How many more years until humans colonize the planet Mars.?

The U.S. Armed Forces already has a station on Mars.  They also have a base on the moon.  To colonize is a matter of money to fund the project and construct infrastructure on Mars.  I would say within 100 years.

nothing really, since that there was earth 5 billion years b4 humans. so i guess the next 5 billion years( thats when the sun will combust) will be really qiuet!

Still no life is mars,\nLet mars be the beautiful. if life comes there also then it will be earth.

It might be possible although it'll be a lot more expensive than building space settlements and there is also the issue of the lower gravity (we don't know how that will affect the colonists).\n\nIf the gravity issue is solved we might be able to colonise the planet in that timeframe.  The materials needed are mostly there but we'd have to bring a lot of technology and softland it on Mars.  This will include mining technology, fabrication technology and power sources (probably nuclear).\n\nWater could be a problem but we should be able to import it from asteroids and comets so if there isn't any left on Mars it can be obtained from elsewhere without too much trouble.

It generally takes 6-9 months. Please read the book:"The Case for Mars" by Dr. Robert Zubrin, PhD for a down to Earth nuts and bolts scientific discussion of how to put men on Mars, written for the layman. If you have any desire to learn about the future of mankind, this is it.

Yes, we have the technology to do this now.  What's holding us back is the cost, not the tech.\n\nThe trip would be about six months each way using the engines we have now and gravity assists where possible.  The most likely scenario would be to first launch a series of un-manned "provision" ships to land on Mars or perhaps orbit it -- these would contain food, water, and fuel.  Once we had verified that they were safely at their destination, we would launch the manned ship -- which would carry enough provisions for a one-way trip, and upon arrival at Mars re-stock from the earlier unmanned ships and then return to Earth.  \nWe *could* fully provision a ship for a round-trip, but doing so makes the manned craft much larger and expensive, and lacks the backup of additional supplies existing at the destination.\n\nAll of this is already on NASA's drawing boards, though whether it will ever happen or not is completely a matter of $$ :)

Manning Mars is not due to any political reasons like the same for moon during cold war.\nEstablishing human civilization in Mars is very necessary for saving homo sapiens, given earth can face disaster at any time.\nSo not only rich, scientists, people from all spheres of life will be required to go to Mars for humanity to prosper there.\nIt seems another 20-25 years will be taken (based on various articles I have read).

There has been bacteria found on mars before.  I also think that it whould be silly to make one planet only contain life forms.  There is a huge univese and I'm pretty sure that there is.

We are able to today.  Potential cost has been estimated at less than $30 billion...\n\nHey, I have an idea!  Bill Gates can pay for the mission, and then claim Mars all for himself, kinda like the European monarchs did with the Americas!

Not only in the next century. Humans will go to Mars during this century. It seems quite inevitable even if the US decides not to go. China has very ambitious plans for manned spaceflight. They have said they that they will go to the moon and if they accomplish that what´s to stop them from going to Mars? Certainly not a shortage of cash. In only a few decades China will have surpassed even the US as the supreme economic superpower of the world (if the current rate of economic growth can be maintained for that long). Not long ago they surpassed the French economy and are headed to beat the British next. Will the US want to got to sleep under a communist Mars? Could there be another space race under way? If another space race is launched then you can bet the US will do anything they can to beat the chinese. That would include a mannned mission to Mars within this century. A chinese mission to the moon will without a doubt raise some eyebrows in the US congress.

Colonize in the full sense of the world, as in living there for an indefinite period of time, never, at least in those places. Not Mars or the Moon. People will live there for some periods in their life, though, but not "colonize". Too resource-consuming. Moon: 2035. Mars: 2060. Others in our solar system: 2100. Outside of solar system: 2300.\nThat of course if there's no nuclear holocaust.

They are going to try and explore the possibilities of living on Mars in the future due to the fact that they believe the Earth will eventually become unlivable due to the warming of the planet. It probably won't happen in our lifetime but Man will pollute the Earth, the air, and the water so much that we will not be able to survive. The hole in the ozone layer is becoming a major problem.

Just robots sent by NASA. No human has gone to Mars, yet.

In theory it is absolutely possible. In reality, we haven't advanced science to the point where we can inhabit other planets. Currently there are plans to build an elevator that will allow people to enter space without spending months and months training their bodies to withstand the G's when exiting the atmosphere.\n\nThe current step to living on other planets is building a space station large enough to house multiple families, a small city or even refuel a ship. Currently right now travelling to Mars would take years and years. We would need a higher powered engine that uses less fuel and provides more thrust.

I think that we're going to be responsible for putting life on other planets, Mars and the Moon so far.  Because...before there was humans there were tiny things called bacteria.  When we walked on the moon I'm sure we transfered some onto the rocks and it will evolve, when we put the rover on mars, I'm sure there were probably some germs that transfered onto the mars rocks and they will evolve too...it will take lots of time and will not happen in our lifetime, but eventually...it will

20 years? hmmm... by that time we will probably be so overpopulated that scientists will have to think of building communities on other planets to accommodate the ever growing population of earth...

yes, indeed we can . The recent explorers made the discovery of water in ice form can be a good source of supply of organic  chemistry survivng there. While the scientists are reseacrhing  on the survival conditins of us on Mars are aroud 60 pecent if all the conditions are satisfied. In short answer, yes we can not only set foot on mars but also find a way of living on it.
