The latest research revealed the formation of Phobos crater groove mystery mystery (video)

The latest research revealed the formation of a mysterious crater Phobos mystery groove as shown above left is the origin of Phobos collision process will form a unique geological structure on the surface (above right). The tidal gravity model before left in the formation of the crater chain, right below is the origin of the collision process simulation. Tencent space news according to the British Daily Mail reported that the satellite of Mars Phobos is one of the cross, the distribution of surface craters and grooves, but before scientists don’t know this peculiar surface structure is formed. At present, a new study shows that Phobos surface craters may be formed in the collision process of the material before injection and after injection of material into orbit for a period of time, they will fall into the Phobos surface to form a larger crater. From the surface of Mars Phobos only thousands of kilometers, is now gradually close to the surface of mars. It is close to the surface of Mars, means the satellite by tidal forces influence from Mars gravity, thus forming a larger surface protrusions and Phobos stripe structure. However, many craters and grooves do not at the expected direction, which is formed by the force of the tide, which implies that there may be another origin. Before the United States of California University of Santa Cruz Department of earth and planetary science researchers simulated collision trajectory material Phobos jet. They found that Phobos crater chain is "the origin of collision process, origin of" collision "refers to the ejected material escape Mars gravity, orbiting Mars for a period of time, again after the collision of phobos. Along with this process is repeated, origin of "collision" will form a series of crater on Phobos surface. Study leader Eric – Aisifo (Erik Asphaug) pointed out that repeated collision type helps the out of the ordinary for the first time announced the celestial body collision crater formation, the formation of surface features a unique way to detect planets. Although the origin of "collision" is likely to lead to the formation of some crater chain, large tidal gravity on Phobos, will have a great influence on surface structure. At present, the latest research report published in the recently published "nature" magazine, will help scientists to better understand the geological history of the solar system satellites.
