Limitations of Spacecraft Redundancy: a Case Study Analysis
44th International Conference on Environmental Systems Paper Number 13-17 July 2014, Tucson, Arizona Limitations of Spacecraft Redundancy: A Case Study Analysis Robert P. Ocampo1 University of Colorado Boulder, Boulder, CO, 80309 Redundancy can increase spacecraft safety by providing the crew or ground with multiple means of achieving a given function. However, redundancy can also decrease spacecraft safety by 1) adding additional failure modes to the system, 2) increasing design “opaqueness”, 3) encouraging operational risk, and 4) masking or “normalizing” design flaws. Two Loss of Crew (LOC) events—Soyuz 11 and Challenger STS 51-L—are presented as examples of these limitations. Together, these case studies suggest that redundancy is not necessarily a fail-safe means of improving spacecraft safety. I. Introduction A redundant system is one that can achieve its intended function through multiple independent pathways or Aelements 1,2. In crewed spacecraft, redundancy is typically applied to systems that are critical for safety and/or mission success3,4. Since no piece of hardware can be made perfectly reliable, redundancy—in theory—allows for the benign (e.g. non-catastrophic) failure of critical elements. Redundant elements can be 1) similar or dissimilar to each other, 2) activated automatically (“hot spare”) or manually (“cold spare”), and 3) located together or separated geographically5-7. U.S. spacecraft have employed redundancy on virtually all levels of spacecraft design, from component to subsystem7,8. Redundancy has a successful history of precluding critical and catastrophic failures during human spaceflight. A review of NASA mission reports, from Mercury to Space Shuttle, indicates that redundancy has saved the crew or extended the mission over 160 times, or roughly once per flight9. -
