ISRO milestone: Chandrayaan-2 makes first ever observation of Sun's impact on Moon; key details

India's Chandrayaan-2 orbiter has achieved a groundbreaking first, detecting the impact of solar Coronal Mass Ejections on the Moon's tenuous atmosphere. Using the CHACE-2 instrument, scientists observed a significant surge in the Moon's exospheric pressure and density when hit by these powerful solar bursts. This direct observation validates long-held theories and offers vital insights for future lunar missions and habitat planning.
