India and Japan’s Chandrayaan-5 (also called LUPEX) mission is advancing to the design phase, aiming to detect water and water-ice at the Moon’s south pole.
Scheduled for launch in 2027–28 on Japan’s H3 rocket, the 6.5-tonne lander and a 350-kg rover equipped with seven instruments (from ISRO, JAXA, ESA, and NASA) will perform in-situ scientific experiments.
The project marks a strong symbol of global collaboration and follows India’s successful Chandrayaan-3 mission.
