Reports from the field indicate that the 2004 crew of the Flashline Mars Arctic Research Station (FMARS) is doing very well. The FMARS is located on the rim of a 20 km diameter impact crater on Canada’s Devon Island, 900 miles from the North Pole. The crew, consisting of five Americans, one Canadian, one Hungarian, and one Pole, are attempting to conduct a sustained program of field exploration of the Mars-like polar desert while functioning under Mars mission operational constraints. By so doing, they are gaining essential knowledge that will help develop the set of field tactics that human explorers will need to use on Mars.
