The history of the Main Electronics Box (MEB), a description of the the assembly, and handling conditions following the Solar Maximum Repair Mission are contained.
The SMM satellite was launched in February, 1980 with a complex of instruments designed to study the active sun. The HAO instrument (c/p) operated satisfactorily until July when a series of partial failures began. This report describes analysis and resolution of problems up to the terminal failure on September 23, 1980. The MEB was replaced in orbit in April, 1984, restoring the observational capability of the c/p instrument. The process of trouble-shooting and restoration of the failed MEB at GSFC is described. Conclusions are presented regarding the cause of the failures encountered.
