HiRISE: Kasei Valles
Kasei Valles is a valley system was likely carved by some combination of flowing water and lava. In some areas, erosion formed cliffs along the flow path resulting in water or lava falls. The flowing liquid is gone but the … Continue reading

HRSC: Flash floods in Mangala Valles
Catastrophic flooding triggered by ice melting from the heat of volcanic activity is thought to be responsible for the chaotic scenery depicted in this region of the Mangala Valles channel network. The images were taken by the high-resolution stereo camera … Continue reading

THEMIS: Mawrth Vallis – false color
THEMIS Image of the Day, September 29, 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

THEMIS: Mangala Valles
THEMIS Image of the Day, September 25, 2015. This VIS image shows part of the complex channel called Mengala Valles. The tear-drop shaped regions in the channel are called streamlined islands and the narrow “tail” points down stream. More THEMIS … Continue reading

Outflow channels: How did source aquifers form, why did they drain so rapidly?
Gigantic groundwater outbursts created the largest flood channels in the solar system on Mars, 3.2 billion years ago. For many years it was thought that this was caused by the release of water from a global water table, but research … Continue reading
THEMIS: Ares Vallis – false color

Groundwater outflow in experiments and on Mars
Planetary Geomorphology Image of the Month, September 2, 2015: Wouter Marra (Universiteit Utrecht, Netherlands). There are many water-worn features on the planet Mars, which contribute to the reconstruction of former hydrological conditions. For example, dendritic valley networks show that there … Continue reading
HiRISE: At the head of a Kasei Valles cataract
On Earth, cataracts represent regions where a river’s gradient increases enough to create so much turbulence, that air gets incorporated into the water body forming a bubbly current sometimes called “whitewater”. This image covers a location that may have acted … Continue reading

HiRISE: Lowest point of Osuga Valles
Osuga Valles lies around 170 kilometers to the south of Eos Chasma, which is at the eastern end of the vast Valles Marineris canyon system. This is an outflow area, probably the result of ancient and catastrophic flooding. This image … Continue reading
