Russia's Mars Mission Raising Concerns 245

eldavojohn writes "Space.com has a blog on Russia's Phobos-Grunt project designed to explore the planet further. He voices concerns about part of this exploration that is dubbed LIFE (Living Interplanetary Flight Experiment) and backed by The Planetary Society that involves sending several samples of Earth's hardiest microbes to see if they can survive the round trip voyage. Space.com's correspondent Leonard David did some legwork to ensure that The Outer Space Treaty of 1967 was being upheld as it prevents cross-contamination between planets and receives some interesting responses from experts on this mission. The Phobos-Grunt mission will also deploy a Chinese sub-satellite 'Firefly-1,' which will attempt to figure out how water on Mars disappeared. Unfortunately, The United States is not taking part in Phobos-Grunt."

    I don't know why we're so concerned about cross-contamination. The only potential downside to it that I can see is if it obscures evidence that life existed on other planets.

    I just find it hard to care about balls of rock and their 'pristine environment'.

        If 1950s scifi movies have taught me anything, it is that "there are some things mankind was not meant to know"

      • For absolutely nothing? What if we sent microbes to another planet and they were able to survive, then earth was destroyed in a cosmic event. That would mean that humans achieved moving life from earth to another planet. Yea, maybe we would be toast, but evolution would have still succeeded.

          Is there a logical approach to this or do I panic?(????? or profit?)

      • Yeah, why not just do a slingshot around the sun instead. We know most microbes on Earth wouldn't survive Mercury or Venus (not that we should deliberately try), so if we're just attempting to find out if they can survive the trip outside the magnetosphere for a long period of time, wouldn't the slingshot work bet? Just loop it around the sun and have it crash back on Earth.

        Something that has always bothered me though, is how likely is it that anything brought from earth would survive better than martian organisms that might exist?

      Well, the article cites fear of Forward-Contamination [wikipedia.org] which is

      the contamination of other worlds with Earth microbes. The risk of forward-contamination is twofold: that human beings may accidentally seed a previously sterile world, thus creating "extraterrestrials" that are really of terrestrial origin (and which might even make it impossible to determine whether the life later found is terrestric or local); or that an actual alien biosphere could be devastated by Earth's bacteria.

      So if these escape on Mars and we land later and find microbes how do we know that 1) they aren't really terrestrial or evolved descendants of our microbes and 2) they didn't inadvertently disrupt or destroy original organisms to the planet.

      I think it's more so a caution but scientists and people interested in the idea of life forming independently on other planets care very much so.

          I'm not sure why you brought up smallpox blankets ... I thought those were things designed to destroy the populations of already known indigenous peoples? I think a better analogy would be the rats that were on board the ship from Europe that made it to the New World or maybe even the pigs that escaped and made short work of the squash/tuber/corn plant systems the Native Americans depended so heavily upon? Look around you, there are many species in North America that were 'accidentally' brought here. Look at the Kudzu vine that was in resource contention with plants that didn't stand a chance against it? Smallpox blankets were basically germ warfare ... why would we bring germ warfare to another planet?

          Well, I have more faith in our current technologies and I am saddened that you don't think we can learn from our errors. You seem to be resigned to the fact that we will destroy whatever we visit but I disagree. We have the ability to manufacture germ free CPUs here on earth and I think we should do our best to keep our external systems and machines also germ free. I think we have even been fairly successful in that.

          Lastly, this outer space treaty was signed by many countries and for good reason: all the scientist thought it an absolute necessity.

              The 'real estate' value of Mars is always so totally overstated. NOBODY WILL EVER LIVE THERE. You want to know why?

              1) Because it will make much more sense to live in free space (IE on an asteroid or space colony) where you avoid the huge energy cost of going up and down a gravity well.

              2) Mars provides virtually nothing in the way of resources which are not available in places easier to get to.

              3) The environment of Mars is actually MUCH harsher than the environment in space, and probably much harsher than the environment of the Moon. So why exactly would we so desire to live there?

              4) If environments as harsh as Mars are desirable real estate for people to live on, then why aren't Antarctica and Green Land, and the Sahara Desert all chock full of people already? They are CERTAINLY much less harsh and much cheaper places to live. Good luck selling those Martian building lots...

              5) Even speculating about Terraforming is pretty much beyond science. The time and energy inputs required are probably 1000's and maybe millions or billions of times anything we can deploy today. The time frame could easily range into the millions of years no matter how capable you are. There is certainly no sense at all in planning a space program based on a payoff that somehow relies on a technology that is no more than an idle dream which might exist in 200 or 1000 years, if ever.

              This does all tie in to some extent to the OP, Mars' value is not ever going to be economic. Its value is purely scientific and there is no reasonable anticipation that it will ever be otherwise. Spoiling the pristine conditions on Mars would seriously degrade the value of exo-biology work done there in the future. So it IS a bad idea, and it would be a costly mistake.

              Now, the question of the actual safety of Phobos-Grunt is a whole other thing. We'll just have to leave that to experts. At least they value the principle of avoiding contamination. Maybe they're a little biased, but the risk doesn't seem super excessive to me. OTOH it also sounds like the experiment itself is mostly a PR stunt, so on that basis I'd give it the thumbs down. Not worth making a huge stink about though.

                Wouldn't Mars also be more desirable because it has mostly cleared the neighborhood of other heavenly objects such that the risk of one's home being smashed into by another particularly large rock is massively diminshed?

                Wouldn't it be fairly practical to bore down into Mars to construct a habitat with significantly less materials (like basically a cap at the top of the bore hole) such that materials from Earth aren't depleted nearly as much for space?

                Wouldn't it be fairly easy to distill elements from an atmosphere to come up with that which we need to survive as compared to attempting to find them in the vacuum of space?

                There are many good reasons for looking at Mars too, beyond the adventuring spirit.

                  What evidence is there to support that hypothesis? Granted, it is not far fetched, but we don't actually KNOW what
                  level of gravity has what effects. My guess would be that some effects might be mitigated, maybe even completely, others
                  might not be significantly reduced at all.

                  Plus, wouldn't even a thin atmosphere be better for protection and help reduce the need for vacuum-proof structures than near-vacuum conditions?

                  No, because the atmosphere of Mars is already close enough to a vacuum that from a physiological standpoint the
                  difference is irrelevant. The atmospheric pressure on the surface of Mars is 6 millibars, 1/150th of the pressure at
                  the surface of the Earth. From a standpoint of engineering a structure or breathing, it is no better than a vacuum. Yet
                  from the standpoint of carrying dust into everything and possibly facilitating corrosion and other equipment damage it
                  could prove to be quite a serious problem. So, I would, as an engineer, MUCH rather deal with the problems of the Lunar
                  environment than the Martian environment, since I will avoid all of those problems.

                  Wouldn't Mars also be more desirable because it has mostly cleared the neighborhood of other heavenly objects such that the risk of one's home being smashed into by another particularly large rock is massively diminshed?

                  Exactly how often do you think main belt asteroids collide with each other? On average not often at all. In fact such
                  collisions probably only happen once in many millions of years, possibly billions of years. Those bodies which were in orbits which were likely to collide with things mostly did so billions of years ago and were either sent into orbits where they no longer hit other stuff or were pounded to bits long ago. The chances of an asteroid hitting Mars are actually probably at least as high as those of one asteroid hitting another. Besides, if you have the technology to live on an asteroid, you can probably shift its orbit by a few 100 meters if you ever need to...

                  Wouldn't the fact of working in an environment with an up, a down, and other gravity-based rules like that which we have on Earth be easier for workers who have to do things like maintenance, construction, and the like be better than attempting to work in microgravity where accidently losing a tool means that it's probably gone forever instead of being able to just bend down and pick it up off the ground?

                  Oh, it would probably be easier for you or me right now today, no doubt. However zero g assembly IN GENERAL should be
                  quite easy. No need for massive cranes, scaffolds, support structures, etc. I highly suspect that once we are even 1/8th
                  as knowledgeable about zero g construction as we are about 1 g construction today we will have a much easier time with it.

                  Wouldn't it be fairly practical to bore down into Mars to construct a habitat with significantly less materials (like basically a cap at the top of the bore hole) such that materials from Earth aren't depleted nearly as much for space?

                  And why wouldn't this solution work equally well when dealing with an asteroid? In fact it seems to me it would work much better and be much easier. You don't have to DIG anything, just dump a whole lot of material around your habitat if thats what you need to do. No need to worry about tunneling or weight, etc. It

            The whole "keep Mars sterile" will go out of the window as soon as we put humans on the surface. It's impossible to 100% decontaminate the space suits before every single EVA. So we better figure out first if there's any indigenous life form close enough to our own make-up (if we find living silicon on Mars we probably didn't transfer it, but anything DNA based would be highly suspicious). I've worked on Mars sample return projects, and the requirements are pretty damn strict. But guaranteeing that not a single mold spore survives anywhere is pretty much impossible.

      Obscuring evidence that life existed on other planets is a huge downside. Once this has been done we can never go back and know whether or not life started only on Earth, or independently on the other planet. Since we only have a very limited number of potential abodes for life in the Solar System, and no realistic hope of ever leaving the Solar System, failing to ensure that there is no cross-contamination could ensure that we will never be able to answer some of the fundamental questions about life.

      Article IX

      In the exploration and use of outer space, including the Moon and other celestial bodies, States Parties to the Treaty shall be guided by the principle of co-operation and mutual assistance and shall conduct all their activities in outer space, including the Moon and other celestial bodies, with due regard to the corresponding interests of all other States Parties to the Treaty. States Parties to the Treaty shall pursue studies of outer space, including the Moon and other celestial bodies, and conduct exploration of them so as to avoid their harmful contamination and also adverse changes in the environment of the Earth resulting from the introduction of extraterrestrial matter and, where necessary, shall adopt appropriate measures for this purpose.

      The debate is already in Kim Stanley Robinson's "Red Mars" novel : should we protect other planets from earth's lifeforms ? While it would be nice to find definite proofs in favor or against panspermia, I would tend to be in favor of as much contamination as possible, as early as possible. Terraformation will eventually be scheduled. The sooner we start, the better.

    And the soil of Australia is red, just like Mars.

    This should work.

    I find it funny that we are concerned with damaging an extraterrestrial biosphere but are completely ok with trashing our own. I bet those up in arms about some _potential_ mars bacteria being wiped out, give a shrug and a yawn when told of the countless Earth species on the brink of extinction. I'm not saying they aren't worth protecting, but rather, we need to get our priorities straight here on the ground too.

      A recent National Geographic article listed several species on the brink. It's horrifying IMHO. http://ngm.nationalgeographic.com/2009/01/endangered-species/klinkenborg-text [nationalgeographic.com]

      There will ALWAYS be more that can be done Here before we do something There. But we still go There to expand horizons, provide vision, inspire minds and any number of other things that enhance our knowledge of the universe.

      Solely looking inward is the key ingredient to stagnation of civilization.

      The US and Russia went to space while paved roads were still measured in the thousands of miles.

      We go forward to find the 'now' of tomorrow.

      Heck, there are still uncontacted people in South America. S

        Agreed. I'm all in favour of space exploration. I just don't want people to be all high-and mighty about the need to protect alien microbes when we aren't even protecting our own planet. Humanity really needs to learn to be consistent.

      Two things to remember. First, trashing a biosphere only kills some species in that biosphere. As I see it, we could duplicate the Permian extinction, the worst in geological history (of the species then that left fossils, 95% of all marine species and 75% of all land species were lost), and yet still have a biosphere when it's over. With Mars, we have a very small chance of wiping out completely a biosphere we haven't seen yet.
  • The Phobos-Grunt mission will also deploy a Chinese sub-satellite 'Firefly-1,'

    Dahng rahn it's Chinese, the question is who's behind it? The Alliance? Blue Sun?

  • Life evolved on Mars first, because it reached geological stability sooner. Then it infected Earth via Martian meteorites. Dozens of meteorites from Mars have been found and that is probably only a tiny of percentage of those which have reached Earth.
