Lunar Cave Discovery Promises Potential Site for Future Moon Base

Researchers using NASA’s Lunar Reconnaissance Orbiter have uncovered a substantial underground cave on the moon, accessible via an open pit in the Mare Tranquillitatis (Sea of Tranquility). This significant find, situated near the historic Apollo 11 landing site, is seen as an ideal location for future lunar bases due to its natural protective features and stability.
The cave, accessible from the deepest known lunar pit, spans approximately 45 meters in width and extends up to 80 meters in length—roughly the area of 14 tennis courts. Positioned about 150 meters beneath the lunar surface, this cavern is believed to be an empty lava tube, offering a natural shelter against the moon’s extreme conditions.
Lorenzo Bruzzone from the University of Trento, along with his team, utilized radar data and computer simulations to analyze the structure. Their findings, published in Nature Astronomy, reveal that the pit leads to a sloping floor that extends into the cave, providing a feasible entry point. This environment not only protects against cosmic radiation and solar flares but also maintains a relatively stable temperature, which is essential for long-term human habitation.
The concept of utilizing lunar caves for habitation is not new; however, the actual planning for such bases poses several technical challenges. Researchers are exploring how to assess and reinforce the structural stability of these caves, with potential needs for monitoring systems and emergency retreat areas. The caves’ interiors, which may also contain water ice, offer valuable research opportunities that could reveal more about the moon’s volcanic history and formation.
Katherine Joy, a professor in Earth sciences at the University of Manchester, emphasizes the protective benefits of the thick cave ceilings against the lunar surface’s harsh conditions. Meanwhile, Robert Wagner from Arizona State University highlights the challenges of accessing the cave, noting the need for significant infrastructure to safely navigate the steep, debris-laden slopes leading into the pit.
This discovery marks a crucial step forward in the ongoing exploration and potential colonization of the moon, aligning with international space agencies’ goals to return humans to the moon and establish semi-permanent bases.
