Figure A NASA’s Curiosity Mars rover captured this image of rhythmic rock layers with a repetitive pattern in their spacing and thickness. The pattern might have been caused by weather or climate cycles occurring while the sediment layers were being deposited, such as dust storms happening at regular intervals in the ancient past. This […]

Figure A NASA’s Curiosity Mars rover used its Mastcam to capture this mosaic of Gediz Vallis on Nov. 7, 2022, the 3,646th Martian day, or sol, of the mission. In the center of the valley in this image is a pile of boulders and debris that may have been swept there by flowing water

Figure A Figure B Click on images for larger versions NASA’s Curiosity Mars rover used its Mastcam to capture this 360-degree panorama of “Marker Band Valley” on Dec. 16, 2022, the 3,684th Martian day, or sol, of the mission. The rover sits in the center of the image; below its raised robotic arm is

Figure A NASA’s Curiosity Mars rover used its ChemCam instrument to view boulders on Gediz Vallis Ridge Nov. 15 to 17, 2022, the 3,653rd to 3,655th Martian days, or sols, of the mission. These boulders are thought to have been washed down in a debris flows in the ancient past and are probably some

Context image This VIS image shows a cross section of the upper elevations of Pavonis Mons, including part of the summit caldera (circular region near the center of the image). Pavonis Mons is the central volcano of the three large Tharsis volcanoes. In order from north to south the volcanoes are Ascreaus Mons, Pavonis

Context image Today’s VIS image shows part of the eastern end of Tithonium Chasma. Tithonium Chasma is at the western end of Valles Marineris. Valles Marineris is over 4000 kilometers long, almost as wide as the United States. Tithonium Chasma is almost 810 kilometers long (499 miles), 50 kilometers wide and over 6 kilometers

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
