Paper Abstract

Following a brief review of the radiation environment encountered by NASA spacecraft, we present examples of the use of fiber optic and optoelectronic components in this environment. Initial results of the fiber optic experiments on the recently retrieved Long Duration Exposure Facility (LDEF) will be presented. Very little radiation induced attenuation was observed during the LDEF flight. Next, we discuss the application of a Fiber Optic Rotation Sensor (FORS) on the JPL CRAF/Cassini missions. For these relatively long missions, reliability is expected to be more of an issue than radiation damage. Finally, we briefly discuss the application of fiber optic data busses to NASA spacecraft. Because of the short fiber lengths required, radiation is not expected to be a serious problem with data link applications.
