Behind primary matter. Rovers have sat down on an asteroid


Hayabusa-2 has lowered devices which will collect on Ryugu and will return to Earth of a particle of a protosolar fog. The Japanese probe Hayabusa-2 has made successful disembarkation of MINERVA-landers Ⅱ 1 on a surface of a near-earth asteroid of Ryugu from Apollo's groups. The purpose of a mission is delivery to Earth of the first absolutely "clean" tests of primary matter of Solar system. Корреспондент.net rasskazyat details. As пояивлась the Solar system and life As has arisen Solar system and as in it there was life - these two questions already long time interest scientists. Observations of other star systems have expanded knowledge of development of planetary systems. Iissledovatelya "chemistry" - structure of planets and their atmospheres and as it depends on the place of formation of the planet and on age and structure of a star also interests. Have groped life. New opening of Curiosity on Mars in case of Solar system understanding of chemical processes can help to answer a question as our Earth and other planets was formed and from where on her life has arisen. To find substance which remained after formation of planets difficult, especially in original state посколько too much time has passed. However particles of a protosolar fog can be met on "primitive" bodies - the small asteroids or comets formed on suburbs of Solar system. The element structure of such bodies is close to structure of the Sun, and the age is estimated more than in 4,5 billion years that almost corresponds to age of our planetary system. Onboard devices can't open completely all secrets of the chemical composition of these objects. To deliver absolutely clean tests of primary matter of Solar system to Earth to investigate them in laboratories, - it is the purpose of Hayabusa-2. The jumping rovers the Automatic interplanetary station Hayabusa-2 has been started on December 3, 2014 from the spaceport of Tanegashima in Japan. On December 3, 2015 the probe has made gravitational maneuver near Earth, having passed at distance of 3100 kilometers from it, and, having received additional acceleration, has gone to Ryugu's asteroid. The Japanese device has achieved the objectives at the beginning of June and has begun the long procedure of braking and rapprochement with an asteroid. On June 27 the device came to a stable 20-kilometer orbit around it. There the station has carried out mapping of a surface of an asteroid therefore scientists could construct two three-dimensional models of rotation of an asteroid of team of a mission. Liquid water on Mars. As have made discovery at the end of July the device approached Ryugu's surface to six kilometers, and at the beginning of August has decreased to the minimum height in 851 meters from Ryugu's surface within the experiment on studying of gravitational field of an asteroid and shooting of his surface at a short distance. Also the team of scientists has studied amount of rocky breeds to estimate reality of collision of an asteroid with other large object in the past. On September 20 decrease in Hayabusa-2 has begun, and disembarkation of MINERVA-Ⅱ has happened today on September 21 at the height of several meters. Before at the height of 500 ме
