Description
This image from the Mars Exploration Rover Opportunity's front hazard-avoidance camera focuses on a target called "Goal 5." Goal 5, examined during the "Eagle Crater" soil survey, is a wind-rippled spot on the upper part of the crater, which the miniature thermal emission spectrometer shows is higher in hematite content compared to other soils within the crater. The light soil in the center of the image is referred to as "Lanikai" -- an inspiration from the white sand beaches of Hawaii. The dark soil is referred to as "Punaluu" after the black sand Hawaiian beaches.
