One of NASA's primary concerns is the improvement of spacecraft performance over time. As a first step in defining generic approaches for improving spacecraft reliability and longevity, comprehensive data on spacecraft anomalies, failures, and performance degradation as a function of time were collected, analyzed, and documented. Analytical techniques included categorization of anomalous incidents, engineering analyses of particular classes of anomalies, and mission effectiveness assessments versus time. Representative results: five classes of anomalies account for 50 percent of all in-flight problems; half of all spacecraft continue to report significant RFI/EMI problems; and missions are generally much more than 50 percent effective far in excess of their design lives.
