At “Mars on Earth,” Planning a Manned Mission National Geographic

To scientists, Canada’s rocky, windblown Devon Island, 10 degrees above the Arctic Circle with an average temperature of 1.4 degrees Fahrenheit (-17 degrees Celsius), is “Mars on Earth.” What better place, then, to serve as NASA’s lab for a possible manned mission to the Red Planet? Devon Island even boasts the Mars-like 14-mile-wide (23-kilometer-wide) Haughton crater, for which the NASA Haughton-Mars Project was named.
