Scientists hope to uncover the secret of the particle formation of the solar system. UAV Hayabusa, which means falcon in Japanese, damaged when entering the Earth's atmosphere in June, but had dropped the box containing the sample container after landing on the asteroid Itokawa, which approached the Earth in 2005. Japan Aerospace Exploration Agency (JAXA) said particles have the potential to give clues on how the solar system formed 4.6 billion years ago. Asteroids are believed to retain its pure form in a long time, unlike the Earth's surface, which influenced changes in the atmosphere, water and volcanic activity. 'Many things are not known to man, like, how the Moon formed,' said a spokesman for JAXA. 'The study, not only with these particles, but with other findings, can give us instructions on how the solar system and planets formed, "he said.
Part of that example can be given in the next year to researchers around the world for further testing. Most of the particles are smaller than one per 100 millimeters and elements including minerals, such as olivine, pyroxene and plagioclases. Researchers also hope that these findings give an answer from the dangers of asteroid collision with Earth.
