The young Mars would have had enough water to cover its entire surface in a liquid layer about 140 m deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 km.

NASA’s Mars rover Curiosity has captured its highest-resolution panorama (high-resolution file, 2.43 GB) yet of the Martian surface. The new panorama...

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

NASA’s Curiosity Rover Finds Mineral Hematite on Mars

Using the High Resolution Imaging Science Experiment (HiRISE) camera — the most powerful camera ever to orbit another planet, NASA’s Mars Reconnaissance...

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