“…The Cassini-Huygens mission started in 1989 as part of NASA's Mariner Mark II program 3 which was initiated in 1987. In 1992, the mission and spacecraft were both redesigned which resulted in a simplified implementation of original scientific goals and engineering capabilities.…”

Simulation environments have been an integral part of Cassini's heritage. From the time of flight software development and testing to the beginning of the spacecraft's extended mission operations, both softsim and hardware-in-the-loop testbeds have played vital roles in verifying and validating key mission events. Satellite flybys and mission-critical events have established the need to model Titan's atmospheric torque, Enceladus' plume density, and other key parametric spacecraft environments. This paper will focus on enhancements to Cassini's Flight Software Development System (FSDS) and Integrated Test Laboratory (ITL) to model key event attributes which establish valid test environments and ensure safe spacecraft operability. Comparisons between simulated to in-flight data are presented which substantiate model validity.

“…NASA's Mariner Mark II program began in 1987. In 1989, the first two spacecraft missions were initiated from this program: 4 Cassini-Huygens to Saturn and Titan, and the Comet Rendezvous/Asteroid Flyby (CRAF). Both missions, with very different payloads and scientific objectives, were to be very similar in design goals.…”

The Cassini Attitude and Articulation Control Subsystem (AACS) Flight Software (FSW) has achieved its intended design goals by successfully guiding and controlling the Cassini-Huygens planetary mission to Saturn and its moons. This paper describes an overview of AACS FSW details from early design, development, implementation, and test to its fruition of operating and maintaining spacecraft control over an eleven year prime mission. Starting from phases of FSW development, topics expand to FSW development methodology, achievements utilizing in-flight autonomy, and summarize lessons learned during flight operations which can be useful to FSW in current and future spacecraft missions.

“…[2] Because of their great distance from the sun, both missions will be powered by RTGs (Radioisotope Thermoelectric Generators). Since the planned schedules do not allow sufficient time for development and flight qualification of new RTG designs, both missions will use generators that are essentially identical to the GPHS-RTGs [3,4,5] flown on the recently launched Galileo and Ulysses missions.…”
