U.S. astronaut, Buzz Aldrin, the second man to walk on the Moon,
alluded to a monolith detected on Mars' moon Phobos. Speaking on

structure on this little potato shaped object that goes around
Mars once every seven hours. 'When people find out about that

unmanned mission to Phobos known as PRIME (Phobos Reconnaissance
and International Mars Exploration). Phobos is a vastly
promising location for future exploration. The moon itself has

be hollow. More aggressive speculation suggests that Phobos may
in fact be a derelict spacecraft of the "generation ark" variety
described by science writers such as Isaac Asimov. Unexplained
