"Notos" probably comes from "notios" ("moist", a reference to the warm rains and storms brought from the south). "Eurus" and
Project Boreas rovers or from the station. The design study investigated communications for Pole Station and satellite requirements for sustaining base to field communications. The unique psycho-social issues associated with the long and permanently dark Martian polar winter were addressed. Medical requirements for long-term operation at the Martian polar ice caps were investigated in addition to the nutrition requirements, which were used to constrain the life support system design. The Project Boreas report was shortlisted for the 2007 Sir Arthur Clarke Award in the category of "Best Written Presentation". Project Boreas Project Boreas was a study conducted between 2003 and 2006 by
