Moon Plain

The Moon Plain extends over 1,500 km2, 18 km north-northeast of Coober Pedy, in central South Australia The locality derives its name from the overall lack of vegetation and a flat hummocky landscape that resembles the surface of the moon.

They are a vast expanse of rocky plains that are quite unusual to anywhere else. The lunar like landscape is so unusual it has been used as the background and set for many movies including Mad Max: Beyond the Thunderdome, Priscilla Queen of the Desert, Pitch Black and The Red Planet.
One of the interesting things about this landscape is that it is littered with beautiful pieces of clear gypsum crystals and gemstones. These are scattered throughout hundreds of pieces of petrified wood, where it is difficult to imagine a vast forest must once have stood.

In planning for future crewed missions to Mars, suitable terrestrial test sites are crucial to development and evaluation of equipment and processes needed for survival and work function. The Moon Plain, northeast of Coober Pedy in the arid region of central South Australia, is potentially one such site. Here the surficial regolith contains abundant hydrated minerals, known to be widely distributed also in the equatorial regions of Mars and identified as a possible source of water in this ice-free region of the planet.
