Mars on Earth – Analogues

Field Site Analogues and Facilities 

Terrestrial analogues are sites (both natural and artificial) that have specific characteristics that simulate properties of a targeted planetary space environment. Numerous field sites around the world have been identified as having one or more physical similarities to specific locations on Mars. Examples may include geological, geomorphic, geochemical, or climatic parameters comparable in nature.

For decades, teams have utilized these environments for scientific, technological, and/or operational experiments that:

• Allow researchers to develop and test conceptual models or make scientific measurements about properties or processes inferred on Mars; and
• Can be used to inform future mission planning for both human and robotic activities.

IMEWG Mars Analog Coordination Working Group

IMEWG is currently coordinating the development of an online, interactive database of terrestrial field sites that serve as Mars analogues. A goal of this activity is to provide the broader scientific community with access to information on Mars analoge sites using an interactive 3D Earth model. The initiative also offers an important opportunity to connect Mars research and technology objectives with specific site capabilities to accelerate science innovation and assist mission planning campaigns.
