India's Ambitious Chandrayaan-4 Mission: Returning Moon Soil Samples

India's space agency, ISRO, is planning a lunar sample-return mission called Chandrayaan-4, following the success of its recent moon landing. The mission will involve sending four modules to the moon across two launches, with the aim of collecting samples from the lunar south polar region and returning them to Earth. The mission concept is similar to NASA's effort to bring back Martian samples. The specific mission plan is yet to be announced, but it is expected to take place within the next five to seven years.
