Lunar Lava Tube Entrances

Part of an in-progress environment concept art project exploring what future underground habitats may look like on the Moon. Using actual Lunar Reconnaissance Orbiter imagery accessed through https://quickmap.lroc.asu.edu/, these concepts show what a sealed entrance to a lava tube may look like with three options based on known and potential lava tube entrances on the Moon.

A white and blue wall at the bottom of a pit on the Moon.

A dome like structure that houses an elevator to the center of a lava tube.

"Aerial" view of a sinuous rille with a large entrance to the underground and some exterior infrastructure.

Photos of collapses and sketches of potential entrance designs.
