$Pale zones called ‘halos’ border bedrock fractures visible in this 2015 image (colorized) from the Curiosity rover. Measurements overlaid on the image offer a sense of scale for the size of these fractures. The rover team determined that the halos are rich in silica, a clue to the duration of wet environmental conditions long ago. Image credit: NASA / JPL-Caltech.$

Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 1,550 miles (2,500 km) from the surface of the planet. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene shows the entire Valles Marineris canyon system, over 1,240 miles (2,000 km) long and up to 5 miles (8 km) deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 15.5 miles (25 km) high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.

This view of a Martian rock slab called ‘Old Soaker,’ which has a network of cracks that may have originated in drying mud, comes from the Mast Camera on NASA’s Curiosity Mars rover. The location is within an exposure of Murray formation mudstone on lower Mount Sharp inside Gale Crater. Mud cracks would be evidence of a time more than 3 billion years ago when dry intervals interrupted wetter periods that supported lakes in the area. Several images from Mast Camera’s left-eye camera are combined into this mosaic view. They were taken on Dec. 20, 2016, during the 1,555th sol of Curiosity’s work on Mars. The Old Soaker slab is about 4 feet (1.2 m) long. Image credit: NASA / JPL-Caltech / MSSS.

This low-angle self-portrait of NASA’s Curiosity rover shows the vehicle at the site from which it reached down to drill into a rock target called ‘Buckskin’ on lower Mount Sharp. The selfie combines several component images taken by Curiosity’s Mars Hand Lens Imager (MAHLI) on Aug. 5, 2015, during 1065 Sol (Martian day) of the rover’s work on Mars. For scale, the rover’s wheels are 20 inches (50 cm) in diameter and about 16 inches (40 cm) wide. Image credit: NASA / JPL-Caltech / MSSS.

Color composite of Phobos taken with TGO’s CaSSIS camera on November 26, 2016. The observation was made at a distance of 4,785 miles (7,700 km). To create the final color image, two images were taken through each of the four color filters of the camera -- panchromatic, blue-green, red and infrared -- and then stitched together and combined to produce the high-resolution composite. Two of the color filters used by CaSSIS lie outside the wavelength response of the human eye, so this is not a ‘true’ color image. However, showing the data as a color representation can reveal details of the surface mineralogy. Different colors are clearly seen, with the bluest part in the direction of the large crater Stickney, which is out of view over the limb to the left. Although the exact composition of the material is unknown, the color differences are thought to be caused by compositional variations on scales of hundreds of feet to several miles.
