New Delhi: This week, the Chandrayaan-3’s Propulsion Module created fresh interest after it slipped back into the Moon’s gravity zone during its long Earth-bound orbit. What looked like a quiet post-mission phase has turned into an unexpected scientific opportunity, giving researchers a close look at how Earth and lunar gravity can reshape a drifting spacecraft’s path.

What started as a simple return-orbit experiment has ended up becoming a cosmic detour that pushed the spacecraft back into the Moon’s gravity field, giving scientists a rare chance to observe how Earth and lunar gravity pull a drifting satellite in different directions. ISRO says this whole event has offered “valuable insights and experience from mission planning, operations, flight dynamics perspectives, and especially e
