This NASA photo obtained on November 11, 2015 shows the long, shallow grooves lining the surface of Phobos are likely early signs of the structural failure that will ultimately destroy this moon of Mars. Orbiting a mere 3,700 miles (6,000 kilometers) above the surface of Mars, Phobos is closer to its planet than any other moon in the solar system. Mars gravity is drawing in Phobos, the larger of its two moons, by about 6.6 feet (2 meters) every hundred years. According to a study published in the British journal "Nature Geoscience" on November 23, 2015, scientists expect Phobos to be pulled apart in 20 to 40 millions years and its fragments should form a ring around the red planet.
