The Green Hills Of Mars

The Green Hills of Mars

Since the earliest days of astronomy and indeed into the deep recesses of history there has remained within the human psyche an abiding desire to know what life might inhabit the worlds that share our solar system. Looking into the night sky with the naked eye upon Venus and Mars our ancestors wondered how and why these stars behaved differently than those of the background. These stars like the others of their kind in time came to be known as planets.  In our imaginations they took upon the names and characteristics of whatever local god seemed appropriate. There in the sky the planets of love and war dominated their arena in the same ways that these aspects of life dominated us. Later as notions of what it really meant to be a planet grew more mature so too did the imagery used to depict them had become.  
However in the absence of true knowledge so deep was this desire to know these unknowable places that men began in their imaginations to create visions of ornate fantasy. On these worlds fantastical realms there in existed, each populated by dragons, fairy kingdoms, and hot steamy jungles. And in the case of Mars, there even existed a worldwide system of canals. All of these were readily created to fill the void left by these knowledge gaps.  

 We now know much to our disappointment that Venus and Mars are for the time being uninhabitable. One has a shrouded atmosphere many times denser than our own with temperatures hundreds of degrees hotter than our own. And the other is a barren lifeless dessert with little if any atmosphere to speak of.  Despite how much we have learned the most basic questions have remained unanswered. Is it possible that even in these most desolate environments, can and does life exist beyond the Earth?
Let’s look at the evidence so far. We do not because of the extreme environments on Venus yet possess the technology that would make such a voyage possible. Perhaps in a future time we will make that leap. But for purely practical reasons we must focus on Mars.

I’m old enough to remember references from science texts to the green seasons on mars. Maps indicting the dry and wet cycles were considered by some to be of sound theory. It was  astronomers like Schiaparelli and  Percival Lowell who in the late nineteenth and early twentieth century s  who popularized such notions. Though extrapolations on grand canals and advanced cultures had maye missed the mark had they perhaps in the world before color photography visualized a rare and anomalous greening event?

By the nineteen seventies these ideas had been firmly dismissed by science.  Imagery of Mars showing it to be the arid and cold wasteland that we know today had existed for some time.  By the time the twin Viking landers had touched down in 1976 the consensus was that Mars was a dead world. The mission would be one of confirmation rather than discovery. To their credit however a number of biological experiments were conducted.

 When the results of these experiments were released to the general pubic Mars was officially declared dead. There were however within the details contradictory results that some say  showed just the opposite. In particular the Viking biology package GEX/LR/PR designed to capture the telltale signs of chemical metabolism in soil found some interesting results. However in the absence of earth-like organic compounds these results were considered to be no more than an aberration.

Viking chemistry of life soil experiments

Since that time four rover missions have successfully touched down on the red planet. What they have discovered there along with what we now know about extremophiles on earth has been revolutionary in the field of planetary science. With the use of rovers and satellites have found conclusive evidence of past and possible current water that could be trapped below the  frozen surface. We are forced now to reevaluate and replicate those early experiments.


 1996 an announcement was released which made headlines around the world. What they discovered within  a 4-billion-year-old Martian meteorite found in Antarctica was shocking. Under microscopic examination they discovered  there what appeared to be fossilized bacteria. The excitement that followed this amazing news was however short lived as this evidence was deemed once again to be inconclusive.
 The other day I read of another discovery this time from a meteorite that struck Egypt in 1911. The article describes a find similar to those of the Allen hills discovery of 1996. In this case however structures more similar to what would be described as cellular or similar to earth biology was found. Now however because such Ideas are chastised within the scientific community they are all but ignored. I not being a scientist do not have a professional reputaion to throw away by advocating such notions.


additional reading

I could make the case that there is now sufficient evidence to place a manned mission to Mars squarely at the top of our scientific priority list. We as humans have a deep seated desire to make the discoveries that answer these questions. However in the last fifty years the arbiters of science have stalled this human urge by continually denying the possibilities on the grounds of insufficient evidence.  Currently there are grand plans on the boards at NASA yet as always they remain twenty years or more away. The unfortunate truth is there is no political will to make the commitment to use the necessary resources. Are we doomed to be a one planet species?

The four modes 

Since before dawn of human history man, through his senses has created  imagery of himself and the spirits that populated his world.  At a lost point in history wild troupes of humans began to wander barefoot out of the wilderness for the safety of  a community.After having partially abandoning the natural  world  they then had need then to bring a sense of order or to reconcile themselves to his ever new world. There at the genesis of culture as the challenges of an changing landscape grew in complexity abstract ideas
had need to develop.

Its a difficult thing to keep one's outlook on the world fresh as it was in youth. This is why we are drawn to imagery, words, sound, and motion. The four modes to which biology translates the outside world into our thoughts from our senses. In a previous post I noted how in art  there is little hope in capturing anything close to a simulacrum of an experience. Despite this being any artists abiding dream I still believe it to be true. It however may never have been the point of art in the first place. Could it be rather the exercise itself or the discovery of a new manner of seeing to which we are moved? Serendipity or a happy accident could this be from where original thought springs forth? There an all seeing subconscious that never sleeps and a biological system sifting through reams of input are combined to create a new "vision".

Our ancestors looked to these four modes as a means of bringing flesh to ideas that had no natural equivalence. weather it be the beating of a drum to capture a fleeting rhythm or a line to define the  edge of a real or an imaginary form. Even it today's world where serious discourse is dominated by scientific ideas there remains a desire to pull from the realm of perception something more. So perhaps the artist as modern day shaman can lead us out of the wilderness to a new landscape.

So in this spirit I have conducted a little experiment. Please forgive me however despite my intentions I suspect the following to be a bit pretentious.;pageID=3117953744996442538;onPublishedMenu=pages;onClosedMenu=pages;postNum=0;src=pagename

The realms of the very small

What we consider to be subjective reality is often determined by the scale in which the subject is observed. Take for example the relative strength of a puny ant compared to the most powerful human weight lifter, there is just no comparison the ant wins every time. While driving out west large mountains can appear small at a distance. Growing larger over many hours their true mass is discovered.

In my last post I discussed the leaps in evolution that were required to reach the point at which we now find ourselves.  I described how simple two dimensional single celled organisms had for the benefit of their species joined together to make a play at a three dimensional world and in doing so had become a whole greater than its parts.

 Part and parcel to this transformation would be the sense of individuality that is afforded by this type of existence. This notion of individuality however when looked at from the perspective of the very small becomes less clear. On these scales there is another world in which we inhabit, to which none of us are ever truly conscious to. There we are forced to discover that we did not wholly abandon the world of the microscopic. On these scales the tissues and organs of our bodies begin to resemble tiny machines and factories. Within our bodies thousands of these mechanisms work continuously to keep us alive by producing energy, repairing and replacing cells, and defending itself from foreign invaders.

                              Meet my organism

That’s where my organism comes in. I would introduce you to it however it has no name. But then again he doesn't need one. Its true shape is hidden beneath a mass of skin supported in an erect position by a bony frame of skeleton. It interacts with the world in much the same way as a mollusk tasting and feeling its way about.  I envision it to be akin to a six foot worm. To this worm as a child my consciousness was grafted. Each year as I grew older toward adult hood less and less off its original nature was evident to my fledgling mind. Now in a mature state it rules the world of my subconscious warning me of danger and thirst, and oddly precognizant of things in a way I can’t understand. This organism exists in the world of the microorganism where it fights everyday for survival against hosts of foreign aggressors. These aggressors are made up of the greater biome that surrounds us.  It is also from this world where arises our primitive drives and emotion that many of us spend a lifetime attempting to master. Though we may have conquered the façade of the macro world there seems to be a constant struggle within the micro world which we can never win. The truth however may be more surprising for in fact we for a long time have reached a kind of Symbiotic equilibrium with our tiny friends.


This week the below referenced articles caught my attention and started me thinking along these lines. In the article it referenced in brief a study that described how closely intertwined we are biologically in relation to the world around us.  

The article goes on to describe how our personal biomes are made up of organisms that are highly specific to our own bodies and households and distinct from others. It is well known that these organisms live upon and within our bodies in numbers that far exceed those of our own native human cells. So vast in number are these cells they behave as a benign cloud of life colonizing every environmental niche our bodies come in contact with. These organisms are highly mobile they go where we go. So pervasive are they that within hours of checking into a hotel our own individual biomes will replace those of the previous occupants. In the future because of the highly specific nature that each of our biomes possess it may one day be possible to develop new identification tools akin to fingerprinting. One day these may even prove more reliable than the current standard DNA sequencing.

                                         The secret life of Insects

Scale it up a bit to the level where limbs and appendages take shape. There on these scales just below our ability to distinguish them, hosts of tiny creatures inhabit our skin hair and nails tagging along for a ride. These creatures are just small enough to go unseen yet under a microscope they are familiar enough to be recognized as animals. These tiny creatures since the dawn of time have been evolving along side us on a parallel course. Evolution has ensured that we are exceedingly well suited at acting the part of a host for these happy critters. Whether we like it or not, like the hosts of animals that survive on the fringes of our society we have come to a state of equilibrium with these benign travelers. Spiders, rats, and roaches however that's another story entirely.
