Six NASA-backed research subjects who have been living in a Mars-like habitat on a remote Hawaii volcano since January have emerged from isolation.
After eating mostly freeze-dried food, they feasted on Sunday on fresh-picked tropical fruit, vegetables and a fluffy egg strata.
The four men and two women are part of a study designed to better understand the psychological impacts of long-term space travel on astronauts.
The data they produced will help NASA select individuals and groups with the right mix of traits to best cope with the stress, isolation and danger of a two-to-three year trip to Mars.
The US space agency hopes to send humans to the red planet by the 2030s.
