Pyramid to Ceres found by NASA - VIDEO PDF Print E-mail

NASA prepared the original video tour of the main attractions on the surface of Ceres - Okkator crater with mysterious white spots, and the mountain-pyramid, using images and data on the topography of the dwarf planet collected probe Dawn. "This mountain is the highest peak on the surface of Ceres, from among those that we have found to date. Surprisingly, this pyramid and the history of its appearance, apparently not connected with the birth of a crater. Why it exists in it godforsaken place? We do not know yet, but we hope that the next convergence with Ceres will bring us closer to the answer ", - said Paul Schenk (Paul Schenk) from the Institute of the Moon and planets (LPI) in Houston. Schenk and his colleagues used the images of the surface and the surface of the topographic map of Ceres, transmitted to Earth last week, to produce a three-dimensional model of the dwarf planet and training videorolika- "tours" on the surface, that allows network users to first look at the three-dimensional shape of Ceres attractions. Interestingly, in the preparation of this map, scientists have uncovered a number of new features white spots in the crater Okkator, who once again made their nature even more incomprehensible. Prior to this discovery planetary inclined toward what they are deposits of water ice, but measured Schenk and his colleagues albedo - reflecting ability - white spots was significantly lower than that of ice. Another said scientific team Dawn, Head of Mission Christopher Russell, now scientists measure the albedo of different salts in the world, trying to find or choose a value that would be consistent with those that are characteristic spots on Ceres. As the planetary, the mystery of "pyramid" and the white spots can be partially open in the middle of August, when the Dawn will complete the next cycle and lowering the orbit to reduce the distance with Ceres from 4.5 to 1.5 thoUSAnd kilometers. 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.
