Girl planet. Fuck Venus.

Do you expect all of science to hear you and say "OMG HE WAS RIGHT ALL ALONG, WE ARE ALL IDIOTS!"

Venus is too hot.

We can create heat. We cannot create cold.

we are like bros, fuck off

Solletta it carbon dioxide rains out, crash enceladus into into, crash asteroid into equator to spin up and viola.

I was reading about this the other day.
http://en.wikipedia.org/wiki/Terraforming_of_Venus

Seems like the first priority would be to get the temperature down by changing the atmosphere.

"Create" cold?


well, you can transfer heat... (you also cannot really "Create" heat, but you can transfer electromagnetic or gravitational energy into vibrational/rotational/translational energy)


your point remains valid:


there is too much heat in venus' atmosphere to pumpt in anywhere else and live there as a human.


also suluric acid rain, etc.

>>1953416
Not an engineer, so I don't want to fuck my bro. Just Venus.

if mars too cold and venus too hot
what if we mix them together?

>>1953411
You could block the sun with a giant solar sail, or refrigerate the planet and sell the excess heat with lasers.

let's just take heat an move it somewhere else

there is a lot of space

mars is better because one day on mars is about the same as a day on earth.

I would love to terraform Venus, but the fact remains that the technology to do so currently seems to be unavailable. The largest thing of importance in all this is how to effectively siphon away most of it's atmosphere and then put in an artificial planetary magnetic field strong enough to repel a sun 50 million kilometers closer than Earth. I already have an idea of using a big massive 'glass' shield around the planet 100km orbiting it slowly and filtering out a lot of the UV rays and such. but this would require robotic technology that can replicate itself easy from thousands of asteroids and to do this. Ask me the same question around 50 years from now.

You wouldn't need to terraform Venus, it already has the closest atmosphere to Earth anywhere in the Solar system (excepting Earth itself, shut up).

~50km from the surface of Venus the temperature, pressure and gravity are all almost identical to Earth's. Also oxygen is a lifting gas on Venus.

You could take your house, make it air tight, stick an oxygen generator inside it, and then launch it 50km from the surface of Venus and it would float. You'd survive inside just fine.

True, the dilute sulphuric acid in the atmosphere would eventually eat through your house unless you coated it in teflon or something, but you'd probably starve before then anyway.

Mars can suck it. It's too small, has no protection from solar radiation, and the atmosphere doesn't retain heat.

Floating islands on Venus. I'm cool with this.

>>1953654
Holy shit, guys. We need to get onto this.

>>1953681
I'm already well aware of the concept of floating colonies 50km above Venus. The fact is the magnetosphere of Venus is not THAT strong compared to Earth's, Venus DOESN'T have a magnetic field, and is much closer to the sun doesn't really help.

I'd love it if we had some way of moving Venus out to 180 million kilometers away from the sun.

Venus would be way harder to terraform, that's why. In any case, theories about how to do it exist.

With Venus you need to REMOVE a lot of atmosphere to make it livable. With Mars you just need to add it, which is much easier. Smashing comets into Mars would eventually thicken the atmosphere. Once you do that the rest is done for you: with a thicker atmosphere Mars will warm up and water will flow. At that point all you'll need to walk around on the surface is a breath-mask.

The moon, asteroids, and Mars don't have magnetic fields either.

And no you can't add atmosphere to Mars. It would just lose it again. There's a reason it lost it in the first place.

Venus' atmosphere is made of carbon dioxide and sulphuric acid. It's made of Carbon, Oxygen and Hydrogen (and Sulphur). Turn the Oxygen and Hydrogen into water (hyperthermophilic engineered bacteria would be one way) then use the Carbon to build shit.

First think I'd make is a big 100km² Carbon sail to reduce the planet's temperature. You don't need to cover the entire planet to change a climate drastically. You could reduce the planet's temperature within a single lifetime this way.

Mars is further away from the sun, for one.

>Answer: You are absolutely correct. Mars is a small planet, and hence it's gravitational field is not strong enough to permanently hold onto a dense atmosphere, but it is sufficient to hold onto an atmosphere for thousands to millions of years, which is enough for us. Once we terraform Mars, there will be enough of an atmosphere to take of all our needs for generations to come.
>You could reduce the planet's temperature within a single lifetime this way.
Fuck that, MEN! BEGIN THE BOMBARDMENT OF COMETS

Space is the poorest of heat conductors.

BUMP I SAY

Let's say we terraform venus, we terraform the FUCK out of it.

What would happen in regards to politics? Who can rightfully claim the place?
The scientists who terraformed it or the largest contributors to said project?
Free for all, or select few?

What about the recourses and so on, who claims them?

>>1954556
>mfw you still use planets instead of mighty spaceships

>>1954556
The person who has the most control and ability to threaten violence over the planet aka the de-facto government.

>>1954592
Yeah, but who founded it? Who FUNDED it?

I doubt nations wouldn't go crazy over the potentials presented by a completely untapped ecosystem (planet), and thus leave it open for big corporations.

I think such a thing as "earth 2.0" would be a International thing, not a corporate one.

>implying I want to live on a faggot planet that has no moon

>>1954556

There is an existing space treaty which prevents nations from claiming celestial objects as their own.

Which is why we don't own the moon even if we have multiple flags on it.

Mining natural resources from celestial objects is a little more vague.

The US introduced a treaty that would have prevented nations from using said resources for their gain, and that all resources should be spread for all of humanity. However, the fucking soviets refused to sign it.

So it is possibly the at least Russia and China will attempt to control resources. Unless glorious America stops them.

Hopefully the eurofags won't sit on the sidelines while the chinese are stealing all the asteroid monies.

>>1953764
It isn't just mars' size that's the problem, but also the lack of a magnetic field.

And even if we could create earth-like atmospheric pressure (we can't; that article is pure wishful thinking), radiation levels would still be far higher than on earth.

THIS THREAD LACKS MAGNETS

Venus.

A planet once shrouded in mystery. Seen in antiquity as a shining jewel of sacred femininity, revealed by science to be a noxious ball of poison and acid that will smother and destroy anything that gets too close.

JUST LIKE WOMEN, AMIRITE?

>>1955328

lol'd

bump yo

terraforming mars and venus requires the same thing.

collide Titan into mars, or europa into venus
wait circa 1500 years.

and you are considering seriously transporting billions of tons of equipment, personnel and fuel to another planet, I hope you have the technology to propel a celestial body out of orbit or you are FUCKED.

People stop it with the nutcracker maneuvers.

Venus is so hot and acidic, it is difficult to imagine how could it be viable to terraform it. However since it has an atmosphere of mainly CO2, It could be a nice place for orbital manufacturing. We might want to scoop or suck the CO2 into orbit and use the abundant solar energy to convert it into carbon based materials. We'll also get more oxygen than we know what to do with. Perhaps the excess O2 could be handy for ion drives. Ooooh, or maybe the paramagnetic O2 can be used as a magnetically accelerated propellant. That should be more energy efficient.

They said we'd never fly either. Or have hot jelly. They were wrong.
