  Redundancy

Most systems on the spacecraft are fully redundant. This means that, in the event of a device failure, there is a backup system to compensate. A software fault protection system is used to protect the spacecraft from reasonable, credible faults but also has resiliency built into it so any faults not anticipated can be accommodated without placing the spacecraft in a safe state.
