them over they essentially produce a very strong heat island/greenhouse effect, so the 12hrs of sunlight Mars gets every day would be enough to keep the interior of the habitat nice and warm. For the first big habitats we'd tent over moderately sized craters near the equator because it's faster, but further north and south we'd probably devote more time to digging deep pits into craters to increase the amount geothermal heat going into the living space.

>> No.9579305

its pretty much impossible and will never be done, and if we did have some magic way to remove or add trillions of tons of mass from an atmosphere then venus would be a much better candidate for terraforming.

I'd start with trying to minimize harmful radiation. You can use terrestrial VLF transmitters [1] and space-based magnetic shields (pic related) [2] to protect the planet from radiation.

What would stop us from building it on the ground.

>> No.9579590

>>9579054
Why would you?

It has very little magnetic field because of its cold core, meaning there's very little protection from solar radiation.

It has a weak gravity relative to Earth, so the essential gases and water vapour would just escape the planet.

This would require a fuck tonne of liquid water and an atmosphere's worth of carbon. The water itself would need an atmosphere to keep from evaporating and a stupid amount of heat to keep from consequently freezing. And, as everyone else has pointed out, radiation shielding would be a serious problem.

None of the problems of terraforming Mars are a case of 'what should we do'; it is always 'how can we complete a task so incomprehensibly massive'. And, when you realise this will take more than a few Earth economies, that becomes 'why'.

No material benefit we can get from terraforming Mars and keeping it that way could ever pay back the cost.

Build domes and orbital cylinders instead.

Might be easier to build it on earth and then ship it up instead of having to build it on Mars or dropping it down onto Mars and then building it there.

Installing a magnetic shield on Mars Actual might be a good long term goal though.

>> No.9579782

>>9579054
A seriously large scaled weapon would need to be used with a very large and expensive delivery system. It doesn't seem like a very practical solution. I think it would require something far more geophysical. Mega nukes could also be disastrous to Martian terrain and cause other unwanted reactions.

>> No.9579783

>>9579771

According to the paper it doesn't have to be particularly big at all. Earth's magnetic field is extremely weak after all. Though the paper is pretty thin and seems to be a summary of a conference talk.

Well it's not like there are 2T dipole magnets just floating around in space. We don't know what effect they would have on the solar wind. Anyway there's no telling it would give us something for nothing. We still would have to count on the atmosphere regenerating or more likely importing CO2 from Venus in some sort of matter stream. This would only give us a pseudo-magnetosphere as a starting point.

Aside from atmosphere problems there is also low gravity.
We don't have conclusive evidence but there is strong doubt that 1/3 g is enough for humans.
And if anyone start talking about centrifuges there is the right place to do that, and it isn't on a planet.

There is no point in colonizing Mars. Builiding a settlement there is dangerous, difficult, and expensive. And there is absoluetely no potential return of investment whatsoever. There are no ressources there, that we don't have on earth (unlike the gas giants or the asteroid belt), using it as an "outpost" for further space travel is barely possible, because it so far away from earth and has a big gravity well (unlike the moon, which is both close and easy to leave). So all in all, we should go there to research it, but building a settlement there is a waste of money.

Generally, human settlements in outer space are only going to happen if 1. we can build large spinning habitats that create an artificial gravity or 2. we can modify our genome so that we can live in reduced gravity without issues (this however would also mean that the space humans could not just come back to earth as they like). Other than that living in space will never happen.
