The Dawn Science Plan document. This document provides a description of the   
planned Dawn observations throughout the mission from launch through Vesta.   
It is provided as a source of information on the intent of the observations   
made by the instrument teams at Vesta. Note that not all of the planned       
observations actually occurred due to a variety of instrument resets and      
spacecraft safings.
