The Cassini mission will be launched in April 1996 and will arrive at Saturn in December 2002. Upon arrival, a large maneuver near Saturn periapsis called Saturn Orbit Insertion (SOI) will reduce the energy of the spacecraft and result in capture into Saturn orbit. SOI is one of the most critical events of the entire mission. Therefore it is prudent to determine what resources must be dedicated to assure successful execution of SOI and what operational resources can be provided to satisfy SOI science objective. To prolong undisturbed science observations near the periapsis, a delayed SOI burn strategy has been developed. To examine potential resource conflicts between science and engineering activities, key considerations such as power and data storage capability have been evaluated. Other constraints such as turning the spacecraft to burn attitude and slewing platforms for science have also been examined. Although there are many constraints and the spacecraft resources are limited, a reasonable amount of science can still be carried out prior to and during the SOI burn.
