Mars’ Moon Phobos has been analyzed as being one-third hollow according to European Space Agency reports, which has triggered some wild and utterly fascinating rumors and speculation that we’ve featured below.

Radio science result from 2008 Phobos Flyby now accepted for publication:
We report independent results from two subgroups of the Mars Express Radio Science (MaRS) team who independently analyzed Mars Express (MEX) radio tracking data for the purpose of determining consistently the gravitational attraction of the moon Phobos on the MEX spacecraft, and hence the mass of Phobos.
We conclude that the interior of Phobos likely contains large voids. When applied to various hypotheses bearing on the origin of Phobos, these results are inconsistent with the proposition that Phobos is a captured asteroid.
For a Martian moon that is demonstrably “1/3 hollow” … as measured by two totally independent space programs, and separated by ~20 years … under any likely astrophysical formation scenario cannot exist as just a “natural” moon.
The MARSIS radar imaging experiment — according to “inside” ESA sources recounted “a Phobos’ interior filled with ‘cavernous, geometric rooms … right-angle walls … and floors — detectable via the semi-regular ‘structure of the returning, interior radar echoes …’ as they were impressed upon the reflected MARSIS signals ….'”
MARSIS was physically seeing (via this radar) a three-dimensional, totally artificial, interior world … within Phobos; and a “reflection void interior geometry” … which correlated eerily with the earlier (lower-resolution) Phobos “interior gravity tracking data ….”
No natural “space rock” could possibly possess such an enormous range of “natural radar absorbers and reflectors”; nothing “natural” could reflect (or absorb) EM energy that way across so many orders of magnitude.
In other words — the MARSIS radar reflections officially published on the official ESA Phobos website… contained explicit scientific data, from multiple perspectives, which strongly “supported the idea that this is what radar echoes would look like, coming back from inside ‘a huge … geometric … hollow spaceship’
In fact, they were the primary source of the decidedly “internal, 3-D geometric-looking” radar signature.
The concurrence of all three of these independent Mars Express experiments — “imaging” … “internal mass distribution” (tracking) … and “internal radar imaging” — now agreed that “the interior of Phobos is ‘partially hollow … with internal, geometric “voids” inside it ….'”
Meaning that- Phobos is artificial.
SECOND DAILY GALAXY ARTICLE ABOUT PHOBOS BEING ARTIFICIAL
Strangely, the Daily Galaxy did not drop this story — in fact, only five days later they added to it, and posted a newer, sexier and much longer and more detailed version as of June 3rd — just one day before the Australia Spiral!
Are you seeing a pattern developing here? We seem to be spiraling in towards a very real answer!
Here’s a screen capture of the post from their site:
Yes… we now have mainstream media writing up the same information two times in five days — boldly putting out the idea that “Phobos is a 1.5-mile-long, extremely ancient and battered spacecraft!”
Remember — this is what the folks at ESA told Hoagland they had found. They also made it clear that they could use his help to bring this information out to the world. Now we’re seeing them make good on that promise, apparently, with such bold attention being paid to it in the Daily Galaxy.
Check this out (emphasis added):
Some of the more fascinating, and wild speculative theories swirling around the Phobos Grunt Mission at sites like EnterpriseMission.com see it as “the single most important scientific mission in the history of the past half-century of modern solar system exploration ….With Phobos as an ancient solar system relic from an extraordinarly distant, pre-human, apparently solar-system-wide ancient high-tech civilization.One that could ultimately turn out to be directly related to our own.”It is expected that Earth-based ESA stations will take part in controlling Phobos-Grunt, receiving telemetry and making trajectory measurements, including implementation of very long-baseline interferometry (VLBI).This cooperation is realized on the basis of the agreement on collaboration of the Russian Federal Space Agency and ESA in the framework of the Phobos-Grunt and ExoMars projects (see post above).In the late 1950s and 1960s, the unusual orbital characteristics of Phobos led to speculations that it might be hollow.Around 1958, Russian astrophysicist Iosif Samuilovich Shklovsky, studying the secular acceleration of Phobos’ orbital motion, suggested a “thin sheet metal” structure for Phobos, a suggestion which led to speculations that Phobos was of artificial origin.Shklovsky based his analysis on estimates of the upper Martian atmosphere’s density, and deduced that for the weak braking effect to be able to account for the secular acceleration, Phobos had to be very light.The density of Phobos has now been directly measured by spacecraft to be 1.887 g/cm³, which is inconsistent with a hollow shell.In addition, images obtained by the Viking probes in the 1970s clearly showed a natural object, not an artificial one, and the “hollow Phobos” speculations have been relegated to the status of a historical curiosity.However, mapping by the Mars Express probe and subsequent volume calculations do suggest the possible presence of vast caverns within the moon and indicate that it is not a solid chunk of rock but a porous body instead.The porosity of Phobos was calculated to be 30% ± 5%, or a quarter to a third of the moon being hollow, likely in the form of large voids.In a July 22, 2009 interview with C-Span U.S. astronaut Buzz Aldrin said:“We should go boldly where man has not gone before. Fly by the comets, visit asteroids, visit Phobos, a moon of Mars.There’s a monolith there. A very unusual structure on this potato shaped object that goes around Mars once in seven hours.When people find out about that they’re going to say ‘Who put that there? Who put that there?’ The universe put it there.”
