In a groundbreaking discovery published in the scientific journal Nature Astronomy, scientists have identified a cave on the Moon for the first time. This remarkable find, located on the Mare Tranquillitatis plain, is at least 100 meters deep and holds significant potential as a location for a permanent lunar base. The cave is believed to be one of many hidden in an "underground, undiscovered world," offering a potential solution to several challenges associated with establishing a human presence on the Moon.
As nations compete to establish a sustained human presence on the Moon, the need to protect astronauts from radiation, extreme temperatures, and space weather is paramount. Although the cave's depth poses logistical challenges, necessitating innovative solutions such as abseiling or using jet packs to access its depths, it could eventually become a base for human exploration.
The cave was discovered by Lorenzo Bruzzone and Leonardo Carrer of the University of Trento in Italy, using radar technology to penetrate the opening of a pit on Mare Tranquillitatis, the site of the historic Apollo 11 landing. The cave features a skylight on the Moon's surface, leading to vertical and overhanging walls and a sloping floor. Formed millions or billions of years ago by flowing lava, this structure is comparable to volcanic caves found on Earth, such as Cueva de los Verdes in Lanzarote, Spain.
This discovery is not only significant for potential lunar habitation but also for scientific research. The relatively undisturbed rocks within the cave could provide an extensive geological record, offering insights into the history of the Moon and our solar system. The implications of this research extend beyond the Moon, potentially aiding the exploration of caves on Mars and the search for evidence of life. This pioneering work by Professors Bruzzone and Carrer opens new avenues for space exploration and our understanding of extraterrestrial environments.
