Chandrayaan-2 Orbiter detects Argon-40 in lunar exosphere



CHENNAI: The Chandra’s Atmospheric Composition Explorer-2 (CHACE-2) payload aboard the Chandrayaan-2 Orbiter has detected Argon-40, said Indian Space Research Organisation (ISRO).

According to ISRO, the Orbiter that is orbiting the moon has detected Argon-40 from an altitude of about 100 km.

Argon-40 (40Ar), which is one of the isotopes of the noble gas Argon, is an important constituent of the lunar exosphere, ISRO said on Thursday.

Planetary scientists prefer to call the thin gaseous envelope around the Moon as the ”Lunar exosphere” since it is so tenuous that the gas atoms very rarely collide with each other, ISRO said.
