Space probe “Hayabusa-2” successfully landed landers MINERVA-Ⅱ1 on the surface of the asteroid Ryugu, both devices operate normally and transmit pictures, it said in a statement on the website of the mission.
“We received confirmation that both vehicles sat on the surface of the asteroid Ryuga. Both rover in good condition, they transmit photos and data. Analysis of these data confirmed that the modules are moving along the surface of the Ryuga, “the report said. Thus, MINERVA-Ⅱ1 became the first in the history of space exploration by rovers on the surface of an asteroid, noted in the Japanese space agency JAXA.
The Rover-1A and 1B modules are hexagonal in shape and 18 centimeters in diameter, seven centimeters high and weighing about 1.1 kilograms each. Rover-1A is equipped with four cameras, Rover-1B – three, they are designed to create stereo images of the Ryugu ground. Modules are able to move around the surface of the asteroid due to the hopping mechanism and are equipped with sensors for measuring soil temperature, optical sensors, accelerometer and gyroscope.
The Hayabusa-2 automatic station was launched into space in December 2014. Its purpose is to deliver soil samples from the asteroid 162173 Ryugu , which belongs to the class C asteroid . The device successfully arrived to the asteroid on June 27 and came out on a stable 20-kilometer orbit around it. In the next year and a half, the probe will probe the Ryuga from orbit, will descend onto its surfaceMASCOT module (Mobile Asteroid Surface Scout), on which a spectrometer, magnetometer, radiometer and camera are installed. It is assumed that when approaching the Ryuga, the device will fire on the surface of the SCI device (Small Carry-on Impactor), consisting of a copper shell and an explosive charge, thereby enabling researchers to study the composition of the upper layer of the asteroid soil. After taking a sample of soil from the surface of Rigu station will go back to Earth and drop the capsule with the substance of the asteroid in December 2020.
