NOAA's National Geophysical Data Center (NGDC) in Boulder, Colorado, maintains a data base of spacecraft anomalies, ranging from minor operational problems to permanent spacecraft failures. The data base includes anomalies primarily from geostationary spacecraft as well as near-Earth and interplanetary space failures. It currently contains 2779 events from 1971 to the present. Events were contributed from seven countries: Australia, Canada, Germany, India, Japan, the U.K., and the U.S.A. Data suppliers usually provide the anomaly type and diagnosis. The Spacecraft Anomaly Manager (SAM) software allows the user to select specific anomalies and to depict them in local time and seasonal histograms. SAM was designed as a tool to investigate the relationship between anomaly frequency and environmental factors.
