The Japanese scientist managed to create what they call the first artificial asteroid crater, a step forward to shed light on how the solar system evolved, the Asian Space Agency announced on Thursday.
The announcement was announced after the Hayabusa2 probe launched an explosive device of the Rugu asteroid earlier this month to create a crater on the surface and to raise material in order to discover more about the origin of life on Earth.
Yuichi Tsuda, head of the Hayabusa2 project at the Japan Aviation Research Agency (Jaxa), told reporters that the creation of the crater was confirmed by images captured by an investigation located at 1,700 meters from the surface of the asteroid.
"The creation of an artificial impact crater and detailed monitoring is then the world's first," said Tsuda.
"It's a great success," he added.
The NASA Depp Impact investigation has managed to create an artificial comet crater in 2005, but only for observation purposes.
Masahiko Arakawa, a professor at the Kobe University who participates in the project, said it was "the best day of his life".
"We can see a big hole much clearer than expected," he said, adding that the images showed a crater with a diameter of 10 meters.
Ryugu is believed to have large amounts of organic matter and water about 4,600 million years ago when the solar system was formed.
In February Hayabusa2 landed briefly on the Rugu asteroid and fired it, which allowed him to collect dust samples before returning to his original position.
The adventure of Hayabusa2, at a price of about 30,000 million yen ($ 270 million), began on December 3, 2014, when the investigation began a long journey of 3,200 million kilometers to reach Ryugu, an average distance of 340 million kilometers Earth, because it's impossible to go straight.
He plans to return to Earth in 2020.
