In-Flight Modification of the CassiniReference Trajectory

摘要

In July of this year, Cassini completed its four-year prime mission of Saturn exploration, and began a two-year extended mission, the Cassini Equinox Mission (CEM). During the course of the Cassini prime mission, several changes were made to the reference trajectory either out of necessity (i.e. due to spacecraft safety concerns) or to increase the mission science return by following-up on new discoveries.
