It's just a streambed on Mars...

    On the left is a picture from the Curiosity rover of a dry streambed at Gale Crater, Mars.

    On the right is a picture of some curious people in a dry streambed in the Atacama Desert in Chile, Earth.

    Notice anything similar?

    The fact there was water on Mars has been known for a while. We've seen evidence from orbiting crafts and the Opportunity rover landed right in front of a bank of exposed sedimentary bedrock. In 2008, the Phoenix lander saw a substance that had to be frozen water, not frozen carbon dioxide. It's so expected to find signs of water that month after landing, the Mars Science Laboratory rolls across a dry stream on Mars and everybody goes, "Ho hum."

    Not me.

    This is a freakin' dry streambed on Mars!

    You can even see where the running water has had time to undercut the Martian rock. Small round pebbles line the bed. I've hiked this dry streambed.

    I'm blown away.

    I'm blown away by the high quality imagery we can get from such a small device located so far away from Earth.

    And only using a 2 megapixel camera. Proves that megapixel specs aren't everything.

    Agree...I've been saying that for years.

    My 2-year-old 10 MP Canon gets better results than some of the 14 MP cameras out there right now.

    In any case...loving all the Mars digital images!

    The...
    Where there is/was water, there is/was life. This is huge (not hugh). :p

    Pretty much. Of course the Martian lifeforms could have been not much more than microbes. Maybe a bit of a letdown for popular science (easier to get excited by humanoidish Martians), but still significant and exciting.

    If you accept that life had a chance to grab a toehold on Mars back 4+ billion years ago when water ran on the surface, then it's not too large a step to say life could still remain on Mars with water just under the surface, as verified by Phoenix.

    We haven't seen it so far. We might not recognize it if we do. But Curiosity does have an instrument that will detect a wider range of organic molecules in lower concentrations than any previous craft sent to Mars. If there is life, we might find it with the Mars Science Laboratory.

    If we do find traces of microbial life on Mars, no matter how ancient, it will push the odds of current life forms on Europa and Titan WAY up. It appears that both these moons have liquid water oceans below the ice crust, with the heat coming from the rocky cores and tidal friction with their respective planets.
