ESA CAVES
CAVES (Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills) is a European Space Agency (ESA) astronaut training course in which international astronauts train in a space-analogue cave environment. Designed at the European Astronaut Centre, the course aims to prepare astronauts for safe and efficient long duration spaceflight operations by means of a realistic scientific and exploration mission within a multicultural, ISS-representative team.
