Abstract:
Early in the Mars Exploration Rover (MER) design phase, and in all modeling for operations and mission science return, planners assumed that each rover would be inoperable every third day, on average, due to problems. This planned margin contributed to mission success by giving operations personnel time to gain an understanding of problems, and to plan high-risk maneuvers, before taking action. For complex missions, provide sufficient margin in the planned mission science return to accommodate likely interruptions in the data flow.
