Life on Mars: Research group emerges from planetary isolation in Hawaiian volcano

Six people, including an Edinburgh University scientist, have emerged after after spending eight months confined in a dome simulating a mission to Mars.

The group were kept in isolation on a remote Hawaiian volcano to test how humans would react to living in confined conditions for an extended period of time.

Samuel Payler, a doctoral candidate at the UK Centre for Astrobiology at the University of Edinburgh, and five other researchers entered the HISEAS (Hawaii Space Exploration Analog and Simulation) habitat on Mauna Loa in January.
