Hans van Ot Woud, a mapping researcher and the health and safety officer of Crew 125 EuroMoonMars B mission, collects geologic samples to be studied at the Mars Desert Research Station (MDRS) outside Hanksville in the Utah desert, on March 2, 2013. The MDRS aims to investigate the feasibility of a human exploration of Mars and uses the Utah desert’s Mars-like terrain to simulate working conditions on the red planet. Scientists, students and enthusiasts work together developing field tactics and studying the terrain. All outdoor exploration is done wearing spacesuits and carrying air supply packs and crews live together in a small communication base with limited amounts of electricity, food, oxygen and water. Everything needed to survive must be produced, fixed and replaced on site. (Reuters/Jim Urquhart)
