The photographs taken by the Mars Global Surveyor has scientists excited about the possibility of water on Mars
A new study of photographs
have revealed that bright new deposits observed in gullies on the planet Mars
may prove that water carried sediment through them sometime recently, according to NASA. The U.S. space agency believes it has found "compelling" evidence that liquid water once existed on the surface of Mars.
The recent images were taken by NASA's Mars Global Surveyor space probe. The discovery is important because it might help prove that the Red Planet has an environment that is favorable for living beings. Just trying to find remote signs of liquid water on Mars has been a goal among scientists around the world for a number of years.
The cameras on the Mars Global Surveyor were the first to take images that initially suggested water once flowed on Mars. Scientists then went and searched valleys in search for conclusive evidence of water flow. Just like most reports regarding Mars, there is some debate as to whether or not it really was liquid water -- some scientists claim that liquid carbon dioxide may have cut the gullies.
The findings by researchers were published today in the journal Science – NASA held a news conference to announce the results of the study. The idea that water recently flowed on Mars is another piece of the puzzle that NASA is trying to put together about the still very foreign Red Planet.

starting global warming on a planet that's not even ours? nice. god i love our species, we rock. while we're at it, maybe we should rocket over a moon from jupiter or something and smash it into mars to get more mass to the planet.

Do you feel that there's something immoral in warming a lifeless hunk of rock? Or do you just believe that anything man does is inherently evil?
I thought the Luddites died out long ago...sad to see the philosophy is still alive and well.
