This study addresses whether service of sufficeint duration can be expected from a satellite that has been stored on orbit for significant periods of time. The question was approached in two ways. First, an extensive review of the research on orbital storage was conducted. While there has not been a great deal of published analysis of the subject, the records of those efforts are consistent in their conclusions that orbital storage does not appear to have any adverse impact on satellites or their redundant components. The second approach was empirical. A data set was collected, consisting of the dormant and post-dormant characteristics of redundant electronic boxes from 155 NASA, DoD and commercial satellites. Three separate investigations examined length of dormancy and subsequent length of activity of redundant units to statistically determine any relationship.
