♦ Chandrayaan-2 has made the first-ever observation of the effects of Coronal Mass Ejections (CMEs) from the Sun on the Moon’s exosphere.

♦ The Indian Space Research Organisation (ISRO) announced this on 18 Octobr 2025.

♦ The observation was made using the Chandra’s Atmospheric Composition Explorer-2 (CHACE-2) instrument onboard the orbiter.

♦ During a rare solar event on May 10, 2024, a series of CMEs impacted the Moon, leading to a significant increase in the total pressure of the dayside lunar exosphere — the extremely thin atmosphere surrounding the Moon.

♦ 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.
