NASA explores lunar crater for underground cave
The article concerns NASA's exploration of the "Marius Hills" crater on the Moon's surface, which is believed to potentially lead to an underground cave offering protection for astronauts from radiation and harsh temperatures. The mission, known as "Ground-Penetrating Instruments for Exploring the Marius Lunar Crater" (GIMLI), employs techniques such as ground-penetrating radar, seismic sensors, and gravity field measurements to determine the presence of a lava tunnel or cave beneath the lunar surface. If found, this cave could provide a safe shelter for future missions, given the high radiation levels on the Moon's surface—about 2.6 times that of the International Space Station and 200 times that of Earth—posing health risks to astronauts. The study aims to understand the subsurface structure and the history of volcanic activity, as the crater walls reveal layers of ancient debris and lava, thereby enhancing our understanding of volcanic formations on the Moon.
