Earth analogues are natural field sites with conditions that resemble one or more conditions found in planetary bodies. The importance of those extreme sites are crucial for study limits of life, habitability and for the space missions tools and techniques test before flying. Those extreme sites can be interpreted as natural laboratories. This session also welcomes abstracts on scientific investigations in planetary analogues fieldwork that are being carried out with Unmanned Aerial Vehicles (UAVs) a.k.a. drones.
