Exploring new worlds

Underground day 4.

In a room with a beautiful pond the astronauts enjoy a meal before descending even deeper into Earth.

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.
