Abstract
Over the last twelve years, the Space Telescope Science Institute (STScI) planning and scheduling teams have reduced the lead time to schedule the Hubble Space Telescope (HST) five-fold while doubling the overall observing efficiency. After the launch of HST, a one-week flight calendar took 56 days to prepare, schedule, and convert to flight products; the process now begins 11 days before execution. Early observing efficiency was in the 25% range; it is now typically 50%. In this paper, the process improvements that allowed these advancements are summarized. We also discuss the most recent scheduling advancement, which allows interruption of an executing flight calendar for fast-turnaround science observations or telescope anomaly resolution within 24 hours of activation.
