| Key Aspect | Details |
|---|---|
| Event | Chandrayaan-2 observes Coronal Mass Ejections (CMEs) impacting the Moon's exosphere. |
| Agency | ISRO (Indian Space Research Organisation) |
| Date of Observation | May 10, 2024 |
| Instrument Used | CHACE-2 (Chandra's Atmospheric Composition Explorer-2) |
| Key Observation | Tenfold increase in neutral atoms/molecules in the lunar exosphere due to CMEs. |
| Significance | First direct observation of CMEs altering the Moon's exosphere. |
| Moon's Exosphere | Extremely thin, surface-boundary exosphere, influenced by solar activity. |
| CME Composition | Primarily Hydrogen and Helium ions ejected from the Sun's corona. |
| Impact on Moon | Lacks atmosphere & magnetic field, making it highly sensitive to solar outbursts. |
| Scientific Contribution | Validates theoretical models on lunar exosphere dynamics. |
| Chandrayaan-2 Mission | Launched in 2019, orbiter operational despite lander's failed landing. |
| Global Standing | Positions India among leading nations in lunar and planetary research. |
