Context image The windstreak at the top of this VIS image is located on the Tharsis volcanic flows east of Arsia Mons. Windstreaks form downwind of craters and other topographic highs. Surface winds are deflected by the crater rim into chaotic flow over and around the crater, both removing and depositing dust and sand. […]

Context image Today’s VIS image shows a portion of Sirenum Fossae. The linear features 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

Context image Located between the lava plains of Daedalia Planum and Solis Planum, Claritas Fossae is a graben-filled highland. Graben are formed by tectonic activity, where extensional forces stretch the surface allowing blocks of material to slide down between paired faults. These linear grabens are termed fossae. This region of Mars had very active

Context image Today’s VIS image shows part of Gale Crater, including the large layered deposit on the crater floor. This deposit has been heavily eroded, which exposed the layering. The Curiosity Rover is located in Gale Crater. Gale crater is 150km (90 miles) in diameter. Orbit Number: 92243 Latitude: -4.91547 Longitude: 137.678 Instrument: VIS

Context image This VIS image shows part of Gorgonum Chaos. Chaos terrain is typified by regions of blocky, often steep sided, mesas interspersed with deep valleys. With time and erosion the valleys widen and the mesas become smaller. Chaotic regions form when groundwater escapes to the surface, undermining it and causing the ground to

Context image Today’s VIS image shows the complete length of two channels in northern Terra Sirenum. As with all channels in this region – including Mangala Valles – the flow is northward into the low elevation region south of Amazonis Mensa. Abus Vallis is on the left and is 66 km long (41 miles).
