Abstract:
A SEASAT-A subassembly was damaged during thermal-vacuum test due to the configuration of GSE test equipment. A reed relay in a commercial data scanner was connected to circuits requiring +5 volts; its failure permitted the SEASAT-A circuits to be exposed to scans as high as 31 volts.
It is important to assess the design of commercial support equipment and consider what a failure of an internal part might do to the flight hardware.
