    An interesting article on a new mathematical analysis of data from the Viking landers that seem to suggest that biological not geological activity was detected in 1976 by NASA.

    Still a long ways from resounding proof however, but worth a look I think.

    Gilbert Levin is a co-author of the paper. Levin designed the Labelled Release experiment on the Viking landers. This experiment gave a positive result for life. To a lesser degree the other two life detection experiments also gave positive results. All of these were discounted since the GCMS (Gas Chromograph-Mass Spectrometer) revealed no organic matter. Subsequently the consensus view was that chemical reactions in the soil accounted for the results. Levin has long maintained that GCMS lacked adequate sensitivity and the LR experiment had detected life. This paper is part of his ongoing efforts to make his case.

    This sounds like another conspiracy theory to me. There may have been life on Mars in the past, but there is none there now.

    And you know that becuase you've been there and checked for a few years with mining and drilling equipment?

    On balance I would be rather surprised if there is no life on Mars today. However, that constitutes a considered opinion rather than a well founded hypothesis. If there is life present then I would strongly suspect the Viking experiments did detect it - which would make a generation of researchers look quite dumb in retrospect. (Or currently if you lean to the validity of Viking results.)

    There is life on Earth in places harsher than some parts of Mars. Based on just this one testable fact, we can say there may be life on Mars presently.

    I have never thought the Viking landers found life on Mars. There were chemicals found that were said to "mimic" life. Whatever that means. Certain scientists want to find extraterrestrial so bad that they will exaggerate, probably even lie to get in the news.

    That seems the least probable of all possibilities. Evolution to adapt to new environments is incredibly powerful; if Martian life even works a little bit like it does on earth: If it started at all it more than likely found a way to survive.

    Perhaps it did by somehow finding a way to Earth. Since there have long been theories that life on earth may have been preempted from life coming to earth from some where else in space, is it not at least possible that Martian life ended up on Earth?

    Consider that complex hydrocarbon chains have been discovered in comet(?) debris.
    If indeed they fell to earth, then why not to mars?

    from the nasa site:

    long hydrocarbon chains formed on the surfaces of comets over time may be important for pre-biological chemistry in the solar system. And the rare molecule C2, found in comets, may have come from interstellar space (from beyond the solar system); Carbon stars are important for evolution (of matter), the abundance of carbon in all its forms may provide a clue about the stellar birth of the material itself.
    Ok? does that discount the viking findings?

    I wish life is found on the Mars or any other planet in our universe asap, because Earth is going to be short of space and resources to bear the growing human population. I am very enthusiastic about this.

    I'm enthusiastic about Curiosity. Reports mention some water washed stone gravel beds being detected. Curiosity must have now travelled to the opposite face of Mars, the one opposite to ours I mean. Not a Picture. No Roman coins. No stone walls. No flints. Probably run out of petrol. westwind.

    Sorry Mr. John. The Bait was not for you. It is just that I have a lot of frustration at the moment due to being restricted to breathing only occassionally as the need arises. But I'm on the road to recovery. I doubt many people have ever arrived at Recovery, but I guess its a nice place if you are fortunate enough to arrive there. No, MW has not been Threading or Posting on the plight of Curiosity, and any achievements that may be of interest. MW input is vital to me, too much goble-de-gook on the Internet. I'd rather read MW'S understanding as to what's going on. Is MW on another Planet or what? I'll give him time to put something together for The Members of The Science Forum. But I'll not be lieneint with Him this time.

    Now I have your attention John, could you poste a Verse on new Cosmos Galaxy Universe Thread.? westwind.

    Think you have our moon and Mars mixed up. There is no opposite face of Mars.

    For Lynx Fox. Well Curiosity better be getting along and detecting the opposite Face of Mars, because Curiosity is fast losing Face with me. The Best Science Story this Year and such frustration for me waiting impatiently for layman Science to be thrown up for discussion by Members. Not a Word. Mosewell have landed upside down. westwind.

    LOL. Well at least we're getting IPOD quality pictures now. I still think they picked the wrong location, but Curiosity will probably turn out some fascinating stuff over the next year or two and hopefully put the Viking data ambiguities to rest once and for all. It was nice to get on the ground confirmation of the water flows Global Surveyor showed us. A "no life," verdict would be a bummer but not really a surprise.

    When I heard NASAs "new plan" to return samples by the 2030(s) last week on the radio, I screamed in frustration. No ones going to get excited about that -- and darn few are going to write their congressmen to support NASA funding. Until NASA fixes its PR problem and takes the voters fickleness and emotional desire for a human factors into account instead of criticizing their masters for low attention spans, its budgets will remain on life support.

    I don't know why anyone is surprised at the timeline. From the start, the mission design was to take 1 year to get to the base of Mt Sharp.

    And all sarcasm aside, Lynx, your "IPOD quality" remark is uncalled for. There are multiple high resolution panoramas, close up images of the rocks they sampled that showed at one time there was deep flowing water for a significant period of time (years).

    I don't post much here because the image posting sucks, and there is so little interest, but my hard drive sure is filling up!
