Why astronauts train in the dark of underground caves
In short: Before heading into the void of space, astronauts descend 800 meters into the earth. This video explores how the subterranean world of Sardinia serves as a high-stakes laboratory for mastering human behavior and teamwork in extreme environments.
The CAVES program is a two-week cooperative adventure designed to prepare astronauts for the psychological and physical demands of spaceflight. By spending six nights underground, participants from agencies including ESA, NASA, JAXA, and CNSA must learn to function in a multicultural team within one of Earth's last unexplored frontiers.
The training emphasizes shared protocols between speleologists and explorers. Core safety principles involve moving deliberately, verifying equipment before reliance, and staying perpetually conscious of a teammate's position. These parallels highlight how cave exploration mirrors the isolation and technical precision required for space missions.
