The Ryugu asteroid, associated with the Japanese Hiabusa 2, has begun to reveal some of its secrets: researchers have detected minerals mixed with water on its surface, which could help to understand the contribution of asteroids to water and life.
Three studies were published this week in the journal "Science" of this distant astronomer discovered in 1999.
"This is the first data we have on a carbon asteroid," said astrologer Patrick Michel, head of the US Osiris-Rex mission. The results were also released this week in Nature.
"It's like discovering a new world and we feel like Christopher Columbus," said Michelle, director of research at France's National Center for Scientific Research, who is participating in the Hayabusa 2 mission.
"Minerals mixed with water are present everywhere," said AFP Kohi Kitazato, from Izu University in Fukushima.
"Carbonaceous asteroids are a potential source of water on Earth and we hope that our future studies and analyzes will provide new evidence of the origin of water on Earth," he said. .
Ryugu, located 340 million kilometers from Earth and 900 meters in diameter, is a very old asteroid, 100 million to a billion years old. The Japanese space agency Hayabusa 2 has been linked to this agency since June 2018.
"We do not know what it is in the basement because the heat is very low a few inches from the surface," said Patrick Michelle.
The astrophysicist reveals that Ryugo "contains less crystalline water than Pino, which suggests that Ryugu was exposed to a temperature slightly higher than that of Pino, who partially dried it".
– Parallels –
Astrophysicists were surprised by the similarities between asteroids, especially in terms of shape and mass, and the extent of rock dispersal at the surface.
Like Pino, Ryogo is a circular shape with a bulge at the equator. It revolves around itself for 7.7 hours and looks a bit like a "whirlpool", explains Patrick Michel.
It is twice as large as Pino and its density is low (1.2 grams per cubic centimeter) and has many pores.
It's like the dark Pino, which means that it can be rich in carbon and then in organic compounds. However, Hayabusa 2 must be brought back to the ground with samples to check the order.
"We hope to get organic materials to see if their specifications match those that gave life to life," said Michel.
The researchers were surprised to discover that the rocks were scattered all over the surface.
Ryugu is part of what is called the asteroid belt, "probably an agglomeration of small parts of a larger body that was destroyed by a collision," according to Patrick Michel, who points out " the importance of understanding the history of these astronomical objects ".
Hayabusa 2 is scheduled to conduct an experiment on April 5th to send a pumpkin to Ryogo's roof to create a slot for the purpose of taking samples.
It is the detail of the story of the asteroid Ryugo that begins to unveil the secret of today, we hope we were given by giving you the details and the complete information and by following any our news, you can subscribe to the alert system or to one of our different systems to provide you with all the news.
