Rover Finds Ancient Streambed On Martian Surface
sighted writes "NASA reports that its Curiosity rover mission has found evidence that a stream once ran vigorously — and for a sustained amount of time — across the area on Mars where the rover is driving. There is, of course, earlier evidence for the presence of water on Mars, but NASA says this evidence, images of rocks containing ancient streambed gravels, is the first of its kind."
There are other fluids than water that can sustain a semicolloidal solution or carry sediments. I assume that scientists now have to figure out what fluid flowed, rather than simply assuming that it had to be water.
Do not look into laser with remaining eye.
... and the Bi-Curiosity Rover
So we spend billions to look at dirt !!
Rover could have been washed away.
Launch, fly 54.6 million kilometers, land, drown. No profit in that.
A feeling of having made the same mistake before: Deja Foobar
It's called soil. Dirt is the stuff stuck on the bottom of your shoes.
Neat.
I see Thoat tracks.

I'm probably way off, but if Earth's core cooled and solidified, wouldn't a majority of our oceans seep below the crust? It seems like magma prevents water from doing this now because it would turn it to steam. Maybe this is what happened with Mars. Both planets are similar in composition, but since Mars is farther from the sun and smaller, Maybe it just cooled quicker and got a head start in the process. That would mean there's a lot more water on Mars than we can observe. We should drill deep into Mars and find out. Life would probably be hanging on down there too
What would be really cool is if Curiosity found some arrows heads along the banks.
Nice job, submitting and subsequently accepting, an article with a link to the NASA article instead of some random blog linking to a multipage ad-heavy website that only vaguely discusses the NASA article. More of this, please.
Love.

It is amazing how few respected armchair scientists can keep at bay legions of puny exogeologists and so-called experts.
It wasn't the Egyptians, Chinese, Africans, and several South American civilizations, nuh uh, no way. What we have here is clearly an ancient martian craft brewery. This particular area must have been where they made their darker ambers and pales by allowing the beer to flow along the natural terrain to give them those distinct natural martian flavors and colors.
How naive am I to get excited at the thought we might happen upon a fossil?

Time to look for fossils?

If they find divots in smooth river rock it could indicate a metabolic process tore into a rock.
Soil is a natural body consisting of layers (soil horizons) that are primarily composed of minerals which differ from their parent materials in their texture, structure, consistency, colour, chemical, biological and other characteristics. It is the unconsolidated or loose covering of fine rock particles that covers the surface of the earth.[1] Soil is the end product of the influence of the climate (temperature, precipitation), relief (slope), organisms (flora and fauna), parent materials (original minerals), temperature, and time. In engineering, soil is referred to as regolith, or loose rock material. Strictly speaking, soil is the depth of regolith that influences and has been influenced by plant roots and may range in depth from centimetres to many metres.
So it doesn't have to contain organics, just has to have been affected by plant roots. Soil is almost always reffered to when talking about stuff to grow things on/in and then on land. You don't talk about the sands of the Sahara as soil after all. Or the soil at the bottom of the sea.
But hey, go right ahead kid, show yourself to be a true dweed and insist on using words by their most strict interpretation, it will warn everyone that you are someone who hasn't any social skills whatsoever. I would warn you to now go try to order soil to fill your kids sandbox but I think it is safe to assume you never will be in that situation.
MMO Quests are like orgasms:
You may solo them, I prefer them in a group.
You have to search through all the photographs, they try to hide them in the flood of images, but one some pictures I can clearly see the tracks of a wheeled vehicle. PROOF there are aliens!

this thread should have thousands comments....but we like to live in our little ball of dirt and look at next snooki shit....plus the religious madness....
This is a perfect example why doing science is morally wrong.
Now when I go to Mapquest and type in "Hottah" they're going to prompt me "Earth or Mars?"
They need to stop exploring mars and put some of those billions into warp drive functionality. I WANT TO MEET GREEN ALIEN WOMEN!!!
Almost looks like a slab of concrete.
Jack of all trades,master of none
Doesn't "round" stones predicting water, just mean they thing it round becase it was caused by erosion caused by water?
What is to stop other kinds of erosion from also making round stones? Would not wind erosion given enough time perhaps do the same thing? Do they not have terrible dust storms on Mars? How are they measuing how long it took to create the erosion?
Anyway it seems a bit of a leap to me.
