New Signs That Ancient Mars Was Wet

livescience.com — Mars may have been wet for a billion years longer than previously thought, new water-related opal evidence from NASA's Mars Reconnaissance Orbiter suggests. The findings have implications for the possibility that Mars once supported life.

  • mercury4k, on 10/31/2008, -3/+27*Cue vagina comment*
  • ProfChaosOmega, on 10/31/2008, -1/+19This was due to the Mars Probe Im guessing?
  • inactive, on 10/31/2008, -0/+15Mars does not have a magnetic field as strong as the Earth's magnetic field. The Earth's magnetic field shields it from the ionized particles constantly being ejected from the sun (solar wind). Without a strong magnetic field, Mars' atmosphere has been eroded by these ionized particles chipping away at it for billions of years. The water in the atmosphere would have met the same fate. As the atmosphere thinned, it's ability to retain heat was reduced causing the surface of the planet to cool and the remaining liquid water on Mars to freeze.

    Mars = you sweating
    magnetic field = outer shell of your jacket/windbreaker
    atmosphere = down insulation
    solar wind = normal wind on a cold day

    No outer shell on your jacket and all of your down feathers blow away in the wind. Some of your beads of sweat are carried away on the feathers, and without insulation, if you get cold enough, the rest freeze.
  • mysticalone, on 10/31/2008, -0/+12Dugg for beating me off.
  • groo68, on 10/31/2008, -0/+12The sun's going to expand and engulf earth, not cool down for us to explore mercury.
  • kangarupe, on 10/31/2008, -0/+11There has to be a better way to word that.
  • anagoge, on 10/31/2008, -0/+9Ancient Mars Was Moist With Anticipation Of Growth
  • post3r3r, on 10/31/2008, -0/+6That's what she said
  • grazzier, on 10/31/2008, -0/+6what caused the water on mars to disappear?
  • inactive, on 10/30/2008, -12/+17isn't it just obvious that we came here from there? that religion was created to keep us all stupid? and that the puppet masters have the technology to go somewhere else if they haven't already? and that once the sun has cooled down enough our next stop will be mercury? can't wait for the first human fossil to be unearthed there.. sorry, unmarsed.
  • pinstripewizard, on 10/31/2008, -0/+5"Glowing Neon PBR Sign"

    (sorry, I live in a dry county)
  • SisyphusFragmnt, on 10/31/2008, -0/+4I would make myself easily apparent and not let idiots kill people over me.

    And I would make everyone blue.
  • deathfix, on 10/31/2008, -1/+4Yes, wet tears from laughter.
  • wolfeater2, on 10/31/2008, -0/+3Didnt you know? Kansas doesnt believe in interwebs
  • inactive, on 10/31/2008, -0/+3cool..... so when we are going to exploit mars like we did to the earth..
  • yz101, on 10/31/2008, -0/+3Three miles? You must not know your neighbors well.
  • twiztidsinz, on 10/31/2008, -1/+4To watch the hilarity that ensues?
  • Nightenglow, on 10/31/2008, -0/+3What. The purest blend of hydrogen and helium? THOSE ARE ELEMENTS and by definition elements are as pure as it gets. The global cooling theory is an excuse to pollute some more.
  • jund, on 10/31/2008, -0/+2let hunting alien on mars...captured it and experiment..
  • cheezintern, on 10/31/2008, -0/+2I didn't even know they existed until I moved down south. Apparently a lot of pot is grown in the dry counties around me.
  • inactive, on 10/31/2008, -0/+2wat
  • jhails, on 10/31/2008, -0/+2This will be good news to the ten year old chinese children who will grow up to become the first humans to reach another planet. Cheers and best wishes to you all future martians.
  • pinstripewizard, on 10/31/2008, -0/+2Hell yea, I'm an hour from the nearest liquor store, but I guarantee pot is being grown no more than 3 miles from my house.
  • inactive, on 10/31/2008, -1/+3If you were a god would you stop with creating just one world?
  • wonkavsn, on 10/31/2008, -1/+2This sounds like a job for the beer baron!
  • TheGuruStud, on 10/31/2008, -1/+2***** mass effect. I want Starsiege back!
  • BaoUnit, on 10/31/2008, -3/+4Just to throw this out there, water doesn't necessarily mean there is life. There are life forms on Earth that strive on various forms of carbon, oxygen, hydrogen, etc.
  • Chicken001, on 10/31/2008, -1/+2That's what she said.
  • twiztidsinz, on 10/31/2008, -4/+5Just imagine what kind of stunt the Catholic Church would have to pull in explaining something like humanoid remains or a civilization on Mars.
  • loggedout, on 10/31/2008, -2/+3whore.
  • scottysmith, on 10/31/2008, -0/+1nice, we can all have a nice cool drink when we get there!
  • MattLat, on 10/31/2008, -1/+2Everyone knows that ancient mars was wet. the protheans left a cache of technology there, so it had to support life at some point. just watch out for those damn reapers...
  • SisyphusFragmnt, on 10/31/2008, -0/+1=(
  • cuoops, on 10/31/2008, -0/+1http://mars.jpl.nasa.gov/mro/newsroom/pressrelease ...
  • norcalscan, on 11/01/2008, -0/+1says the guy who is just one hole off and couldn't get vagyrian as a username.
  • pjsk8, on 10/31/2008, -0/+1Great, great song, but WTF does it have to do with this article?

    Nice(?) try though....?
  • wolf49, on 11/14/2008, -0/+1we should just send up a spaceman to look for fossils and bones and ancient houses
  • inactive, on 10/31/2008, -0/+1Your mom.
    =)
  • SisyphusFragmnt, on 10/31/2008, -0/+1Um.. where do babies come from?
  • drexl, on 10/31/2008, -0/+1I already knew this back in '85 after reading the Watchmen....Dr. Manhattan speaks of rivers flowing on Mars while speaking with Laurie Juspeczyk. Duh.
  • tloftxj, on 10/31/2008, -0/+1Is land for sale on Mars, like the Moon?
  • Roland1232, on 10/31/2008, -1/+1Stupid scientists. I HATE THEM SO MUCH!
  • mattwalton56, on 10/31/2008, -1/+1There's a great joke to be found in the title... I just can't find it.
  • aolley, on 10/31/2008, -1/+1since everything in nature follows a wave like function pattern is it not safe to assume that MAYBE the sun is not made of the purest blend of space gas, and somehow it gets slightly warmer and colder, but this small change for the sun is a big change for us, and could even maybe have gotten colder, and mars froze, and is now warming, and mars, and earth, are melting again.?
  • inactive, on 10/31/2008, -0/+0Shhh... It has nothing to do with the article, but they don't know that... Let's just bask in this glorious moment.
