NASA Ares Rocket Specs to Be Open Source
Bruce writes "As a step toward returning to the moon, NASA announced last week that Boeing will be the lead contractor for the Ares I rocket. Interestingly, Popular Mechanics reports that the system's specifications will be 'open-source and non-proprietary' to encourage competition on future contracts."
CAPCOM: Good morning Persues, how are you today?
PERSUES: 5 by 5 Houston, what's the plan for today? We're only halfway to the moon.
CAPCOM: Persues, we need you to run a few 'patch' commands, we're uploading the diffs now...
No folly is more costly than the folly of intolerant idealism. - Winston Churchill
Not the same as open source for software. They will make the data available only to future bidders and only when it benefits the government. You're not going to download rocket technology off of NASA's website.

But will the wrist strap on the rocket be strong enough? I don't want my Ares Rocket messing up my flat screen TV

For mass-produced products, which is what we'd like rockets to become, the cost of the design the parts is relatively minor. So giving away the design does give away that much. Instead, it's the design of the manufacturing systems that determines how cheap and reliably we can make the thing. Cars are cheap because they have almost no labor (most cars take less than 40 labor-hours to build). And what make a Pentium so valuable is not the design layout of the transistors, but the $1 billion fab that can reliably etch all those transistors on a wafer of silicon.
More than a new rocket design, we need a new rocket manufacturing technology that cranks out high quality rockets for very little per each additional rocket.
Two wrongs don't make a right, but three lefts do.
ITAR restricts technology related to satellites and launch vehicles to a select group of individuals and prevents export to other countries without a lot of hassle. If it is open source, how are they going to prevent other nations from getting the plans to these "weapons"?

What seems cool about "open source" relative to this project is that it may make the specifications much more solid in all areas (any interested engineer can spot problems or suggest enhancements, not just NASA paid engineers, but at the same time I doubt that all of the rocket specs CAN be fully open sourced, because if you can put a rocket into space with sufficient accuracy to put a manned craft into lunar orbit, you can also put a warhead on that same rocket and plop it with decent accuracy anywhere in the world.
Which, given the rogue elements in our world and a number of fairly rich folks willing to fund the rogues, is, as you might surmise, NOT A GOOD THING.
...Open Source isn't the only answer -- but it's almost always a better value than the alternatives...
Don't be silly. As has been pointed out in the past, if you want to design a rocket for military strikes using a Lunar rocket design is an ABSURD way to proceed. The payload requirements are absurd overkill, as is the support infrastructure.
Now, if you want to worry that the technology itself might be adapted to weapons, I point out certain political realities.
1. Anyone stupid enough to launch a rocket at the US or other modern nation is toast. Missles can be tracked back to the origin, and the origin will shortly thereafter be reduced to some rather fundamental particles.
2. Anyone wanting to deliver a doomsday suicide nuclear payload or other payload would do MUCH better at MUCH cheaper prices to smuggle it into a port city or across the border. If they're capable of engineering such an attack they can figure that out - and we have no missle to trace back to the origin. Not to mention we can't shoot it down...
The only concern that I might buy would be China or some other large country we're worried about having to fight on a large scale getting access to modern tech they don't currently have. However, most of what they need to figure it out themselves they already have thanks to loads upon loads of outsourcing and buildup of their own economy and academic brainpower. They're trying their own moon shots already, remember? And one of the founding members of their program we chased out of OUR country.
If you want to limit rocket building potential, you'll have to limit everyone else's access to smart people. Otherwise you'll eventually face the problem anyway, after imposing a lot of pain on your own smart people to no particular purpose.
The summary also says that Boeing will be the prime contractor for the Ares 1. This is not true. The article is about Boeing being the prime contractor for the avionics. Incidentally, Boeing is also the prime contractor for the second stage structure. However, the first stage is being built by Alliant Techsystems (who also makes the nearly identical shuttle SRB's...that part of the contract was a shoe-in), the 2nd stage engine is being built by Pratt and Whitney, and the Orion spacecraft that the Ares is being designed to launch is contracted to Lockheed Martin.
