Wonder what material that greyish rock looking stuff on the surface is.

I went poking around Wikpedia. Ryugu's surface is mostly carbon. It's also a "rubble pile" and about 50% of its volume is empty space. There could even be large voids within because the force of friction between pieces is greater than the force of gravity holding it together.

Here's what it looks like when shot at with a "bullet"[0].
