Abstract:
While on the launch pad, Viking experienced an anomalous power turn-on that resulted in a total discharge of the spacecraft batteries. Failure analysis had not detected that discrete failure of a relay located in support equipment could have caused the problem. All interfaces with the spacecraft should be subject to failure mode analysis, status indicators or alarms should be used, and the spacecraft should not be left unattended unless periodic monitoring is conducted.
