| description abstract | Abstract: During final assembly of the Deep Space 2 (DS2) Mars Microprobes, each of the two flight probes was inadvertently powered. The design of the mechanical switches was found to permit inadvertent ground paths during assembly, which could cause loss of mission due to undetected battery depletion prior to launch. System design must address hardware performance during assembly and test as well as during flight. Safing devices should be operational throughout assembly and test operations. Design analyses such as FMEA, SCA, and FTA must examine the electrical implications of mechanical/packaging design decisions. | |
