NASA photos have showned waters flowing on planet Mars in the past seven years. The photos are taken by the long-orbiting Mars Global Surveyor spacecraft.
Two gullies, each hundreds of metres long, that were photographed in 1999 and 2001 and again in 2004 and 2005, show changes consistent with water flowing down the walls.

”The shapes of these deposits are what you would expect to see if the material were carried by flowing water,” said Michael Malin of Malin Space Science Systems, San Diego. “They have finger-like branches at the downhill end and easily diverted around small obstacles.” Malin is principal investigator for the camera and lead author of a report about the findings published in the journal Science.
The Open University’s Colin Pillinger, who led the British-led Beagle 2 mission to Mars in 2003, said: “Water is a precursor of life. On Earth, wherever there is water there is life. This is really significant. It means we now know where to look for life.”
