Falcon 9 Is Now Fully Integrated At Cape Canaveral
RobGoldsmith writes "SpaceX's Falcon 9 is now fully integrated: an update from Elon Musk states 'Falcon 9 is now fully integrated at the Cape! Today we mated the 5.2 m payload fairing to the Falcon 9 first stage. This was the final step in the integration process — one day ahead of schedule.' New images are now available showing the first fully integrated Falcon 9 Rocket. Once the launch mount and erector are complete, SpaceX will transfer Falcon 9 on to the erector and raise it to vertical early in 2009."
I thought it was proper to erect first, then integrate?

Sounds like some spam I've been getting.
I think there is an opportunity for a small aerospace firm (Scaled?) to build a capsule similar to Gemini, or a small Apollo. Maybe you could sell single use capsules for a million bucks a go, ready to integrate with a Falcon 9.
I also think it should be possible to build an ultra light capsule to fly on a Falcon 1. The mass budget is about 500kg which should be enough in this day and age.

If the Ares I design is to be replaced, it would be by the Delta IV Heavy, not the Falcon 9 Heavy. The Delta IV Heavy is already flying, its payload fairing size is an almost perfect fit for the Orion spacecraft, and it uses the RS-68s that are planned to be used on the Ares V. NASA would also be extremely skeptical of the Falcon 9 Heavy because it would be using a total of 27 Merlin engines in its first stage! The failures of the N1 rocket (with 30 engines) would make any high engine rocket a tough sell. The Falcon 9 may work, but I'd be very surprised if the Falcon 9 Heavy is ever built. Man-rating a rocket like that would be well-nigh impossible.

Please read my comment again.
I said Ares I / Orion replaced by the Falcon 9 / Dragon. Not the Falcon 9 Heavy being used to lift the Ares I.
And actually, it's not even necessary to launch the Ares I design on the Delta IV Heavy, just an Atlas V, according to some.
I suspect there's a longer-term plan to swap out the 9 Merlins on the bottom of the Falcon 9 with two bigger rockets. Except that nobody inside of SpaceX is going to breathe a word about it until the right time.

Um, SpaceX is also working on their own capsule, called the Dragon, to be launched atop the Falcon 9.

Here's a question for those of you who know more about the details of space engineering than I: One of the changes made to the STS during the early days of flight was that the main tank was left unpainted. This gave the Shuttle launch stack its trademark rust-orange color. By making this simple change, NASA realized they could shave off hundreds of tons of launch weight, thereby increasing available payload. (Not that the shuttle ever used it, but that's another issue.)
Yet I can't help but notice the shine of a fresh coat of pain on the Falcon rocket. They even went through the trouble of stenciling "SpaceX" in large letters along the length of the craft. Is there any particular engineering reason why rockets are still covered in paint, or is this entirely an aesthetics issue?

yes, the falcon 9 heavy *does* use 27 engines in total. thats the freaking point. if a any one of the few engines on a delta IV fails, the rocket is a goner. if a engine, or even a few, fail on the falcon 9, it can still complete its mission, the other engines just have to burn a bit longer. its engine redundancy, in the fine tradition of rockets like the saturn 5, which had no failures, despite a engine failure mid-flight on apollo 13.
You are out by several orders of magnitude - 600lbs / 272kg was the weight saving from not painting the ET. Later structural design changes reduced the ET weight by a more significant 17,000lbs.
Reusability isn't mentioned on their Falcon 9 page anymore. I originally got excited about SpaceX because I thought reusability would be the breakthrough in space launch we need. But unfortunately Musk said they haven't come up with a way to protect the boosters from reentry yet. They're looking at aerodynamic methods to keep the heat shielded top of the booster coming down first. Some engineers say they're crazy to think they can make them reusable.
But even if they can't get them reusable, I think it would be a great advance if they can just make them 1/4 or even 1/2 the cost. I don't think Musk started SpaceX because he thought it was the best way to make money. He probably did it in part for the fun of it, but I think primarily he's truly driven to make it cheaper. Falcon 1 has proven Musk a capable entrepreneur. I hope so much that he can get Falcon 9 into orbit.

Jon Goff is a great rocketry blogger. He pushes the orbital propellant depot hard and this is why. Once you have it going, it boosts the capabilities of your launch infrastructure considerably. Since you no longer have to launch fuel with lunar missions, you can fit a lot more vehicle on smaller rockets. The Ariane 5 is another rocket that can carry an unfueled Orion or propellant. Another important aspect is that this approach is highly scalable. You can use the same tricks to fuel other big missions, manned or not. It's a shame that NASA has done almost nothing with this concept.

It would be a natural continuation in the sequence of engine designs they've done. My take is that they're focusing on launching falcon 9 right now. They need that to go well. But there's no reason they couldn't have bigger engines on the drawing board.
The failures of the N1 were more related to lack of sufficient funding, poor quality control and lack of any test stands (The first time the N1 fired it's 30 engines was during its first flight attempt). There was nothing inherently flawed in the approach they Soviet's took, it's just that the engineers were forced to do it on the cheap The first flight failed due to the engine control system shutting down all engines on the first stage after a problem was detected with one of the engines (an engine fire). Second flight was almost the same problem, except one of the first state engines exploded after it ingested a wrench that someone left in the fuel line. During the third flight an unexpected interaction between the engine thrust and prevailing winds resulted in a roll that exceeded the command authority of the rocket and it broke up. The Last flight almost successfully completed it's first stage burn, but a few seconds before shutdown the N1 was designed to shutdown 6 engines to keep thrust within design limits. The shutdown resulted in unexpected pressure transients, the fuel lines ruptured and the vehicle broke up.
I am more interested in seeing if they recover this rocket. IIRC, they have not been able to recover the falcon I's. I am surprised that they do not choose to launch several more 1's and get the recovery correct. But have to make the 2010 deadline.
On a side note, I do wish that he would pull in a partner or two and get the escape tower built. It would be nice to see human rated by the time the shuttle is over.
I prefer the "u" in honour as it seems to be missing these days.
32 chambers, not engines. Not the same thing.
