TheOther: Cabron would be more interesting.
occamswrist: Now nasa can carbon date mars.I winder what age it will be?
dittybopper: NASA's earthshaking Mars discovery is finding Han Solo frozen in carbonite. Well, actually, just carbonThey found Han Solo frozen in carbon? That is big news.
That Reilly Monster: FTFA: Even with carbon and water, life needs other chemicals, such as sulfur, oxygen, phosphorous and nitrogen, to form and evolve.Statements like this irk me. Would it be too much to ask for "life as we understand it needs other chemicals..."?
Maktaka: This is a shiatty headline and article, some careful reading is required to get any value out of it. They found carbon COMPOUNDS, specifically organic ones. They're not inherently indicative of life, but they are a requirement for life to exist which means it's one more item that Mars has which would allow for life to exist there.

Would it be too much to ask for "life as we understand it needs other chemicals..."?Bothered me as well. Should have read "Even with carbon and water, life on Earth needs yaddayaddayadda".Silicone based life-forms frown on this reporters shenanigans.[img829.imageshack.us image 640x480]
Jubeebee: "It's not unexpected that this sand pile would not be rich in organics. It's been exposed to the harsh Martian environment," added planetary scientist Paul Mahaffy
Biness: wouldn't you know it, they put ONE SUV on mars, and already theres a carbon problem./manbearpig
ObscureNameHere: Did they find out where Han's vest disappeared to, then re-appeared from, just before he was frozen?/go watch TESB closely....
PJ-: occamswrist: Now nasa can carbon date mars.I winder what age it will be?About 6000 years old give or take.
Perducci: ObscureNameHere: Did they find out where Han's vest disappeared to, then re-appeared from, just before he was frozen?/go watch TESB closely....He started taking it off when Leia was coming on to him. Then she brought up the whole "love" thing and ruined the mood, so he got dressed. Duh.
mutterfark: Just wait until the Martians living in their home soil realise that the rovers were built by ugly bags of mostly water.
Proteios1: Carbon. Simply a mind numbing discovery. And at a cost of only $20 billion, such a better investment than the Obama stimulus funds.
washington-babylon: Skyd1v:See the difference? Are we clear now? What life forms are we talking about, exactly?/pet peeve
brantgoose: Well, actually they found more than organic carbon. Some of the other elements which are necessary to Earth life, such as sulfur, were also found. The real interesting data should come from the mountain where rocks of different ages are exposed. We won't see that data for some time.If you were an alien looking for life on Earth you would note the presence of liquid water and be hopeful. You would note the large amount of free Nitrogen and Oxygen, both of which are sufficiently reactive to be doomed to be locked up in soil and rocks unless replenished constantly and you would be optimistic. Living organisms keep our atmosphere composition in the highly improbable state of being composed of about 20% Oxygen and over 70% Nitrogen. If we spotted a similar atmosphere we would be confident that it is a world like our own.Traces of CO2 would be intriguing to alien scientists. That is a fairly stable gas but it would seem odd that there is so little of it, but just the right amount to keep water liquid. Mars and Venus have atmospheres are are 98% or more CO2, one very thick and hot, one very thin and cool. Earth has a fine regulatory system that keeps things improbable and lively. It is life itself.Methane would neither confirm life nor disprove it, but methane can be a sign of life. And of course, the man-made greenhouse gases would be a dead giveaway that the planet is inhabited by morans who haven't learn to work within the system rather than against it.Mars has methane although it is not known whether the source is biological or geological. It is leaking out of the ground in some interesting places where life would be likely on, say, Antarctica.The surface of Mars is rich in perchlorates. This is not a good sign, but it is not impossible that bacteria can use perchlorates to survive under harsh conditions or produce them as waste.Life on Mars, if it was ever there and if it survives, is most likely underground, in the vicinity of volcanic vents and possibly ...
