A landscape with a dormant crater and a satellite is photographed from the top of volcano Mauna Kea, about a million years old, which raises 13,796 ft above sea level. Hawaii, Big Island.
Space suits are photographed inside the dome on volcano Mauna Loa, where six researchers have been living for eight months in isolation for the NASA human performance study Hawaii Space Exploration Analog and Simulation. During the months of isolation the researchers can leave the dome only for brief excursions, wearing the spacesuits with a helmet and oxygen supply. Hawaii, Big Island.

Chairs are photographed on volcano Mauna Loa on the day when six researchers who lived eight months of confinement in a dome came out of it for the end of the HI-SEAS (Hawaii Space Exploration Analog and Simulation) mission, whose purpose is to monitor the psychological response of human beings in condition of isolation in an unearthly environment, in perspective of the launch of scientific trips to Mars involving the presence of human beings of the planet.
