摘要

隼鸟2号宇宙飞船于2020年12月从小行星（162173）龙宫带回了样本。在这里，我们回顾了隼鸟2号任务的主要特征，特别关注样本收集和返回。在描述了材料是如何收集和随后的整理之后，我们概述了迄今为止任务的一些主要发现，包括有机材料的性质以及龙宫材料所经历的水蚀变的年龄、持续时间、程度和温度。我们讨论了这些观测对早期太阳系物质组成和它们所经历的过程的影响。最后，我们在即将进行的抽样返回任务的背景下考虑这些结果，以及从中可以学到什么。

Overview of the findings for samples returned from Ryugu and implications for early Solar System processes

The Hayabusa2 spacecraft brought samples to Earth from asteroid (162173) Ryugu in December 2020. Here we review the main characteristics of the Hayabusa2 mission, with a particular focus on sample collection and return. After describing how the material was collected and subsequently curated, we outline some of the major findings from the mission so far, including the nature of the organic materials and the age, duration, extent and temperature of the aqueous alteration experienced by the Ryugu materials. We discuss the implications of these observations for the composition of early Solar System materials and the processes that they have experienced. Finally, we consider the results in the context of forthcoming sample return missions and what may be learnt from them.

期刊介绍： Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
