In the vast open spaces of southern Utah, Reuters photographer Jim Urquhart recently paid a visit to the Mars Desert Research Station (MDRS). Built and operated by a space advocacy group called the Mars Society, the research facility is investigating the feasibility of human exploration of Mars, using the Utah desert's Mars-like terrain to simulate working conditions on the red planet. Since 2000, more than 100 small crews have served two-week rotations in the MDRS, conducting research in an on-site greenhouse, observatory, engineering area, and living space. Urquhart was able to accompany members of the Crew 125 EuroMoonMars B mission inside the MDRS facility, and on a simulated trip to collect Martian geological samples.
