Homestake

A mineral vein named “Homestake” is captured by the panoramic camera (Pancam) on NASA’s Mars Exploration Rover Opportunity. The vein is about the width of a thumb and about 18 inches (45 centimetres) long. Opportunity found it to be rich in calcium and sulphur, possibly the calcium-sulphate mineral gypsum. Homestake is near the edge of the “Cape York” segment of the western rim of Endeavour Crater. Gypsum – commonly known as plaster of Paris – typically forms from water flowing through rock.
