Chandrayaan-2 Captures Sun’s Fury on Moon: First Direct Observation of Solar CME Impact

In a historic scientific breakthrough, India’s Chandrayaan-2 lunar orbiter has captured the first-ever direct observation of a solar coronal mass ejection (CME) impacting the Moon. The Indian Space Research Organisation (ISRO) confirmed that data from the Chandra’s Atmospheric Composition Explorer-2 (CHACE-2) instrument recorded a dramatic increase in the total pressure of the dayside lunar exosphere, the Moon’s extremely thin atmosphere, during the CME event.

The observations revealed that the density of neutral atoms in the lunar exosphere increased by more than an order of magnitude, offering unprecedented insights into space weather effects on the Moon. Scientists note that this validation of long-standing theoretical models is crucial for understanding the interaction between solar events and lunar atmospheric dynamics.

The data from CHACE-2 not only enhances our knowledge of the Moon’s exosphere but also carries vital implications for future lunar missions, including astronaut safety and the planning of long-term lunar habitats. Exposure to solar CMEs can pose significant risks to spacecraft and potential colonies, making Chandrayaan-2’s observation a landmark in space exploration and planetary science.

Dr. [Name], a scientist at ISRO, said, “This is a pivotal moment for India’s lunar research. CHACE-2’s observations provide direct evidence of how solar activity can alter the Moon’s environment, information that is critical for upcoming manned and unmanned lunar missions.”

This milestone underscores India’s growing leadership in space exploration, as Chandrayaan-2 continues to deliver cutting-edge data on the Moon, reinforcing ISRO’s position among the world’s top space agencies.
