NASA’s Mars Reconnaissance Orbiter (MRO) continually makes high-resolution observations of the surface of Mars. Recent images have revealed that the gullies on the surface are mainly formed by seasonal freezing of carbon dioxide and not liquid water.
A growing bounty of images from NASA's Mars Reconnaissance Orbiter reveals that the timing of new activity in one type of the enigmatic gullies on Mars implicates carbon-dioxide frost, rather than water, as the agent causing fresh flows of sand.
Planetary geologists at Brown University have found a gully fan system on Mars that formed about 1.25 million years ago.
By ALICIA CHANG Associated Press writer LOS ANGELES -- For decades, scientists have scoured Mars in search of water, a basic ingredient for primitive life. But the best clues were always tied to the ancient past when the Red Planet was warmer and wetter.
By JOHN JOHNSON JR. NASA scientists announced Wednesday that they had found evidence that water still flows over the surface of Mars - sporadic gushers that increase the possibility that the Red Planet could harbor some form of life.

By ALICIA CHANG LOS ANGELES - New photographs from space suggest that water occasionally flows on the frigid surface of Mars, raising the tantalizing possibility that the Red Planet is hospitable to life, scientists reported Wednesday.
WASHINGTON, Dec. 6 /PRNewswire/ -- NASA photographs have revealed bright new deposits seen in two gullies on Mars that suggest water carried sediment through them sometime during the past seven years.
Liquid water has flowed on the surface of Mars within the past few years, leaving behind new deposits in gullies monitored by the now-lost Mars Global Surveyor. The results seem to boost the chances that Mars could harbour life.
