Chandrayaan-2 Orbiter's CLASS Spectrometer Maps Abundance of Sodium for the First Time, ISRO Says
The X-ray spectrometer 'CLASS' on the Chandrayaan-2 orbiter has mapped an abundance of sodium on the moon for the first time, according to the Indian Space Research Organisation. 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 national space agency said in a statement on Friday. "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," the statement said. These sodium atoms can be nudged out of the surface by solar wind or ultraviolet radiation more easily than if they were part of the lunar minerals. Also shown is a diurnal variation of the surface sodium that would explain the continuous supply of atoms to the exosphere, sustaining it, the statement said.
