From a study of over 300 spacecraft for which approximately 2500 malfunctions were reported, it is concluded that a decreasing hazard exists for overall spacecraft malfunctions and particularly for those due to design and environmental failures (which comprise approximately one-half of all reports). Malfunctions due to parts and quality problems show a closer adherence to the constant hazard model. Definitions required to support this study are presented, followed by an overall description of the findings, and then specific comments on various causes of spacecraft failures. The extreme value distribution is investigated as a possible model for the time relationship of some types of spacecraft failures.
