The Japanese Hayabusa 2 twitter account reports that the spacecraft has begun descending toward Ryugu in preparation to deploy the MASCOT lander. Nothing on the English twitter as of the time of this post.

It's easy to make dust through micrometeorite impacts, and some at least should be retained. But cementing or consolidating it is much more difficult. More likely it's a sifting effect, where jostling by impacts causes large chunks to rise and small objects to fall into spaces between them. On Itokawa the same thing was seen except that in some low-lying areas the fine materal became concentrated in smooth patches. We don't see that here, maybe because Ryugu is more equidimensional.
