Overview photo showing the HMP Research Station and surrounding area at the time the study was conducted (Summer, 2002). The tent area in the foreground served as personal living quarters for HMP field participants. Immediately behind is the central base camp, consisting of core facilities, laboratory space, communications and mess tent, etc. The prototype Mars greenhouse is located to the left of the core facility. The rim of the impact crater is distant-right. The FMARS habitat, located on the crater rim, was not used in this study.
