Ganymede

[All Seeing Eye]

Is Ganymede liveable right now? Apparently it has plenty of water, has an oxygen atmosphere and has it's own magnetosphere as well as being covered by Jupiters.

So what's the problem for colonisation?

 

[USS Excelsior]

It's also freezing cold. Don't think it has any water though, and it only has a thin atmosphere.

It probably would be a good location to set up a base or domed city.

 

[backstept]

the problem is that NASA/ESA etc don't have the funding to research and build the sort of ships and colony building technologies needed to successfully travel to Ganymede, build a colony to support the crew etc . . .

We haven't even been to the moon in decades

I read it has lots of salt water and although the atmosphere is thin it's oxygen, which I would have thought was a positive.

Jupiter's radiation belts would kill people there pretty quickly.

The density of Ganymede's atmosphere is similar to the density of Earth's atmosphere at the height the space shuttle normally orbits.

It's essentially a vacuum. Scientifically interesting but not useful for colonization.

What's keeping you from living there?

[Forbin]

It may have plenty of water, but it's all frozen harder than rock, and the ambient temperature is only slightly above absolute zero. Plus, ya know, there's that total lack of breathable air thing, and the constant sleet of hard radiation.

Maybe a nice vacation spot, but the cost of living is awful high.

Domed cities with nuclear reactor4s for power, issue solved.

 

[Dayton3]

We need Ganymede elsewhere for terraforming.

Moving it toward the sun, burning off the excess water, the putting it into orbit around Mars as a real moon for that world.

Callisto?

Collide with with Mercury to create a Mars sized new world with plenty of water, moved out to orbit Venus.

If we have the power to move planets around with that kind of precision, we don't need planets to live on.

The power to move moons around with that precision isn't rocket science.

It is just a matter of megaengineering and persistence.

You contradicted yourself *and* didn't say anything.

K, let me just beam you there, my warp ship is in the shop right now

You can probably build enough cylinder colonies to house about a 1,000 earth worths of people with just the material from the asteroid belt.

Given a choice, most humans would probably prefer living on the outside of a planet than the inside of a tube.

Science Trivia: There isn't enough material in the asteroid belt to even make a planetoid the size of the moon.

I once started a thread about slamming all the asteroid belt and phobos and deimos into Mars to try and icrease its mass and thus its gravity but I was told the increase would be miniscule.
I say we start bringing asteroids in from the Kupier belt and Oort cloud then to slam into Mars.
