The Moon is a small planetary body that has separated into a crust, a mantle and a core, but has not been disturbed by plate tectonics. It is therefore of tremendous value for understanding the evolution of planetary interiors. However, the composition of the lunar mantle remains uncertain. In January, the Chinese spacecraft Chang’e-4 landed in a large impact crater on the far side of the Moon and deployed its rover, Yutu2. On page 378, Li et al.1 use spectral observations by Yutu2 to infer the presence of olivine and low-calcium pyroxene — minerals that might have originated in the lunar mantle
