Several astronaut candidates will be able to carry out an analog space mission for a whole week, at a volcanic cave on Terceira Island (the Azores). Due to its characteristics, Gruta Natal sets up the perfect environment to simulate mission on Mars or the Moon, facilitating training, technology testing, and data collection, among other scientific activities. CAMões is the name of this pioneering project in national territory, with INESC TEC as one of the promoters.
