See, the problem with this prompt is that every corporation lies and hides something, even if it's part of the government. Confidential projects buried, senior staff corrupted, that sort of thing. However, this evidence is lackluster for NASA, especially given certain events that wouldn't make sense for a conspiracy. For example, the moving of the Endeavor.
This was a huge project, caused massive disruptions, and was a giant pain. Even if we assume this is a fake shell, as it would be in a conspiracy, why do any of this? It doesn't prove authenticity, because people will take videos and photos of the (in this scenario) fake launch. On a purely logisitical level, this is a lot of effort for something that wouldn't prove anything.
