Spacecraft Hayabusa2 makes an artificial crater of the asteroid Ryugu



Yomiuri Shimbun The world's first cosmic explorer, Hayabusa2, managed to create a crater on the surface of the asyroid Ryugu on April 5, Japan's Aerospace Research Agency (JAXA) announced.

Now JAXA will decide whether to get the researcher to touch the crater to get a sample.

At an altitude of 1.7 kilometers, Hayabusa2 took a picture Thursday on the surface of Ryugu, where the researcher discarded a lump of honey weighing about 2 kilograms.

Comparing this photo with one of the same areas made before the strike confirmed the appearance of a crater 10 meters in diameter. "This is the biggest crater within our expectations," said University Professor Kobe Masahiko Arakawa, who is in charge of scientific analysis. Around the crater were seen accumulated pieces of broken rocks that rose when the lump struck. The crater is created from 10 to 20 meters from the object, indicating that Hayabusa2 has been able to throw out the copper lump to hit Ryugu with high precision.

Yuichi Zuda, head of the Hayabusa2 JAXA project, said at a press conference in Tokyo on Thursday: "We managed to leave a mark on Ryugu. I'm so happy I could jump. There are dangerous uneven zones, so we'll solve it [whether to make Hayabusa2 touch down on Ryugu] within one to two months. "

On the surface of the crater are exposed rocks that were present during the initial state of the solar system about 4.6 billion years ago and there is the possibility that water and organic materials remain in them. Their study is expected to explain the history of the solar system and the asteroids.
