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.

Gill (lunar crater) pair of small craters lie along the northern rim, and Gill A intrudes slightly into the western outer rim. The interior floor is relatively level, and is marked by several craterlets. On June 11, 2009, the Japanese SELENE lunar orbiter spacecraft was deliberately crashed into the surface of the Moon to the southeast of Gill. The impact site was at selenographic coordinates 65.5 S, 80.4 E. The flash from the impact was successfully observed from Mount Abu Observatory in Guru Shikhar, India. and by the Anglo-Australian Telescope. By convention these features are identified on lunar maps by placing the letter
