NASA called the dates of the destruction of Phobos Mars
Scientists have named the deadlines for Mars to destroy one of its two satellites, Phobos. About this, as reported on the NASA website, planetologists 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, after about 30–50 million years, the gravitational pull of Mars will lead to the destruction of Phobos into smaller fragments, some of which fall to the surface of the planet.
Planetologists came to such conclusions by analyzing the spread of cracks (grooves) in the vicinity of the Stickney crater (on the right-hand side of the CDPV). They, as the researchers found out, were formed not because of the collision of Phobos with an asteroid, but as a result of the occurrence of internal stresses in the celestial body.
The appearance of deformations scientists associate with two main factors. First, Phobos (with a radius of 11.1 kilometers) is located at a distance of six thousand kilometers from the surface of Mars.This makes him the closest satellite to his planet in the solar system.
According to the calculations of scientists, every hundred years, the satellite becomes closer two meters to its planet. Secondly, Phobos has inside a multitude of cavities, which make up about a quarter of its total volume, whereas outside the celestial body is covered with a hundred-meter layer of regolith.
For the first time cracks on the satellite of Mars discovered the station Viking. Similar structures are observed on Triton - the satellite of Neptune. According to scientists, over time, Triton, as well as Phobos, will break the gravitational pull of its planet.
