War of the Worlds microbe style.
Space Ping!
For water to have come and gone it would have to be still there underground or has evaporated into space.
Don't forget the poles.
We may never know since it seems to be the nature of life to eat everything.
Wait,I forgot due to its distance from the sun the temperature there is more than 100 degrees below zero most places at night and impossible for life as we know it to survive.
Why are we determined to waste money on such foolishness.I`m sorry but mankind cannot live there.
Large impacts with meteors could have ejected some water out into space. After the atmosphere was lost the rest would have just boiled off and redeposited at the polar caps.

How frightening. Is that a picture of a Martian alien?
Oh great, some FoxTV producer is probably lurking as we speak, and getting ideas for a reality show...
AmazingSurvivorBrotherApprenticeRaceFactor-Intergalactic:
What happens when the Alien, the Predator, the 'rasta-dudes-from-ID', and 3 Earthlings (or as Greenpeace calls us 'Terra-ists') travel the deserts of the lower Sahara looking for work with only 2 canteens, a pogo stick, and a discarded Dixie Chicks tourbus?
Find out next Friday night at 9! Only on Fox!"
I'm sorry but that is very short sited on your part.
There are several ways that Mars "theoretically" could be made habitable for human life. I don't have the time to relate all of them, but for starters we can thicken the atmosphere by melting the caps or by using comets and slamming them purposefully into the planet bringing water an CO2 to the atmosphere. We can also bioengineer plants to subsist on the current and later thickened atmosphere to produce oxygen.
With current technology we have the basic know how it is merely a matter of scale and developing the engineering to do it.
True, and that makes for having some great fun with the cosmologists.
Intelligent life eats all the matter and energy in the universe and then eats each other: bringing all matter and energy in the universe back together for a "big bang".
Assuming intelligent life can overcome all limits to it's growth it's a blindingly obvious progression.
But it's a theory of creation that's frustratingly of absolutely no use. It explains nothing and gives no useful insight into physical laws.
Even if economic or feasible it still does not change the fact that without heat,life cannot exist.Heat comes from the Sun or the transition of matter from one form to another.On Mars the sun cannot provide adequate heat because of the distance so energy must be expended to create it.
This idea that Mars once had life is just another way that huminists attempt to push creation off the table.
Actually, Carl, it's the other way around. Assuming there was life on Mars a billion or so years ago, it was the greenhouse effect (caused by water vapor and CO2) which would have made the temperature moderate enough to support life. As the water vapor left the atmosphere (probably trapped in permafrost beneath the surface, and at the poles), it was less able to trap the heat, the surface got colder, and away went any life that might have arose.
Why are we determined to waste money on such foolishness. I`m sorry but mankind cannot live there.
It's not foolishness at all. Mankind can indeed live on Mars and must if we are going to survive. President Bush has exactly the right idea; not only will the effort to get to Mars (and back to the Moon) spin-off innumerable technologies that will benefit us here on Earth (you like all that technology that uses transistors? Thank Mercury, Gemini, and Apollo), it also is a worthy goal unto itself, opening up an entirely new realm of human endeavor.
Now THAT is a legacy that will span the ages. When Clinton is a single line in some history book from the year 2500, it will be remembered that Bush not only REALLY opened up space development to private enterprise (Congress just passed the bill last week; Bush will certainly sign it), but also set the national goal on the road to the expansion of humanity throughout the stars.
Who discovered the law of gravity?
Excuse me, but the reason given by most scientists as to why Mars lost its atmosphere is because it lost its magnetic core because the core cooled off. This caused the loss of atmosphere. If this is true, then bringing in water and co2 is not going to help. Mars still does not have a molten core, iron to be exact, that it needs to have magnetism. Without it, we cannot hope to terra form it. This problem would have to be solved first or any atmosphere we bring in will be lost to space just as the original was.
That would just about do it, though, wouldn't it.
I might have missed your point, admittedly.
That is just an old--100 years or so--offhand explanation by a scientist of some kind that has never been questioned because it seems so obvious. But, that is not the only mechanism as any reflection on some of the hugest mag fields in the solar system will disclose.
