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.

$This false-color image demonstrates how use of special filters available on Curiosity’s Mastcam camera can reveal the presence of certain minerals in target rocks. It is a composite of images taken through three ‘science’ filters chosen for making hematite stand out as exaggerated purple. Mastcam’s narrow-band filters used for this view help to increase spectral contrast, making blues bluer and reds redder, particularly with the processing used to boost contrast in each of the component images of this composite. Fine-grained hematite preferentially absorbs sunlight around in the green portion of the spectrum around 527 nm. That gives it the purple look from a combination of red and blue light reflected by the hematite and reaching the camera through the other two filters. Bright lines within the rocks are fractures filled with calcium sulfate minerals. Image credit: NASA / JPL-Caltech / MSSS.$

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

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.
