Curiosity Rover Photographs 'Footprints' on Mars' Mount Sharp

For 14 years, NASA's Curiosity Rover has been investigating Mars and recently captured images of distinctive, expansive shallow pits on the bedrock of Mount Sharp. Michelle Minitti, the deputy principal investigator for Curiosity's Mars Hand Lens Imager (MAHLI), explained that these pits arise from the erosion of resistant nodules, although no clear remnants were observed. The rover's Mastcam and ChemCam obtained images, while MAHLI and Mastcam produced stereo mosaics for a digital elevation model. Minitti referred to these discoveries as a new challenge regarding the rock stratigraphy of Mount Sharp. Additionally, Curiosity identified coral-like formations and documented the Antofagasta crater, which measures 32 feet (10 meters) in diameter and features honeycomb-shaped polygons. A footprint-like image was recorded on July 24.
