NASA-LLIS-3716: Lessons Learned - Testbed Limitations May Impact End-to-End Flight System Testing
Abstract: Abstract:
After 11 year of spaceflight, it was discovered that the dual string Stardust/NExT spacecraft was incapable of switching to the redundant flight system. Flight software changes made only 3 ...

NASA-LLIS-1713: Lessons Learned - Simulate the Launch Site RF Configuration During I&T
Abstract: Abstract:
Science data losses during compatibility testing at the CloudSat launch site were traced to an RF cabling configuration that differed from the cables, couplers, and attenuators used during ...

NASA-LLIS-6216: Lessons Learned - MSL Mobility Assembly Lift Mishap
Abstract: JPL flight hardware was damaged during a lift operation preceding a test of the MSL rover Mobility Assembly due to an undetected mechanical interference that was signaled by an anomalous load cell reading. The load cell ...
NASA-LLIS-1743: Lessons Learned – Mitigating the Risk of Single String Spacecraft Architecture
Abstract: Abstract:
Mars Exploration Rover met and exceeded mission requirements despite a largely single string spacecraft architecture. Balance the risk of a single string flight system with effective risk ...

NASA-LLIS-2419: Lessons Learned – Aquarius Reflector Over-Test Incident
Abstract: Abstract:
The Aquarius reflector was damaged by over-testing during a 2007 test in the JPL acoustic test chamber. The root cause was attributed to a procedural deviation, and the proximate cause was ...

NASA-LLIS-3516: Lessons Learned - Lithium-Ion Battery Fire
Abstract: Abstract:
A lithium-ion battery undergoing characterization testing in a basement laboratory overheated, caught fire, and detonated, funneling toxic fumes into the two upper floors of the office building ...

NASA-LLIS-6196: Lessons Learned - Shaker Self-Check Unexpectedly Exceeded the Dynamic Test Limit
Abstract: Shaker system control software generates a self check immediately prior to a test at a signal level that is normally considered to be of insignificant strength compared to test levels. During a dynamic test of the Juno ...
