Not only did they fake the moon landings but they fake most things space related. Most of the videos put out by NASA are CGI; photos are photoshopped. But they'll also tell you that it has to be that way (and that's part of how they fool everyone).
For example, the recent NASA DART mission. The claim from NASA is:
Now take a look at some of their CGI fake footage of the mission, where they claim this DART satellite is traveling to "an asteroid 7 million miles from earth", and "closing in at 4,000 miles per second". That's 14.4 million miles an hour.Double Asteroid Redirection Test was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects. It was designed to assess how much a spacecraft impact deflects an asteroid through a transfer of momentum. The asteroid selected for the test poses no actual threat to Earth.
