From NPR:
The University of Hawaii runs an experiment funded by NASA entitled HI-SEAS. In HI-SEAS, 6 people live in a habitat designed to simulate a mission on Mars for 8 months. Jay, a visiting scholar in our lab, is one of the six who will be living in the Mars simulation dome atop a volcano in Hawaii for the next 8 months.
