Phobos is, in fact--
An "ancient ... ex terrestrial ... very battered ... 15-mile-long"-- Spaceship.
Which now (according to our European sources -- backed up by the actual Mars Express data itself, which you will see more of - below) ESA is about to officially ... publicly announce!
Possibly -- even before President Obama's up-coming ... suddenly-called ... STILL super-secret "Space Summit"--Which is scheduled to take place, within a few days, at the Kennedy Space Center -- personally hosted by the President of the United States of America -- in the middle of an on-going shuttle mission-- STS-131.
Which, turns out to be ... the 33rd Space Shuttle Mission ... to the Space Station ("ISS"). Can you say "the Fix is in" ... for "something?"
Regardless of these "politically symbolic numbers," the primary reason we can be increasingly confident about the outcome of these coming "ESA revelations" -- is because of the strength and depth of the published scientific evidence that stands behind these findings and conclusions; not only the stunning, obviously "artificial Phobos" now seen in the Mars Express close-ups (above) -- but the still-to-be-discussed results of two other key scientific experiments, carried out by Mars Express during these same fly-bys:
The "Phobos tracking" gravity/mass interior distribution experiment ... and the "MARSIS interior of Phobos" imaging radar experiment.
Spacecraft are usually monitored (tracked ...) by means of their broadcast radio transmissions; if the carrier frequency of the on-board radio system on the spacecraft is observed to vary ... as it is received by the ground stations here on Earth ... the major reason is usually a change (detected via a radio phenomenon called "the Doppler Shift") in the spacecraft orbit.
This orbit-change can be pre-planned -- the result of an on-board commanded thruster firing -- or (in the case of the close-in Mars Express Phobos observations), due to the slight gravitational field of the ~15-mile-wide moonlet itself being detected -- actually altering (very, very slightly ...) the expected (predicted) orbital trajectory of Mars Express around Mars ... during those super-close Phobos passes.
