Exiles on 'Mars': Doc on Hawaiian Mock Mission Seeks Funds

The answer is many astronauts, as well as one plucky crew simulating a Mars mission in Hawaii. The HI-SEAS program (Hawaii Space Exploration Analog and Simulation) is examining how humans would live, work and play on Mars or another space-based location. The most recent HI-SEAS crew spent a year in an isolated habitat on Mauna Loa in Hawaii, to simulate ;what living conditions might be like for a crew of real Mars astronauts.
