The first detailed images: Japanese probe is close to the asteroid Ryugu

The first detailed images: Japanese probe is close to the asteroid Ryugu The Japanese in 2014 she launched into near space to its most modern probe"Hayabusa-2", and for the three-year period of the flight, finally it has reached the intended point and got to the asteroid Ryugu, now between the probe and the chip rocks about 20 km, according to Japanese experts from the Agency (JAXA). The probe successfully worked for three years, because it was on the way for such a period of its operation, all the electronics survived and here is a piece of silicon with a casing of sensors with a battery was at a distance of 32 billion km from the Earth near the asteroid ryu. The asteroid is not large by space standards, its diameter is only 900 meters. The probe will accompany the asteroid for about a couple of years. Soil samples from the surface of the asteroid will be taken automatically. The first attempt to take soil samples will be carried out in the autumn of 2018. The experience of similar missions in Japan is the Hayabusa mission in 2010, flew to the asteroid Itokawa and successfully took samples of the soil. The asteroid Rucu runs between Mars and Earth and if traces of water or organic matter are found in the soil, it will be a vivid confirmation of the hypothesis about the past of the Martian belt.
While the probe is still approaching, but in a few days it will be very close to the asteroid, which is almost a kilometer in diameter. There are already even the first pictures of the surface area that got into the lens of the photo camera of hayabus-2." The probe Ryugu is essentially a piece of untouched primary matter and which subsequently built the planet for a period of 4.5 billion years. The first picture came when the probe was at a distance of only 240 km from the astroid. The asteroid is clearly visible, although small details of the surface are difficult to see. There are both flat areas and impact craters on the surface. In the network there is already a movie from a set of pictures, which shows the asteroid itself in rotation. All these photos were taken at a distance of 700 km. Analysing images of the asteroid, scientists came to the conclusion that it is composed of different color segments. Everything in it is wrong, he is even moving in reverse orbit.
According to the plan on July 27, the probe should get to the surface of the asteroid as close as possible, at such a close distance the probe will accompany the asteroid within 6 months. During this time, you should get a complete map of the surface of the asteroid. Then scientists will choose where to plant the landing module Mascot (Mobile Asteroid Surface Scout) in order to get a picture of the composition of the soil. The landing probe will conduct a controlled explosion and examine the ground. Next, the selected soil will be taken on Board and delivered to the Ground.
When the experts will determine the place of landing, then will start the procedure, which should be delayed for all 16 hours, the probe smoothly suitable for removal of only 100 meters. Next landing probe in free fall will land on the surface.
Perhaps most scientists are interested in the question What is the soil, what is the substance on the surface of the asteroid What on its surface temperature. The asteroid appeared about 4.5 billion years ago and has not changed all this time, for this reason it is almost unique. When the soil collection is completed, and it will be somewhere in December 2020, the mission will go back home.
