NASA's Haughton Mars Project (HMP) is part of an international interdisciplinary field research facility located on the world's largest uninhabited island, Devon Island. This project uses the polar desert setting and harsh climate of the Canadian High Arctic to mimic the environmental conditions that crewmembers are likely to encounter on Mars and other planets.
Devon Island's barren terrain, freezing temperatures, isolation, and remoteness offer NASA scientists and personnel a number of unique research opportunities. Other factors, such as the Arctic day and night cycle and restricted logistics and communications capabilities, offer fitting analogs for the challenges that crewmembers will likely face on long-duration space flights.
In addition to ongoing studies that focus on variables such as communications, equipment testing, and vehicular and extra-vehicular operations, Devon Island is also the site of the Exploration program, which aims to develop new technologies, strategies, and operational protocols geared to support the future exploration of the Moon, Mars, and other planets.
