Lessons Learned – Galileo Scan Platform Anomaly at Ida Encounter (1993)
Year: 1997
Abstract: Abstract:
A scan platform anomaly occurred shortly before Galileo's encounter with the asteroid Ida. Because the Galileo architecture did not provide for revolving, short-term storage of downlink data, ground control lacked insight into the cause of the incident.
Missions should continuously buffer at least a small amount of high-rate telemetry as it is being downlinked at a lower rate. Storage of high-rate data for the period immediately preceding and following a fault would assist mission analysts in diagnosis of the problem.
