Sergey Kud-Sverchkov acting as Survey Engineer introduces day 5 of the CAVES 2014 campaign. The crew has returned from their advance camp and continues their exploration of the cave system.

Held each year, CAVES teaches astronauts to explore the underground system of the Sa Grutta caves in Sardinia, Italy, as a team, delving deep underground to perform scientific experiments as well as chart and document their activities.

The CAVES course – Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills – is run by the European Astronaut Centre to simulate spaceflight. Seasoned International Space Station astronauts as well as rookies participate in the course and share experiences while learning how to improve leadership, teamwork, decision-making and problem-solving skills.

The cavenauts participating in this year's campaign are ESA astronaut Luca Parmitano, NASA astronaut Scott Tingle, Roscosmos cosmonauts Alexander Mirsurkin and Sergey Kud-Sverchkov and ESA engineer & Eurocom Matthias Maurer.
