Underground day 6, last day.<br /><br />The cavenauts pack their bags and tents and start the six-hour climb back to Earth's surface. <br />So ends the CAVES 2012. All that remains for the astronauts is to write their mission reports.<br /><br />An international crew of six astronauts trained on 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.<br /><br />After a week of training they entered the caves to spend six days living and working underground.<br /><br />Copyrights: ESA--V.
