HiRISE: Light-toned layers in Tithonium Chasma
Tithonium Chasma is a part of Valles Marineris, the largest canyon in the Solar System. If Valles Marineris was located on Earth, at more than 4,000 kilometers long and 200 kilometers wide, it would span across almost the entire United … Continue reading

THEMIS: Candor Chasma – false color
THEMIS Image of the Day, August 11, 2015. The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations … Continue reading

Valleys, deltas, and lacustrine sediment in the southwestern Melas Basin, Valles Marineris
Planetary Geomorphology Image of the Month, July 30, 2015: Joel Davis (University College, London, UK). During the last few decades, dry river valley networks and delta fan structures have been found to be increasingly common on ancient terrains on the … Continue reading

HiRISE: Diverse deposits in Melas Chasma
This scene includes chaotic deposits with a wide range of colors. The deposits are distinctive with both unique colors and small-scale textures such as fracture patterns. These are probably sedimentary rocks, transported and deposited in water or air. The original … Continue reading

HiRISE: Purple mountain’s majesty
This image of an isolated mountain in the Southern highlands reveals a large exposure of “purplish” bedrock. Since HiRISE color is shifted to longer wavelengths than visible color and given relative stretches, this really means that the bedrock is roughly … Continue reading

HiRISE: Sedimentary deposits within Ius Chasma
Sedimentary deposits are common within Valles Marineris. Most of the larger chasmata contain kilometer-thick light-toned layered deposits composed of sulfates. However, some of the chasmata, like Ius Chasma shown in this HiRISE image, either lack these deposits or have much … Continue reading

HiRISE: Light-toned deposit in Aureum Chaos
The objective of this observation is to examine a light-toned deposit in a region of what is called “chaotic terrain.” There are indications of layers in the image. Some shapes suggest erosion by a fluid moving north and south. The … Continue reading

HiRISE: Sedimentary rock layers on a crater floor
This image covers layered sedimentary rocks on the floor of an impact crater north of Eberswalde Crater. There may have been a lake in this crater billions of years ago, and the area was once considered a landing spot for … Continue reading
