Japanese Lunar Exploration Program 2007, after being delayed several times. SELENE-2, Japan's first lunar lander and rover, is expected to be launched in the 2020s. The program also includes a lunar sample return mission (SELENE-3), a mission to Mars to collect data for future manned expeditions (MELOS), participation in the Mars international sample return mission, and an advanced lander for future human missions to the Moon. The eventual goal is to participate in an international lunar outpost program, in which Japanese crews would stay on the lunar surface for a prolonged period of time and promote scientific research and environment utilization.

SELENE-2 SELENE-2 SELENE-2 , or the Selenological and Engineering Explorer 2, is a cancelled Japanese robotic mission to the Moon that would have included an orbiter, a lander and a rover. It was intended as a successor to the 2007 SELENE (Kaguya) lunar orbiter. The lander would have targeted lava tubes and other permanently shadowed areas, which function as cold trap volatiles such as water. Water ice could be processed by future missions to produce spacecraft propellant (LOX/H). The orbiter would have a mass of 700 kg. The lander would have a mass of 1,000 kg, and would be able to
