Here is a wiki on Losif Samuilovich Shklovsky a Soviet astronomer and astrophysicist!
"In 1959 Shklovsky examined the orbital motion of Mars's inner satellite Phobos. He concluded that its orbit was decaying, and noted that if this decay was attributed to friction with the Martian atmosphere, then the satellite must have an exceptionally low density. In this context he voiced a suggestion that Phobos might be hollow, and possibly of artificial origin".
And I say it must be. It all ties in if there is a civilization living underground, and it has to be they are ! The martians don't want their planet to be battered. That fake asteroid can slow and speed up and has been detected as doing so. It is there to protect the martians from being bombarded with meteors and asteroids.
When you look at it is truly seems obvious it is not a captured regular nature made moon. Just look at the way it is indented, too round and metallic in and around the craters The grooves through out the moon are another obvious indication it is martian made and designed for protecting them when needed!
Also note the giant dent at the end, regular dirt type moons would never have that type of dent. Again, too rounded and can't be a regular nature made moon. If it was it would of crumbled because the indentation is too deep in it's curvature.
There are so many hints that there is current civilization on (under) mars it is not funny. And of course Photos's unnatural manufactured look is another hint that there is a current civilization on (under) mars!
It also goes around too low in it's orbit to be a natural moon! And the list continues to grow and grow that there IS a current civilization there!
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
