Landing or crashing is not considered an option since the spacecraft is not sterilized. Apparently, this would violate NASA Planetary Protection Protocols for Ceres.
Of course, that begs the question of what the plan is should a flyby of any target of opportunity not be possible. I'd guess that would leave just escaping Ceres in a non-targeted way or at the very least raising the orbit as high as possible before the xenon is exhausted and/or a critical failure occurs that renders the spacecraft uncontrollable. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
