Originally posted by svauto-erotic855 View PostAir planes are made on an assembly line and they are still expensive despite a massive demand for them. Rockets are much simpler than a commercial jet. Changing building techniques and going to a simpler design would drop the cost massively for SpaceX but the engineering cost for the redesign would be massive. The old school rocket engines and the supporting hardware is extremely expensive. It was designed with a cost is no object attitude and was very over built because failure was literately not an option and the project at hand was a race against the clock with no time for even considering changing the direction they were going.

Everyone who gets satellites launched by SpaceX seems to be happy (except Facebook) as well. He's launching quickly, and re-launching rockets. Only a matter of time before it becomes economical.
He's also well versed in rocket science, something he did not study originally.
I would call that more than a "hype man".
I never said that people who are dealing with SpaceX are not happy. I said that the purpose of both companies is to fund Mr Musk ride to Mars; profit is not a factor and it is very unlikely there ever will be one unless it just come from selling the companies stock and that will only net a profit for the seller of the stock.
I call him a hype man because he is selling a dream and is very, very good at doing so. Tesla has never made a profit and is so far away from doing so it is like it is orbiting a far away star. The exact same thing can be said of SpaceX. There is no there there, at the end of the day there is only the dreams of Mr Musk and dreams are the most powerful ideas of all.
Rocket science is not that hard to understand if you have an engineering back ground like I do but I will be the first to admit that the devil is in the details. There is truly nothing new that SpaceX is doing except for trying to reuse a booster. Their designs are a tried and true type that any engineer from NASA in the late 60s would instantly recognize and could work on. Unfortunately those tried and true designs were designed by an engineering team working in a program where cost did not matter and are more complex than they need to be and are very expensive. Why do you think a fuel tank with a combustion chamber and a nozzle on the end of it (aka a rocket) cost 60,000,000 dollars?

Originally posted by svauto-erotic855 View PostFrom an engineering stand point they were doing fine. What they could not compete with is the cult of personality that is Mr Musk. Just ask yourself how much actual profit SpaceX has generated and if they even have a working plan to generate a profit anytime in the future. Most of the gains in anything Musk has touched since they sold PayPal has simply been from promoting the hell out of it and not from actually selling a product or service. He is a brilliant visionary and hype man and that is about it.

Another launch is scheduled for Sunday. That'll be three flights in 10 days. I think it will also break the record for the most launches in a year by any company.

Do you seriously think you know better than the entire industry? Of course you do...because you are skilled enough to repeat the same dumb shit you hear from the random source of the day.

Originally posted by svauto-erotic855 View PostI am not saying that at all. I am saying that the fuel pump is the most expensive part on the entire rocket and I would simply get rid of it. The system that back fills the fuel tank also cost a ton and can be done away with. The nozzle of the engine get heavy deposits from combustion that have to be removed and the hole the fuel passes through gets eroded. The nozzle also is put under extremely high pressure and temps and at time has to be replaced. The pressure in the open nozzle hits as high as 15,000psi and there is a delicate balance between enough strength while keeping the weight low. The surface area for the pressure to act on is huge.
How can you remove a fuel pump? Don't you need something to pump the fuel? Gravity only works when the engine is burning right? Helium keeps fuel pressurized, but not enough to pump a giant rocket engine is it?
