Gravel on Curiosity Rover?

Question

I was looking at a visually impressive Panoramic 360 video derived from photographs taken by Curiosity Rover.

I noticed something curious, what looks like small pieces of gravel scattered across the back of the rover:

Is that debris flicked or blown onto the rover during the landing?

Answer 1

Yes, Curiosity got showered with gravel and sand as the skycrane flew away. One of the wind sensors was broken in the process: https://www.bbc.com/news/science-environment-19338870
