Lessons Learned – Verify Configuration of Flight Hardware Prior to Test (1998)
Year: 2000
Abstract: Abstract:
During a system-level ambient functional test of the MPL spacecraft, the software test sequence commanded the gimbaled medium gain antenna through its full range of motion, striking one of the undeployed solar panels. Confirm that developmental and flight hardware is in a configuration that has been reviewed for hardware and personnel safety prior to beginning any test sequence and that the appropriate procedure for powering down flight hardware in all test configurations under any potential emergency condition has been determined. Hold a thorough Test Readiness Review using the most current checklist that addresses personnel safety, software and hardware safety, test operations and constraints, fault protection actions, kinematics and interference analysis, commandability, emergency shutdown, and restart procedures.
