To simulate the experience of a crew stuck inside cramped quarters under stressful conditions, a nonprofit is planning a one-year mock Mars mission in the Arctic.

The mission, to begin in July 2014, is being planned by the Mars Society, an organization dedicated to manned exploration of the Red Planet. Six crew members will spend a full year living inside the Flashline Mars Arctic Research Station (FMARS), a 25-foot-tall (7.6 meters), 27-foot-wide (8.3 m) cylindrical habitat on Devon Island in the high-latitude Canadian Arctic.
