Doesn't matter if mars has water.Gravity on mars is so small that it can't support a dense atmosphere.
even if there was water in liquid form it would simply evaporate in to space.

Mars can be inhabited, but people and plants will have to be inside of bio-domes. That way they can control the atmosphere and gravity. Although I'm not quite sure how they would make an artificial gravity. Plants would have to have some sort of artificial sunlight, due to the distance from the sun and there would have to be a source of heat and water would have to be flow in periodically. I read an article on yahoo about a month ago and NASA is planning to go to the Earths moon again and put a base there. It is supposed to be complete and inhabited by 2021. I don't know what there reason for doing this is, other than maybe to be able to claim it as US property. Your guess is as good as mine.

There can be no water on mars.
Earth is the only planet which is situated in such a way tht it gets just the right amount of sunlight to keep the H2O in liquid state.If it was alittle more near or farther away life would not have existed at all.Thats why there's no life else where cuz apart from earth theres no other planet having the fundemantal building blocks of life namely carbon oxygen nitrogen and hydrogen in the right amount on earth to support life.The gravity is not equal to earth's gravity(9.8) so that we are neither thrown out of the world nor sucked down towards the centre but just enough to be on the surface.And even the sunlight is either too much if we go nearer and too less if we go farther.The position of earth around the sun is also very important as it just takes the right amount of time to complete one revolution.The seasons are depended on the revolution as well.So among all the nine planets it is earth which supported life as it has got all the properties to create it.
The gases and the surface of the planet Mars are not sufficient to create life.If it was we could have encountered some other living entities by now from our neighbouring planet.

Mars could be "terraformed" but it would take hundreds of years to accomplish.
Here are three terraforming methods that have been proposed:
* Large orbital mirrors that will reflect sunlight and heat the Mars surface.
* Greenhouse gas-producing factories to trap solar radiation.
* Smashing ammonia-heavy asteroids into the planet to raise the greenhouse gas level.
NASA is currently working on a solar sail propulsion system that would use large reflective mirrors to harness the sun's radiation to propel spacecraft through space. Another use for these large mirrors would be to place them a couple hundred thousand miles from Mars and use the mirrors to reflect the sun's radiation and heat the Martian surface........Over a period of many years, the rise in temperature would release greenhouse gases, such as chlorofluorocarbons (CFCs), which you can find in your air conditioner or refrigerator.
While we may reach Mars this century, it could take several millennia for the idea of terraforming to be fully realized. It took the Earth billions of years to transform into a planet on which plants and animals could flourish. To transform the Mars landscape into one that resembles Earth is not a simple project. It will take many centuries of human ingenuity and labor to develop a habitable environment and bring life to the cold, dry world of Mars.

You can make oxygen but you will need to build a biodome to hold it. Due to the lack of a protective magnetic field on Mars the solar wind will blow away any atmosphere that you create.
Plants and humans can live in the biodome and will be much more comfortable if it is also pressurised.

Yeah it incredibly is virtually previous information... a minimum of they instructed the certainty this time... NASA has been mendacity to the international for some years approximately what they have got here across, photographed and so on... seek for "platforms on the dark factor of the Moon", you would be surprised at what's being suppressed from the everyday public... And sure i think what ex militia human beings might desire to declare approximately all of it, some are even generals, as antagonistic the lies and the doctored photos the government bully boys have NASA launch.... )O(

We can't even learn to live on this planet as one humankind. Forget living on this planet as a human family. We can not learn to come to common terms with each other on race, gender and creed.
Even if Mars was habitable, lets concentrate on living together on earth first.

Can NASA create a shuttle that doesn't break up on reentry?
