MSVN-Juno

The Juno spacecraft is planned to launch in August of 2011 and would arrive at Jupiter five years later. The spacecraft would spend more than one year orbiting the planet and investigating the internal structure; determining the amount of global water and ammonia present in the atmosphere, studying convection and deep-wind profiles in the atmosphere; investigating the origin of the Jovian magnetic field, and exploring the polar magnetosphere. Juno mission system management is responsible for mission and navigation design, mission operation planning, and ground-data-system development. In order to ensure successful mission management from initial check-out to final de-orbit, it is critical to establish clear mission objectives for all project teams to comprehend and contribute. This paper presents MSVN-Juno, a suite of simulation systems developed on the MSVN-framework to establish the project-wide shared vision. The MSVN-framework is composed of three functional layers, mission information modeling, virtual prototyping, and virtual operation, to achieve responsiveness and effectiveness of mission simulation product development. MSVN-Juno simulations have focused on critical mission phases including the Earth-gravity-assist maneuvers, the Jupiter-orbit insertion, and the 32 science orbits.
