Phobos - mysterious Mars satellite has unknown origin?

Many people had discussion about it. It is time to discover at least approximate truth about this Mars satellite. Mars is certainly one of the most interesting planets in our system. He inspired the imagination of many people, and it is still unexplored place full of secrets. Is really possible that the key of his mystery lies in his moon Phobos?

In the history of space exploration, Phobos has inspired many scientists with assumptions. His unusual way of moving around the Mars and other features make it very special, and one of the explanations offered by scientists is that it is hollow.
That theory put forward Russian astrophysicist Josif Sklovski, but theorists have denied his claim. However, later it was determined that perhaps his theory was partly right, because it seems that about 25 to 35 percent of the interior of Phobos is really hollow.
Despite the efforts of scientists to investigate the mysterious moon, so far every attempt failed, and each time under suspicious circumstances. Therefore, the louder are people who claim that Phobos is not a natural satellite of Mars. They say that it is the station of alien forces that want to remain undetected.
This theory was inspired by the case from Russians. They probe launched in the year 1989. supposed to land on Phobos. After an unsuccessful landing and after viewing of images that the probe recorded, there was aircraft of unknown origin, which was seen in the moment before end of all contacts with probe .
Unfortunately, until today there was not any successful missions to Phobos, so there is no firm evidence to confirm any of the theories that are circulating about this mysterious moon.
