The Australia Mars Analog Research Station (MARS-Oz) is a project being planned by the Mars Society to conduct geological exploration under constraints similar to those found on Mars, to develop field tactics based on those explorations, to test habitat design features and tools, and to assess crew selection protocols. The Mars Society of Australia is seeking sponsors to construct MARS-Oz in the Lake Frome Plains east of Arkaroola, and a primary focus of this MARS will be the search for ancient fossils.
