The second unmanned asteroid probe of Japan "Hayabusa 2" is confirmed with the image of an artificial crater on the surface of the asteroid "Ryuu", which is the subject of the research. This is the first time human beings have made craters (craters) of artificial impulses on the surface of the asteroid.

On May 25, the Japanese Aviation Research Agency (JAXA) announced that "I was again approaching the limb surface to confirm the result of a metal bullet collision that fired on the surface of the island of Ruuga on the 5th." I confirmed it with the naked eye. "For this purpose, Hayabusa 2 approached 1.7 km above Liu Gu and photographed the surface.

On May 5, Hayabusa 2 hit the surface of Riegu with a metal bullet in the air in order to collect the underground soil exposed during the process of forming an artificial crater. However, at that time, the only hit was confirmed, and it was not confirmed whether craters were formed on the surface.

On May 5, Hayabusa 2 approached 500 meters above the surface of Ryugu and set aside a 2.5kg copper-clamp device called "SCI" ​​and a camera called "DCAM3". Then, using the explosive force, SCI was shot as a bullet on the surface of Ryuge and encountered the formation of a crater. Hayabusa 2 has stayed away from SCI in order to avoid damage from dust that would cause a collision. Hayabusa 2 waited until the dust caused by the collision did not calm down.

Hayabusa 2 will return to Liuqi later this year and will collect the underground soil "excavated" from the newly formed crater and store it in a solid capsule weighing 16kg in weight called "SCR" and will begin to return. Depending on the condition, one surface can be landed on the surface once more and the second sample of the surface is taken. Start the ion engine and point it to Earth, then re-enter the capsule to complete the mission.
