Mysterious white spots on the surface of the dwarf planet Ceres, Dawn probe open immediately upon arrival it became even more mysterious - it turns out that their mothers gradually evaporates into space, creating a kind of atmosphere above them, the newspaper writes Space.com. "If you look at the spot at a certain angle, you will see something like a fog or haze, which appears and disappears in a strictly defined period of time. The bright spots in the Ceres likely to sublimate (turn from ice to vapor) under the action of the Sun's rays and the steam or leaking into space, or create a kind of atmosphere in this corner of the dwarf planet "- he told Space.com Christopher Russell (Christopher Russell), head of mission Dawn. According planetology existence of such a haze or "atmosphere" is by far the most convincing argument in favor of the white spots are deposits of ice, not deposits of mineral salts. The activity of these spots, as well as the relative youth and some other features of the surface of Ceres, explains Russell, suggest that the dwarf planet bowels are not completely lifeless, as previously thought. Russell and some other members of the research team Dawn even believe that under the surface of Ceres can exist in a liquid water ocean. Dawn science team hopes that the transition to a new orbit of the probe will help them verify these hypotheses and to reveal new secrets of the life of the dwarf planet. The American probe Dawn, launched by NASA in late September 2007, became the first spacecraft, which studied the one heavenly body - Vesta, one of the largest asteroids, descended from its orbit after a year and went to another - Ceres, the closest planet to Earth dwarf . Dawn has successfully reached its goal on March 6 of this year, 16 hours 36 minutes Moscow and began to study the surface and subsurface of Ceres, which will continue for about 16 months. He was the first "see" dwarf planet is so close. Learning both the largest protoplanets, scientists believe, will help them determine how the planets were formed in the "youngest" of the solar system. During the beginning of the third planned reduction of the orbit, June 30, the probe Dawn has experienced a failure and went into safe mode, where he stayed for almost three weeks. During this time, NASA engineers found that the problem was the improper operation of the system, which controls the position of one of the three ion engines of the probe, and decided it by going to another engine.
