Expeditions were planned to numerous locations across the Martian north polar cap, including the Chasma Boreale and the polar layered terrains. The study involved wide-ranging investigations of the scientific priorities for a human presence at the Martian polar ice caps through to detailed architectural and design studies for the station. Studies were undertaken on mobility and communications and psycho-social issues for long-term operation at the Martian polar station.
