Summary: Understanding human social behaviour under conditions of remote isolation, close quarters, and constrained resources will one day be critical to successfully executing a crewed mission to Mars. Analogues and simulations provide a useful tool to learn these tactics. HI-SEAS IV (Hawaii Space Exploration Analogue and Simulation) is one such experiment, and six crewmembers recently exited after an entire year in a dome on the slopes of a Hawaiian volcano. We spoke with all six members of the crew and learned a lot of valuable lessons, not least of which is the power of the human spirit and ability to make anything possible.
