A group of international scientists confirmed that there is a large underground tunnel beneath the Moon's surface that has the potential to shelter future astronauts in missions.
The tunnel is reportedly capable of shielding astronauts from the lunar temperature and extreme radiation on the surface.
Scientists Observe Subsurface Openings on the Moon's Surface
A recent study from Nature Astronomy revealed that scientists have been observing several potential subsurface openings on the surface of the Moon. More than 200 shadow-drenched openings have been discovered since 2009.
The study reported that a pit located in the Mare Tranquillitatis region of the Moon has the potential to shelter astronauts. The data suggests that the tunnel has an expansive hidden area, making it a promising location for future lunar missions.
The scientists used data capture through NASA's Lunar Reconnaissance Orbiter's Miniature Radio-Frequency (Mini-RF) instrument back in 2010. The data revealed that the cave could extend by tens of meters and beyond.
Scientists Seek Shelter for Lunar Missions Amid Extreme Conditions
According to NASA, the surface of the Moon can hit up to 260 °F (127 °C) on its sunlit side, while the shadowed side's temperature can go down to 280°F (-173°C). These extreme opposite temperatures are considered fatal to the human body.
However, the lunar cave could provide a solution to astronauts during missions. The pits are estimated to have a temperature of 63 °F (17 °C) and are known for fluctuating very little compared to the surface.
Settling in underground caves could also pose a greater shield for astronauts. The space is full of micrometeorite impacts which could hit them at any time. In addition, the Sun's radiation is 150 times more potent on the Moon than on Earth.
NASA is now focused on launching crewed exploration to the Moon before planning to explore more information from Mars.
