Abstract
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.
