Iapetus

New -- 1 May 2007

Nowhere is objectivity in modern science so clearly challenged as in the case of the wildly eccentric moon of Saturn, the one named after the Greek Titan, Iapetus. It is one thing to have the kind of variations in geologic characteristics as are exhibited by the Galilean satellites of Jupiter; it is quite another to have a sufficient number of totally unique features so as to require some extraordinary and highly creative explanations. In terms of anomalies Iapetus is loaded!

The Yin/Yang Moon

There is, for example, the solar system’s most dramatic variation in the coloration between the leading and trailing hemispheres of the satellite. This premier feature of Iapetus has been referred to as the Yin/Yang appearance, first captured in all of its glory in the first images taken by the Voyager spacecraft. [1]

 

What pray tell is this? It is not something you get due to light impinging on only one portion of the surface or shadow effects. This is something quite different. Yin/Yang satellites are simply not a common feature of moons in our solar system.

When Iapetus was discovered in the 17th century by Giovanni Domenico Cassini (1671 to be exact), he observed with his small refractor telescope the fact that the faint moon was apparently disappearing for a good portion of its 79-day orbit. The satellite would be visible during one elongation (i.e. when it was furtherest from its host planet, Saturn, as viewed from Earth), but then become progressively dimmer as it passed behind the planet. Eventually it would completely disappear as it approached its elongation on the other side of the planet (and was no longer shielded by the planet or its brilliance). As it continued on around and passed in front of Saturn, Iapetus would begin to reappear first as an extremely faint object, and then steadily increase until it again reached its original brightness in its original elongation. This process was repeated every 79 days.

Cassini assumed – correctly as it turns out -- that the extreme variations in the brightness of Iapetus had to be due to the fact that one hemisphere of the moon was vastly brighter than the other half – and that furthermore, the moon was synchronously rotating about Saturn with one hemisphere continuously facing Saturn – just as the Earth’s moon always has the same hemisphere facing the Earth. The only distinction was that Iapetus had a 79-day orbit about Saturn, while the Earth’s moon had a roughly 28-day rotation.

Importantly, if the leading hemisphere of Iapetus (which never changed) was very dark, and the trailing hemisphere comparatively much, much brighter, then simple geometry would dictate what was being observed. This geometry is shown below [1]:

 

It is probably worth noting that no other satellite in the solar system has anything similar to the black/white hemispherical faces of Iapetus. Many moons may have only one face to present to their host planet (e. g. Earth’s moon and Jupiter’s Europa), but nothing that presents to the host planet a dark/bright, split personality

This unique quality of Iapetus had been known for almost 300 years when Arthur C. Clarke used Iapetus as a major plot element in his novel, 2001, A Space Odyssey. [The novel, by the way, differs from the movie in that the Discovery spacecraft went to Saturn in the novel -- even while using Jupiter’s gravity to slingshot Discovery with increased speed toward Saturn. In the film, Discovery only made it as far as Jupiter – apparently because of time and budgetary constraints.] In the novel, Clarke not only took advantage of Iapetus’ unique surface characteristics – and Saturn’s spectacular rings – but even went so far as to prophesize a huge crater-like ring with a dark object in its center.

A bit later (November 14, 1980), the unmanned spacecraft, Voyager I, provided the first clear images showing that Cassini had been right: the leading hemisphere of Iapetus was at least ten times darker than the trailing hemisphere. The leading edge in Clarke’s words was about as light as burnt toast. Or in the words of a NASA press release [2]:

“Iapetus is a two-toned moon. The leading hemisphere is as dark as a freshly tarred street, and the white, trailing hemisphere resembles freshly fallen snow.

“The flyby images, which revealed a region of Iapetus never before seen, show feathery-looking black streaks at the boundary between dark and bright hemispheres that indicate dark material has fallen onto Iapetus. Opinions differ as to whether this dark material originated from within or outside Iapetus. The images also show craters near this boundary with bright walls facing towards the pole and dark walls facing towards the equator.”

“Images from the flyby are available at http://saturn.jpl.nasa.gov/, http://www.nasa.gov/cassini and http://ciclops.org/.”

It is extremely noteworthy that the craters of Iapetus have bright walls facing the lunar poles and dark walls facing the equator. This suggests a roughly equatorial source for the dark material. It might thus be surmised that this implies that the source of the dark material is internal (or at least orbital). In this regard, however, Hoagland [1] quotes a science writer:

…the "exogenous" (outside-source) theory is favored, because nobody can come up with a good explanation for why Iapetus' interior would vomit up such dark material when none of Saturn's other moons shows a trace of it [emphasis added]…

Meanwhile, according to NASA [3]

“Recent observations show that the degree of darkness of the terrain is strangely uniform, like a dark coating was somehow recently applied to an ancient and highly cratered surface. The other half of Iapetus is relatively bright but oddly covered with long and thin streaks of dark. A 400-kilometer wide impact basin is visible near the image center, delineated by deep scarps that drop sharply to the crater floor.” [emphasis added]

Hoagland has also noted “a large (~150 mile diameter), dark, ring-shaped feature… on the side of the moon facing Saturn. In the center of the ring -- almost exactly as Arthur C. Clarke had described it before anyone could have seen it -- was an ‘elliptical white region’… with a black center!” [1] It’s the sort of thing that can really get your attention, particularly after being attracted to the most astounding planet (in appearance) in the solar system, aka Saturn with its incredible rings.

What is not obvious is why Iapetus has a dark side? What mechanisms, natural or otherwise, are responsible for a satellite with such a distinctive feature? Better yet, why would this occur in only a single moon of the solar system? These questions are the reason for delving into Iapetus’ mysteries… but it will take a bit more detail to map out all of the incredible possibilities.

Inclination

Of all the major moons of Saturn (except for tiny, distant Phoebe), Iapetus has the most inclined orbit. All the other major moons lie essentially in the plane of Saturn’s equator and its rings, and are relatively close to the planet.  This includes all of the moons from Mimas (with an approximate 250 mile diameter) to Titan (with a diameter of ~3200 miles). The rings themselves, i.e. the trillions of particles making up the rings -- are of course in orbit in the planet of Saturn’s equator. [Several of the smaller “moons” – actually mere remnants and/or rocks have higher inclinations, but these may actually be explained by some of the more speculative explanations. See below.]

Iapetus, with a diameter of slightly more than 900 miles, has an orbit tilted at 15 degrees to these other orbits and lies more than 2 million miles away. The latter distance is very nearly 60 Saturn radii – which is a mystery in and of itself. For the moment, however, we must address the mechanism that yields a satellite in an inclined, and yet very nearly circular orbit.

The official “party line” of the creation of planets and their satellites is the “nebular model” wherein the swirling ingredients of a solar and/or planetary system slowly condense from an original cloud of interstellar gas and dust. In general, this means that frictional forces and mutual gravitational attractions tend to “warp” the orbits of the forming planets and/or moons into the general plane of all of the forming objects. High inclination orbits are not readily obtainable from this picture.

In the case of Saturn’s third largest moon, Iapetus’ high inclination cannot be easily explained by the nebular model. Instead, one must resort to such ad-hoc solutions as catastrophic collisions and/or interactions with other proto-moons or errant objects. And while this might explain the anomaly, the proposed alternative is viable primarily because of a lack of a better explanation. Of course, if Iapetus was an artificial satellite, finding it in such an odd orbit – as compared to other similarly sized moons of Saturn – solves the problem rather neatly. But for the moment, the collision/interaction theory is the best we can obtain from mainstream science... despite its inherent problems.

Circular Orbit

Equally “coincidental” is the shape of Iapetus’ inclined orbit, and its curiously precise distance from Saturn. On the one hand, Iapetus’ orbit is very nearly a perfect circle, the orbit having an eccentricity of only 0.0283 – i.e. its orbit departs from a perfect circle by slightly less than 3%. Earth’s Moon, by comparison has an eccentricity of 0.0549, or almost twice that of Iapetus.

On a planetary scale, Pluto – recently demoted to the status of “dwarf planet” – and Mercury also have high inclinations (>17 degrees and ~7 degrees, respectively) with respect to the other planets whose inclinations are far smaller. But Pluto and Mercury also have highly eccentric orbits (~0.246 and 0.206, respectively, as compared to 0.007 to .093 for the rest of the planets).

For Iapetus, the combination of a low eccentricity and a high inclination is unlikely to have resulted from the “random chance” of collisional events. Added to this is the fact that Iapetus’ mean distance from Saturn equals 59.091 times Saturn radius.

The tendency of satellites and planets to follow geometrical rules in finding their orbits has been well established by John Martineau in his Book of Coincidence. In this regard, 59.091 is sufficiently close to 60, that one might conclude that the latter distance was the original distance, and that Saturnian/Solar tides and other forces over long periods of time resulted in the difference. This would also explain why the planets depart slightly from the relatively precise mathematical relationships between their orbits. It might also explain why the Moon’s mean distance from the Earth (238,840 miles) is 60.313 times the Earth’s mean radius of 3,960 miles.

[Another Saturn-Earth connection is that the relative orbits of the two planets can be compared with one another by the use of a thirty pointed star. If Saturn's orbit is defined by the outer points of the stars, Earth's orbit is traced by the inscribed circle. Incredibly, the same relative sizing is seen in comparing the two planet's relative size. This can be seen visually in the Book of Coincidence link.]

What is significant about 60 as a multiplier? On the one hand, 60 is a tetrahedral number that suddenly appeared in the Sumerian civilization roughly 60 centuries ago. It thus correlates with the hyperdimensional physics which postulates that a tetrahedron within a sphere would have common points at 19.5 degrees of latitude of the sphere – which in turn leads to the location of Neptune’s blue spot, Jupiter’s red spot, Mars’ Olympus Mons volcano, and Earth’s Hawaiian volcano – as well as Earth’s Teotihuacan ruins.

It is highly noteworthy that the sizes of both Saturn and Iapetus, Iapetus’ distance from Saturn, it’s eccentricity, and orbital inclination are all, allegedly, independent variables. In other words, there is no a priori reason for them to be related, or mandated by any current theory of satellite formation. If on the other hand, the “coincidental” interrelatedness is not simply random… Then other theories must be formulated.

Shape

Then there’s the shape of Iapetus! It’s not like Iapetus is “out of shape”, but rather that it departs significantly from the expected spherical shape.

For planets and moons of a certain size and density, mainstream science expects gravity to work its magic and thereby create a nearly spherical shape. This shape is subject to centrifugal forces – which in turn depend upon the rotational speed of the moon or planet and which can cause a slight flattening of the poles. For example, the Earth is slightly oblate because of its rotation every 24 hours. Iapetus, however, rotates at a very leisurely 79 days, making the effect of centrifugal forces in flattening the poles practically nonexistent. Iapetus should be by most standards pretty much a sphere – not unlike Ganymede, Europa, Titan, Io, and all the other more traditional satellites.

[It should be noted that smaller moons – those with considerably less gravity and mass – are often irregular in shape, and are in fact referred to as “Irregulars.” In many respects these Irregulars are more likely fragments of larger objects. [See below.] The Irregulars account for the massive population explosion of known and discovered satellites of Jupiter and Saturn that now have, respectively, 63 and 57 total moons thus far. For those who think there may be a competition here, it’s important to note that Saturn currently has the pole position in that the Cassini space probe is in the Saturn neighborhood and discovering new moons on a regular basis. Jupiter (and Al Gore) will have to wait a long time for a recount.]

A first impression of Iapetus is that it has been slightly squashed, on the order of 50 miles – i.e. the poles are about 50 miles closer to the center of the moon than they would be had Iapetus been a perfect sphere. This squashing can be compared to Iapetus’ diameter of roughly 900 miles (leaving a squashing percentage of about 5%). This in turn can be compared to Earth's relatively high rotational speed and a squashing percentage of 0.34% (i.e. 27 miles out of 7927).

But the shape of Iapetus -- or more accurately, its geometrical configuration -- is far more interesting. For example, in Wikipedia’s article [4] on Iapetus -- which is being continually updated with new information from the Cassini Huygens mission – it notes the following:

“Furthermore, the overall shape of Iapetus is neither spherical nor ellipsoid—unusual for a large moon; parts of its globe appear to be squashed flat, and its unique equatorial ridge [see below] is so high that it visibly distorts the moon's shape even when viewed from a distance. Scientists are currently unable to describe Iapetus's shape perfectly as the Cassini probe has not yet imaged its entire surface. Current triaxial measurements of Iapetus give it dimensions of 747.1 × 749 × 712.6 km, with a mean radius of 736 ±2km.” [emphasis added]

These measurements in miles become: 464.25 x 465.4 x 442.8 with a mean radius of 457. What is incredible is that in the images returned by the Cassini space probe from a distance of ~77,000 miles, one can actually see with the naked eye a series of straight lined horizons.

From a cross sectional viewpoint, one can see that within the range of measurement error, each of the flat horizon segments form with the two radii an equilateral triangle – with three perfect angles of 60 degrees. (There’s that 60 again!) If further measurements keep up this trend – and it would be actually surprising if they did not – then the cross sectional view of Iapetus becomes a rather precise six-sided figure, a hexagon!

Hexagons are among other things one of the primary building blocks of strong and stable structures – just ask any honeybee (but ask nicely as they can have quite a stinging reply!). What is astounding is that Iapetus’ host planet, Saturn, is currently (and has for the last 27 years) been showing its own hexagon at its north pole. Not surprisingly, this “Hexagon on Saturn mystifies astronomers” [5]

Nature.com [6] – always first on the scene of any new astounding phenomena (rather like ambulance chasers) – has been quick to point out that a bucket of water spinning at a rate of one to seven revolutions per second can create “shapes (holes in the form of stars, squares, pentagons and hexagons) in whirlpools of water in a cyclindrical bucket.”

Of course, the Nature bucket was not 25,000 kilometres across or large enough to fit four Earths inside it – nor does the pole region of Saturn constitute a cylindrical bucket. But hey, the physical principals are still the same, right? Well, maybe. Extrapolations from the micro to the macro (and vice versa) do have a tendency to create wholly different results. One example is metals such as gold where the process of creating smaller and smaller clusters of elements result in the extraordinary results of Microclusters, where characteristics such a conductivity slowly fade away. Accordingly, extrapolating from the Nature bucket to the pole region of Saturn can be risky at best.

It may be true that Saturn’s giant polar hexagon is a perfectly natural phenomenon. It may also be true that something else highly significant is happening. Meanwhile, Nature’s next mission (should they choose to accept it – and later disavow any knowledge of it… hopefully before their much used tape self-destructs) will be to spin a sphere and through some natural process create a hexagonal shape from the sphere – and thereby duplicate just a bit closer the observed features of Saturn and/or Iapetus!

In the process of course, one will have to consider the mass, density, and homogeneity (or lack of the latter). There is, for example, absolutely no justification (other than to simplify the mathematics or conceptual view) in assuming that the mass of Iapetus is distributed uniformly. In fact, the far greater probability is that the moon is decidedly non-uniform (just as the Galilean satellites show notable variations in structure).

It might be pointed out at this juncture that the Earth’s moon has an average density of 3.34 (i.e. 3.34 times the density of water). This suggests a rocky object, but despite the tensile strength of rocks, the moon’s own gravity has crushed it down to an almost perfect sphere (as seen from Earth) measuring some 2,160 miles across.

By contrast, Voyager measured Iapetus’ density to be about 1.21 – only slightly denser than water. Given the likelihood of some rocks in the mix during Iapetus’ formation, this would suggest a primarily water body – and with relatively little tensile strength to resist the gravity of Iapetus to create a spherical body. Water is, in fact, a common ingredient in selected versions of Saturn and Jupiter’s moons – from Europa and Mimas to Enseladus, Tethys and Rhea (the latter four moons that of Saturn).

Rhea, for example, is roughly the same size as Iapetus (Rhea’s diameter of 1,528 km as compared to Iapetus’ diameter of 1,436 km), with a mean density of 1.23 (comparable to Iapetus’ 1.21). Rhea is notably closer to Saturn than Iapetus, but Rhea nevertheless shows no deformities in its spherical surface of any significance. It is conjectured that “Rhea has almost homogeneous interior (with some compression of ice in the center)…” Furthermore, “The triaxial shape of Rhea is also consistent with a homogeneous body in hydrostatic equilibrium.” [7] Rhea is, in fact, pretty much what one might expect of a moon of Saturn.

Rhea also has a synchronous orbit about Saturn, making the round trip every 4.5 days or so. Meanwhile, Iapetus, located almost 7 times further from Saturn than Rhea, has a 79-day rotation, such that any centrifugal force on Iapetus would be relatively insignificant in terms of deforming the body. And if it didn’t occur on Rhea… why is Iapetus’ shape approximate a hexagonal geometry? Better yet, how does a liquid center result in a rocky crust with six flat horizons!

One possibility, of course, is that the assumption of consistency in the make up of the moon is wrong. One could, for example, incur the same density with the use of high density materials with substantial tensile strength on the outer portions of the moon, while the interior was composed of notably less dense materials – even low density liquids or even gases. The latter of course raises the specter that Iapetus may have significant voids or hollow spaces within its interior.

Okay. Now it’s getting a bit scary… and we haven’t even mentioned “The Ridge” yet.

The Ridge

Okay, now we’ve mentioned it.

According to Hoagland [1], there's a: "…long narrow ridge that lies almost exactly on the equator of Iapetus.” Or as NASA said – in two different instances:

“What has happened to Saturn's moon Iapetus? A strange ridge crosses the moon near the equator, visible near the bottom of the above image, making Iapetus appear similar to the pit of a peach. [3]

“One of these features is a long narrow ridge that lies almost exactly on the equator of Iapetus, bisects its entire dark hemisphere and reaches 20 kilometers high (12 miles). It extends over 1,300 kilometers (808 miles) from side to side, along its midsection. No other moon in the solar system has such a striking geological feature. In places, the ridge is comprised of mountains. In height, they rival Olympus Mons on Mars, approximately three times the height of Mt. Everest, which is surprising for such a small body as Iapetus. Mars is nearly five times the size of Iapetus. [2]

For practical reasons, you really need to see it. Wikipedia’s version is one of the better images – especially for an enlargement. Accordingly, one should visit Wikipedia’s Iapetus. Just hurry back, for all the information that Wikipedia won’t be providing.

Photomosaic of Cassini images taken Dec. 31, 2004, showing the dark Cassini Regio, several large craters, and the newly discovered equatorial ridge. [8]

According to the 2005 Lunar and Planetary Science Conference ISS Team paper, covering the last six months of Cassini’ observations of Iapetus – as reported by Hoagland [1]:

…these data led to the discovery of the enigmatic "bellyband" of Iapetus, a ridge or chain of mountains that follows Iapetus' equator precisely over at least 1300 km [3]. The highest measured peak rises ~20 km over the surroundings, or ~28 km over a reference radius of 718 km [10]. However, as in Voyager data [8], a good reference ellipsoid cannot be found because of the unusual irregular shape of Iapetus…

The ridge coincides with the faint equatorial streak observed in the October [2004] and even July data. The slope of the southern flank achieves a gradient of up to 20°, the northern flank ~30°. The ridge itself appears to be located on a broader bulge, extending a few hundred km in southern and northern directions [emphasis added]…”

… the ridge itself appears to be located on a broader bulge, extending a few hundred km in southern and northern directions [emphasis added]--”

In response to this report, Hoagland [1] notes that,

“There is no viable geological model to explain a sixty thousand-foot-high, sixty thousand-foot-wide, four million-foot-long “wall”… spanning an entire planetary [or lunar] hemisphere… let alone, located in the precise plane of its equator! Scaled according to the surface gravity of Iapetus – which is only 1/40th the strength of the surface gravity of Earth! – a similar skyscraper [as the Dubai tower scheduled for completion in 2008] on the 900-mile-wide moon of Saturn could reach up 15 miles. A “wall-like” structure -- as wide as it is tall – because of strong lateral support, could reach far higher in such a weak gravity field.

“Based on these early measurements by the Cassini Team and certain structural considerations of the artificial model, it seems highly likely now that “the Wall” is NOT simply a feature sitting on Iapetus’ surface – as many have speculated... extending more than 12 miles above the surrounding plains -- but rather—

“The remains of a deep, massive “equatorial reinforcing ring” -- which was used to literally join the two hemispheres of this “artificial moon” together!

There are even as many as three, parallel bands arcing around Iapetus’ surface and parallel to the equatorial ridge. We’re now into the completely unfathomable. Except, of course, there are always those who can fathom anything. For example…

We can look to New Scientist to explain everything:

“The mysterious equatorial ridge on Saturn's moon Iapetus is either a fossil ring system that fell to the surface, or a pile up of crustal rocks formed as the satellite changed its shape. These are the latest theories from planetary scientists.” [As of 9/4/2006] [9]

Great! What we have here is two competing theories, with a fair amount of effort being expended in the New Scientist article to explain why each competing theory is wrong! In fact, giving full faith and credit to New Scientist, the explanations as to why each of these two competing theories is wrong are so convincing that one suddenly realizes, “Hey! Maybe they’re BOTH wrong! Maybe what we need is a third, actually plausible theory!”

But before we make that leap, perhaps we should take note of… you guessed it… a few more anomalies.

Surface Features

Lunar craters are by their nature roughly circular. However, a detailed, greatly magnified close up image of the surface of Iapetus seems to suggest square-shaped indentations. In fact, the surface is composed in some areas of a pattern of back-to-back, square “craters”. Furthermore, according to Hoagland [1],

“The rectilinearities run precisely north/south, east/west… The effect is closer to an “aligned, repeating architectural relief. They are of ‘standard-width’, right-angle walls, and dozens of ‘box-like’ rooms and buildings contained within those walls.”

This surface feature, however, is interrupted in a rather dramatic fashion by two “ring-shaped features” – that could in fact be craters. These ring craters, however, are located at the two ends of the dark material that covers two-thirds of Iapetus, and where the dark material forms a relatively precise ellipse.

“In traditional planetology, these circular 'impact basins' are attributed to explosive asteroid or cometary collisions (sometimes the resulting excavation later partially refilling with upwelling internal lava, producing 'ring basins' around the central impact uplift). Such features have been photographed over the years on a variety of solar system objects, and come in a variety of sizes -- all attributed to these celestial objects – even ones only a few miles across -- striking at hypersonic velocities, releasing their devastating kinetic energy on impact. 

“The problem with this random, external explanation for Iapetus is that both ring-features are the same size… both lie on the Iapetus’ equator… and both are located (the shortest distance) ~120 degrees apart -- precisely one third of the satellite’s circumference from each other… one 'tetrahedral” angle!'

“…the odds of two similar-sized objects randomly striking such a satellite twice, on the equator, and precisely 120 degrees apart -- thus producing two 'coincidental' matching 'ring basins' -- are infinitesimal. 

“These extraordinary odds are compounded, of course, by the fact that the mysterious 'dark ellipse' across the leading hemisphere stretches 240 degrees the other way around the 'planet' -- which is, of course, two 'tetrahedral angles'… The ellipse now begins and ends neatly at the two 'rings'– indicating that they are somehow 'involved' with its creation. 

“This all argues persuasively for an internal source for both the dark ellipse… and the rings themselves.”

“Finally, it can be no accident that the Great Wall neatly bisects this ellipse… and, straight as an arrow, runs for 240 degrees… connecting both strange rings!” [1]

Radar

One standard technique for studying a satellite is to use radar, even on moons which are mostly water ice. The apparent ice on Iapetus, however, is significantly less reflective than the other Saturn ice satellites, and furthermore, the radar sees Iapetus as a uniform blip – implying no difference between the light and dark sides.

Hoagland [1] has suggested a correlation between Iapetus’ radar characteristics and the technology behind “stealth” aircraft. The latter’s ability to hide from radar is based on two properties: the aircraft’s coating and its geometry. One could, for example, use coatings such as ammonia/ice combinations to absorb the shorter wavelength radar signals. If this is then combined with a geometry that does not directly reflect the radar beam, then stealth becomes very real. This is why the modern F-117 aircraft looks more like a collection of flying pyramids, instead of an apparently more aerodynamic shape.

The reasoning for Iapetus’ “anomalously low radar reflectivity” can then be traced to the possibility of its surface coating and surface geometry. It is not a great leap from there to the speculation that the low radar reflectivity is intentional, i.e. that there was some form of intelligent design at work for the purpose of “hiding” or “highlighting” Iapetus.

Importantly, it should be noted that the idea of a “stealth satellite” such as Iapetus does not make much sense for the simple reason that the satellite can be seen in the visible spectrum easily enough. If this fact is then combined with a low radar reflectivity, Iapetus-- instead of becoming less noteworthy to the passing intelligence -- suddenly becomes highly intriguing. Instead of hiding as a natural moon or object, which is what any cautious spacefarer might do, this “moon” suddenly becomes an object worthy of more study simply because of the low radar reflectivity. This constitutes the antithesis of stealth, and more like a billboard for attracting attention.

Age

There is a very strong tendency for mainstream astronomy -- and its associated politics -- to rely on the number of craters and other evidence of celestial collisions as a means of estimating the relative age of different planets and/or moons. In fact, the current crop of “surface ages” in the solar system is ultimately dependent upon a benchmark provided by the Earth’s Moon. There is of course no justification for assuming the age of the Moon is correlated with anything else in the solar system – while solar system wide events might have occurred, there would also likely be isolated incidents as well. Furthermore, a quick comparison between the near and far side of Earth’s Moon would lead to the ludicrous conclusion that the two sides of the Moon are of enormously different ages!

The questionable aging question is then compounded by a long standing assumption by modern astronomy that the...

“wide-spread evidence of extensive cratering – from the planet Mercury to the moons of the outer solar system – is due to a single episode of ‘late heavy bombardment’, from a then newly-formed population of asteroids and comets ‘in the beginning’ – debris literally left over from the solar system’s nebula formation, 4.5 billion years ago. And that this impacting population – after initially, steeply declining – has been almost constant (or very gradually) waning over the ensuing billions of years.” [1]

Part of the reason for such an assumption is the removal from the public’s mind that if celestial bombardment happened billions of years ago, then there is no concern that other episodes might happen next year, or this coming Tuesday. The collision of the Comet Shoemaker-Levy with Jupiter makes it clear that celestial “events” do occur in modern times – despite earlier estimates of the almost infintestimal possibility of such an event occurring. More recently, there has been a strong surge of interest in “Near-Earth Objects”. Clearly, the motivating concern of the latter surge is that an object just might drop by totally unannounced -- and parenthetically, eliminating life as we know it. The fact that the concern might be justified more on the basis of finding a way in which to increase research funding rather than for the creation of an early warning system to save billions of human lives... does not eliminate the fact that modern day celestial events can occur.

The circumstance of the Sun Standing Still is one case in point. There is also the very intriguing possibility that Earth’s Moon is a relatively recent addition – even to the extent that ancient legends speak of a time before the Moon took up residence roughly 250,000 miles from the Earth. The fact of the matter is that estimates of age based on some very weak assumptions are likely to be virtually indeterminate.

In the case of Iapetus, the extensive “shoulder-to-shoulder” cratering does not necessarily imply that the satellite’s surface is extremely old or dating back billions of years. In fact, one would on a rational or logical basis have to assume that the apparent differences between satellites of Saturn or the entire solar system are due less to their relative ages, than due to the differences in their histories. The problem, of course, is that the differences in histories allows for much more intriguing -- and scary -- possibilities.

One of these possibilities is that the traditional nebula model of the solar system may be catastrophically wrong [pardon the pun], and that the history of the solar system may instead be enormously more interesting. There may have been, for example, cycles of periodic, catastrophic destruction and creation of new worlds. It is entirely possible, if not entirely reasonable, to assume that there have been numerous entrances and exits from the solar system stage.

The possibility of a former planet located between the planets Mars and Jupiter in the asteroid belt is one case of a possible exit. For entrances, there is the mythology of Uranus being usurped by Saturn, and later Saturn being usurped by Jupiter. Does this imply that Saturn and Jupiter were relative latecomers (Jupiter being clearly the later arrival), but whose arrivals created more than just a minor stir? There is, of course, the myths of Venus being born out of the side of Jupiter. Do these myths and other factors explain in part such anamolies as Uranus’ poles being inclined at a huge angle of 98 degrees from the plane of the solar system?

Tom Van Flandern, an expert in solar system celestial mechanics, has provided compelling evidence to support the theory of a solar system undergoing a history of the periodic, catastrophic destruction of whole worlds and the creation of vast clouds of orbiting debris, the latter that ultimately wind up hitting all the other planets (and their moons). [1] Clearly such a model implies that the surface cratering of Iapetus cannot be used reliably to calculate its age.

September 10, 2007

A whole slew of questions about Iapetus are obviously begging to be answered. The good news is that come the fall of 2007, much of what we now know or can speculate about Iapetus may be confirmed, repudiated, or partially supported. For that is when Cassini will be making an up close and personal flyby of Iapetus – and where, hopefully, the space probe (with NASA’s kind indulgence) will be providing hundreds of new images.

“Cassini's next close encounter with Iapetus will occur in September 2007 [the 10th, one day before the Coptic and Ethiopian New Years and that “other date”]. The resolution of images from that flyby should be 100 times better than the ones currently being analyzed. The hope is that the increased detail may shed light on Iapetus' amazing features and the question of whether it has been volcanically active in the past.” [2] [emphasis added]

In other words Cassini will be within 800 miles of Iapetus -- instead of the previous closest approach (on which the other images were taken) of 77,000 miles. Thus, we’re talking about some truly stellar photographs! [pardon the pun]

On the other hand, science is all about predictions, followed by observations to see if the predictions pan out. Accordingly, this is where things really get interesting – and into such realms where NASA, Wikipedia, and other mainstream publications might be very, very hesitant to tread… at least for purposes of public consumption. In other words, it’s Speculation Time!

Speculation

Occam’s Razor says that "All things being equal, the simplest solution tends to be the best one." If that's the case, the far more obvious and simpler explanation for the anomalies discussed thus far is that Iapetus is not simply a naturally occurring object or moon of Saturn, but instead is either an artificial satellite or a natural satellite which has undergone extensive artificial modifications.

Iapetus may in fact be…

“a 900 mile-wide, manufactured, ancient world-sized spaceship… created under 1/40th terrestrial gravity according to a fractally apparent, ‘tetrahedral’ pattern!”

“These are the shattered, blasted remnants of an ancient, almost incomprehensible science and technology… stark, surviving evidence of a “super-engineering” that once held together an entire world… and for some reason, placed it in the Saturn system.” [1]

Such an explanation can easily and straightforwardly explain the following observations:

  • The incredible feature of having one hemisphere black and the other white,
  • The intriguing anomalous inclination and nearly perfect circular orbit,
  • The unique geometrical (hexagonal) shape of the satellite,
  • The strange surface features and the low radar reflectivity,
  • The low density of the overall satellite, combined with the higher density of the surface – in particular the equatorial ridge which rises up 12 miles above the surface of Iapetus, and
  • The equatorial ridge itself, which could be related to the structural characteristics of the surface, or to a mechanism that might provide propulsion for the satellite.

Obviously, we’re talking about extraterrestrials and/or intervention by an intelligence in the natural process of the solar system’s evolution. And while angels might be construed as being extraterrestrials (by definition), there has not been a lot of evidence presented where the angels of various religions have been heavily involved in major construction projects on and off world. Accordingly, we may be talking about interventions that carry with them one or more extraterrestrial agendas.

Richard Hoagland has provided an enormously entertaining treatment on this very subject at his Enterprise Mission website, under the guise of Moon With a View. [1] While Hoagland’s website is highly recommended for the intrepid truthseeker, the reader should be warned that as of the date of this essay, there were six, long parts to the treatment. Thus the reader should expect to spend a couple of hours reading and marveling – not to mention checking references for the more skeptical crowd. There are, of course, some marvelous graphics.

For our purposes, if we assume that Iapetus is either partially or wholly artificial – and constructed/modified by beings other than humans (i.e. extraterrestrials) – then it follows that we must inquire about the nature of the satellite. I.e., what’s it for? There are several possibilities.

Ark

One speculation is that in the midst of all the planetary destruction allued to in the Van Flandern theory (see above) – not to mention Douglas Adam’s assumption of it being routine to destroy a planet to make way for an interstellar expressway – is that a civilization residing on a planet scheduled for demolition might, if they had the resources, decide to go elsewhere, a new locale hopefully less blessed by exciting times. The key would be a world sized (depending upon time and resources) ark, one capable of transporting all or a significant portion of that civilizations’ citizenry and resources.

One might also suspect that many if not all of the satellites at high inclinations in the Saturn (or even Jupiter) system are remnants of destroyed ancillary spaceships. This would make sense that in constructing an ark, several arks would be a much better bet. The advantages of number are the same as for Columbus who sailed in 1492 in three ships: if one encounters trouble, the others might still make it. The key is not to place all of one’s eggs in a single basket. [This reasoning applies to several of the other scenarios as well.]

One notable argument against the ark scenario is that once the ark arrived in Saturnian space, what would it do next? Why not settle on something a bit more stable? The fact that Titan has an atmosphere might suggest that some terraforming might have been in the offering has some appeal. But what about Earth? Wouldn’t a group of pioneers have found the third planet from the sun appealing? Assuming, of course, that Earth existed in roughly its present state at the time of the ark!

Hoagland [1] at first makes a case for the ark possibility – as well as for the idea that Iapetus might have been a warship – but then because of numerous apparent contradictions for either of these two scenarios, decides against them. For our purposes, the ark and/or warship scenario seems the least likely possibility.

Exploration

Any race with the technology and motivation to explore the universe – or even just the solar system or local galactic neighborhood – would almost certainly not do so in an obviously artificial spacecraft. The incredibly sleek ships of science fiction fame just don’t make sense when one is going into uncharted environs where the locals might be just a bit more defensive than one might hope for. Furthermore, when you’re going for a long-haul exploration, you really need to take a lot of things with you. This includes a large number of individual beings in addtion to a whole slew of kitchen sinks. What is not recommended is a small craft with a half dozen members, who will probably find all manner of reasons to learn to hate one another, and where the death of one would be devastating to the mission.

The difficulty with the exploration theme is what happened to the pioneers? Did they run into hostilities, have the bad luck of an interstellar collision, or just drive one another bonkers? Why would they leave their home away from home out in the environs of Saturn? Did they simply forget where they had parked it? Probably not. And therefore the best reason to dismiss the exploration scenario is that Iapetus is still here.

In fact, the best argument against the ark, warship, and/or exploratory vehicle scenarios is that the end result of either scenario would have to be one of catastrophic failure in order to qualify as a possibility.

Sign Post

Donald Goldsmith and Tobias Owen (the latter, the NASA discoverer of “the face on Mars!”) wrote of Iapetus in The Search for Life in the Universe (1980):

“This unusual moon is the only object in the Solar System which we might seriously regard as an alien signpost - a natural object deliberately modified by an advanced civilization to attract our attention…” [1]

Of all the possible scenarios of the artificial construct or modification of Iapetus, the one striking feature of this satellite is the number of… well… striking features. Begin with an extraordinary planet, Saturn with its spectacular rings and which is clearly the most prominent object in the solar system. Follow that with a satellite that blinks on and off in its orbit, has a distinctive coloration like nothing else seen, has anomalous radar reflectivity as well, has surface features for those able to obtain relatively close images, combines a high inclination and circular orbit, and so forth and so on. All of these distinctive elements serve a common goal that of motivating any intelligence worthy of the name to look much, much closer at Iapetus.

Whether this flashing sign is intended for the inhabitants of the local solar system or for travelers entering from interstellar space, Iapetus is the most distinctive neon sign one is likely to encounter. Even if its artificiality is limited to being nothing more than an alien signpost to get one to drop by and look for clues for the next part of the scavenger hunt, it does serve that purpose spectacularly.

Arthur C. Clarke, the great science fiction writer who was above all a scientist (albeit with a creative imagination), clearly recognized the potential for Iapetus. In the case of 2001, A Space Odyssey (a fictional novel in case one is tempted to forget), this signpost was more of a subway entrance sign. The latter, of course, is by far the most speculative suggestion (i.e. the scenario with the least amount of evidence to support it). However, in the process of taking a much closer view, it is clearly the most exciting possibility.

Spiritual Resort

Another concept – one that shows some marvelous creativity – is the idea proposed by Richard Hoagland [1], i.e. “A Moon With a View.”

In short order, one can note that Iapetus is the only satellite with a spectacular location for purposes of viewing both the ringed planet and all of Saturn’s other moons. Better yet, it keeps this perspective for its entire orbit – with the only significant variation being that the rings are seen on edge twice in the 79 day orbit (but which just makes the view all the more intriguing).

As Hoagland notes, Iapetus can be seen as “an artificially-modified, carefully crafter ‘designer world… to serve as another highly specialized purpose: as a vast, orbiting ‘hotel’.” [1] While its rates are undoubtedly astronomical [pardon the pun], the fact remains that its ability to inspire and motivate would be very substantial. It’s really the place to be for the jet set (in fact there’s no other way, currently, to get there). It also allows for the classic jest, “the place has great food, but absolutely no atmosphere”.

But designer hotels might offer other possibilities as well. From an inspirational point of view, Iapetus might also provide for spiritual purposes as well. It could quite literally be the destination for ancient pilgrims – whether from this solar system or elsewhere. Keep in mind that from the view point of Iapetus, Saturn, its rings and moons, would create a spectacular scene, more than 140,000 miles across. It would provide a spectacle “eight times as large as a full Moon rising over Earth’s horizon!”

“Far less technological peoples, in our own immediate past (on this one planet), have repeatedly expended prodigious (and equally baffling, to anthropologists and archaeologists) social and engineering efforts – from Stonehenge to Giza... to Chaco Canyon -- to immortalize remarkably similar religious and spiritual concepts. Again, we have innumerable precedents for such spiritual “mega-engineering” on this planet – sacred architecture that, according to many independent researchers, has intimately encoded these same “sacred" geometry and hyperdimensional principles in the most mysterious, surviving wonders on this world.” [1]

"The question [that] has always hovered over these amazing ruins, all around the world – “From how far back in time… and from where… did such ‘advanced’ ideas, and incredibly sophisticated knowledge, enter into human consciousness?  And from whom?”

Seed Ship

The latter question raises the possibility of a final (as of press time) scenario. That the whom of which we wonder might in fact be our progenitors. This is best described in Clarke’s 2001, A Space Odyssey as the “progenitors of the human race” who in the finale of the novel, return the ultimate astronaut, Bowman, to Earth as “…the latest agent in humanity’s continuing managed evolution.” [emphasis added]

The curious but ironic twist is that Iapetus is named after a Titan – the son of Uranus and the father of Prometheus and Atlas (the latter two who are often claimed to be the “fathers of mankind.” In this sense, Iapetus was an ancestor… a progenitor… of Homo sapiens sapiens. In this sense, of course, it is not necessary to begat the next generation in the traditional manner, but only to provide the seed.

On top of everything else, Saturn was worshiped by the ancients as the “God of Seeds”. This worship of Saturn stemmed from the time Saturn was for all mankind the supreme god… until “Jupiter drove Saturn away from its place in the sky.” [10]

“If it is true that the Earth passed through… gases exploded from Saturn, it should not be entirely excluded that germs were carried together with meteorites and gases and thus reached the Earth. The scholarly world in recent years has occupied itself with the idea that microorganisms – living cells or spores – can reach the Earth from interstellar space, carried along by the pressure of light waves. The explosion of a planet [or an explosion in the vicinity of that planet] is a more likely method of carrying seeds and spores through interplanetary spaces.” [11]

Iapetus may have been a seen ship, sent from elsewhere and upon arrival in the local area allowed to disseminate its cargo far and wide. Earth managed to get into the flight path of the seeds, and served as a wonderful place to initiate new forms of life.

Hoagland [1] has noted that,

“It is now known that for most of the history of Earth, the most sophisticated form of life was simple algae – ‘pond scum.’  From about four and a half billion years ago up until about six hundred million years before the Present, a relatively narrow range of algae were the most advanced organisms living anywhere on the planet. 

“Then, at the boundary between the last two great geological epochs -- known as the great ‘Pre-Cambrian/ Cambrian transition’ -- there was a veritable ‘explosion’ of much more complex life, which formed the pattern for the development of all the future ‘kingdoms,’ ‘phyla,’ ‘genera,’ ‘families’ and ‘species’ that we now recognize on Earth.  This so-called ‘Cambrian Explosion’ is without doubt the single biggest mystery of life on Earth -- Save, of course, for the even more mysterious appearance of Life itself.

"Why, for literally billions of years, was Earth home to only an extremely narrow range of microscopic cyanobacteria, some organized in great algal mats (below) called ‘stromatolites’?  And then, in the space of less than 5 million years (as judged by the latest evidence) – BANG!! – every form of life currently appearing on Earth suddenly emerged?  In fact, this profound mystery is termed by some biologists “the Big Bang of Evolution.” [1]

“Scientists have also long been puzzled by its abruptness, and the apparent lack of obvious predecessors to the Cambrian fauna.” [12]

“…roughly fifty separate major groups of organisms or "phyla" (a phylum defines the basic body plan of some group of modern or extinct animals) emerged suddenly, in most cases without evident precursors (Gould, 1989). This radiation of animal phyla is referred to as the Cambrian explosion. [12]

A critical aspect of the Cambrian Explosion is that the proliferation of the forms of life was absolutely incredible! For example, in the early beginnings of the Cambrian Era, there were by “roughly fifty” phyla. Today there are approximately 35 phyla.

“The best known animal phyla are the Mollusca, Porifera, Cnidaria, Platyhelminthes, Nematoda, Annelida, Arthropoda, Echinodermata, and Chordata, the phylum to which humans belong. Although there are approximately 35 phyla, these nine include the majority of the species.” [13]

The key factor is that out of the pond scum arose a wide variety of animal phyla – just the sort of thing that an intelligently planned seed ship might prefer, i.e. animals instead of pond scum (aka football players instead of leaching lawyers). Furthermore, the seed ship could not always be certain of the host planet’s conditions, so that 50 or more phyla were dispatched, but within a few million years, a forth of them might have already paid the price of survival of the fittest. It’s not that any particular phylum was better than others. It’s just that Earth’s phylum, Chordata, was the one to begin wondering about Iapetus.

What we’re alluding to here is the possibility that Earth’s burst of creative life stemmed from the arrival of the seed ship, Iapetus, which in turn may have been just one portion of an ancient, extraterrestrial program to convert any number of suitable planetary candidates in parts or all of the galaxy’s outlying solar systems to become hosts to the origin and evolution of life! And not only life itself – certainly a noble goal in itself -- but conscious, intelligent life, the kind you might be willing to bring home to meet mom! Now there’s a divinely inspired [pardon the pun] mission!

The idea of Panspermia or Exogenesis is not new, and is considered in some detail by Wikipedia, as well as other webpages on this website. But the ideas that what we have here is directed exogenesis or that the intended panspermia is designed to create intelligent life is somewhat more speculative.

For our purposes, it is important to note that the alien signpost, the moon with a view, and the seed ships could easily be all part of the same cosmic package. Create an interstellar seed ship with a huge proliferation of seeds, send it and duplicate ships to a wide variety of potential host planets, allow time to bring forth intelligent beings (the potential for intelligence possibly being built into the seeds), provide a winking neon sign to attract any and all intelligences resulting (from the seeding program) -- specifically intelligences with the technology to discover and then venture to the sign post -- and on top of everything else, have a spiritual and/or moon with a view location just to add to the motivation to go there. And upon our arrival on Iapetus… the next clues to the greatest scavenger hunt ever patiently wait!

What in the final analysis is Iapetus? In view of the fact that the final analysis is not yet upon us – not at least until the tentative final Cassini analysis in the fall of 2007 – such a conclusion would have to be considered premature. But the creative juices are flowing. It’s now just a question of the willingness of NASA to consider all of the possibilities and to communicate them to the world. The problem, of course, is the Specter of Revelations and the fact that NASA may for political, economic, and/or religious (aka anti-scientific) reasons, live up to its acronym, “Never a Straight Answer”.

In any case, only time, Cassini, and other factors will tell. Stay tuned.
