Applying the Lessons Learned from HST Operations to New Missions Glenn Miller and Peg Stanley (STScI) With the operation of the Hubble Space Telescope, the Space Telescope Science Institute pioneered the large scale application of non-traditional operations models including integrated (queue) scheduling for increased scientific return, service observing, multi-year long-range planning of and automated planning of observations. This paper discusses the key aspects of HST operations, our experience over the past 7 years, including concepts which worked well and those which did not. We discuss how this experience can be applied to new ground- and space-based missions.
