Scientists dubbed the timing of the destruction of Mars 2 of one of our own satellites - Phobos. About it, as described on the website of NASA, planetary scientists told during the 47th annual meeting of the Planetary division of the American astronomical society in Maryland.
According to the model proposed by the authors, approximately 30-50 million years the gravitational attraction of Mars will lead to the destruction of Phobos into smaller fragments, some of which will crash on the planet's surface.
So planetary scientists have come, having analysed the propagation of cracks (grooves) in the vicinity of the crater of San MATEO. They, as researchers learned, is not the result of the collision of Phobos with an asteroid, and eventually the origin of internal stresses in the heavenly bodies.
The advent of the destruction of the scientists associated with 2 main factors. First of all, Phobos (with a radius of 11.1 kilometers) is located at a distance of 6 thousand km from the surface of Mars. This makes it the closest planet to its own satellite in the Solar system.
According to the calculations of scientists, every 100 years the satellite becomes closer to 2 m. to their own planet. Also, Phobos has a lot of cavities, which make up around a quarter from its joint volume, however, the outside heavenly body covered with a hundred-meter layer of regolith.
First cracks in the Martian satellite has found a station Viking. Similar structures exist on Triton, a satellite of Neptune. Taking into account the opinion of scientific workers, over time, Triton also and Phobos, will break the gravitational pull of our own planet.
