The scientists are housed in a dome on Mauna Loa and can go outside only in spacesuits,
the Hawaii Tribune-Herald reported.
They manage limited resources while conducting research and working to avoid personal conflicts. Communication is delayed by 20 minutes, the length it would take to relay messages from
Mars.
Kim Binsted, principal investigator for the
Hawaii Space Exploration Analog and Simulation (Hi-Seas), said this simulation was the second-longest of its kind after a mission that lasted 520 days in Russia.
“They’re doing OK, as far as we can tell,” Binsted said of the scientists.
