It gets kinda interesting when actual government policies are involved:
In 1980 Robert Heinlein was a member of the Citizens Advisory Council on National Space Policy, chaired by Jerry Pournelle, which met at the home of SF writer Larry Niven to write space policy papers for the incoming Reagan Administration. Members included such aerospace industry leaders as former astronaut Buzz Aldrin, General Daniel O. Graham, aerospace engineer Max Hunter and North American Rockwell VP for Space Shuttle development George Merrick. Policy recommendations from the Council included ballistic missile defense concepts which were later transformed into what was called the Strategic Defense Initiative. Heinlein assisted with Council contribution to the Reagan SDI spring 1983 speech.
