CHAPEA 1 simulates year\u002Dlong stay on the red planet for four \u0027analog astronauts\u0027 — minus the low gravity, Mars time and the vacuum of space
The four crew members may not be “real” astronauts, but the selection process included the same physical and psychological testing as other astronaut candidates, and requirements included a degree in one of the STEM fields as well as professional, piloting or military experience.
“What CHAPEA is really about is Mars-realistic conditions in terms of resource restrictions,” Bell said. “Isolation confined with the living space being one of them. But we’re also restricting the crew to a spaceflight food system, time-delayed communications, mission-relevant timelines, contingency situations and other resource restrictions.”
Since there’s no way to duplicate the red planet’s gravity , the crew won’t experience that aspect of Martian life. They’ll also remain on Earth time, counting days rather than sols — Martian days are roughly 40 minutes longer than ours. And they’ll be spared the months-long journey in what would presumably be even more cramped quarters.
NASA’s Hawaii Space Exploration Analog and Simulation, or HI-SEAS, sits 2,400 metres above sea level on the side of a dormant volcano. The space agency also runs theMeanwhile, Space advocacy group The Mars Society has an analog station in the desert in Utah and another on Devon Island in Nunavut, whose extreme latitude means it receives about the same amount of sunlight as the equatorial regions of Mars. And, like the red planet, Devon Island is cold and uninhabited.
