对隼鸟2号和奥西里斯-雷克斯返回的小行星样本进行分析。今年，备受期待的隼鸟2号宇宙飞船将带着小行星龙宫的样本返回乌默拉。这是历史上第五次地外样本返回任务。研究小组已被邀请参加将于2021年初在日本进行的初步审查。研究人员已经开发出独特的分析技术，可以以前所未有的精度测量少量岩石的氧同位素组成。该项目旨在描述一组碳质球粒陨石的特征，这些球粒陨石似乎与Ryugu最匹配，因此将提供范例数据来了解Ryugu的来源，并将其置于太阳系物质的背景下

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