If you are referring to the RCA 1802 chip, that is incorrect.

Members of the Yahoo COSMAC ELF group have verified that ONLY the Galileo spacecraft used the 1802.
Neither Pioneer, Viking, Voyager, nor any other spacecraft, used the 1802.
(the Space Shuttle MIGHT have used one in one of its systems)
There are a few Earth-orbiting satellites that used the 1802. (OSCAR?, ...)
