loconet writes "Space.com and JPL are reporting that the Mars Rovers might be on the verge of confirming that large amounts of water once flowed in a region of Mars that has looked curiously dry until now. Such a finding could be comparable to their discovery earlier this year of an ancient shallow sea on the other side of the red planet. Opportunity has found lumpy, odd rock unlike anything its seen to date. The rock concentration seems much rougher than the 'blueberries' found earlier on in the mission. Researchers hope to swing by the rock on the way out of Endurance for further study. 'It could just be one big mass of concretions,' Squyres said. 'I just don't know.' Meanwhile, Spirit, which has now climbed about 10 yards up a hillside, getting above the Gusev plain, found an interesting rock dubbed 'Longhorn'. Both rovers have been exploring more than twice as long as they were designed to last. And even though the Martian winter is at its coldest, engineers are confident that the rovers will continue, despite showing signs of mortality."

Now, I want to know, is this Longhorn rock a symptom of this? [slashdot.org] And if so, is Microsoft giving money to OSDN, or have they gone straight to NASA to participate in "the growing trend of inserting ads more directly into online content" [wired.com]

Yeah, not the most exciting thing but you could send the rover(s) on a long trip to see the remnants and examine stuff along the way.
Checking the remains would provide information for future designs regarding heat shield and parachute technology.

In today's news, there is a description of research into a next generation rover [msn.com] designed to search for life, which will be tested in Chile's Atacama Desert. It is currently designed only to detect DNA-based life as we know it. This may be good enough for Mars, considering the meteorite-carried exchanges of material between Earth and Mars.

Anything that fell from orbit would still end up partly melted, probably fragmented, and showing signs of shock and heating from impact in its mineral structure. This is partly how we identify things like the antarctic Mars rocks as being from Mars.
By contrast, conglomerates like the rock found now are weak and brittle, and wouldn't survive re-entry and impact intact. The other sedimentary minerals found have structures that would also have been changed by something as traumatic as falling from space.
So, minerals on Mars that look like they were formed in water, almost certainly had to have formed in water that was on Mars.

In fact, not that I believe it is as such necessarily, it looks like a fossilized organic somethingoranother. The back end looks something like a frog. Now, this is probably proposterous (it is most likely a volcanic-produced rock), but I sure wouldn't mind being (accidentally) correct.
With the casual way that they mention that they *might* go by and check it out, I certainly hope that they do! Of all of the "rocks" that they have studied so far, I think that this one merits a much less casual reaction. I find their treatment of this discovery a bit odd.

Does it have to be water? (Score:5, Interesting)
Everyone is so excited about the possibility of liquid water on Mars, but has anyone considered that it might be some other type of liquid? Something with different properties that would explain the odd patterns?
This article [nasa.gov] intrigued me, but why is everyone so focused on water? Could the carbon dioxide or some other atmospheric gas be condensing in the cold north to form the odd runoff channels on the rock. This rock faces away from the sun and would therefore be one of Mars' coldest points. Could that be why there is little other than carbon dioxide in the atmosphere? Could wind erosion and perhaps even blast shockwaves from meteorites have been causing the errosive-looking paterns in such an enviroment? With the atmosphere being lighter, wouldn't meteorites hit harder and more frequently than Earth? Finally, can we draw any similarities to our own moon's surface, a place which we know much more about?

After Galileo, battles still to fight (Score:4, Insightful)
I have a feeling that we are still fighting Galileo's battle. A particular strand of Christian thought - medieval Aristotelianism - is still making the running. Aristotle, on no particular evidence, thought that the planets were perfect, lifeless and unchanging - the Schoolmen adopted this as dogma - and scientists and engineers at Nasa are still trying to demonstrate that we occupy what is probably a very ordinary little planet, with a very ordinary set of dominant life forms, against people who think we are unique and very important in this huge universe. You know who you are.
You can still see the lens of Galileo's original telescope, which actually destroyed Aristotle's ideas for anyone with an open mind. I hope one day someone brings the Mars Rovers back to Earth, perhaps along with the Hasselblad left on the Moon. They are signs of a human achievement bigger than the Pyramids, St. Peter's or the Great Wall of China - and an achievement which is under threat from fundamentalists, whether Islamic or Christian. I still find it amazing that the country that has produced insitutions like NASA and Woods Hole has places that mandate the teaching of Creationism, and I find that far more worrying than a survey that suggests that only a minority can find the Pacific.

You could if there was no tilt to its axis of rotation relative to its orbital plane.
Mars, though, tilts about the same as Earth - 25 degrees or so. But its orbital eccentricity has a 19% variance, versus Earth's 2%. The 'Southern Winter' is much longer and colder than the 'Northern Winter,' and the whole planet is colder. The Martian Southern hemisphere experiences much greater temperature variance than any point on Earth.

Here's the likelyest causes.
1. The solar cells accumulate dust and their efficiency reduces.
2. Heating and cooling cycles cause micro-fracturing of the crystals in those solar cells. Their power production decreases for sure, AND the cracks increase how much dust clings to them, so if #1 isn't a problem, it possibly will become one.
3. Flexable materials will outgass some of their lubricants and plasticisers. Plastic parts are particularly vulnerable to multiple combinations of therm
