Phobos

Phobos, the larger of the two moons of Mars, is in the process of a catastrophic structural failure. Scientists originally believed that the presence of grooves on Phobos’ surface were a product of a past impact that created the Stickney crater, but these findings were abandoned when it was discovered that the grooves radiated away from a different focal point. What do these grooves mean for Phobos? According to NASA, “The interior of Phobos could be a rubble pile, barely holding together, surrounded by a layer of powdery regolith about 330 feet (100 meters) thick.” This means that tidal forces will eventually (10 to 20 million years from now) tear the moon apart and its debris will form a ring, similar to Saturn, around the planet.
