The "bombing" by the Hiabusa-2 probe on the surface of the "Ryugo" surface caused the development of a large hole 10 meters in diameter, where the probe would have to land and collect soil samples to bring it back to Earth.
On April 4, the probe was separated from a platoon that acted like a cannon, and when it approached the surface of the asteroid "Ryugo", the explosion exploded and a copper capsule was fired on the asteroid.
This operation was intended to create a hole in the surface of the asteroid, suitable for landing the probe in May 2019, to collect soil samples under the crust, did not contact the outer space and was not exposed to the impact of the solar wind. According to the scientists, these samples will be very close to the materials from which the solar system originated.
The images obtained by the probe confirmed the development of a hole about 10 meters in diameter. According to experts, they expected a hole of this size only if the asteroid's soil was too loose. But the surface of the asteroid is solid and rocky, so experts have reexamined the probe's landing, because such an unstable rock would create a hole no more than ten feet in diameter.
"The surface is covered with rocks, but a large hole has appeared," said Masahiko Arkawa, one of the project's supervisors. "This could mean an unknown mechanism or a specificity for asteroid material."
