Abstract

The Mars Science Laboratory (MSL) Curiosity rover has continued to explore the lower strata of Mt. Sharp in Gale Crater. Evidence for fluvial, lacustrine, and aeolian paleoenvironments has been found by multiple instruments. Curiosity’s multispectral imaging instrument, Mast Camera (Mastcam), is able to collect reflectance data covering visible to near-infrared wavelengths from 445 nm to 1013 nm. The primary control on Mastcam multispectral variability is the presence and amount of iron oxides. However, Mastcam can still make broad interpretations regarding mineralogy and diagenesis, especially when used in tandem with other instruments. This dataset includes Mastcam spectra from 266 observations, collected from sols 2302 to 3672 in Glen Torridon, Greenheugh pediment, and the clay-sulfate transition. Geologic metadata, like the type of rock surface and its position in stratigraphy, is included with each spectrum in the database, as well as image products (decorrelation and enhanced color stretches) that aided in our analyses, and context images that show where the spectra were extracted from.
