Today's VIS image shows a section of Cerberus Fossae. Cerberus Fossae are located in Elysium Planitia, southeast of the Elysium Mons volcanic complex. The linear features in the image are tectonic graben. Graben are formed by extension of the crust and faulting. When large amounts of pressure or tension are applied to rocks on timescales that are fast enough that the rock cannot respond by deforming, the rock breaks along faults. In the case of a graben, two parallel faults are formed by extension of the crust and the rock in between the faults drops downward into the space created by the extension. Numerous sets of graben are visible in this THEMIS image, trending from north-northwest to south-southeast. Because the faults defining the graben are formed perpendicular to the direction of the applied stress, we know that extensional forces were pulling the crust apart in the east-northeast/west-southwest direction. The Cerberus Fossae graben are sources of both channels and significant volcanic flows. Cerberus Fossae cuts across features such as hills, indicating the relative youth of the tectonic activity. The Cerberus Fossae system is 1235km (767 miles) long.

Visible in this observation from NASA Mars Reconnaissance Orbiter is a section of Cerberus Fossae, which are comprised of a series of rifts present located in Elysium Planitia just north the Martian equator.

Today's VIS image shows a section of Cerberus Fossae. Located southeast of the Elysium Planitia volcanic complex, the linear graben in the image were created by tectonic forces related to the volcanic activity. The graben are sources of both channels and significant volcanic flows. The Cerberus Fossae graben cut across features such as hills, indicating the relative youth of the tectonic activity. Graben form where extensional tectonic forces allows blocks of material to subside between paired faults. Cerberus Fossae are 270km (168 miles) long. Just off the image to the right is the start of Athabasca Valles, which is seen flowing below the graben to the bottom left of the image. Arising from Cerberus Fossae, the formation mode of this channel is still being debated. While the channel features are similar to water flow, other features are similar to lava flows, and yet other features have an appearance of slabs of material that floated on an underlying fluid. It is thought that Athabasca Valles is the youngest outflow channel system on Mars. Athabasca Valles is just one of the complex channel formations in the Elysium Planitia region. The THEMIS VIS camera is capable of capturing color images of the Martian surface using five different color filters. In this mode of operation, the spatial resolution and coverage of the image must be reduced to accommodate the additional data volume produced from using multiple filters. To make a color image, three of the five filter images (each in grayscale) are selected. Each is contrast enhanced and then converted to a red, green, or blue intensity image. These three images are then combined to produce a full color, single image. Because the THEMIS color filters don't span the full range of colors seen by the human eye, a color THEMIS image does not represent true color. Also, because each single-filter image is contrast enhanced before inclusion in the three-color image, the apparent color variation of the scene is exaggerated. Nevertheless, the color variation that does appear is representative of some change in color, however subtle, in the actual scene. Note that the long edges of THEMIS color images typically contain color artifacts that do not represent surface variation.

Cerberus, seen in this image from NASA Mars Odyssey spacecraft, is a dark region on Mars that has shrunk down from a continuous length of about 1000 km to roughly three discontinuous spots a few 100 kms in length in less than 20 years.

Geological faulting has opened cracks in the Cerberus region that slice through flat plains and mesas alike. This image is part of an All Star set marking the occasion of NASA Mars Odyssey as the longest-working Mars spacecraft in history.

This image taken by NASA Mars Reconnaissance Orbiter shows part of Cerberus Fossae, a long system of extensional normal faults arranged in trough-bounding graben-bounding pairs.

Cerberus Fossae is a steep-sided set of troughs cutting volcanic plains to the east of Elysium Mons. Steep slopes on Mars have active landslides (also called "mass wasting"), and here we see evidence for two types of activity. First, the light bluish boulders on the slope appear to originate at a layer of bedrock (also light blue) near the top of the section. Second, the dark thin lines are recurring slope lineae, probably also due to mass wasting, but composed of finer-grained materials. https://photojournal.jpl.nasa.gov/catalog/PIA23182

A dominant driver of surface processes on Mars today is aeolian (wind) activity. In many cases, sediment from this activity is trapped in low-lying areas, such as craters. Aeolian features in the form of dunes and ripples can occur in many places on Mars depending upon regional wind regimes. The Cerberus Fossae are a series of discontinuous fissures along dusty plains in the southeastern region of Elysium Planitia. This rift zone is thought to be the result of combined volcano-tectonic processes. Dark sediment has accumulated in areas along the floor of these fissures as well as inactive ripple-like aeolian bedforms known as "transverse aeolian ridges" (TAR). Viewed through HiRISE infrared color, the basaltic sand lining the fissures' floor stands out as deep blue against the light-toned dust covering the region. This, along with the linearity of the fissures and the wave-like appearance of the TAR, give the viewer an impression of a river cutting through the Martian plains. However, this river of sand does not appear to be flowing. Analyses of annual monitoring images of this region have not detected aeolian activity in the form of ripple migration thus far. http://photojournal.jpl.nasa.gov/catalog/PIA21063

This image from NASA Mars Odyssey spacecraft shows fractures within the volcanic plains south of Elysium Mons.

The trenches or fossae are found in Athabasca Valles as seen by NASA Mars Reconnaissance Orbiter. These trenches or "fossae" are about a kilometer (0.62 miles) across. This area shows where two segments have joined up and are close to a third section. The fossae are probably areas where the surface has collapsed down into voids made from faults (huge cracks with movement on either side) that don't extend up to the surface. In structural geology, when multiple faults are closely spaced, we call that a relay zone. These zones have much higher stress built up in the crust and consequently tend to be more fractured. These fractures can serve as "pipes" for fluids (water, lava, gases) to flow through. This area corresponds with the youngest of Mars' giant outflow channels, Athabasca Valles, that is only 2 to 20 million years old and shows geologic evidence of having been formed and modified jointly by water and lava. http://photojournal.jpl.nasa.gov/catalog/PIA19300

NASA's Mars Reconnaissance Orbiter used its High-Resolution Imaging Science Experiment (HiRISE) camera to capture this impact crater in Cerberus Fossae, a seismically active region of the Red Planet, on March 4, 2021. Scientists matched the crater's appearance on the surface with a quake detected by NASA's InSight lander, which was about 1,000 miles (1,640 kilometers) away. The crater is estimated to be about 71 feet (21.5 meters) in diameter. Most of the impacts detected by InSight, which was retired in 2022 after operating for more than four years, were thought to send their seismic signals through the Martian crust. But scientists concluded the energy from this impact traveled through the planet's mantle, much deeper than expected, after studying the location of the impact crater and seismic signals linked to it. Because of this finding, models of the composition and structure of the inner planet will have to be reassessed. This impact crater, along with others covered in a pair of papers published in Geophysical Research Letters in February 2025, was found with help from a machine learning algorithm developed at NASA's Jet Propulsion Laboratory in Southern California. The algorithm searched through tens of thousands of images captured by MRO's Context Camera in a matter of days, detecting 123 potential craters that may have occurred at the same time InSight was recording data. Traditional methods, in which human scientists carefully peer over images pixel by pixel, would have taken years of work to find these matches. Human scientists still had to narrow down the pool of candidate craters to 49 that matched InSight's quake data. After discovering this impact, scientists commanding MRO to take more detailed imagery with HiRISE. https://photojournal.jpl.nasa.gov/catalog/PIA26518

This image captured by NASA Mars Reconnaissance Orbiter shows a small channel cutting into young volcanic lavas in a region where massive catastrophic flooding took place in the relatively recent past. The Athabasca Valles region includes a vast lava flow, thought to be the youngest on Mars, with even younger outflow channels that were carved by running water. The source of the water is believed to be the Cerberus Fossae valleys to the north, which may have penetrated to an over-pressurized aquifer in the subsurface. Nowadays, erosion by gravity, wind, and frost gradually wears down the rims of the outflow channels. In this scene, we see dark materials along the channel rim that were probably exposed by this erosion. The dark materials are less red than the surrounding surface and so they appear blue in this enhanced color picture. Viewed close up, the dark materials show ripples that suggest they are made up of mobile sand. It is possible that this sand originated elsewhere and simply collected where we see it today, but the fact that sand is not found elsewhere in the scene suggest to us that it is eroding out of the volcanic layers at the retreating rim of the channel. Sand sources are important because mobile sand grains have only a limited lifetime, wearing down and chipping apart each time they impact the surface. Erosion of the volcanic materials in this region may provide sands to replace those that are destroyed. Few such sand sources have so far been identified on Mars. http://photojournal.jpl.nasa.gov/catalog/PIA18889
