Lessons Learned - Testbed Limitations May Impact End-to-End Flight System Testing
Year: 2010
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 weeks before launch had inhibited side swapping, and the testbed that had verified the changes was not capable of simulating redundancy switching. When it is infeasible to test such changes using the flight system integrated with the launch system, assure that the system testbed is fully equipped for end-to-end simulation of the flight system.
