Lessons Learned - Anomalous Flight Conditions May Trigger Common-Mode Failures in Highly Redundant Systems
Year: 2007
Abstract: Abstract:
After launch, MRO was found to be susceptible to a solar flare event during the critical aerobraking phase of the mission that could corrupt the multiply redundant identical file systems in the Command & Data Handling subsystem. This could have caused a mission failure during aerobraking if the files had been needed for entry into safe mode or to perform an SEU-induced reboot of the flight computer. Assure that fault tolerant designs reflect full consideration of anomalous conditions that could trigger common-mode failures.
