A research team announced that as a result of a detailed examination of a container containing sand collected on an asteroid by the Japanese probe "Hayabusa 2", a very small amount of gas attached to the surface of the sand was detected.
The research team says that the high technological capabilities of Japan brought back solids, liquids, and even gases from the asteroid.
The presentation was made by a research team led by Associate Professor Takashi Okazaki of Kyushu University.
In the analysis of the sand of the asteroid "Ryugu" collected by "Hayabusa 2", several results such as the discovery of a trace amount of "carbonated water" have been announced.
The samples collected from the asteroid were brought back to Earth in a highly airtight cylindrical container, but as a result of a detailed examination of the container by a research team from Kyushu University and others, it was found that there was very little dust adhering to the surface of the asteroid, such as sand. announced that it detected a small amount of gas.
The gases are noble gases such as helium and neon, which are almost non-existent in the Earth's atmosphere.
The research team has succeeded in bringing back solids, liquids, and even gases from an asteroid about 300 million kilometers away from Earth in an exploration by "Hayabusa 2". .
Associate Professor Okazaki says, ``The container was highly sealed, and the gas was not lost. .
