Asimov Jr. Lunar Rover
A simulated 5-day Mars mission took place in the Giant Ice Caves of Dachstein, Austria, created by the Austrian Space Forum and international research partners in April-May 2012. Here, a lunar rover created by the Part-Time Scientists, Asimov R3, undergoes testing in the King Arthur Dome. High humidity inside poses quite a challenge for the little rover.
