Moon Cavern Detected via Radar Scans by Lunar Orbiting Vehicle
Rewritten Article:
Hey there! Have you heard about that intriguing tunnel found on the Moon's surface? It's hidden in the Mare Tranquillitatis, a region known for being the landing spot of Apollo 11 in 1969.
The Hidden Gem Under the Lunar Surface
This secret tunnel lies within the deepest pit known on the Moon, a pit that formed due to either the roof collapse of a lava tube or a void structure brought about by tectonic activities. Researchers analyzed side-looking radar images taken by the Lunar Reconnaissance Orbiter's Mini-RF instrument between 2009 and 2011 to search for potential cave structures in the pit.
Using 3D radar simulations of the pit and hypothetical cave geometries, the team discovered a tunnel between 98 feet (30 meters) to 262 feet (80 meters) in length, approximately 148 feet (45 meters) wide, and stationary or sloping with a maximum steepness of 45 degrees. Their research, recently published in Nature Astronomy, offers exciting possibilities for lunar exploration and even human presence on the Moon.
Lunar Caves: The Next Big Thing for Space Exploration
The team argued that studying lunar caves through future robotic missions could offer valuable insights into the lunar subsurface, providing crucial information about the evolution of lunar volcanism. Moreover, exploration could verify the presence of stable and radiation-shielded environments, making them ideal for future human utilization.
Interestingly, data from the LRO suggests that the shadowy overhangs of lunar pits help maintain a relatively temperate environment. In 2022, temperatures in some lunar pits were reported to hover around 63° Fahrenheit (17.2° Celsius).
Study co-authors Leonardo Carrer and Lorenzo Bruzzone pointed out that building a lunar base in a cave offers several advantages compared to a surface base:
- Protection from cosmic rays and solar radiation.
- Thermal stability due to the temperature consistency in lunar caves.
- Micrometeorite protection due to the natural shield provided by cave rocks.
- Potential proximity to sources of water ice or other minerals.
What Comes Next for Researching the Lunar Interior?
A semi-permanent presence on the Moon would enhance our ability to conduct research missions on the lunar surface and serve as a launchpad for outer solar system missions.
Carrer and Bruzzone also believe that history could be preserved in these lunar caves. The rocks within these caves, untouched by the harsh lunar environment, could provide significant insights into the Moon's volcanic activity and the composition of its interior.
While we currently lack an orbiter equipped with more advanced radar instruments, discovering this cave serves as an enticing sneak peek into the science that could be done in these lunar recesses. The finding is captivating, both for expanding our understanding of the Moon's history and potentially laying the groundwork for human presence on it.

The newly discovered tunnel on the Moon is part of a broader volcanic structure within the Mare Tranquillitatis. The pit and the potential cave are most likely formed through volcanic processes, just like lava tubes found on Earth. The cave's dimensions are not precisely measured, but the researchers believe it offers enough space for astronauts and could host valuable insights into lunar geology.

- Intriguingly, the tunnel discovered on the Moon's surface within the Mare Tranquillitatis might be part of a larger volcanic structure, similar to lava tubes found on Earth, hinting at a future where astronauts might explore its depths.
- The brightness and radar reflections of this hidden passage could provide scientists with valuable insights about the lunar subsurface, potentially shedding light on the Moon's geological history and the evolution of its volcanism.
- If the dimensions of the tunnel are as extensive as estimated, it could offer an ideal environment for human exploration, providing protection from cosmic rays, thermal stability, and shielding against micrometeorites, making it a candidate for future human habitation.
- The future of space exploration could see the study of lunar caves becoming a significant focus, as they offer the promise of unveiling the Moon's secrets, preserving history, and paving the way for a sustainable human presence on the lunar surface.
