A crop from a 9-tile NavCam image shows the latest sample hole drilled in the surface of Mars. The drilled hole has an approximate diameter of 1 inch (2.5 cm). A rock core appears in several Bayer encoded raw images from the MastCam-Z camera. I’ll post the color processed versions when they become available. Credits: NASA/JPL-Caltech
Dropping a bit is one of the options they had, but there appears to be a little wear on some of the coring bits, so I assume that dropping a bit is probably not their preferred option after such an event. Hoping to see a mission update as to why the drilling operation was stalled, it could be as simple as a small movement on one of the wheels was detected.
