When human space travel made its transition from pipe dream to reality, one of the unknowns humans contended with concerned not just the physics of space, but the psychology of it. How would the human mind react to the final frontier? Would microgravity, combined with the isolation of a spaceship, cause a kind of claustrophobia? Would propulsion outside of Earth's bounds, in the end, cause astronauts to experience a psychic break? Was there such thing, as science fiction writers had long feared, as "space madness"?
Space, fortunately, does not drive us crazy. But that doesn't mean we've stopped caring about the effects its new environments will have on our psychology. The new version of the old "space madness" question is how time away from our home planet will affect us—in the long term. What could life on Mars do to that that other cosmic mystery: the human emotional state?
NASA is hoping to find out. This week, in partnership with the University of Hawaii at Manoa, the agency launched the latest version of its Mars simulation experiment, the Hawaii Space Exploration Analog and Simulation mission. On Hawaii's Big Island, 8,200 feet above sea level, conditions are as Martian as they can be on Earth: Mauna Loa's volcanic soil is quite similar to the volcanic regolith that can be found on Mars. HI-SEAS in general aims to replicate, as closely as is possible on Earth, what life would be like on Mars—and its latest iteration will put human emotions to the test.
