The network of cracks in this Martian rock slab called "Old Soaker" may have formed from the drying of a mud layer more than 3 billion years ago. The view spans about 4 feet (1.2 meters) left-to-right and combines three images taken by the Mars Hand Lens Imager (MAHLI) camera on the arm of NASA's Curiosity Mars rover.

This view from the Navigation Camera (Navcam) on the mast of NASA's Curiosity Mars rover shows rocky ground within view while the rover was working at an intended drilling site called "Precipice" on lower Mount Sharp. The right-eye camera of the stereo Navcam took this image on Dec. 2, 2016, during the 1,537th Martian day, or sol, of Curiosity's work on Mars. On the previous sol, an attempt to collect a rock-powder sample with the rover's drill ended before drilling began. This led to several days of diagnostic work while the rover remained in place, during which it continued to use cameras and a spectrometer on its mast, plus environmental monitoring instruments. In this view, hardware visible at lower right includes the sundial-theme calibration target for Curiosity's Mast Camera. Image credit: NASA/JPL-Caltech
