Chandrayaan-2 Orbiter’s X-ray spectrometer ‘CLASS’ has mapped an abundance of sodium on the moon for the first time, as per the Indian Space Research Organisation (ISRO).
As Chandrayaan-1’s X-ray Fluorescence Spectrometer (C1XS) detected sodium from its characteristic line in X-rays, this opened up the possibility of mapping the amount of sodium on the Moon.
The abundance of sodium was mapped in a recent work published in ‘The Astrophysical Journal Letters’ for the first time using CLASS (Chandrayaan-2 Large Area Soft X-ray Spectrometer), the national space agency.
Built at the U R Rao Satellite Centre of ISRO in Bengaluru, CLASS provides clean signatures of the sodium line thanks to its high sensitivity and performance,”.
