Why in news
ISRO and astronomer Dr. Jonathan McDowell reported that the Moon's gravitational influence significantly altered the orbit of the Chandrayaan-3 propulsion module in November 2025.
Background
The Chandrayaan-3 propulsion module experienced a close encounter with the Moon in November 2025. The resulting new orbit is described as much larger, tilted, and more extreme than its previous trajectory.
