Saturn's Shepherd: Prometheus

The purpose of this mission is to explore the surface of Prometheus and its interactions with Saturn’s F Ring. While Prometheus acts as a ‘shepherd’ for the F Ring’s particles—controlling and limiting their spread by its gravity—Cassini also observed Prometheus creating gravitational anomalies within the ring. A primary aim of this mission is thus to study the interactions between Prometheus and the F Ring- and to determine what other objects (such as moonlets) are shaping the F Ring. An orbiter will be sent to orbit near the outside of the F Ring to study these interactions. The orbiter will be equipped with several instruments, including a telescope, spectrometer, and dust analyzer similar to the Cosmic Dust Analyzer used on Cassini. As solar panels are ineffective this far from the sun, the mission will utilize a radioisotope power system to extend the orbiter’s lifespan. The second objective will be to send a lander to the surface of Prometheus. Current understanding of Prometheus’s craters is that they appear soft due to the heavy amount of dust on the surface. The primary goals of the lander will be to use an X-ray diffraction sensor to study the accumulated dust and determine the components of the surface. RPS will aid this part of the mission as the lander’s systems can continue operation in extreme cold. My power—empathy—will ensure success. This mission will be multifaceted and complicated. It will require a large team and likely experience several problems. I can use my power to recognize when someone needs help. I can guide the team through problems and foster a positive, collaborative work environment.
