One-Year Mock Mars Crew 'Returns to Earth': HI-SEAS Photos

HI-SEAS One Year Crew

After living in relative isolation for a year, the six crew members of the most recent HI-SEAS mission rejoined society on Aug. 28, 2016.

The HI-SEAS Isolation Dome

The dome habitat where crew members lived is on the slopes of Mauna Loa, on the island of Hawaii. The crew cannot leave the habitat without wearing a space suit. They have limited contact with friends, family and Mission Support. The program is run by the University of Hawaii Mānoa.

A Happy Return

Members of the HI-SEAS crew step outside the dome habitat for the first time (without a space suit) in one year. Some greeted family members, and met scientists they had only communicated with digitally.

Crew and Mission Support

Members of the HI-SEAS isolation crew pose for a photo with members of the project's Mission Support, which includes working scientists and volunteers. The crew members (kneeling in front) are (l to r): Sheyna Gifford, Tristan Bassingthwaighte, Christiane Heinicke, Cyprien Verseux, Carmel Johnston, and Andrzej Stewart.

The Joys of Earth

HI-SEAS crew member Christiane Heinicke enjoys fresh raspberries, something she sorely missed while living in the HI-SEAS isolation habitat for a full year. The crew members can only eat food that is "shelf stable" and could potentially be shipped to space, which means no fresh fruits and vegetables.

Habitat Solar Panels

A solar panel array provides electricity to the habitat. On cloudy days, crew members reduce their energy usage, as well as minimizing heating and cooking.The habitat is largely self-sufficient.

Mars, on Earth

The volcanic rock that makes up Mauna Loa is extremely jagged, and almost no vegetation grows there. As a result, the mountain is an ideal analogue for Mars.

The Road to Mars

The road leading up to the HI-SEAS isolation habitat is surrounded by a barren landscape.
