If humans were to inhabit Mars, how would we do it? What would we need to know? How would we breathe, eat, sleep, communicate, interact and live? University of Toronto geology graduate student Darlene Lim is among a team of scientists on the Haughton Mars Project asking, and answering, those very questions. This project, led by the National Aeronautics and Space Administration, will be conducted on Haughton Crater on Devon Island in the Canadian high Arctic.
