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 of the surface not easily identified in a single band image. Today's false color image shows part of Iani Chaos.

This image captured by NASA 2001 Mars Odyssey shows a portion of Iani Chaos.

Today's VIS image shows part of Iani Chaos. Chaos terrain is typified by mesas and valleys. The initial breakup of the land is due to tectonic forces. With time and erosion the valleys widen and the mesas grow smaller. This image shows a cross section of Iani Chaos and the different scales of the mesas are readily visible.

Iani Chaos - Another View In False Color

Several different surface textures are present on the lower elevations of Iani Chaos in this image from NASA 2001 Mars Odyssey spacecraft.

This image captured by NASA 2001 Mars Odyssey spacecraft shows a small portion of Iani Chaos. The brighter floor material is being covered by sand, probably eroded from the mesas of the Chaos.

Today's VIS image shows part of Iani Chaos. Chaos terrain is typified by mesas and valleys. The initial breakup of the land is due to tectonic forces. With time and erosion the valleys widen and the mesas grow smaller. Layers of material are visible at the bottom of the image, the source of the material is likely the erosion of the nearby mesas.

This VIS image captured by NASA 2001 Mars Odyssey spacecraft of Iani Chaos shows the layered deposit that occurs on the floor. It appears that the layers were deposited after the chaos was formed. Image information: VIS instrument. Latitude 2.3S, Longitude 342.3E. 17 meter/pixel resolution. http://photojournal.jpl.nasa.gov/catalog/PIA03200

The channel-like features in image captured by NASA 2001 Mars Odyssey spacecraft are fracture sets related to the formation of Iani Chaos, which occurs directly north of the image.

This anaglyph from NASA Mars Global Surveyor shows eroded, pitted, light-toned layer outcrops in Iani Chaos. 3D glasses are necessary to view this image.

This channel is located south of Iani Chaos

The THEMIS 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 of the surface not easily identified in a single band image. Today's false color image shows part of Iani Chaos. The "dark blue" material is likely basaltic sand.

These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today's false color image shows Iani Chaos. The material appearing as dark blue is likely sand that has been caught in the surface furrows.

This image captured by NASA 2001 Mars Odyssey spacecraft shows where Ares Vallis starts top of image from Iani Chaos bottom of image.

Today's VIS image shows a section of Ares Vallis. Ares Vallis is a large channel that arises in Iani Chaos, passes through Margaritifer Terra, and then empties into Chryse Planitia.

The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. This image from NASA 2001 Mars Odyssey spacecraft shows the beginning of Ares Vallis at the edge of Iani Chaos.

This image shows a small landslide in Iani Chaos. Landslides are common on Mars where there are steep slopes, including this area where there are numerous mounds and hills. What is unusual about this landslide is that it carved a path downslope as it moved, similar to a snow plow pushing away snow as it moves forward. This image is part of a stereo pair so that scientists will examine the landslide in 3D to understand its formation mechanism. https://photojournal.jpl.nasa.gov/catalog/PIA23232
