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?

      The Bible makes no mention of life on other planets. Instead it is focused on life here on earth and what Gods will is, and what his Kindom is, and who his Seed is.

      As for Religion being opposed to science in many ways, that has been very true. Even Gallileo was imprisoned by the catholic church because he believed that the Earth was not the center of the universe.

      You must realize though that these conflicts were between *religion* and science, not the *Bible* and science.

      The Bible, while not a scientific document (and it does not intend to be one) does hold some VERY accurate, simple scientific truths. While his contemporaries believed the world to be flat (along with science at the time), the prophet Isaiah spoke of "the circle of the earth". Another scripture speaks of the Earth hanging by nothing, which is accurate.

      Does the Bible have any real thoughts on whether or not there COULD be life anywhere else other than Earth? Well, it does speak of spirit creatures that exist in another realm, with God himself being one of these creatures.

      I hope this helps answer your question.

      As to my own upbringing, I was raised as a Christian, and in catechism class we were taught the question and answer:

      Q. What is the chief teaching of the Catholic Church about Jesus Christ?

      A. The chief teaching of the Catholic Church about Jesus Christ is that He is God made man. (A Catechism of Christian Doctrine: Revised Edition of the Baltimore Catechism, No. 2. Paterson, New Jersey: St. Anthony Guild Press, 1941, 15)

      But when I later went to a Catholic university, I could not help reflecting that man was limitary and finite, while God was not, and I asked myself why I believed that Jesus was God.

      If one could point in answer to the scriptures, I found that modern textual studies of the New Testament had raised large question marks as to that book's authenticity. In a course in theology, I read a work by Joachim Jeremias, one of the foremost exegetes of the New Testament in this century, who after a lifetime of study of the original, finally agreed with the German theologian Rudolph Bultmann that "without a doubt it is true to say that the dream of ever writing a biography of Jesus is over" (The Problem of the Historical Jesus, Philadelphia: Fortress Press, 1972, 12), meaning that even the chronology of the life of Jesus could not be established from the New Testament. So how then, I wondered, with the question of whether or not he was God?

      Indeed, although ordinary Christians seem quite unaware of the revolution that has taken place in New Testament scholarship by Christians over the past thirty years, if we look at the literature, we find such paragraphs as the following, from a textbook by James D.G. Dunn for university students in their third year of New Testament studies. The italics are his: Similarly the thought of Jesus' deity seems to be a relatively late arrival on the first-century stage. Paul does not yet understand the risen Christ as the object of worship: he is the theme of worship, the one for whom praise is given, the one whose risen presence in and through the Spirit constitutes the worshipping community, the one through whom the prayer prays to God (Romans 1.8; 7.25; II Corinthians 1.20; Colossians 3.17) but not the object of worship or prayer. So too his reticence about calling Jesus "God". Even the title "Lord" becomes a way of distinguishing Jesus from God rather than identifying him with # God (Romans 15.6; I Corinthians 8.6; 15.24-28; II Corinthians 1.3; 11.31; Ephesians 1.3, 17; Philippians 2.11; Colossians 1.3). Paul was and remained a monotheist. That reticence in calling Jesus "God" is only really overcome towards the end of the first century with the Pastorals (Titus 2.13) and again with Fourth Gospel (John 1.1, 18; 20.28). (Unity and Diversity in the New Testament: An Inquiry into the Character of Earliest Christianity. London and Philadelphia: SCM Press and Trinity Press International, 1990, 226).

      If the "thought of Jesus" deity"-which I had been taught was the chief teaching of Christianity about Jesus-was "a relatively late arrival on the first-century stage," meaning not taught by Jesus himself, then we might legitimately wonder where it came from. The answer seems to lie in the "Imperial cult" proclaimed throughout the Roman Empire shortly before the era of Jesus, a cult which enjoined the worship of Rome and the emperor. In the words of Hugh Schonfield, a translator of the New Testament, The cult had developed in the reign of Augustus [Ceasar], who for reasons of State policy accepted deification, and authorised the building of temples in which he was worshipped. He was formally decreed Son of God (Divi Filius) by the Senate. . . .

      Gaius Caligula (A.D. 37-41) [also] became obsessed with the notion of his deity, and his sycophantic officials played up to him. . . .

      A later emperor, Domitian (A.D. 81-96), insisted that his governors commence their letters to him, "Our Lord and our God commands." It became the rule, says [the Roman historian] Suetonius, "that no one should sty

    One thing I haven't seen discussed but would like to, is to what stage could life have evolved in the period that it was particularly ripe for life? In that time frame, could there have been significant multicellular life? Significant enough to leave interesting fossils? It has been a lifelong dream of mine to go fossil hunting in an old river or lakebed on Mars. I'm young, so I might still realize it (even though highly, highly unlikely), unless the period of wetness on mars didn't last long enough to have any hope for such things. I'd settle for piloting a probe equipped with a little pick and brush. Fingers crossed.

  5. 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?!?

    Quoting the author of "Creater and the Cosmos" (book). Sorry I don't have the name, I memorized this but forgot the guy's name. The book is not in front of me.
    I predict that someday life will be found on Mars. This has nothing to do with the origins of life. It has everything to do with Mars' proximity to Earth.

    He went on to describe how bacteria are routinely found in the upper reaches of the atmosphere, and how meteorite impacts are almost certain to propel them into space. Furthermore, he described how many species of bacteria form spores, and that these spores were known to tolerate high temperatures, low temperatures, radiation (!), and exposure to a vacuum for an extended period of time.

    In essence, bacteria can make the trip to Mars. The only question is whether or not Earth bacteria can survive there.

    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.

  9. 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. :)
