On 18 October 2017, the Japanese space agency JAXA reported that its lunar orbiter probe Selenological and Engineering Explorer (SELENE) had discovered a large cave below the surface of the Moon. The probe had discovered a large cave with an opening around 50 m across, descending around 50 m below the surface. The lunar radar sounder on board showed the opening leads to a much larger cave formed by volcanism, similar to how lava tube caves form on Earth. The overall size of the cave, which is in the Marius Hills region of the lunar near side, is thought to be around 50 km long and 100 m wide. This cave is a likely spot for a future manned lunar base and may contain deposits of water ice.
