Which one is easier to terraform? Mars or Venus?

[Anonymous No.12587858]

>>12587856
Probably the smaller one, it has less terra to form.

venus. as the other anon said the martian magnetic field is too weak which is a result of its internal composition, which would be an infinitely more expensive operation. though i wouldnt agree its a pipe dream.

It's easier to release energy from a system than to put energy into a system, so Venus.

That is, if your terraforming takes 1 million years, Venus would be more productive than Mars after that 1 million years. An idealized terraformed Venus would be more productive than an idealized terraformed Mars, and since you are looking for return on investment, Venus it is.

We have to either stop a runaway greenhouse effect, or find a way to start a new one. Maybe if we took all the C02 from venus and put it on Mars we could kill two birds. Does venus have an active magnetic field, though? Because mars' atmosphere would just get stripped away again probably.

Then we tow a large asteroid into orbit around Mars and let the tidal forces fuck with the planet's core making it geologically active again thus generating a new magnetosphere. This is terraforming, not give-up-a-forming.

How do you propose doing that without also liquefying the surface?

[Anonymous No.12592919]

>>12592685
Earth is geologically active and the surface is solid. The problem is that Mars and its moons are a bit too small and ran out of dynamo and need another moon to shake things up. Obviously we should drop some comets on Mars, though.

[Anonymous No.12593037]

>>12592919
>Earth is geologically active and the surface is solid.
I am aware of that. The question still remains: how do want to tidally "massage" Mars to the extent the core reboots without also liquefying the surface? Warm is OK; lava gloop is not.

Dropping comets on Mars will also make it unpleasant on the surface, and while Mars has been pummeled hard in the past, leaving Argyre and Hellas planita with a corresponding Tarsis bulge, even those were not enough to restart the core.

I can agree that Deimos and Phobos are inadequate in keeping tectonics going but that is a later problem.

In my opinion Venus, since all the gas you need is already there and gravity is pretty comfy

>I am aware of that. The question still remains: how do want to tidally "massage" Mars to the extent the core reboots without also liquefying the surface? Warm is OK; lava gloop is not.
The core was once magnetically active with a solid surface. We could adjust the orbits of the three moons to the ideal point where the tidal forces reactivate the core without shredding the surface. We just need the core going with enough of a dynamo effect to increase the magnetosphere past the atmosphere.

The atmosphere on Mars can use all the air and heat it can get. Dropping comets onto Mars would add gas to the atmosphere and heat it up at the same time. We could do that before the surface is extensively inhabited. Also even just skimming comets through the atmosphere would do the same thing without worrying about surface impacts.

Given that the tidal force scales with 1/r^3 I cannot see how you do this without the surface turning into something looking like Io.

Venus.

You basically have to make it a megastructure. Shades covering the entire planet, wait for it to cool down, either harvest the CO2 along the way or cool it all the way down to CO2 freezing and cover it all with Venusian crust rock.
Mars is way harder, you basically need to bombard it with volatile rich asteroids for hundreds of years, and probably use thermonuclear weapons to create an atmosphere and hydrosphere. Mars is probably best left to be para-terraformed, ie. covered with domes. Many craters and canyons are easy to dome over, just like Lunar crater cities will be easy to start the same way.

How exactly could three small asteroid moons possibly cause any major affect on the surface? Aren’t they too small?

Would it not be better just to put it’s moons on a collision course with the planet as that seems like the best way to cause something interesting and even if it doesn’t work it would still be fun to watch and besides Phobos is going to fall onto the surface in the next couple million years anyway as it’s orbit degrades so may as well speed it up.

Solar panels and a big fucking electro magnet at the mars-sun L1 solves the magnetosphere problem. Requires no technology we already don't have. Field strength at mars needs to half a fridge magnet.

Atmosphere can be bulked up with nitrogen compound ice and CO ice from tritan.

[Anonymous No.12594494]

Or use a superconducting magnet, these do not require power after they are energized and the field strength is enormous.

The moon tugs at the oceans. Isn't the tidal forces from the earth's moon the reason why the earth has a molten core and a magnetosphere? That and earth being much bigger than Mars so it cools down slower?

>any major affect on the surface?
We don't want them to have an affect of the surface. We want them to exert tidal forces on the core of mars strong enough to cause enough friction to liquify the core, which would create a dynamo effect, which would generate a magnetosphere.

The earth's moon used to have a liquid core when the moon orbited closer to the earth, but it solidified when the orbit moved further away, and the moon lost its magnetosphere. If we could move the moon back to a lower orbit we could have an atmosphere on the moon, but it would be difficult to move something so large directly. It would be easier to manipulate its orbit through inserting a large asteroid into orbit around earth and using its gravity to change the moon's orbit. Obviously the moon being closer would have an effect on earth. The tides would be more extreme, for example.

Mars also used to have a liquid core, but the planet is much smaller than earth, so cooled faster. With Mars we have a system of three bodies, Mars and its two moons. We could insert an asteroid towed from the asteroid belt into that system to disrupt it, which would change the orbits of the moons. It might be possible to make their orbits more elliptical or lower them so the three moons would exert stronger tidal forces on Mars, strong enough to liquify the core, but I don't know the math, it's just a technique I heard about.

Easy. We'll just install a couple motorized fans onboard.

We'll mitigate this risk by hiring only the most obese of transexuals for our crew. We estimate that the combined gravitational influence of their prodigious girth will be just sufficient to counteract the Sun. Additionally, our marketing team has assured me that this will also provide an appreciable boost to our public relations.
> how will you stay in the solar atmosphere?
We'll anchor ourselves to it using a rope tied to a pail filled with rocks. I believe that our investors will appreciate this solution because of how cost efficient it is.

Simple. We'll just build everything out of wood. No risk of short-circuiting *and* eco-friendly.
