Science Planning And Commanding For Jupiter

NASA's Juno spacecraft launched in 2011 and arrived at Jupiter in July 2016. Eleven onboard science instruments are studying our solar system's largest planet for 30 months while passing through the strongest radiation field that any spacecraft has seen to date. The science planning and commanding process for Juno is complex.Juno is a three axis spin-stabilized spacecraft with large solar arrays that are always kept pointed toward the sun. The Jupiter Energetic particle Detector Instrument (JEDI) team supports three nearly identical versions of the instrument mounted on the spacecraft to maximize coverage of the sky. JEDI principally detects energetic electrons and ions, with some species separation, over a wide energy range. The instruments were built at the Johns Hopkins University Applied Physics Laboratory where the Payload Operations Center is also located.A combination of institutionally provided tools along with science instrument team tools must work in harmony to create the products necessary to support the planning and commanding process. This paper will describe the process that the JEDI scientists and engineers go through to allocate resources, coordinate planning, and build, test and execute the spacecraft and instrument commands to achieve the mission.
