Recently, researchers at the University of California in Santa Cruz decided to test another hypothesis: "What if the fragments are the cause of a series of small" holes "on Phobos ' surface? not by Mars ". The illustration above clearly describes the sequence of events and scientists have noted the origin of the moons on Mars. ( The trajectory illustration is drawn in the wrong ratio )

Michael Nayak and Erik Asphaug at the University of California and Santa Cruz conducted computer simulations to verify hypotheses about the origin of Phobos tracks. The simulation performed on the computer creates a model that describes the basics or initial impact that causes large indents and blows dirt into space. Following are the second and subsequent impacts that moon debris will return to Phobos' surface. Model a series of dents in the left-hand image that is similar to the predicted model ( right ).
