Abstract

The precise location and relative elevation of Spirit during its traverses from the Columbia Memorial station to Bonneville crater were determined with bundle-adjusted retrievals from rover wheel turns, suspension and tilt angles, and overlapping images. Physical properties experiments show a decrease of 0.2% per Mars solar day in solar cell output resulting from deposition of airborne dust, cohesive soil-like deposits in plains and hollows, bright and dark rock coatings, and relatively weak volcanic rocks of basaltic composition. Volcanic, impact, aeolian, and water-related processes produced the encountered landforms and materials.

1. A martian solar day has a mean period of 24 hours 39 min 35.244 s and is referred to as a sol to distinguish this from a roughly 3% shorter solar day on Earth. A martian sidereal day as measured with respect to the fixed stars is 24 hours 37 min 22.663 s as compared with 23 hours 56 min 04.0905 s for Earth. See www.giss.nasa.gov/tools/mars24 for more information.

2. Names have been assigned to areographic features by the Mars Exploration Rover (MER) team for planning and operations purposes. The names are not formally recognized by the IAU.

4. The term martian soil is used here to denote any loose unconsolidated materials that can be distinguished from rocks bedrock or strongly cohesive sediments. No implication of the presence or absence of organic materials or living matter is intended.
