... The restoration of the cruise science, however, is strongly urged for both operational and scientific reasons. COMMITTEE ON PLANETARY AND LUNAR EXPLORATION SCIENTIFIC ASSESSMENT OF THE RESTRUCTURED CASSINI MISSION October 19, 1992 At its meeting in Irvine, California, on July 16 and 17, 1992, a panel of the Space Studies Board's Committee on Planetary and Lunar Exploration (COMPLEX)

... 1,2,3,4 Since the most recent review in March 1992, 5 the mission has been restructured in order to decrease cost, increase mission resiliency and design margins, and eliminate the dependence on the Titan solid rocket motor upgrade. Because this restructuring affects the science capability of the spacecraft and the instrument complement, COMPLEX has assessed the mission in terms of the scientific impact of the revisions.

... q Previously, the power supplied by aging radioisotope thermoelectric generators would have been insufficient for alternate mission scenarios with longer flight times. Power requirements on the restructured mission have been reduced to a level that makes all backup missions viable.

... It will allow achievement of the following measurement objectives that are necessary to attain the goals listed in COMPLEX's strategy for the exploration of the outer planets. 8 These measurement goals are to: q Increase the spatial resolution of satellite coverage by repeated close flybys to allow geological assessment of the surface morphology of the icy satellites; q Obtain long-term temporal sampling of the saturnian atmosphere to better understand its dynamical properties; q Obtain higher-resolution sequential observations of ring structures to study wave phenomena and other ring aspects; q Map the magnetosphere and understand its interactions with the rings, icy satellites, Titan, and the solar wind; and q Measure the composition, structure, and circulation of Titan's atmosphere and characterize the physical properties and geographic variability of its surface.
