Six scientists have simulated living on Mars in a four-day long experiment.
The participants - dubbed Ramonauts - simulated living conditions on the Red Planet with a mock-up built in the Negev desert in Israel.
The project named D-MARS - Desert Mars Analog Ramon Station - ended on Sunday according to Israel's Science and Technology Ministry.
The experiment was held near the isolated Israeli township of Mitzpe Ramon, whose surroundings resemble the Martian environment in its geology, aridity, appearance and desolation, the ministry said.
The researchers were investigating various fields relevant to a future Mars mission, including satellite communications, the psychological effects of isolation, radiation measurements and searching for life signs in soil.
