Early in the morning, the Japanese spacecraft Hayabusa2 blew up an explosive device over a small asteroid. The goal was to create a fresh crater that would later be studied by a spacecraft.

The researchers observed from the mission management in Sagamihari, Japan, and politely laughed when Khayabusa2 released an experiment, known as the Small Hand-held Drummer. The device consisted of a copper disk packed with high-temperature HMX. As soon as the parent ship safely came out of the fire line, the drummer probably broke up, releasing the disc in the direction of the asteroid. The camera, released by Hayabusa2 appeared to be similar to the moment of impact which sent the ejection flux into space.

"He passed flawlessly," says Gerold Connolly Jr., a geologist at Rowne University. in New Jersey and co-investigator Hayabusa2.

and orbits between Earth and Mars. Researchers believe that Ryu can be similar to the early cosmic rocks that have been combined to make planets, including the Earth.

"These special asteroids are the precursors of what the Earth was made of," says Connolly. Ryugu is rich in carbon, and minerals on its surface contain water and so-called prebiotic compounds that could begin life on this planet.

"Ryugu is a time capsule," Connolly says. used to fire towards the asteroid. This video shows tests here on the ground.

This is not the first Hayabusa2 attack. In February, the spacecraft physically touched Ryu and released a small pellet on its surface. The dust raised by this discovery was collected and, in the end, will give researchers detailed information on the make-up of the asteroid.

But in order to really understand Ryu, the researchers also want to know that there, and so they created a crater of the night. A few weeks after the dust settled, a small spacecraft will look at the place of the explosion to see what lies below. He can land again to collect underground samples

The spacecraft is scheduled to leave Ryu at the end of this year, to transfer their samples back to scientists on Earth. Upon return, he throws a pod containing dust from Ryugu, which is expected to land in Australia
