Lava caves could be useful as outposts for the human exploration of the Moon. Lava caves or lava tubes are formed whenthe external surface of the lava flows cools more quickly to make a hardened crust over subsurface lava flows. The lavaflow eventually ceases and drains out of the tube, leaving an empty space. The frail part of the ceiling of lava tube couldcollapse to expose the entrance to the lava tubes which is called a pit crater. Several pit craters with the diameter of around100 meters have been found by analyzing the data of SELENE and LRO lunar missions. It is hard to use these pit cratersfor outposts since these are too large in scale. In this study, small scale pit craters which are fit for outposts have beeninvestigated using the NAC image data of LROC. Several topographic patterns which are believed to be lunar caves havebeen found and the similar pit craters of the Earth were compared and analyzed to identify caves. For this analysis, theimage data of satellites and aerial photographs are collected and classified to construct a database. Several pit cratersanalogous to lunar pit craters were derived and a morphological pit crater model was generated using the 3D printer basedon this database.
