SELENE-2 /ˈsɛlɪniː/, 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.

[5][6][7][8] The mission would send an uncrewed lunar lander and rover to explore the south pole region of the Moon no earlier than 2026.

[10] 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/H2).

One option JAXA was investigating in 2006, was to integrate a small data relay satellite and penetrators into the mission.
