Japanese Lunar Exploration Program the LUNAR-A mission, and a small data relay satellite. SELENE-3 aims to return about 100 grams of samples from the Moon surface. It will be launched around 2020. However, due to financial issues JAXA is currently facing, this mission may be merged into the option-3 of SELENE-X. SELENE-X will be launched in the late 2010s, in view of Japan’s participation in Humans Lunar Activities foreseen. The SELENE-X may perform either of the following demonstrations: There are other options under study, and will be determined after the international exploration strategy has been clarified.

Lunar Orbital Platform-Gateway Lunar Orbital Platform-Gateway The Lunar Orbital Platform-Gateway (LOP-G) is a proposal for a lunar-orbit space station intended to serve as an all-in-one solar-powered communications hub, science laboratory, short-term habitation module, and holding area for rovers and other robots. The science disciplines to be studied on the Gateway are expected to include planetary science, astrophysics, Earth observations, heliophysics, fundamental space biology and human health and performance. The Gateway is designed to be developed, serviced, and utilized in collaboration with commercial and international partners. It will also serve as the staging point for crewed and robotic lunar exploration and a staging point
