Space System Modeling Approach for Exploring of the Iced-Covered Ganymede Moon Subsurface Oceans

The presence of a subsurface ocean on Ganymede moon, the largest and the only moon of solar system that has global magnetic field, marks the existence possibility of sustainable life ecosystems. The phases of this mission involve to launch spacecraft from Earth or the Moon to be landed on the Ganymede moon, using satellite constellation about Ganymede moon, to drill the icy crust of Ganymede moon, reaching the subsurface ocean, and placing submarines or submersibles in the subsurface ocean. The process involves obtaining a sample, analyzing the sample, performing documentation, and reporting the Data to DSN. In this research study, the approach to modeling space systems aims to achieve a mission probability of success of 99% and better, as the author's plans & approach are depicted in Figure.1. The context diagram of this research project encircles active, passive, and paying external stakeholders, with detailed specifications provided in a hierarchy diagram for a probe exploration mission on Ganymede, one of Jupiter's moons. The Pugh diagrams was used to evaluate drilling methods for the Ganymede mission. Quality Function Deployment (QFD) at Level-3 aligned stakeholder needs with engineering design, ensuring mission objectives were met. A Functional Flow Block Diagram (FFBD) illustrated mission workflows, while a risk matrix identified and mitigated potential mission risks.
