SELENE-2 /ˈsɛlɪn/, 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.[3] It was intended as a successor to the 2007 SELENE (Kaguya) lunar orbiter.[4]


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).[1]


The orbiter would have a mass of 700 kg.[3]


The lander would have a mass of 1,000 kg, and would be able to deliver up to 340 kg[1] of payload, including the rover. Its mission would last two weeks.[3]


The rover would have a mass of 100 kg, and it would operate for two weeks.


One option JAXA was investigating in 2006, was to integrate a small data relay satellite and penetrators into the mission.[5]
