So what? The rocket launch might be real, but not the mission itself and the details about it. How difficult is it to launch a dummy rocket which disintegrates in the higher atmosphere and then pretend you're recovering something from the ocean? Do you really believe that after so many space missions all the photos and videos from space look like garbage? The Earth looks like nothing, the imagery is actually inferior to what we see in most sci-fi movies. How about the Sun why is it never blinding? Where the heck are they hiding that it is always relatively dark? I am not talking about the background, but about the spaceship itself. I would expect it to be super shiny, so bright in fact that a photo would be difficult to take. If you were to believe videos and photos then perhaps you should believe that the actors in Interstellar really flew to Saturn and went into another galaxy through a black hole. I won't be surprised if after a few decades NASA(or the fake 'private' space companies) actually start pretending to have achieved something like that. People would believe it anyway. It is incredibly stupid propaganda. Don't you realize that you believe everything you're shown?
As always, your flat earth claims rely on a massive, yet completely unproven, conspiracy. In this case, you admit that a rocket was launched but your theory (without evidence, as always) is that NASA intentionally blew up the rocket, waiting, I suppose, until it was too far away for amateur astronomers to see it. Then they pretended to recover the rocket from the ocean.
Here's the problem (the same one that all of these idiotic theories have): dozens, if not hundreds, of people would have to keep this secret. The whole scam would come crashing down if a single NASA employee who knows about it were to send an anonymous tip to the New York Times. Or if just one disgruntled Navy sailor on the ship that went to pick up the non-existent rocket blew the whistle. Or if just one retired NASA official decided to tell the truth while on his deathbed, since he feared dying without telling the truth. But not a single one of the thousands of people who has known this amazing secret since the Apollo program started has EVER leaked the secret.
Deep Throat leaked to the Washington Post and brought down President Nixon. Edward Snowden leaked tons of NSA information to the government's great embarrassment. Julian Assange leaked tremendous amounts of secret information from many countries. And numerous American whistleblowers tell the truth all the time because they believe it's the ethical and honorable thing to do. Yet no insider has ever revealed that NASA, the satellite industry, private rocket industry companies and astronomy and aerospace engineering itself are all hoaxes. No one, ever, has done this. And that's because the government has issued threats to thousands of people that their families will be killed if they reveal the secret? And not one of those threatened employees was upset enough about this threat to provide anonymous information to a journalist?
