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."

Flow Means Bi-directional Movement (Score:5, Interesting)
For water to flow, it has to have gotten to the source of the flow first. So, there has to be a mechanism for transport back to the source of the flow. Like rain moves water on Earth back to higher ground. The article offers no speculation on this transport mechanism. I would, of course, suspect evaporation and then dew/frost. But, that would be picked up easily from our probes and even from Earth-based observation.
What am I missing here?

First, look at the electric dust devils of Mars etching the ground black as it moves across:

Now look at the scalloped curled trenches that would result from a pair of Birkeland Currents twisting around one another (as happens in plasma globes). The scalloping and flat bottoms are exactly the same thing you notice on asteroid and cometary craters too

More Martian electric rilles. You've seen the electric dust devils now, so this should not be any great mystery

Domed craters on Mars look precisely like things that have been generated in the lab with electricity

And next, the "collapsed lava tubes"

Rilles exist on the Moon, Earth, Mars and Venus (among other planets), and yet we ascribe different geological mechanisms for nearly all of these. Shouldn't we also consider that one single phenomenon is possibly causing many of them? We know, for instance, that the Grand Canyon was not carved out by the Colorado River because it would have had to plough straight through a gigantic plateau called the Kaibab Upwarp. Interestingly, scientists to this day cannot agree on what caused the Grand Canyon and the fact that entire geological records are missing for that canyon doesn't help either

Remember this? When the rover was mysteriously cleaned? What's so mysterious about electrostatic cleaning?

But my favorite of all time is the mysterious Martian geysers popularized in the news media like here:

The fact that somebody can look at these images (pictured below) and conclude that they are geysers rather than the remnants of electrical strikes

Water on Mars? I'll believe it when astronauts are drinking it.
(!Water - !Life) ? (Score:2, Interesting)
Its a huge flight of fantasy but why can't there theoretically be Sulphur/Silicon based life in say Mars or Venus (or even Mercury) The life we know as it exists on Earth will not be able to survive in those condition but then that is probably the reason we are not living there. If there is actually life in those places then I am sure it is well suited to survive in those "extreme" conditions.
Yeah I know the primary purpose of searching for signs of water is to decide if we can someday colonize that particular planet or its satellites but when someone proclaims something like "No evidence of water therefore no life possible on that Planet", I really wonder about the possible pockets of Life we may be ignoring.
