It's not easy to ferret out what NASA used. Many military aerospace
projects are classified, so we have no idea what they used. The 1802 was
a logical choice.
The web is helpful, but is not a very reliable source of data. You can
find correct answers, but also every permutation of wrong answers to
most questions. :-)
One little nugget I can add: Ham radio operators have been building and
deploying their own amateur satellites since 1972. They formed AMSAT
(AMateur SATellite Corp), which has built a long line of OSCAR
satellites, getting them into orbit by "hitchhiking" a ride on various
government and commercial launches (the ham satellites are used as
ballast or filler in some other mission).
Anyway, the Jan 1979 issue of Byte Magazine had an article "IPS: An
Unorthodox High Level Language" by Dr. Karl Meinzer. It described a
version of FORTH that was used on the 1802 in the ham's OSCAR
satellites. I haven't found dates for all the OSCAR launches, but AMSAT
OSCAR-10, launched in 6/16/1983, definitely had an 1802 on board. This
definitely precedes Galileo's launch in 1989.
