Mc Murdo Panorama (1)

Caption NASA originale:"This beautiful scene reveals a tremendous amount of detail in Spirit's surroundings. Many dark, porous-textured volcanic rocks can be seen around the Rover, including many on Low Ridge. Two rocks to the right of center, brighter and smoother-looking in this image and more reflective in infrared observations by Spirit's Miniature Thermal Emission Spectrometer, are thought to be meteorites. On the right, "Husband Hill" on the horizon, the rippled El Dorado sand dune field near the base of that hill and lighter-toned Home Plate below the dunes provide context for Spirit's travels since mid-2005. Left of center, tracks and a trench dug by Spirit's right-front wheel, which no longer rotates, have exposed bright underlying material. This bright material is evidence of sulfur-rich salty minerals in the subsurface, which may provide clues about the watery past of this part of Gusev Crater".
