Mars Analog Stations are important projects of the Mars Society. These are habitations similar to the ones expected to be established on Mars. Their purpose is the preparation of manned Mars missions by simulating human activities on Earth under living and working conditions similar to Mars. They are therefore erected in areas and in a geological environment as similar as possible to the conditions on Mars.
Mission simulations on Mars Analog Stations include scientific research work as well as the activities of daily life and maintenance of the habitation. Type of activities and timelines are as close as possible to actual Mars conditions as well as communications between crew members and with the “ground station”. Mission reports and scientific papers are issued allowing evaluating the mission results and drawing conclusions for the preparation of manned Mars missions.
Crews for missions on Mars Analog Stations are selected through international calls for application. Missions can last from one to two weeks (MDRS) to several months (FMARS). FMARS and MDRS have been fully designed and constructed by the Mars Society with the support of sponsors, and are operational since 2001 (FMARS) and 2002 (MDRS). Mars-Oz and EuroMars are in the construction respectively planning phases.
The Mars Society chapters of the UK, the Netherlands, France, Germany and Austria have Several European.
