Scientific interest in lunar water ice, particularly in permanently shadowed regions near the poles, is high due to its implications for future human missions and resource utilization. Therefore, polar regions are prime targets for sample return missions.

A sample return mission, like Chandrayaan-4 is anticipated to be, necessitates the capability to lift off from the Moon and rendezvous with an orbiting spacecraft. Therefore, a lunar ascent module is a critical technological requirement.

Chandrayaan-3 successfully achieved a soft landing and conducted in-situ scientific experiments. Chandrayaan-4 is widely expected to focus on sample return, building upon the technological advancements of its predecessors, to enable more in-depth scientific study on Earth.
