NASA May Have Killed The Martians

Sneakernets writes "CNN reports that NASA may have found life on Mars via the Viking space probes in 1976-77, but failed to recognize it and killed it by accident. Dirk Schulze-Makuch, a geology professor at Washington State University, says that Mars microbes that the space probes had found were possibly drowned and baked by accident. Other experts said the new concept is plausible, but more work is needed before they are convinced. From the article: 'A new NASA Mars mission called Phoenix is set for launch this summer, and one of the scientists involved said he is eager to test the new theory about life on Mars. However, scientists must come up with a way to do that using the mission's existing scientific instruments, said NASA astrobiologist and Phoenix co-investigator Chris McKay.'"

      There are two things here.

      First, there is an 'energy' definition of life. That is to say, alien life may not be carbon-based, may not use water, may not be composed of cells, and may not have DNA inside of it. However, one of the defining characteristics of life is that it uses energy. It metabolizes, grows, and reproduces. It eats something, somehow. It makes a waste product.

      So, if we look at a planet's chemical composition, we can make a good guess as to whether there is life there by looking at its chemistry. If there are living things there, they will be making reactive chemicals. From outer space, we could tell that the Earth has a lot of metabolic activity in it, because the sky is mostly highly reactive oxygen that is a result of plant respiration. Mars, on the other hand, is mostly chemically inert. There is very little metabolism going on there, if there is any at all. Either life there has already eaten up the planet, or else there wasn't enough resource to really get started, or there was never life at all.

      Secondly, let's talk about a scenario where life can really only happen with water and organic ( meaning carbon-containing ) compounds. What conditions are necessary for life? What conditions does life thrive in? Take the Earth as an example. Where do we find the greatest mass and biodiversity? In the oceans. Ocean water is practically alive itself, there is so much life in it. On land, the places with the greatest biomass and biodiversity are the rainforests, where they have near 100% humidity. So water as a medium seem to really grow and reproduce. What temperature range do we find the most life in? About 70-90 degrees F -- I'm talking about the *most* life. So the metabolism of life forms seems to function optimally at 70-90 F.

      The point I'm trying to make is that yes, we do find life in weird places on Earth -- inside solid rock, in 200 degree sulfuric vents on the ocean floor, inside nuclear reactor cores. However, there isn't very much of it in terms of biomass, and there's not much diversity of forms. My guess is that those 'extremophiles' are descendants of creatures who lived in more hospital environments and became adapted to increasingly extreme environments. I don't think that life originated in rocks or in ocean vents. I think life originated in an environment that is most like where we find the greatest biomass and biodiversity -- water in sunlight at about 60-120 F.

      If we're not talking about the above scenarios, we are getting away from materialism, and thus science. This might include "Imagine beings of pure energy" (hey, atoms are 'pure energy') or "What if the sun is conscious?" ( well, we can't measure consciousness *yet* so we can't tell scientifically ) These are fun to think about, but scientifically they are kind of a non-starter.

      I understand what you're saying about thinking outside the box, expecting the unexpected, and not limiting our minds or our past experiences. But science puts some serious restraints on what we can imagine or postulate *scientifically*.

None of these involve the sort of environment where life thrives today.

      BTW, one thing most hypothetical scenarios of life on Earth share is the supposition that life -- and specifically photosynthetic organisms -- came long before free Oxygen did.

Organisms don't evolve to use energy more efficiently unless they encounter selective pressure ( and of course, one selective pressure is competing against more efficient organisms ). They are happy being sloppy, inefficient eaters, so long as they are able to reproduce. But, cells that consume food so efficiently that there isn't any more food for them in their immediate environment simply die. So there is a point which there is selective pressure *against* more efficient energy consumption. So evolution doesn't necessarily produce maximum efficiency. It produces minimum *necessary* efficiency. It's survival of the good enough, not the greatest.

      NASA pushes life on Mars as a possibility because it's a justification for their continued existence and their proposed (pointless) manned trips there.

      For the longest time NASA was pushing the ISS as a justification for NASA's existence. So be it. We do need a space program as such, and we need to fund it. The public needs to support it for the government to fund it, so pushing one or two generally interesting things into the media is not a bad idea. Going to Mars as such is also not a terrible idea, there are a lot of problems to overcome in order to make such a trip, and for further space explorations, overcoming those problems is crucial. For that reason I consider a trip to Mars a good idea.

      There is one main problem with sending people to Mars, and that is cost. This can easily be reduced to a fraction of standard calculations by changing the trip from a return trip to a one-way trip. We could send a phenomenal amount of stuff to Mars for the price of a 5 person return ticket, including five people (or a few more), so that is the most sensible thing to do. Finding five qualified volunteers would be easy.

      Interestingly, giving them a one-way ticket would probably significantly increase the general populations support for a general space program, since they would stay there for a long time. The general population would feel a duty to assist them in their exploration, not let them die. In that way, our space program would probably be securely funded for the foreseeable future.

    You can be sure the probes brought some microorganisms to Mars...

    And given microorganisms are quite more resilient, than, say, mammals, who knows. Those probes might begin the life on Mars, if there wasn't any.

    If you follow how nature works, there's only one thing to know: life will push and proliferate in incredible ways, if given the chance. The probes could've been enough of a chance.

    There is no principled definition of "life," just like there is no principled definition of "planet." These are terms that we inherite from traditions that cut up the world into categories that, knowing what we do today, we can most certainly tell that the world does not respect.

    To the founders of astronomy and biology, it seemed that there was a clear and uncontrovertible difference of kind between, for the former, stars (which moved in circles, to put it roughly) and planets (which had a more irregular trajectory in the sky), and for the latter, living creatures and inanimate objects. When it comes to the latter, also, the idea that facts about living creatures could be wholly explained in terms of facts about inanimate objects was a hard one to swallow.

    We, today, on the other hand, know of all sorts of celestial objects of all sorts of compositions and moving in all sorts of trajectories; we know about viruses; we know about molecular biology; we have the theory of evolution; we have speculative theories of abiogenesis; and so on. These are things that show that the traditional concepts we have received are based on flawed assumptions.
