what about Enceledus, Europa and titan ?

All too far from the Sun, hence too cold. Europa is hot because of volcanic activity driven by tidal forcing, but this also makes it inhospitable.

<p>Now that we are making it to Mars, continuing onward, in an effort for humanity to civilize other planets, not just setting up residential colonies, but to mine minerals and carry on geological and scientific research, which planet or moon has all resources that can be used to sustain life in a controlled biosphere?</p>

<p>And how can the available resources on that body be converted to suit human requirement?</p>

This question appears to be off-topic because it is not about Astronomy and it should belong on [SpaceExploration's StackExchange](http://space.stackexchange.com/)

@Eduardo  Serra : then can you please move it to spaceexploration's stackexchange !!!

It'll be moved if five people agree on it, one of the great things about stack exchange is that it's controlled by it's own community.

I think technology right now doesn't allow for a viable plan but in the future we won't have to depend on any of the planet's resources. Self-sustainable life inside a bio-dome would be the way to go, and any planet where natural disasters like massive storms, earthquakes, active volcanoes and the like are uncommon enough should do the trick.

As the question stands, it would be appropriate for Space, except that the scope is too broad.

The only answer to this that I came to so far is the moon. As it has frozen ice on it's poles. Which means that theoretically electrolysis could be performed to produce energy, powering the biosphere, operating 3D printers to build stuff, or even space crafts which need much less escape velocity on the moon due to 6x less gravity than earth's.

(Asked by: username_0 on 2013-12-29)

Now that we are making it to Mars, continuing onward, in an effort for humanity to civilize other planets, not just setting up residential colonies, but to mine minerals and carry on geological and scientific research, which planet or moon has all resources that can be used to sustain life in a controlled biosphere?

And how can the available resources on that body be converted to suit human requirement?

No known planet except Earth can be colonized by a human civilization. There are at least three serious issues: temperatures at around 300K, an atmosphere of appropirate pressure, and damaging cosmic radiation (low gravity is also a worry for long-term human presence).
