Chandrayaan-1 finds clues to a Moon basin lost in time

New data from Chandrayaan-1 supports an ancient impact basin in the Mare Australe region. Mineralogical evidence shows orthopyroxene distribution delineating the obliterated Australe Basin's boundary. This suggests a dual-impact scenario involving two basins in the lunar south. The basalts of Mare Australe exhibit unusual mineralogy compared to typical lunar basalts. This discovery aids in reconstructing the Moon's early impact history.
