Analysis of asteroid samples returned by Hayabusa 2 and Osiris-REx

今年，备受期待的隼鸟2号航天器将携带小行星Ryugu的样本返回Woomera。这只是历史上第五次地外样本返回使命。该研究团队已受邀参加将于2021年初在日本举行的初步审查。 研究人员开发了独特的分析技能，可以以前所未有的精度测量少量岩石的氧同位素组成。该项目旨在研究一套碳质陨石，这似乎是最适合Ryugu的，因此将提供范例数据来了解Ryugu的起源，并将其置于太阳系材料的背景下。

This year sees the highly anticipated return of the Hayabusa2 spacecraft to Woomera carrying samples of the asteroid Ryugu. This is only the fifth extraterrestrial sample return mission in history. The research team has been invited to participate in the preliminary examination which will take place in Japan in early 2021. The investigators have developed unique analytical skills that allow measurement of small amounts of rock for oxygen isotope compositions at unprecedented precision. This project aims to characterise a suite of carbonaceous chondrites, which appear to be the best match to Ryugu, and therefore will provide the exemplar data to understand the provenance of Ryugu, and place it in the context of solar system materials.
