SELENE (Selenological and Engineering Explorer), nicknamed Kaguya after a lunar princess in the ancient Japanese folklore "The Tale of the Bamboo Cutter", is the second Japanese mission to the Moon. Launched in September 2007, it was "the largest lunar mission since the Apollo program". The mission featured three separate space craft, the main orbiter (Kaguya), the small relay satellite (Okina), and the VLBI satellite (Ouna).
