Call for Volunteers: The Mars Society is requesting volunteers to participate as members of the crew of the Mars Desert Research Station in southern Utah during extended simulations of human Mars exploration operations. The upcoming Mars Desert Research Station field season will begin in December 2004 and run through April 2005. The Mars Society will be issuing an additional call for volunteers for the summer 2005 field season of the Flashline Mars Arctic Research Station (FMARS) on Devon Island later. However those volunteering for MDRS at this time may also volunteer for FMARS 2005. FMARS crew selection is highly competitive, and prior experience at MDRS, while not strictly required, is considered to be an important credential for FMARS selection. In 2004, for example, 6 out of 7 FMARS crew members had prior MDRS experience. Submission deadline for the first round of MDRS selections is October 31, 2004. Applications submitted after that date will be considered for openings as they become available.
