CHECK-UP IMAGE ON-BOARD MARS ROVER CURIOSITY
The link below shows an image taken on 23 February 2013 on-board the Mars rover Curiosity. It was taken by the Mastcam camera.
This is a check-up picture, taken just after the delivery of a sample of Martian powdered rock into the SAM intrument, following drilling into the rock. It shows the sample-processor and the delivery tool.
The clarity of this image is remarkable.
