Researchers from the University of Trento have confirmed the existence of a significant lunar cave located in the Sea of Tranquility, utilizing radar data from NASA's Lunar Reconnaissance Orbiter. This cave, which may extend over 100 meters below the surface, is believed to have formed from ancient lava flows and could offer protection for future astronauts from the Moon's harsh conditions, such as extreme temperatures and radiation. The study suggests a network of similar caves may exist, with implications for human habitation and resource exploration on the Moon. As NASA prepares for its Artemis missions, these findings highlight the potential for utilizing lunar caves as sites for sustainable human presence. This discovery not only supports theories that have persisted for over 50 years but also paves the way for future lunar colonization strategies. The possibility of mining resources within these caves could also significantly reduce the costs associated with lunar missions.
