India’s pioneering mission bolsters idea that Moon’s surface was molten

The first-ever analysis of soil near the Moon’s south pole has found further evidence that the lunar surface melted shortly after it formed. The data come from India’s pioneering Chandrayaan-3 mission, which deployed a rover on the Moon last August that found the soil mainly comprised the mineral ferroan anorthosite. Previous landers have found similar results at other locations, suggesting the composition of the surface is uniform. This supports the theory that the Moon originated from material scattered into space when a large impactor struck the newly formed Earth.
