Operation Vesta: Pluto's Devious Plan to Regain Status?

With the New Horizons spacecraft hurtling toward its 2014 encounter with Pluto, and with the Dawn spacecraft now at its most up-close and personal encounter with Vesta, we are in the process of learning scads of information about two objects that are among the least understood and most under-explored bodies in the Solar System.
