Why astronauts head underground before they head into orbit
In short: To prepare for the isolation of space, astronauts undergo the CAVES mission. This video explores how living in dark, humid, and confined underground environments helps scientists study the psychological and technical challenges of long-duration spaceflight.
The CAVES mission involves astronauts living in an isolated underground environment for five days. This training simulates the confinement, limited privacy, and technical difficulties faced during space missions. By using artificial light in constant darkness, researchers can observe how the absence of natural daylight cues alters sleep patterns, circadian rhythms, and the perception of time and colour.
During the mission, participants perform tasks such as geological and microbiological sampling, mapping, and photography. This work provides data for studying unmapped caves and helps refine sampling methods for future planetary missions. The trainees undergo debriefings upon emerging from the cave, mimicking the protocols used after actual space missions.
