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."
If nano-technology reaches the point where we can program assemblers to take local materials and build structures from electronic plans, what are the implications to space travel?
Imagine, for instance, if someone could take a box of Rocketbuilders out to an island somewhere and deploy it, then sit back as the nanocites build a metal extraction plant, extracted the materials it could get from the sand/ground, built pipes into the sea to process metals that are there, etc. It'd build a gantry, then assemble a rocket from specs and finally fuel it from hydrogen and oxygen cracked from the water.
An open source rocket would be a neat, easy way to get a good start for a project to create the instructions for these assemblers. I figured the big open source project when this technology came onto the scene would be digitizing and CAM'ing the specs for, say, the Saturn V (moon rocket). Make it easy enough to grow these launchers, and folks could launch prefabbed housing and supplies no problem. Just find the right spot, maybe rent an acre of seafront property with no downrange population, and go for it.
Sure, it's fantasy at this point, but who knows? This is a shot across the bow for folks that are inevitably going to say "This is a stupid idea. What use is an open source rocket if you aren't a huge government or company with a bajillion dollars/euros/rubles to spend?".
Sure, maybe the reward isn't obvious now, but what about sometime in the near future?
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...
The part that NASA is (purportedly, I haven't seen the contracts / specs yet) making open is the avionics architecture, the control computers, attitude and position sensors (GPS, Inertial navigation gyros, etc), and the software and physical network interconnects.
This isn't the rocket motors or physical stages. They want people to be able to propose upgraded computer systems, gyros, GPS units, etc. without having to rebuild the whole guidance system from scratch. So you make it modular, you use a technology like Avionics Full-Duplex Ethernet as the networking PHY and Datalink layers, you specify a realtime IP stack and the higher level protocols to use for transmitting status and position and control codes, etc.
Having to maintain 40-year-old computer and navigation equipment designs for the Space Shuttle has made everyone open to the idea of modular, upgradable, scalable, etc...
