Scientists have long believed that the Martian moon Phobos could be porous and filled with vast caverns.
In an effort to shed new light on the nature of Phobos the Mars Express spacecraft flew by it on Wednesday so that scientists could examine the way in which the moon 'tugged' on it as it went past.
Back in the 1950s and 1960s, there was some speculation that Mars moon Phobos could possibly be hollow due to the its unusual orbital characteristics. While scientists now agree that the moon is very likely not hollow, vast caverns may exist within the moon, and it might be a porous body instead of solid.
