MARS RECONNAISSANCE ORBITER HIRISE IMAGES
September 18, 2013
o Sinuous Ridge Cutting Across Geologic Units of the Medusae Fossae Formation
At this location is an exceptionally long sinuous ridge, possibly an inverted fluvial feature.
o Martian Glaciers and Brain Terrain
This strange-looking surface might be related to flow of the ice, but we still don't have an definite explanation for this mystery.
o Two Generations of Windblown Sediments
This colorful scene is situated in the Noctis Labyrinthus, perched high on the Tharsis rise in the upper reaches of the Valles Marineris canyon system.
All of the HiRISE images are archived here:
