Many beautiful solar system samples ever
Experts from the OU carried out oxygen isotope analysis on samples from Ryugu. They used information that was a crucial component in establishing the links between the returned asteroid materials and the existing meteorite record.
Based upon spacecraft information, it was formerly thought that the Ryugu material had experienced heats. Many of the water it included was believed to have actually been driven off because of this. This theory was found to be inaccurate.

In reality, the material consists of a lot of water and raw material. OU specialists were able to validate that the Ryugu samples are very comparable to meteorites of the CI (Ivuna-type) chondrite group. These are thought about the most important single meteorite group due to the fact that they have a structure that matches that of our Solar System. They were likewise able to show that CI chondrites have been contaminated by their interaction with the terrestrial environment.
Due to the fact that the Ryugu samples were collected and gone back to Earth in ultra-clean conditions, they are the most beautiful, primitive Solar System samples that we have.
More precious than gold dust
The OU team was consisted of Richard Greenwood, Ross Findlay, Ian Franchi, and James Malley.
Richard Greenwood is a Research Fellow at the OU and supported the study through isotope analysis. Dr. Greenwood explained the value of the research study:
” When Asteroid Ryugu was surveyed in space by the Haybusa2 spacecraft it looked as though the arise from the mission may be a bit disappointing. It seemed that products from which the asteroid was made up had been heated to a heat and much of the water kept in them had actually been lost to space.
” However, while working as part of the Japanese Kochi Team, OU scientists had the ability to show that the Ryugu samples were closely comparable to the important and unheated CI (Ivuna-type) chondrites. These are materials that have a structure that carefully matches that of the Solar System itself, including the Sun. For understanding the chemistry of the Solar System it ends up that the Ryugu products are more valuable gold dust.”
Despite the product from Ryugu being aqueous (of or containing water), low temperatures indicate the main relationships between its minerals and the organic part have actually been protected. Isotopic proof (hydrogen and nitrogen) shows that the fine-grained minerals and organics seen in the Ryugu particles formed in the external Solar System.
Because of this study, professionals have been able to conclude that materials in primitive asteroids may have functioned as cradles for natural molecules. This would have assisted to maintain them and so offers a prospective mechanism for the paired delivery of water and organics to the early Earth.

The Kochi Team2 has carried out an in-depth research study of eight particles returned to Earth from asteroid Ryugu by the JAXA3 spacecraft Hayabusa2. Based on spacecraft data, it was formerly believed that the Ryugu material had actually experienced high temperature levels. OU experts were able to confirm that the Ryugu samples are very comparable to meteorites of the CI (Ivuna-type) chondrite group.” However, while working as part of the Japanese Kochi Team, OU scientists were able to show that the Ryugu samples were carefully similar to the unheated and essential CI (Ivuna-type) chondrites. For understanding the chemistry of the Solar System it turns out that the Ryugu materials are more precious gold dust.”

Asteroids from the outer Solar System might have brought the structure blocks of life to Earth.
New research has revealed essential new clues regarding how the inner Solar System, consisting of Earth, obtained its water and organic-rich parts– the necessary foundation for all life.
The Kochi Team2 has carried out a detailed research study of 8 particles returned to Earth from asteroid Ryugu by the JAXA3 spacecraft Hayabusa2. They are supported by scientists at The Open University (OU) and the University of California, Los Angeles (UCLA), USA and led by Motoo Ito of JAMSTEC. It was released on August 15, 2022, in Nature Astronomy.
