The Mare Tranquillitatis pit has been associated with a lava tube. Lunar lava tubes are lava tubes on the Moon formed during the eruption of basaltic lava flows. When the surface of a lava flow cools, it hardens and the lava can channel beneath the surface in a tube-shaped passage. Once the flow of lava diminishes, the tube may drain, forming a ...
A lunar lava cave potential has long been suggested and discussed in literature and thesis. [27] Any intact lava tube on the Moon could serve as a shelter from the severe environment of the lunar surface, with its frequent meteorite impacts, high-energy ultraviolet radiation and energetic particles, and extreme diurnal temperature variations.
Common features shared by lunar rilles and similar structures on other bodies suggest that common causative mechanisms operate widely in the solar system. Leading theories include lava channels , collapsed lava tubes, near-surface dike intrusion, nuée ardente (pyroclastic cloud), subsidence of lava-covered basin and crater floors, and tectonic ...

Thurston Lava Tube in Hawaii Volcanoes National Park, Hawaii. The step mark, more visible on the right wall, indicates the depth at which the lava flowed for a period of time. Rare characteristics of lava tubes are lava pillars. This is the Manjanggul lava pillar located in the Manjanggul lava tubes, on the island of Jeju-do, Korea.
Radar analysis also revealed the presence of a buried crater that formed when a large object slammed into the lunar surface as well as helped map ancient lava flows under the moon.
The pit was created by a lunar lava tube, and is currently the deepest known lunar pit with a radius of at least 100 meters (328 feet). The lunar feature is notable for being the first lunar cave proven to exist beyond theoretical frameworks, [ 1 ] [ 2 ] [ 3 ] and of being direct evidence of the existence of natural lunar shelter that could ...
[43] [44] An area displaying a lava tube is the Marius Hills region. [45] In 2008, an opening to a lava tube in this area may have been discovered by the Japanese Kaguya spacecraft. [46] The skylight was photographed in more detail in 2011 by NASA's Lunar Reconnaissance Orbiter, showing both the 65-meter-wide pit and the floor of the pit about ...
