A photo from open sources Comet 67P Chyuryumova-Gerasimenko formed relatively recently as a result of an eruption of unknown nature with Jupiter’s surface, so relic is unlikely to be found there substance of the solar system, Interfax-AVN reported on Tuesday Russian researcher of comet meteorites Evgeny Dmitriev. “Comet Chyuryumov-Gerasimenko does not meet European expectations scientists discover on it a relict substance left on a comet since the birth of our solar system, “said the researcher in connection with the planned landing of the Fila module on November 12 Rosetta spacecraft of the European Space Agency (ESA) to the surface of the nucleus of this comet. “Conducted for 30 years studies of tektites and pseudometeorites deposited on Earth (16 falls and five finds) showed that they are chemical and mineral composition, according to the mechanism of their destruction in the atmosphere and fragments fall too sharply from well-known meteorites, “he said. Pseudo-meteorites are called objects, a fact whose falls are undeniable, but their meteorite nature is not recognized. Basically it is glass, slag and pumice. “The result was made the conclusion that the studied objects are comet meteorites, moreover, the comets themselves from which they have fallen are not residues protoplanetary clouds and do not contain the oldest substance The solar system, as a product of an eruption (eruptive emissions) from celestial bodies located in systems planets – giants, “said E. Dmitriev. According to him, the substance comet meteorites are highly differentiated, have a complex composition, similar to the composition of the earth’s crust. In some meteorites having high alkali metal content, streamer glasses were detected – skeletal remains of primitive marine animals: sponges, radio displays, intestinal cavity. “All this is experimental confirms the classical eruptive hypothesis of the origin of comets, put forward in 1812 by Joseph Louis Lagrange, “he said. “Such a mechanism exists in nature, and it will be open soon,” – sure researcher. “Analysis of images of comet Chyuryumov-Gerasimenko, made by the Rosetta probe leaves no doubt – the core comet is a fragment of the crust of the stone body of the planet Jupiter, recently thrown out of its bowels by an eruptive process unknown nature, “- says Dmitry Dmitriev. Attempted landing Phil’s research robot on the comet nucleus will be executed for the first time in the world. The mass of the robot is about 100 kg. It is equipped with 10 scientific instruments with which it is planned to make a fence substance of the comet’s nucleus and explore its composition. Comet Chyuryumova-Gerasimenko was discovered in 1969 by two Soviet astronomers. The Rosetta probe was launched on March 2, 2004. IN August this year he approached the comet and is now in orbit around its core at a distance of over 500 million km from the Earth. November 12th the robot undocks from the probe at the moment when the distance between it and the nucleus of the comet will be 20 km. Confirmation of undocking will reach Earth in only 28 minutes. Landing will take place 7 hours later, at about 18:35 Moscow time. The total project cost is 1.3 billion euros.
