SELENE SELENE SELENE (; Selenological and Engineering Explorer), better known in Japan by its nickname , was the second Japanese lunar orbiter spacecraft following the Hiten probe. Produced by the Institute of Space and Astronautical Science (ISAS) and the National Space Development Agency (NASDA), the spacecraft was launched on September 14, 2007. After successfully orbiting the Moon for a year and eight months, the main orbiter was instructed to impact on the lunar surface near the crater Gill on June 10, 2009. The orbiter's nickname, Kaguya, was selected by the general public. It comes from the name of a lunar princess
Antoniadi (lunar crater) unusually flat and smooth, with the central peak being the only notable feature. The floor outside the inner ring is much rougher in texture. The most notable crater on the interior floor lies across the eastern edge of the southern inner ring range. The bottom of Antoniadi crater is measured—by using the laser altimeter (LALT) instrument on board the Japanese Selenological and Engineering Explorer (SELENE) satellite—to be the lowest point on the moon (provisionally named Point Trieste after the Bathysphere Trieste that was the first vehicle to descend to the world's deepest point) and rests 9 kilometers (more than 5.5
