Abstract

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. Weakly bound agglomerates of dust are present in the soil near the Columbia Memorial Station. Some of the brushed or abraded rock surfaces show igneous textures and evidence for alteration rinds, coatings, and veins consistent with secondary mineralization. The rock textures are consistent with a volcanic origin and subsequent alteration and/or weathering by impact events, wind, and possibly water.

5. 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 it 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.
