钱德拉雅安-3 号探测器揭示月球岩浆海洋

与更常见的遥感相比，对行星表面的现场测量可以提供有关矿物组成和元素分布的更详细信息。最近，Santosh Vadawale 及其同事报告了印度 Chandrayaan-3 号任务的 Pragyan 漫游车所搭载的阿尔法粒子 X 射线分光仪（APXS）实验的早期结果，其中描述了 Chandrayaan-3 号着陆点的特征及其对月球历史和演变的启示。利用测量到的不同 X 射线的通量确定了单个元素，并得到了 Chandrayaan-1 和 Chandrayaan-2 轨道器进行的 X 射线荧光遥感观测的证实。作者能够确定 12 种主要和次要元素以及几种氧化物的丰度，并发现着陆点周围有铁质正长岩和镁质岩的混合，空间分布非常均匀。这些观测结果支持月球岩浆海洋模型的预测，这些模型认为地壳是分层的，在富镁岩石为主的下地壳顶部有铁质正长岩。

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.
