According to PTI report, This observation would help understand the lunar exosphere, very thin atmosphere of the Moon, and the impact of space weather on its surface, the Bengaluru-headquartered space agency said.
Launched on July 22, 2019, from Sriharikota using the GSLV-MkIII-M1 rocket, Chandrayaan-2 carried eight experiment payloads.
On August 20, 2019, Chandrayaan-2 was successfully inserted into the elliptical orbit around the Moon.

Although communication with the Vikram lander was lost during its September 7 landing attempt, the Orbiter remains fully operational and continues to function in a 100 km x 100 km orbit around the Moon.
According to an ISRO release, one of the payloads (on-board Chandrayan-2), Chandra’s Atmospheric Compositional Explorer 2 (CHACE 2) has recorded the effects of the Coronal Mass ejections from the Sun on the lunar exosphere.
