Understanding the geology of a region from a robotic platform can be a challenging and difficult task. In order to prepare the team of investigators and engineers for the upcoming 2003 Mars Exploration Rover (MER) Mission, a "blind" rover field test was performed August 10 - 19, 2002, using the Field Integrated Design and Operations (FIDO) Rover. The field site, which is located near Gray Mountain Arizona (approximately 40 miles north of Flagstaff), was chosen because it: (1) maximizes science return and permits rover trafficability, (2) is easily accessed via a well-maintained mining road, (3) occurs north of Flagstaff, Arizona, where seasonal temperatures are adequate for rover operations and climate records show minimal rainfall, (4) lacks vegetation (a very difficult variable for Earth), and (5) contains diverse geological terrains similar to what might be encountered on Mars, including claystones, siltsones, mudstones, and sandstones of the Shinarump Member of the Chinle Formation. that crop out among fluvially carved drainages, fluvial and eolian deposits that partly blanket the drainage floors, and cobbles and boulders of diverse petrology and geochemistry (e.g., basalt, chert, sandstone, limestone, metamorphic). The goal of the FIDO test was to teach the MER Science Team the techniques involved in conducting a geologic investigation with a remote rover. Inherent disadvantages associated with remote robotic exploration include a limited time-associated visibility to the site. This disadvantage is somewhat offset by the availability of instruments on the rover that might ordinarily be available to a geologist only in a laboratory setting. This talk will further explore the coupling of a remote robotic platform with what is known about the field site to provide insight into future robotic exploration of planetary locales.
