Biological Activity on Mars

visination.com writes "Recent ground based observations of Mars have confirmed the presence of water and methane. The 300 year life time of methane on Mars is short, giving scientists reason to beleive that Mars may be biologically active." From the article: "Every one of these longitudes shows a very substantial enhancement in the equatorial zone...So this is a very intense source of methane on Mars in this region. It also requires a very rapid decay of methane...more rapid than photochemistry would allow..."

    Okay, firstly, I am not a follower of any major religion, and I have not read the bible, so that is the purpose of this question...

    After reading that article, and then reading another article advertised on the same page here I was starting to feel as if i would be surprised if we DIDN'T find evidence of life on mars. Anyway, I was just wondering what remifications such a finding would have on the bible followers. Is there any reference in the bible as to whether life on other planets exists. Almost every scientific discovery is met with religous opposition, so I was wondering if anyone had any opinions from the religous area. Does the bible say anything about life on other planets?

  2. Provocative Pictures from MOC by Derling+Whirvish · · Score: 4, Interesting

    There are some rather strange images from the Mars Orbiter Camera that don't appear to show geologic activity at first glance and do resemble bacteria beds or something organic. We need to go investigate!

      Even more such pictures are at this site dedicated to pointing them out. Wow. Just wow.

  3. Why isn't the data coming from more close up? by DumbSwede · · Score: 4, Interesting

    I understand the one-step-at-time approach NASA is pursuing with regard to the search for life on Mars, but it strikes me a little odd that the methane concentrations on Mars are being measured by telescopes based here on Earth. Why haven't current orbiters been equipped to sense this in a more direct fashion. I would think exact precise chemical composition of the air would be a high priority. In fact, how sensitive would the Viking data have been on showing possible methane concentrations in the atmosphere? My recommendation to NASA: more emphasis on chemical analysis in future missions. Yeah, I know the Rocket Scientists are probably already thinking this. Hopefully this new data will get the proper equipment funded for the next Mars shots. And yes I know everything is a trade off and we do chemical analysis as part of every mission to some degree. But damn, we have to use scopes here on Earth to get this data?!?

  4. ESA probe by jd · · Score: 4, Interesting

    The ESA "mothership" that deposited Beagle 2 all over the Martian landscape has a spectrometer and it has been observing methane releases for some time. The ESA has been unsure, though, whether it was due to life or geological activity. Trust NASA to go with the more exciting option, with no more data to go on.

    Before we destroy them, ought we not study them. Important questions beckon if this does pan out. Off the top of my head:

    1. Does this life chemically resemble life on Earth?

    2. If it does, does it use RNA/DNA or something very close to these molecules?

    3. If it does, then is Mars or Earth or possibly some other place in the solar system the point where the initial abiogenesis occured?

    4. If Martian life does not appear to be closely related or at all related, then what possible abiogenesis pathways occured to produce Martian organisms?

    There's a lot to be learned about both worlds from this, so I hope before someone decides to terraform they learn a considerable amount about any potential biotic activity on Mars.

  6. There is more than just Methane by iamghetto · · Score: 5, Interesting

    Dr. Vittorio Formisano is/was the principle investigator of the Planetary Fourier Spectrometer used by European Space Agencies Mars Express probe.

    From reading the spectrometer, he believed it was evident that methane, ammonia, and formaldehyde can all be found in the martain atmosphere. Where as methane will last a few hundred years in the atmosphere, formaldehyde will only -eight- hours.

    I'm not a scientist, but from what I've read, all 3 gases are strong indicators of life. While I know that the methane could be produced by volcanic activity on Mars (as mentioned elsewhere in the thread), Mars is a geologically dead planet. There is no sign of any such activity.

    The presence of all 3 gases on a geologically dead planet would seem to be consistent with planet having some microbial life. As Mars entered its Spring, the levels of all 3 gases were found to rise as well. Of course, more life, more gas in the atmosphere.

    It was also noted that the gas levels rose sharply over Mars' frozen oceans as spring approached. Perhaps some simples forms of life were frozen in the oceans? It could also be that the frozen oceans sit over some geological vents, trapping some methane.

    But again, as far as anyone knows Mars is still a geologically dead planet.

    Sorry if this doesn't make much sense... but gas indicating life in the martian atmosphere is OLD news, and there are far more compelling gases (like formaldehyde) that exist in the atmosphere. If it only lasts for 8 hours, something there is reproducing it.

    Apparently, the only way to know definitively what is producing it, is to go dig up the soil. So... good luck on that ever happening. Apparently we have to build a base on the moon first. :)

  7. Cows by luna69 · · Score: 4, Interesting

    A Mars researcher currently working with data from the Opportunity rover told me a couple weeks ago that he and some colleagues calculated what it would take to produce the levels of methane observed on Mars.

    Their results? Three cows. Seriously.

    I have no idea how accurate those calculations were, but he's a smart guy with more degrees than I have.
