The Lunar Polar Exploration Mission (LUPEX) (also called Chandrayaan-5) is a planned joint lunar mission by ISRO and JAXA. The mission would send an uncrewed lunar lander and rover to explore the south pole region of the Moon no earlier than 2028. It is envisaged to explore the permanently shadowed regions and to determine the quantity and quality of water on the Moon. JAXA will provide the H3 launch vehicle, 350 kg lunar rover along with instruments and ISRO will provide the lander and few rover instruments.

LUPEX will follow the planned lunar sample-return mission Chandrayaan-4.
