CAVES 2011 compilation

In 2011 five astronauts went underground for ESA's CAVES training adventure. ESA's Tim Peake and Thomas Pesquet were joined by Randolph Bresnik from NASA, Norishige Kanai from Japan and Sergey Ryzhikov from Russia.
CAVES, an abbreviation of Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills, prepares astronauts to work safely and effectively and solve problems as a multicultural team while exploring uncharted areas following space procedures.
