The Japanese professor announced that signs of water and organic matter were found in the “Ryugu” sample

Nakamaru’s team is one of eight teams in Japan that have received or will receive samples of Ryugu Rock and sand for analysis. These samples were brought back to Earth in a capsule released by the Japanese Hayabusa-2 asteroid probe in December last year.

On June 2, researchers at Okayama University began analyzing these samples earlier than other teams.

Nakamaru said that his team measured the amount of hydrogen, carbon and nitrogen atoms in the sample and converted the data into the amount of water and organic matter that could be formed.

The research team will analyze these samples for a year to reveal the source of water on the earth. They will also try to determine what kind of organic matter exists on the asteroid.

Tachibana Shogo, a professor at the University of Tokyo, is the coordinator of this study. He said that he hopes that the analysis of these samples can provide various evidences, and then provide clues to the solar system, the origin of life on Earth, and how the oceans were formed. JAXA Hayabusa 2 project manager Tsuda Yuichi said that the research team is finally ready to conduct advanced analysis and look forward to new scientific achievements.
