Why is there no moon dust on the moon rocks in the photos?

Answer 1

There is loads of dust. There isn't any wind to blow it around into accumulations and into patterns like we see on sand dunes on earth. Because dust is so fine and evenly spread, it is hard to see in the photos

Answer 2

Moon rocks brought back from the Apollo missions were collected in vacuum-sealed containers, preventing moon dust from contaminating the rock samples. The absence of moon dust on the rocks in the photos is due to the careful handling and preservation techniques used during the collection process.
