I see the requirement to avoid a collision while in safe mode, but how is burning sunward always the safest direction?
It looks like the probe might be in a polar orbit, and it may also be the case that the plane of the orbit is perpendicular to the sun, so burning sunward would always be safe.
You can’t say that and not tell us how small Bennu is! From Wikipedia, it seems like it’s about half a kilometer wide.
