Chandrayaan-2 spectrometer maps sodium on moon

In a recent work published in 'The Astrophysical Journal Letters', Chandrayaan-2 mapped the abundance of sodium on the Moon for the very first time using CLASS (Chandrayaan-2 Large Area Soft X-ray Spectrometer).

The study finds that a part of the signal could be arising from a thin veneer of sodium atoms weakly bound to the lunar grains.
