The Mars Exploration Rover Spirit and its Athena science payload have been used to investigate a landing site in Gusev crater. Gusev is hypothesized to be the site of a former lake, but no clear evidence for lacustrine sedimentation has been found to date. Instead, the dominant lithology is basalt, and the dominant geologic processes are impact events and eolian transport. Many rocks exhibit coatings and other characteristics that may be evidence for minor aqueous alteration. Any lacustrine… 

Surficial Deposits at Gusev Crater Along Spirit Rover Traverses

The Mars Exploration Rover Spirit has traversed a fairly flat, rock-strewn terrain whose surface is shaped primarily by impact events, although some of the landscape has been altered by eolian

The Opportunity Rover's Athena Science Investigation at Meridiani Planum, Mars

The Mars Exploration Rover Opportunity has investigated the landing site in Eagle crater and the nearby plains within Meridiani Planum, and the rocks are interpreted to be a mixture of chemical and siliciclastic sediments formed by episodic inundation by shallow surface water, followed by evaporation, exposure, and desiccation.

Basaltic rocks analyzed by the Spirit Rover in Gusev Crater.

Chemical analyses of rocks by the Alpha Particle X-ray Spectrometer are consistent with picritic basalts, containing normative olivine, pyroxenes, plagioclase, and accessory FeTi oxides, which extend the known range of rock compositions composing the martian crust.

Wind-Related Processes Detected by the Spirit Rover at Gusev Crater, Mars

Characteristics of some rocks, such as a two-toned appearance, suggest that they were possibly buried and exhumed on the order of 5 to 60 centimeters by wind deflation, depending on location.

Water alteration of rocks and soils on Mars at the Spirit rover site in Gusev crater

Investigation of soils, rock coatings and rock interiors by the Spirit rover from sol (martian day) 1 to sol 156 provides evidence for limited but unequivocal interaction between water and volcanic rocks of the Gusev plains.

Fluid lava flows in Gusev crater, Mars

[1] Rocks on the floor of Gusev crater are basaltic in composition, as determined from measurements by the Mars Exploration Rover, Spirit. On the basis of compositional data, models of the basaltic

Overview of the Spirit Mars Exploration Rover Mission to Gusev Crater: Landing site to Backstay Rock in the Columbia Hills

Spirit landed on the floor of Gusev Crater and conducted initial operations on soil-covered, rock-strewn cratered plains underlain by olivine-bearing basalts. Plains surface rocks are covered by

Mars Exploration Rover Geologic traverse by the Spirit rover in the Plains of Gusev Crater, Mars

The Spirit rover completed a 2.5 km traverse across gently sloping plains on the floor of Gusev crater from its location on the outer rim of Bonneville crater to the lower slopes of the Columbia

Mars Exploration Rover surface operations: driving spirit at Gusev Crater

Spirit has achieved increases in efficiency, accuracy, and traverse capability through increasingly complex command sequences, growing experience, and updates to the on-board and ground-based software.

Localization and Physical Properties Experiments Conducted by Spirit at Gusev Crater

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.

The alpha particle x-ray spectrometer on the Spirit rover determined major and minor elements of soils and rocks in Gusev crater in order to unravel the crustal evolution of planet Mars. The

Textures of the soils and rocks at Gusev Crater from Spirit's Microscopic Imager.

The Microscopic Imager on the Spirit rover analyzed the textures of the soil and rocks at Gusev crater on Mars at a resolution of 100 micrometers, finding rock textures consistent with a volcanic origin and subsequent alteration and/or weathering by impact events, wind, and possibly water.

Initial Results from the Mini-TES Experiment in Gusev Crater from the Spirit Rover

The Miniature Thermal Emission Spectrometer on Spirit has studied the mineralogy and thermophysical properties at Gusev crater and two spectrally distinct coatings are observed on rocks, a possible indicator of the interaction of water, rock, and airfall dust.
