More than halfway into its primary orbital mission, MESSENGER has successfully exploited the SciBox planning and commanding system to automate science observation scheduling and command generation for its full instrument suite, as well as its radio-frequency communication and guidance and control systems. MESSENGER's SciBox software coordinates instrument observations to determine the optimal conflict-free science schedule for the entire orbital mission and generates weekly command sequences for submission to mission operations. SciBox maximizes science return by filling all available observing opportunities and fully utilizing onboard storage and downlink bandwidth. As of four months into its one-year orbital mission, MESSENGER SciBox had scheduled the acquisition and downlink of nearly 40,000 images and comparable data sets from the spacecraft's six other instruments. The flexibility of MESSENGER SciBox allows for rapid re-optimization of schedules in the event of unforeseen circumstances. It has also allowed the science and planning teams to analyze rapidly the effects of modifying operational parameters and adding new observations. Within two hours, the entire mission can be re-optimized, schedules and command sequences generated, and a full set of plots and reports produced. The effects on resource usage, observational coverage, and compliance with operational constraints may be quickly assessed. This rapid turnaround ensures that optimal schedules are produced regardless of circumstances. We present an overview of the MESSENGER SciBox design and its operation.
