> rockets are like that: they don't care what they are pushing or in which direction

That is just incorrect. Fuel tank design and arrangement, for example, is full of internal mass dynamics.

> would be politically complicated for NASA

Let me repeat this again: Falcon Heavy cannot carry Orion. There is no complication here.

NASA and SpaceX collaborate heavily. NASA doesn't build rockets, they're administrators. If SpaceX could be used, they would have used it (as they did with Dragon and so many other projects).

Stop trying come up with makeshift excuses for the lack of technical background you failed to provide.

> Both Challenger and Columbia were lost because people forgot they were experimental vehicles operating under conditions we don't fully understand.

Irrelevant attempt at misdirection. This has nothing to do with whether Falcon Heavy can or cannot test Artemis shields.

You're desperately trying to pivot the discussion from a technical one (in which you demonstrated lack of basic knowledge about several important topics) to a political one (which is murky and easier to navigate into a tarpit).

Why? Explain your reasoning.

I already did.

Initially, I presented it as "please elaborate" questions. A courtesy, to give you the benefit of the doubt.

So far, you were not able to answer them with the same kind of courtesy that I initially offered.

Instead, you doubled-down on answering vaguely, hoping that I would slip at some point to a defensive position in which I would offer math and numbers, which are totally YOUR responsibility to provide, since YOU MADE THE CLAIM.

I don't need to prove that something that never happened is impossible. You need to prove that what never happened is possible (because you said it is). Capisce? It's basic science communication.

I don't need to do anything here. I'm right until you're able to prove otherwise.

It’s painfully obvious you never worked in any position remotely close to the aerospace industry.
Never said I did.

At an enthusiast-level of knowledge (which is the level we're discussing here), I am way far ahead of you on this.
