Snapshots of an ancient cover-up
Article Abstract:
Images from the Mars Orbiter Camera on the Mars Global Surveyor spacecraft have provided information on the processes that shaped the Martian surface. Malin and Carr show that images of channels suggest a groundwater source, and Thomas and colleagues have described the modification of the surface by windblown dust. Hartmann and colleagues have described sediments that fill small craters entirely and McEwen and colleagues have provided evidence for fine-scale layering in the Valles Marineris canyon.
