Lessons Learned – Test Contingency Planning Should Consider Facility Power Interruptions (1996)
Year: 1998
Abstract: Abstract:
During a regional public service power outage, an unplanned facility power loss occurred during system level thermal-vacuum test of the Mars Global Surveyor. This resulted in a slight inflow of external unfiltered air into the propulsion system through its Ground Support Equipment (GSE) pressure control system -- a potential contamination concern. Test contingency plans and FMEAs for ground support equipment should consider responses to facility power interruptions. Test facilities should have devices to maintain a safe spacecraft environment in the event of a facility power loss.
