Data management aboard advanced spacecraft has become increasingly complex due in part to the many types of data present and an ever increasing volume of data to be managed. Data management has traditionally been a conservative practice, however, practical concerns such as system size, power, weight, and cost have created opportunities for the use of alternate technologies such as fiber optics. The use of fiber optics aboard the space station and the Small Explorer mission is evidence of this trend.
