Applying the lessons learned from HST operations to new missions

In order to use the next generation of space and ground based observatories for the greatest scientific benefit, the experiences of current missions should be carefully examined to find strategies which have worked well and also to identify areas where new paradigms are needed. With the operation of the Hubble Space Telescope, the Space Telescope Science Institute pioneered the large scale application of non-traditional operations models including observation preparation tools, integrated (queue) scheduling for increased scientific return, service observing, and multi-year long-range planning. This paper discusses the key aspects of HST operations, 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.
