HiRISE: Strata always have a story
Strata always have a story. This area is located within the massive Valles Marineris canyon system, and was suggested to monitor for recurring slope lineae on a slope to the south, but we thought the gorgeous bedrock deserved to be … Continue reading

Many bedrock plains are clastic rocks, not lavas
The Martian surface is dominated by loose dust, sands, and rocks, but high spatial resolution imaging has permitted the detection of numerous flat-lying exposures of ancient, intact bedrock. These “bedrock plains” have previously been interpreted as lava sequences, perhaps similar … Continue reading

HiRISE: Wrinkles in rock
The bedrock in this region of Arabia Terra has been worn away by the wind, revealing their internal structure and geologic history. The wavy lines are individual layers of sand and dust, originally laid down as the bedrock was forming. … Continue reading

HiRISE: Geologic history revealed in Valles Marineris
An enhanced-color image reveals bedrock that is several kilometers below the top of the giant Valles Marineris canyons. The upper layers have relatively little diversity of colors and textures, but deeper levels show more complex processes. The upper layers could … Continue reading

HiRISE: Ejecta and possible bedrock on a crater floor in Aonia Terra
Ejecta and possible bedrock on a crater floor in Aonia Terra. This is just to the east of an impact crater that is almost dead center within a much larger impact crater. (249 km above the surface; black and white … Continue reading

HiRISE: Horse playing the flute
Horse playing the flute. Maybe you can see a horse playing a flute here, but really this is a portion of the floor of Eberswalde Crater, at one time candidate landing site for the Mars Science Laboratory. The light-toned bedrock … Continue reading

HiRISE: Mars and the amazing Technicolor ejecta blanket
A close-up image shows the exposed bedrock of an ejecta blanket of an unnamed crater in the Mare Serpentis region of Mars. Ejecta, when exposed, are truly an eye-opening feature, as they reveal the sometimes exotic subsurface, and materials created … Continue reading

HiRISE: Dragon scales of Mars
This intriguing surface texture is the result of rock interacting with water. The rock was then eroded and later exposed to the surface. The pinkish, almost dragon-like scaled texture represents Martian bedrock that has specifically altered into a clay-bearing rock. … Continue reading
