Zusammenfassung
Panoramic Camera (Pancam) images from Meridiani Planum reveal a low-albedo,
generally flat, and relatively rock-free surface. Within and around
impact craters and fractures, laminated outcrop rocks with higher
albedo are observed. Fine-grained materials include dark sand, bright
ferric iron-rich dust, angular rock clasts, and millimeter-size spheroidal
granules that are eroding out of the laminated rocks. Spectra of
sand, clasts, and one dark plains rock are consistent with mafic
silicates such as pyroxene and olivine. Spectra of both the spherules
and the laminated outcrop materials indicate the presence of crystalline
ferric oxides or oxyhydroxides. Atmospheric observations show a steady
decline in dust opacity during the mission. Astronomical observations
captured solar transits by Phobos and Deimos and time-lapse observations
of sunsets.
