A reasonable question. At least the NH CD, and I thought the Voyager
one as well but could be wrong about that, are *under* the MLI
(insulation, about 15 sheets of metallized mylar alternating with a
very loose-weave mesh).
Most dust-grain-sized stuff will vaporize on the outer layer, then
get stopped by the inner layers. There is the possibility of
something pea-sized, but there's not just a lot of particles/cubic km
out in the Kuiper Belt and Oort cloud.
