Rock Characteristics (2/2)
The surface near the rover's egress from the lander contains mainly bright red drift (#1), dark gray rocks such as Cradle (#3), soil intermediate in color to the rocks and drift (#2), and dark red soil on and around the rock Lamb (#4). Globally, Mars is characterized by similar color variations. The spectra, measured using the full 13- color capability of IMP, provide evidence for the mineralogy of the unweathered rocks and highly weathered red soils.
