The pits visible here aren't impact craters. The material they're embedded into is ejecta (stuff thrown out of an impact crater when it forms) from a large crater called Hale which is not seen in this image.
Substances called "volatiles" -- which can explode as gases when they're quickly warmed by the immense heat of an impact-exploded out of the ejecta and caused these pits. Unrelated sand dunes near the top of the image have since blown over portions of the pits.
