Japan's space agency will attempt to land a robotic unmanned landing craft on the surface of a 300-million-kilometer asteroid next month.
The spacecraft Hayabusa-2 is currently orbiting Earth The diamond-shaped asteroid Ryugu, which it reached in June after a three-and-a-half-year journey.
On September 21, the spaceship will deploy the first of two lander asteroids themselves where they will collect and collect samples to conduct experiments. A second lander will be launched on 3 October.
Later in the mission, the spacecraft itself will land on the asteroid after it has blown a small crater of explosives so that samples can be collected below the surface of the object that did not exist
According to Japan Aerospace Exploration Agency (JAXA) will, if successful, be the "world's first sample return mission to a C-type asteroid".
Japanese scientists are currently running NASA's historic achievement, with the US State Department's own sampling mission, which will return to Earth in 2023. Hayabusa-2 is due to return in 2020.
Under its desolate surface, it is believed that asteroids contain a great treasure trove of information about the formation of the solar system billions of years ago.
"By exploring a C-type asteroid rich in water and organic materials, we will clarify the interactions between buildings. The Earth and the evolution of its oceans and their lives are evolving, developing the science of the solar system ", says JAXA.
C-type asteroids, which are mostly carbon, are the most common asteroid species, with more than 75 percent of them currently being discovered. The other two major types of asteroids, according to NASA, are the metallic S and M types.
Despite years of planning, Ryugu's diamond form surprised the team as the mission approached the asteroid.
"From afar Ryugu first appeared round, then gradually became a square before adopting a beautiful shape that was similar to fluorite ̵
"This form of Ryugu is scientifically surprising, and also poses some technical challenges," it said about difficulties, including landing, on the unusually shaped asteroid.
That said, the team has already achieved a mighty achievement by reaching the 900-meter-wide rock at all – something that was described as equivalent to hitting a 6-centimeter target at 20,000 kilometers (12,400 miles).
"In other words, reaching Ryugu is the same as a 6-centimeter target in Brazil from Japan," the agency said.
