Curiosity finds evidence of old streambed

The Mars Curiosity rover has come across evidence of ancient flowing streams in several locations.

New photographs returned from the rover show exposed bedrock made up of smaller fragments cemented together, a geological phenomenon known as a sedimentary conglomerate. The size and rounded shape of the gravel indicates that the site would have once been home to a flowing stream of water, just like the streams we see here on the Earth.

Curiosity has been making its way to its first major science destination since landing on the Red Planet back in August. The team behind the rover hope to learn more about Mars' distant past and whether it was once capable of supporting life.

"Scientists theorize that the bedrock was disrupted in the past, giving it the titled angle, most likely via impacts from meteorites."

Why do you feel that way? Oh. Just saying that I would be so excited I don't think I could contain myself! It would be beyond amazing.

i agree with pallidin! i would need to send UM my dry cleaning bill. some kind of fossilized organism... that would make my year. life, so close to home... even though its dead and gone. (i think that makes us better? stroke the human ego guys)

What if we already found some fossils? From here http://www.unexplain...pic=233917&st=0 Ookay guys, I need your opinion. And to be calmed down. Maybe I've found what they reminded me, and it's not geological at all. Here there's the detail of the martian bubbles I posted before And here there's an image of some Nummulites (http://en.wikipedia....wiki/Nummulites) Can you see the cylindrical shape rising from the middle of the circles? To me they look like the same! I'm not saying that these are Nummulites, but maybe they could be some fossils with the same internal structure! Should I drink... [More]

4,5 billion years is a very long time for Mars. There is some probability that once there was some sort of life on it. There is some probability that even today there is some form of life on it. Or are we just looking for human intelligence.

Or are we just looking for human intelligence. I presume, without knowledge, that life on the surface or close sub-surface of Mars would have died a long tine ago(cosmic radiation). However, I see nothing to preclude the existance of, at least, microbial life on Mars much, much deeper, dead or alive.

that's a good question. ^ This old stream bed is on the edge of gale crater. How old is the crater, was it once a lake? I wonder if it would be worth while heading to the lowest point and digging a few feet. There should be no evaporation on Mars, to cold... But the permafrost might be very shallow.. Ice and snow "evaporates", it's called sublimation. That's why icecubes left in a freezer for a long time disappear. Given the low atmospheric pressure on Mars and the high winds, ice would sublime very rapidly. However, your case is still very valid, because if significant sublimation had been oc... [More]

*edit* sorry for the repitition...I missed Waspie's post regarding sublimation. Sweet as. We learn something new every day.. To learn it twice means it wont go away. lol.

WHeres all the new photos? Do keep up DONTEATUS. The new photos were being posted in the appropriately named New Images From Curiosity topic. In the last post in that topic I posted this: As Curiosity sends back more and more images, there is a danger that this tread could become too long. From now on I will be posting new Curiosity images in the Unexplained-Mysteries Space Exploration Gallery (except, of course, where an image warrants a separate topic of its own). The Space Exploration Gallery can be found HERE. I hope that answers your question.
