When will we see an orbiting colony in space?

We have three people in orbit right now.  Does that count??

Colony you ask.  If we are still around and haven't destroyed our self maybe in 100 years.

Depends what you mean by 'colony'. The International Space Station has crew members spending several months in space.

Never.  It would be the threat of a bad example to capitalism and could interfere with the fossil fuel industry, so it won't happen.

As we write,, components of a rather large, wheel-type, "SPACE HOTEL" is being built---for earth orbit and the plan is to launch and build it by 2025 (I will believe it when I see it)  it looks to be quite legit. A serious project---look it up on YouTube. The 

'Von Braun Space Hotel"

We won't, ever.

But whatever species replaces us in the ecological niche we leave vacant when we disappear into the fossil record, they may see their fellow creatures leave the planet to colonise space. Allow about a hundred million years for evolution to run it's course, and for the fossil fuel reserves to replenish themselves first.

There is no biological, physical or philosophical reason why the Earth's emissaries to the universe have to be human.

Well we do have the ISS

Preceded by the MIR

And who remembers Skylab ?

Back in the late Sixties the guys in Stanford University came up with the idea of The Stanford Torus

It could be done

Nope!!!!!!      

Right now. The ISS is an orbiting space colony. A very small one. 

Assuming that the ISS is really orbiting the Earth,  then there already have a space colony. 

Many in the future
