Jupiter and Juno

Jet Propulsion Laboratory

Juno is a proposed NASA mission to achieve breakthrough observations of Jupiter’s gravity and magnetic fields, atmospheric dynamics and composition, and the coupling between the interior, atmosphere and magnetosphere that determines the planet’s properties and drives its evolution.

MSVN-JUNO is Mission Simulation Visualization Network designed for JUNO mission that can provide integrated mission operation simulation and high-fidelity visualization services to the mission teams throughout the entire mission lifecycle (Phase A to Phase E). During Phase A, MSVN-JUNO has supported collaborative mission and observation planning of the major mission events including Earth flyby, Orbit insertion, and Science orbits. MSVN-JUNO simulates operation scenarios of the mission events and accurately presents the mission state with respect to time, space, and target phenomena.

Throughout the mission, the dynamic, geometric, and radiometric relationships between the spacecraft system and the mission environment will be analyzed by integrating a wide range of models including spacecraft structure, trajectory design, attitude control, Jupiter and solar system environment, and science instruments. The mission state will be presented in multiple perspectives so that the complex dimensionality of the mission can be easily appreciated by the multi-disciplinary mission teams. The models will evolve along with the mission lifecycle tracking current knowledge of the mission system and target phenomena for continuous operability and science return validation.

The mission state visualization capability of MSVN-JUNO will be extended to visualize the telemetry data products generated by both flight system testbed and ground data system to support end-to-end information management process. During operation phase, monitoring of the three types of mission states generated by simulation process, flight system testbed, and flight system itself will enable rapid validation and optimization of operation command sequences.
