Paper Abstract

The Spitzer Space Telescope, the fourth and final of NASA's Great Observatories, was launched in August 2003. It has been a major scientific and engineering success, performing science observations at wavelengths ranging from 3.6 to 160 microns, and operating at present with a roughly 92% science duty cycle. This paper describes the essential role and procedures of the Spitzer Observatory Planning and Scheduling Team (OPST) in providing rapid rebuilds of sequences to enable the scheduling of Targets of Opportunity and to recover from anomalies. These procedures have allowed schedulers to reduce the nominal lead time for science inputs from six weeks to 2 or 3 days. We discuss procedures for modifications to sequences both before and after radiation to the spacecraft and lessons learned from their implementation.
