Underground day 3.
Day 3 of the astronauts’ caving adventure is spent exploring wetter regions of the Sa Grutta caves.
An international crew of six astronauts are training for a caving adventure designed to prepare them for spaceflight. There are many similarities to spaceflight such as a lack of day–night cycle, sensory deprivation, minimal hygiene and the necessity to work as a team and solve problems together.
After a week of training they entered the caves to spend six days living and working underground.
