NASA Finds Evidence of Recent Flowing Water on Mars 238
SonicSpike writes to mention that Scientists are claiming that they have evidence of water flowing on Mars within the last five years. From the article: "Subsurface aquifers or melting ground ice were floated as possible sources of the water. One of the springs even appears at a fault line, according to Malin, just as they often do on Earth. The shortness of the gulleys, which seem to flow for but a few hundred yards, might be accounted for by a process similar to a volcano's eruption on Earth, with water instead of magma building up underground, and ice, instead of fire, characterizing the resulting flow."

"Nothing in the images, no matter how cool they are, proves that the flows were wet, or that they were anything more exciting than avalanches of sand and dust," Allan Treiman, a geologist at the Lunar and Planetary Institute in Houston said in an e-mail.

He apparently had seen this stuff in mars rover pictures and predicted it.... guess nasa has finally came to the same conclusion.
I bet they were just more thorough or cautious in their analysis before declaring anything.

"Many scientists believe the gullies were carved by liquid water, although others have argued they are due to avalanches of carbon dioxide gas or rivers of dust," from The New Scientist [newscientist.com].
Also, here [nasa.gov] is the NASA release from their site.

You can see the flow emerges from the side of an impact crater.
The water was most likely locked underground (as expected by the briney moist soil effect the rovers noticed just under the surface)
Its like diggign a hole in the sand at the beach, eventually water will start to seep in.

On a side note [slashdot.org], the HiRISE team [uanews.org] is now posting new large images [arizona.edu] on the HiRISE Website [arizona.edu] every week on Wednesday. (A file size and format warning is needed. The full super high resolution photo of the Opportunity landing site [arizona.edu] is 677 MBytes in JP2 format)
Of course, there are some pics that I wouldn't mind a little more investigation on. I happen to be interested in something I call Gulliver's Golf Ball [usgs.gov], something that looks like a perfect sphere, roughly 200 meters across.

Here's the NASA press release [nasa.gov] with some pictures. There are many more pictures at the Malin Space Science Systems [msss.com] web site (they're the ones that ran the MGS until it was lost a few weeks ago). Also at the same time as the "possible water" press release, they were releasing information on recent cratering -- i.e. craters formed within the last few years. The published article is supposed to be in the Dec. 8 issue of Science [sciencemag.org], but it isn't released yet and you'll probably need a subscription to read it when it is.

Well, yes, but according to the scientists at the press conference all disturbances of the martian soil so far have shown up as darker than the undisturbed soil, not lighter as these images show. Also, the shapes of the light spots are more consistent with those a relatively thick muddy liquid would make than with what you'd see in a landslide. They did allow that yes, these images could be showing some previously unseen dry phenomenon, but that the shapes and color are both indicative of liquid.

Like many other "mysteries" of Mars, domed craters are only mysteries because we assume that electricity is having a limited effect upon the terraforming of Mars. And yet, we can create domed craters with electricity in the laboratory

If you don't mind, I'm going to redirect you to my other recent post on the electrical terraforming of Mars. There is much evidence to support the notion that NASA is ignoring the role that electricity plays on Mars
