In the public's mind SpaceX "out NASAed NASA."



Everyone who is paying attention has heard Elon Musk comparing vintage rocket launches to junking a Boeing 747 after one flight. SpaceX has dramatically reduced the costs of rockets and launches, and has developed better ways of doing things over NASA and its competitors.


In all the interviews I have heard Elon Musk give, he would not say, when asked, why every other rocket company (excluding Blue Origins) used expendable rockets.



Spread the Wealth

Until recently, most rocketry projects were nationalized. In the USA, NASA contracted with suppliers across the nation to build rockets, the shuttles, capsules. The process was politicized, meaning parts were manufactured in various states to ensure votes in Congress for NASA's budget. Very expensive.



Recently the German partner in the EULA space program said it could not emulate SpaceX's re-usable rocket business practice since it would displace thousands of German workers.


Since SpaceX does the opposite, it has a huge leg up on it competitors.



The Mars Program

Some things that are in front of your face, you miss. Why? Who knows? In Kubrick's movie '2001,' we all saw the spinning white centrifuge in which one of the astronauts was running, and in which one of the astronaut conversed with HAL, the ship's super computer. But in the exterior shots of the space ship, where is the great spinning wheel? And is not HAL just a transposition of the letters IBM? (Excuse the Nerd stuff.)


Has anyone figured out that the super tech Elon Musk is working on, is what we will need on Mars?

We've known for decades that re-usable rockets would be more economical. The Space Shuttle was NASA's attempt to implement that. The problem is that making the leap to fully re-usable hardware from expendables is an expensive and risky proposition. The Shuttle was never sufficiently funded to achieve that goal, so it ended up as a giant albatross and a financial disaster. I think Elon Musk is likely the first person to come along with enough interest, cash, and a will to succeed despite the odds, that he could have a go at it.

In some respects it reminds me of the story of the Supermarine Spitfire -- a racing aircraft that was partly financed by Lady Lucy Houston.

I suspect musk has spent far less developing falcon than NASA spent developing the shuttle.

Oh for certain. A crew-only vehicle is much lighter and cheaper. The shuttle design carried way too much mass up to orbit and back, when really most of it should have been designed to stay in orbit. I guess they were thinking it would need to carry back a lot of extra cargo? All you really need to carry is the crew, then having a orbiting work vessel to supply the arm and propulsion.

Regarding the centrifuge of the Discovery One spaceship, one opinion shows it located in the orb-like front section. Here are some diagrams. No idea if that's true or not though. But it would be a conceivable location.

About HAL, it's supposed to be an acronym for Heuristically programmed ALgorithmic computer, manufactured in Urbana Illinois. However, IBM's logo is indeed featured on the wrist control pad on Bowman's space suit. Although we might not know the whole story, it appears that IBM might not have wanted its logo associated with a psychotic computer. To get around that, it's been suggested that the letters following IBM would be HAL by shifting each letter by one. H>I, A>B, and L>M. So, yes, it could be a transposition. It's also shown on the computer display's console in the Pan Am ship's cockpit as its docking with the torus space station.

It's also been suggested that IBM can be seen from the outside as a reflection on Bowman's face, but there are problems about that. For one thing, if it was a reflection of IBM, the letters would be mirrored in reverse. There has been some suggestion that it might not be IBM, but rather MGM, which was the distributor of the movie. There are pros and cons about it. It's certainly possible it is IBM, but why a forward reflection rather than reverse? Kubrick was a stickler for detail.

Falcon 9 was developed for less than $400 million. NASA spent more than that on building the launch support tower for Ares 1.

They do benefit financially by using existing launch infrastructure provided by NASA.

Musk will be known in history as the great salesman in his time.

I believe they lease the actual pads etc., but there's no denying that SpaceX and other aerospace entities benefit tremendously from NASA research. Which is good, because that's NASA's purpose.
