Last week, six people began a year-long mission to Mars simulation on the slopes of Mauna Loa Volcano in Hawaii. The volunteers sealed themselves inside a dome habitat intent on studying how deep space missions can maintain morale on prolonged voyages. Other missions have been 4 and 8 months.
The project, called HI-SEAS, began in 2013 as a way to carry out isolation experiments
in the context of simulated missions to Mars. It uses a solar-powered dome to simulate a Mars habitat. It is funded by NASA and is run by the University of Hawaii at Manoa and Cornell University.
