| contents | This paper presents UNAGI, a novel spacecraft mission developed by Spartan Space Systems, a student engineering team at San Jose State University, aiming for the first controlled landing on Jupiter's volcanically active moon Io. Inspired by the Japanese freshwater eel's agility, UNAGI employs an electrodynamic tether system that interacts with Jupiter's magnetic field to generate Lorentz forces, enabling dynamic modulation of the spacecraft's velocity without the need for traditional propellant. This system allows the spacecraft to precisely match Io's orbital velocity, similar to a surfer riding a wave. By optimizing tether current and orientation, UNAGI transitions from an outer Jovian insertion orbit to an orbit around Io, achieving a controlled landing for on-surface science operations. The landing is strategically timed, leveraging the gravitational influence of Jupiter and its moons to decelerate descent and mitigate impact forces.
UNAGI leverages technologies from missions like Juno, JUICE, and Europa Clipper to ensure reliable operation in the challenging Jovian environment. The mission follows a phased approach, including cruise, orbital insertion, tether deployment, Jovian orbital operations, and final descent, with extensive risk mitigation through simulations and experimental validation. The concept supports rideshare integration on future NASA or ESA missions or a dedicated launch, emphasizing cost effectiveness and adaptability. UNAGI carries a scientific payload including infrared spectrometers, magnetometers, seismometers, and chromatographs, designed to probe Io's interior dynamics, volcanic activity, tectonic deformation, and magnetospheric interactions. This mission aims to advance understanding of Io's geophysical processes and Jupiter system dynamics, setting a new standard for deep space exploration of extreme environments. |
