|New Theory for Mars' Moons|
A new theory about how Phobos and Deimos came about suggests that they are just the remnants of one larger moon. No one has yet been able to explain their orbits. Fred Singer, by performing complex orbital calculations, has said that a large moon in close proximity would have broken up due to gravitational forces. The chunks left would cling together into larger piles. The smallest remain as Phobos and Deimos. The rest would have crashed into Mars. Singer also says, that surface and deep soil samples are needed to see if the moons have the same composition, a fundamental prediction of his hypothesis.
