Falcon 9 Is Now Fully Integrated At Cape Canaveral 82
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."

The R-7 rocket and its descendants the the Russians developed was designed to be assembled on its side because it was easier to assemble the final rocket that way. The only downside to this method is you need big and heavy rigs to move the rocket to the vertical launch position (if you've seen the launch pads at the Baikanour cosmodrome they have a lot of erecting machinery at the launch pad to move the rocket to the vertical position).
That's why for the Saturn V rocket, NASA decided to assemble the rocket vertically, but that needed a very large building to do this, hence the very tall Vertical Assembly Building (VAB) not only to accommodate the height of the rocket but the overhead cranes to lift the various rocket components.

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.

You're about 20 years behind, there. The big lesson of the Space Shuttle is that reusability isn't the holy grail we thought it would be.
In some cases, recycling makes sense. But sometimes, a reuseable spacecraft is as bad an idea as a reuseable condom -- and for pretty much the same reasons.

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.

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.

In fact, since Falcon 9 heavy can lose one or more turbopumps and keep going, a failure mode that would doom a Soyuz, you could claim that Falcon might be *more* reliable.

Interesting Question (Score:4, Interesting)
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?
Re:Interesting Question (Score:4, Informative)
Oh, no, the shuttle did take advantage of the weight. It's just not hundreds of tons. And they needed to make the tank even lighter to send the ISS up.
I suspect the big reason why the shuttle tank's paint took up so much weight is that the paint is going on rough insulation, not a slick metal skin. And the tank is also fairly huge, given it holds liquid hydrogen.
So I suspect that the weight cost for painting something like the Falcon 9 isn't nearly as bad, given it's an aluminum skin. And there may be some engineering reasons too.

In addition to the factors already mentioned:
Extra weight on a spacecraft is more problematic the longer the weight sticks around during launch, because the faster the extra weight ends up going, the more energy (i.e. fuel) is needed to accelerate it -- and the more fuel is needed to accelerate that fuel, and so on.
The shuttle external tank is carried almost all the way to orbit. Every pound of weight saved on the tank is roughly equal to an extra pound of payload, so leaving it unpainted makes a lot of sense.
But the Falcon 9 rocket's fancy paint job is on its first stage. This drops off long before orbit is reached, so it doesn't impact the cargo capacity nearly as much.
