The descent stations of the Hayabusa 2 mission successfully landed on the surface of the asteroid 1999 JU3
The photo received by the rover 1B on September 21 this year. The picture was taken immediately after the module was separated from the station.
On Habr several times wrote about the Japanese mission to study asteroids "Hayabusa 2". The purpose of this mission is a survey of a specific asteroid, 1999 JU? which was opened on May 1? 199? as part of the LINEAR project, staff of the Socorro Observatory. To implement the mission, a probe was developed, which was created by the specialists of the Japan Aerospace Exploration Agency (JAXA).
As you can already understand by the name of the mission, there was also the first one. In the framework of the previous project, the first Hayabusa apparatus was able to reach the Itokawa asteroid in 2005. The new asteroid is twice the size of Itokawa, its diameter is ??? km. In July this year, "Habyusa-2" reached the final point of his journey. Well, the other day on the surface of the asteroid landed descent vehicles.
Descent vehicles MINERVA-II1 landed and are in normal mode. They move along the surface of the asteroid in jumps, and with them, we should expect, the representatives of the project team jumped for joy. Is it a joke - to develop a complex system designed to study an object that is extremely far from the Earth, and to achieve success in this endeavor, with both the descent of the device retaining its efficiency.
The photo received by rover 1A on September 21. It is also done immediately after separation from the station. The picture was taken during the rotation of the rover, so it came out blurry
Both vehicles were the first in the history of space exploration by rovers that hit the surface of the astroid. Modules, Rover-1A and 1B, are hexagonal, their size is small - only 18 centimeters across. The height of each - seven centimeters, weight - 1.1 kg. The main task of the rovers is to create stereo images of the asteroid soil. They are moved by means of a hopping mechanism. In addition to photographs, the modules are capable of solving other tasks, as they are equipped with optical sensors, an accelerometer, a gyroscope and thermometers.
This picture was taken by rover 1A on September 22. It was made in a jump, so it also turned out somewhat blurry. Nevertheless, it is quite possible to see the features of the surface of the asteroid, which means that scientists can already draw some conclusions about the nature of this object
Why study asteroids?
Many objects of this type are of the same age as the solar system. And they seem to have frozen in development, in contrast to the planets. And this means that studying asteroids can understand what the solar system was like at the very beginning of its existence, and also to study the material from which the planets and satellites were formed.
Ultimately, this can help to clarify how life has appeared in our system.
The asteroid to which the descent modules landed, moves along the solar system along a very elongated orbit. Thanks to her probe can easily return to Earth after the completion of the main mission. In addition, it belongs to the type of the oldest in the solar system of C-class asteroids. Its representatives are characterized by an increased content of carbon and hydrated rocks. The capsule with the substance of the asteroid will land on the Earth in December 2020.
