Cosmic Rosetta Stones?

"Mt. Sharp" in Gale Crater - Mars
Curiosity Rover is at a location on the planet Mars that has recorded a billion years or so of Martian history.

If you think about it, the location has recorded early solar system history, and it promises to tell us a lot about what happened, not only to Mars, but to our whole solar system.

Like the Rosetta Stone did to help with ancient human languages years ago here on the Earth, this may help us interpret some of the various "languages" or messages in the geological record throughout the solar system.

The Mars Journal provides peer reviewed papers for those interested in detailed discussions of Martian geology.

Years ago the Opportunity Rover discovered what NASA folk nicknamed "blueberries", which were ball-bearing shaped objects made of hematite, an iron oxide.

It was originally thought that those spheres of hematite here on Earth, and by extrapolation those on Mars, were chemically produced, not organically produced.

However, and to the contrary, new research of similar hematite spheres here on Earth has found that those here on Earth were formed by microbes:
Spherical iron-oxide concretions - dubbed "blueberries" - were first found on the Red Planet in 2004 by an earlier NASA robotic probe - Opportunity Rover - providing some of the first evidence for liquid water on Mars.

Earth-based analogues for these "blueberries" are found in the Jurassic Navajo Sandstone near the Colorado River, Utah, where the concretions range in size from small marbles to cannonballs and consist of a hard shell of iron oxide surrounding a softer sandy interior.

Previous theories suggested these concretions were formed by simple chemical reactions without the help of life. However, new UWA research shows clear evidence that microbes were essential in their formation.

This raises the possibility that Martian "blueberries" may not only reveal that water was present on Mars - but life too.

(Phys Org). This may also hold true for the new type of "blueberries" found in Endeavour Crater very recently, found also by the Opportunity Rover:

NASA's long-lived rover Opportunity has returned an image of the Martian surface that is puzzling researchers.

Spherical objects concentrated at an outcrop called Kirkwood on the western rim of Endeavour Crater differ in several ways from iron-rich spherules nicknamed "blueberries" the rover found at its landing site in early 2004.

"This is one of the most extraordinary pictures from the whole mission," said Opportunity's principal investigator, Steve Squyres of Cornell University in Ithaca, N.Y. "Kirkwood is chock full of a dense accumulation of these small spherical objects. Of course, we immediately thought of the blueberries, but this is something different. We never have seen such a dense accumulation of spherules in a rock outcrop on Mars."

(Mystery Spheres on Mars, NASA). The spherical objects at Endeavour are not of the same composition as those found in 2004 shortly after Opportunity landed.

These discoveries lend some credence to the hypothesis of some NASA scientists that some microbes found in meteorites on Earth, whose descendants may be alive today, originally came from ancient Mars (A Structure RE: The Corruption of Memes, quoting Journal of Cosmology).

The exploration of space is never boring, especially when contemplating the full impact of the Tenets of Ecocosmology.

On The Origin of Propaganda

The old Trees of NYC
Would you, as I once did, think that "propaganda" began in the NAZI Germany of old?

Is propaganda only something that humans do?

For the purposes of this post, we will define propaganda as anything that deceives others.

That is, anything that advocates or nurtures a false sense of reality in others so as to lead a victim or victims into any behavioral pattern that is believed to be real, but in fact is actually unreal.

Additionally, we will expand that meaning to include activity in the environment, the ecosystem of the entire Earth.

This is not being done to denigrate the "natural" world around us, rather it is being done to show that many activities that take place deep within that realm we call nature are behaviors that are not "good," in the sense of Ecocosmology, so we need not define them as "good."

Most microbial life is helpful to other life, only about 1% being pathogenic or harmful to humans, who are composed mostly of microbial cells.

Our first example of propaganda usage is about Sacculina, a parasite:
When a female Sacculina is implanted in a male crab it will interfere with the crab's hormonal balance. This sterilizes it and changes the bodily layout of the crab to resemble that of a female crab ... The female Sacculina has even been known to cause the male crabs to perform mating gestures typical of female crabs ... The natural ability of regrowing a severed claw that is commonly used for defense purposes is lost after the infestation of Sacculina. Although all energy otherwise expended on reproduction is directed to the Sacculina, the crab develops a nurturing behavior typical of a female crab... The male Sacculina looks for a female Sacculina adult on the underside ... then implants himself ... and starts fertilizing ... The crab ... then cares for the eggs as if they were its own, having been rendered infertile by the parasite.
(Wikipedia). Can there be any stronger deceit or propaganda than to deceive a male into thinking it is a biologically functioning female, robbing that male of reality?

Let's take a quick look at two other examples, beginning first with the protozoa Toxoplasma gondii:
If you take a lab rat who is 5,000 generations into being a lab rat, since the ancestor actually ran around in the real world, and you put some cat urine in one corner of their cage, they're going to move to the other side. Completely innate, hard-wired reaction to the smell of cats, the cat pheromones. But take a Toxo-infected rodent, and they're no longer afraid of the smell of cats. In fact they become attracted to it. The most damn amazing thing you can ever see, Toxo knows how to make cat urine smell attractive to rats. And rats go and check it out and that rat is now much more likely to wind up in the cat's stomach.
(Hypothesis: Microbes Generate Toxins of Power). The acts of propaganda also take place in order to deceive plant species:
Phytopathogens can manipulate plant hormone signaling to access nutrients and counteract defense responses. Pseudomonas syringae produces coronatine, a toxin that mimics the plant hormone jasmonic acid isoleucine and promotes opening of stomata for bacterial entry, bacterial growth in the apoplast, systemic susceptibility, and disease symptoms. We examined the mechanisms underlying coronatine-mediated virulence and show that coronatine activates three homologous NAC transcription factor (TF) genes, ANAC019, ANAC055, and ANAC072, through direct activity of the TF, MYC2. Genetic characterization of NAC TF mutants demonstrates that these TFs mediate coronatine-induced stomatal reopening and bacterial propagation in both local and systemic tissues by inhibiting the accumulation of the key plant immune signal salicylic acid (SA). These NAC TFs exert this inhibitory effect by repressing ICS1 and activating BSMT1, genes involved in SA biosynthesis and metabolism, respectively. Thus, a signaling cascade by which coronatine confers its multiple virulence activities has been elucidated.
(Cell - Host & Microbe). This is akin to war practices in the days of castles, with draw bridges and moats, in the sense that sometimes enemies would dress up like knights of that castle, then rushing toward the castle would give a secret signal that deceived the guards into lowering the draw bridge, allowing the adversary into the castle to wreak havoc.

What has been illustrated is that propaganda does not exist only in the human realm, and therefore brings the definition of "natural" to the table.

That debate takes place in both politics and law sometimes, so that what is "natural" ends up being defined as "anything that happens in nature."

We can see that there is a better definition of "natural", and that definition is The Tenets of Ecocosmology.

In other words, "natural" is that which perpetuates life forms which are not part of the process that would take away or impair the ability to comply with The Tenets of Ecocosmology on any planet.

Not only does the definition of "natural" require a sense of perpetuating all good life, but it also requires the sense of perpetuating that good life so that all good life may validly continue out into the cosmos as its planet's host star goes into deadly demise.

Resource Based Economy

Tenet 3(a) of The Tenets of Ecocosmology relates to how the fittest civilization is the one that conforms to the norms of the ecosystem it dwells within.

Environmental awareness is an essential quality for civilizations fit enough to survive.

A TED talk discusses how economies and cities could work if that were to be accomplished with global implementation:
