Considering we have the capability how long would it take?

Assuming we have the technology, decades to centuries. There are many issues to consider and it is unlikely that we can address them all to make Mars like Earth. The atmosphere is mostly carbon dioxide and very thin. Simple plants in protective shelters may be able to improve the gas ratio. The temperature is very cold, but we do know how to warm a planet, as we are doing it now on Earth. The radiation could be partially shielded by improving the atmosphere, but we also need to generate a better magnetic field. The gravity is a bit of a problem. I would advocate protective shelters just under the Martian surface rather than full planetary terraforming. It is much easier and more cost effective.

Technically, the surface of Mars can be terraformed, but domes for air density and air pressure would still be required. Mar's simply does not have the mass or the magnetic field to retain a sufficiently thick atmosphere with enough air pressure for human life.

Ok, considering we have the technology, which could be a wait in itself, and then waiting for the project to be internationally approved, designed, and scheduled...well that will take at least 5 years of red tape before the first stone is turned.
Considereing we have the technology, it would then depend on the plans. How big is a dome? Are we talking about planetary overhaul? How long until it can be settled in? Or how long until completely finished?

I heard about that in Discovery Channel. They said it could take about a million years transform the whole atmosphere of the planet. I think it isn't as easy as it seems to be. The surface on Mars receive a lot of deadly radiation from the space and from the Sun. And it would kill every form of life we put there.

As someone else said, it depends on what technology is used. With current tech, I'd say it couldn't be done, but with a mature nanotechnology, it could be done practically overnight, I'd guess a month or so. Exciting prospect, no?

Forever. I do not believe terraforming is possible. It is certainly not possible with our present capabilities.

It really hinges on the technology itself. Also considering it would be our first try it would run long even if we had the technology.

If you're talking about changing the whole planet, forget it. It's too damn cold and we don't have the resources.

more than 100 years.
