Let's use the imagination. probably 200-300 people in the full know and orchestrating everything. This could be like ten groups of twenty people, or 30 groups of ten people (teams) all with their own specialties. Writers/story telling gurus , science theorists/consultants, engineering specialists, news/pr specialists, human resource specialists, education specialists (crowd source smartest kids on the planet how to make a rocket fly through space to Mars on paper agreeing with all assumed math), project managers, foreign consultants, a treasury department, strategists, visual and artistic department etc. All these teams have their own teams of people not in the know (example the welders, fabricators, engineers, artists, etc, the janitors). I would guess like I said 200-300 people, and probably another 2000-3000 (may be much higher) performing sensitive work and likely could be suspicious or know and they don't care and just want to get paid, scared etc. The majority of NASA employees likely not in the know. Astronauts definitely paid liars. The total number of individuals indirectly helping the cause I would guess is over a million people.
