I watched Pandorum last night guys, it's a pretty crazy movie. The thing I liked about it is that even though I'm long done watching the movie, it inspired all sorts of other crazy thoughts in my head. One thought in particular was about new planets. They always say we can't live on Mars because it isn't hospitable to human life. The main thing is that there is no liquid water on the surface. So why can't we just send it there? I think of it like this: we load up a rocket with a big ass thing of water, put some microorganisms in it, send it to Mars, and just let it go. They say that life forms from Earth can't survive on Mars. So why don't we just be the creators of the martian life form? If we send the water, the microorganisms will adapt themselves, they will evolve. Evolution is key, if we try to create Mars-based life forms, I'm sure it's possible. I think it's just as simple as sending water there and letting it play out on its own.
Why not just send the water to Mars?

if it were that easy why not just send water to death valley and make it habitable for human life?

those are not normal human s they may already be able to survive on mars not me ,i have to be in a more hospitable climate i am a wuss
What you are talking about is called terraforming and sending a whole lot of water would be a huge waste. It costs roughly $2000 a pound to send things into space and water is ~10 pounds a gallon. You really wanna spend $20k a gallon to get water to mars?
In reality the plans are more like sending armies of robots to Mars to create huge factories that do nothing but spew out carbon dioxide and create "global warming". This would slowly make it hot enough to bring plants so they could transform the carbon rich atmosphere to an oxygen rich one.
Of course these plans only qualify as "pipe dreams" right now, mostly due to lack of funding.

I had seen that number in the past but after doing some googling it seems I was off by an order of magnitude.
Looks like it was closer to $20k per pound as of 2001, something tells me that number has gone up since then.

*scratches head* Correct me if I'm wrong, but even if you COULD get the water to mars,it would turn to vapor because the atmospheric pressure there isn't enough to sustain it in liquid form on the surface.

Not sure if that would happen before or after it all froze/evaporated depending on where you are.

Water Could Stay Liquid on Mars

From the shoreline of an ancient salty sea to the bottoms of deep, flood-carved channels, Mars is scarred with geological signs that indicate liquid water once flowed on the its surface.
These findings, combined with the discovery of tiny, spherical "blueberries" and the detection of water ice in the planet's polar ice caps, have lead scientists to scour the planet for liquid water in recent years.
The elusive quarry has remained hidden, possibly because it may not exist for more than a fleeting second. Due to Mars' low temperatures and extremely low atmospheric pressure - less than a hundredth that of the Earth- pure water evaporates from ice to gas so quickly that it skips the liquid phase.
But now, new research by a team of scientists at the University of Arkansas suggests that liquid water could persist for some time on Mars, so long as it is salty.
In the lab
Using a planetary environmental chamber - a tank that mimics the atmosphere, temperature, and pressure of other planets - the team exposed various concentrations of briny water to conditions that match Mars' colder, less pressurized environment. Based on these experiments, salty water, it seems, can exist as liquid on Mars.
"It was thought that any liquid on the surface would evaporate almost immediately," Julie Chittenden, a graduate student with the Arkansas Center for Space and Planetary Sciences told SPACE.com. "These brine solutions enable water to stay liquid at colder temperatures. If you expose these brine solutions to cold temperatures, they can exist for a very long period of time."
While pure water freezes at zero degrees Celsius, water mixed with sodium chloride and calcium chloride salts - the two salts used in these experiments - remains liquid down to -21 and -50 degrees Celsius respectively.
Because salty water can exist as liquid at colder temperatures than pure water, it won't make the jump from ice to vapor as quickly, giving it a better chance of existing as liquid on the surface or just below it. Average Martian temperatures range between -125 degrees and 28 degrees Celsius at various latitudes at different times during the day, and the salty test samples stayed liquid within the range.
The key
The key to staying liquid is to stave off evaporation, which occurs when the molecules in a liquid are excited to a state where they bump into each other until they break the liquid's surface and turn into gas. The best way to do prevent evaporation is to keep the molecules from becoming excited, and the best way to do this is to cool the liquid.
For example, a cup of water placed outside in the middle of summer will evaporate much quicker than the same water on a mid-winter day.
"Colder temperatures are what suppress evaporation," Chittenden said. "There's a huge decrease in the evaporation rate the colder it gets."
If liquid water is discovered, there is a good chance it may not sit right at the surface. NASA's Mars rover Opportunity discovered signs that salty liquid once existed only after digging a small trench in the Martian soil.
So, having completed this series of direct atmosphere contact experiments, Chittenden and her colleagues have begun investigating whether ice melts to liquid or jumps straight to gas when placed beneath a layer of simulated Mars soil in the planetary environmental chamber.

It's all a moot point. Obama killed the Mars program. We're not going anywhere .... just pay your taxes.

Due to Mars' unique atmosphere all water placed on the planet will evaporate into the atmosphere. These water molecules are then struck with UV radiation and the hydrogen and oxygen molecules split. The hydrogen molecules travel back into space and the Oxygen molecules get trapped into Mar's "earth/ground/rock". These oxygen molecules oxidize the rocks/earth/ground making it look red....Now you know why we can't just send water to Mars.
Also some water mights still be on mars. It's just trapped in a frozen state and maybe underground deep in the planet too. At mars hight of life the entire planet was covered with 10 inches of water at the most shallowest of ends.
To sum things up basically UV radiation splits water molecules into H and O2, or just O. These oxygen molecules get trapped into the rocks and they hydrogen molecules leaves for space.
To keep water on Mars we'd have to "fix" its atmosphere first before we could send water. Fixing the atmosphere would entail growing plants, raising the CO2 levels, and somehow create a electromagnetic sphere to protect the new atmosphere from UV radiation and other nasty things our sun shoots at us. Mars is geologically dead for the most part so it doesn't have much of a electromagnetic sphere to protect it's land and gaseous molecules. UV radiotion causes molecules to split into their original elements.
To be frank there is a lot of rare astronomical phenomenons going on that makes life on Earth possible. Most planets, lack water, a proper atmosphere, are geologically dead, or just lack convection zones to keep their cores hot. Also most planets lack a molten core to create a electromagnetic sphere of protection.
