When I was a kid, my dad worked for NASA. He was an Electronics Engineer at the Mars Station (DSS-14) at the Goldstone Complex in the Mojave Desert in California.
https://www.gdscc.nasa.gov/index.php/antennas/At the time, the Mars station was the largest movable (non-fixed) radio telescope in the world. He worked there during the Gemini and Apollo Missions, including during Neil Armstrong's walk on the Moon. He has a large certificate hanging on his wall signed by Armstrong, Collins, and Aldrin, as well as the executives of NASA and JPL (Jet Propulsion Laboratories). If I can find it, I'll post a picture of the certificate.
We would often get up early in the morning to watch rocket launches on TV. He has numerous photographs that were taken by space probe satellites of the Moon and other planets and pictures of the various antennas that were part of the Goldstone Complex.
My uncle, his brother, was convinced that the whole Moon Landing was faked. My dad explained to him what he personally witnessed which proves it happened. His brother is now a believer.
Maybe I will tell the story he told me at another time.
