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.
Three types of rille are found on the lunar surface: Sinuous rilles meander in a curved path like a mature river, and are commonly thought to be the remains of collapsed lava tubes or extinct lava flows. They usually begin at an extinct volcano, then meander and sometimes split as they are followed across the surface.

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.
[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 ...
The new study, published recently in the Journal of Geophysical Research: Planets, revealed lunar lava likely flowed across the landscape in this part of the moon billions of years ago.
An abundance of domes, cones, and volcanic rilles and channels is characteristic of the Marius Hills. The Lunar Reconnaissance Orbiter photographed a pit that could be a skylight in a lava tube, indicating that part of its roof has collapsed, as often happens after lava tubes cease to be active.
