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. From "The Phobos Blog" -- published on March 25th: General , Science 25 March, 2010 17:21 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.

Discover Why Thousands of People are "Jumping" to Change Their Life www.QuantumJumping.com 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.

Phobos is a rubble pile held together by gravity

The particular class of asteroids that share Phobos's density are known as D-class. They are believed to be highly fractured bodies containing giant caverns because they are not solid. Instead, they are a collection of pieces, held together by gravity. Scientists call them rubble piles. Also, spectroscopic data from Mars Express and previous spacecrafts show that Phobos has a similar composition to these asteroids.This suggests that Phobos, and probably its smaller sibling Deimos, are captured asteroids. However, one observation remains difficult to explain in this scenario. Usually captured asteroids are injected into random orbits around the planet that gravitationally tie them, but Phobos orbits above Mars' equator - a very specific case. Scientists do not yet understand how it could do this. In another scenario, Phobos could have been made of Martian rocks that were blasted into space during a large meteorite impact. These pieces have not fallen completely together, thus creating the rubble pile. So the question remains, where did the original material come from - Mars's surface or the asteroid belt? The MARSIS radar on board Mars Express has also collected historic data about Phobos's subsurface. This data, together with that from the moon's surface and surroundings gathered by the other Mars Express instruments, will also help put constraints on the origin. It's clear though that the whole truth will only be known when samples of the moon are brought back to Earth for analysis in laboratories.
Phobos is similar to an asteroid- not hollow.

The six-mile wide Stickney crater dominates this image of Phobos taken by the Viking 1 orbiter. Phobos, gouged and nearly shattered by a giant impact crater and beaten by thousands of meteorite impacts, is on a collision course with Mars. Phobos is the larger of Mars' two moons and is 27 by 22 by 18 km in diameter. It orbits Mars three times a day, and is so close to the planet's surface that in some locations on Mars it cannot always be seen. Phobos is nearing Mars at a rate of 1.8 m every hundred years; at that rate, it will either crash into Mars in 50 million years or break up into a ring. Its most prominent feature is the 6-mile crater Stickney, its impact causing streak patterns across the moon's surface. Stickney was seen by Mars Global Surveyor to be filled with fine dust, with evidence of boulders sliding down its sloped surface. Phobos and Deimos appear to be composed of C-type rock, similar to blackish carbonaceous chondrite asteroids.Observations by Mars Global Surveyor indicate that the surface of this small body has been pounded into powder by eons of meteoroid impacts, some of which started landslides that left dark trails marking the steep slopes of giant craters. Measurements of the day and night sides of Phobos show such extreme temperature variations that the sunlit side of the moon rivals a pleasant winter day in Chicago, while only a few kilometers away, on the dark side of the moon, the climate is more harsh than a night in Antarctica. High temperatures for Phobos were measured at 25 degrees Fahrenheit (-4 degrees Celsius) and lows at -170 degrees Fahrenheit (-112 degrees Celsius). This intense heat loss is likely a result of the fine dust on Phobos' surface, which is unable to retain heat. Phobos has no atmosphere. It may be a captured asteroid, but some scientists show evidence that contradicts this theory.
