John Carmack, Rocket Boy

will_edit_for_food writes "Space Future has an interview with John Carmack (of Doom and Quake fame) about his new company Armadillo Aerospace and their plans to build a passenger-carrying vehicle for space tourism." Carmack's involvement with unconventional rocketry is well-known, but this interview offers a glimpse into the details of Armadillo's approach to the skies.

I wouldn't really want to fly into space on a vehicle that used duct tape as an integral part of the craft. Even if these guys can build something capable of propelling someone into space, I wouldn't want to actually be on it until the design had been worked out by real engineers.

      This attitude of people being "real" engineers, and others being perceived as garage tinkerers is not only arrogant and misguided, it is what holds non governmental spaceflight back.

      I've seen supposed "real"engineers, in fact some with degrees from Universities such as Oxford, and supposed space engineering backgrounds, blow up rocket motors through simple and avoidable mistakes. Then again, I've seen non engineers, working without much funding (the supposed garage tinkerers), build comparable rocket motors that quite literally blow the "real" engineers efforts away in terms of reliability and robustness.

      The difference, is those without the attitude, and without the government/big business mentality, seem to have a better overall grasp of how the systems go together, not always, but in my experience, generally enough that it is noticeable. There's also another facet those you refer to as garage tinkerers have that I tend to see missing in many "real" engineers in space related disciplines; it's called common sense.

      As for your duct tape remark, and your comment on real engineers working out designs. I take it you've never been in one of the older space capsules ? It's always so easy to be an armchair expert when you have the benefit of ignorance to back you up. I would not, if I were you, ever go inside a Vostok or a Soyuz capsule, because if your comments above are anything to go by, you'd have a fit.

      When I worked professionally in the space industry on a project in Russia, I was amazed at the simplicity of the early manned space capsules. Technology has moved on sufficiently now, that people such as John Carmack (who is far from a garage tinkerer) could develop a manned capsule to match those, of that I have no doubt.

      I can't wait until John Carmack gets something manned flying. It will be like DC-X all over again. All these nay saying supposed "real" engineers suddenly changing their tune and saying "well I thought it would work actually, but I didn't say anything". Yeah right.

      Armadillo Aerospace will succeed where others have failed, precisely because they don't have the attitude so prevalent in large aerospace engineering projects.

      Forget innovation. There's all the tech we need already worked. We need the economics to work out- launching a lot does wonders for the economics. Launch every day and twice on tuesdays and the costs come down- that's the big secret. That's why the Space Shuttle costs so much: they don't/can't launch enough.

      As another post has pointed out, originally, the likes of Apple and HP were garage start ups. I can deal with it, what's your issue ?

      You are lucky if you've never come across "real" engineers who do louse up. There seems to be this arrogance that many have, this air of superiority. That's not only an observation from me (I'm a physicist by background, and yes, I have worked on a number of space missions, I just choose not to have the air of superiority that many in the industry adopt towards the so called "garage tinkerers" - a term that does many a great dis-service), but by friends who are engineers and work in their spare time on what is sneeringly called garage tinkering on rocketry, who are equally sick of the arrogant attitude espoused by engineers who spend more time in front of monitors than actually bending metal.

      It's one thing to read books like Rocket Propulsion Elements, or Spacecraft Propulsion Analysis and Design, but it's a totally different exercise to get out there and test, like Armadillo Aerospace are doing.

      The one whose claims require significant evidence is you. If these "real" engineers you refer to are so good, what happened to the likes of X-33, the X-30 NASP etc ? Why have Mars missions loused up because of metric/imperial confusion ? Why didn't the release system on missions that failed have a very simple, very low gain transmission system to at least enable mission controllers to know whether heat shields or descent probes separated ? What about the louse up with the first launch of Ariane 5 ? Gosh, that's a lot of discipline and knowledge shown there. Yes, these are a minority rather than a majority, but it shows that stupidity is not a trait for "real" engineers or their acolytes to confer on anyone else.

      "Real" real engineering doesn't depend on wearing a suit and working for a large multinational aerospace conglomerate, and being able to run 6DOF sims on supercomputers, it depends on good engineering practice. That is not dependent on the size of the organisation, it could be any size organisation, it could be operating out of a large aerospace production line or a shed. What is important is approach.

      You may also benefit from reading up about the early development of rocketry. The early work was carried out frequently by people not quite as knowledgable as you think, but with a more open mind to trying things out, and more an emphasis on testing than pontificating, that's for sure. The level of discipline required then differed little if at all from that employed by many garage level groups today. I take it you have tested hardware yourself, haven't you ? You've been at a launch pad when something unexpected goes wrong and you have to do some hack to get the vehicle in the air ?

      Personally, I prefer the build a little, test a little, incremental engineering approach. It works for Armadillo, it works for the group I work with, it works for many other "garage" style groups, and small companies. And the longer some maintain an air of superiority, and that rocket engineering is all so hard and requires big aerospace engineering conglomerates and insecure people with bit attitude problems, the more stupid they will look when the smaller, nimbler groups make monkeys of them.

Although not an engineer by training (or really by nature) myself, I've worked closely with them and understand the ethos quite well. Tinkering isn't a marginal activity, it's the heart and soul of what it means to be an engineer. The lack of imagination that the skeptics are showing is incredible - is it so hard to believe that a bunch of guys in a warehouse could eventually (note that word) build a ship that takes men into space?

      This is why I was so excited when "Junkyard Wars" became popular - it glorifies the engineers (at least the mechanical ones) in a way that is clearly needed, based on the nudniks who disparage Armadillo's efforts.

      Go to Armadillo's web site and read some of their weekly reports on their progress - these guys are totally serious, and they know their stuff. What they don't know, they've learned, from the ground up - they started with very simple engines bolted to test racks, and they even dribbled peroxide onto various materials to test how they reacted (note to self: no leather shoes!). Along with the other small rocket companies, they're creating a new space culture that is unbelievably exciting - you watch, this is not a blip - more companies like this will spring up. This is the beginning of a whole new private space industry - at last the general public has the technology available to launch thing Very High. :)

      Why is it that Marxism/Communism can only exist when it is enforced in oppressive authoritarian dictatorships? Because human nature causes most people to think only of themselves, their immediate friends, family, and about two generations of children ahead.

      Exactly... Marxism/Communism is an unworkable system because it runs contradictory to human nature. Why not let the discussion end there? People are not programmed to show the same amount of concern for a complete stranger as they would a family member, or a friend. That's simply how we work.

      Also, don't fool yourself into believing that you, as a self-proclaimed socialist, are any different from a marxist. You're not. Individual rights are cast aside by socialists and marxists. Some would argue that it's a matter of degree. I make no distrinctions... You are either for, or against, individual rights. Once you cross the line, you've chosen, and that's where you are.

      You concede that Capitalism provides an excellent mechanism for balancing supply and demand, but you fail to recognize that it also seeks to minimize waste (In that it is more expensive to be wasteful, than not to be. Inefficiency is penalized in Capitamism, in the form of increased costs of production.). Take two companies providing an identical product, selling for an identical price as an example. Which of them will win out in the end? The one which can best utilize it's materials, minimizing the costs. They will be more profitable, and have the means to drive the other out of the marketplace.

      Getting back to human nature, which economic system allows people the highest degree of freedom? Which allows the individual the greatest amount of personal choice? Which economic system demands the least amount of sacrifice?

      I realize that from a detached perspective, such as that of a student engaged in scholarly pursuits, these questions seem somewhat less than noble, and that the "people must adjust their lifestyles for the greater good" position seems a perfectly reasonable stance. The reality is that only Capitalism respects the rights of the individual, and that "the greater good" is a myth used by those who seek power to influence those that are ruled.

      We have seen the devastating results of socialism/marxism in practice. It results in the mismanagement of resources, including both raw materials, the means of production, and the application of labor. There is never going to be a 5 year plan that can successfully anticipate the needs of the moment. While capitalism cannot predict those needs either, it is certainly far more dynamic in responding to those needs once they are revealed.

      Understand that the only "equality" that we should strive for is equality of opportunity. Beyond that, you'd like to see equality of outcome, and that is something that is never going to happen.

      We, as people, are not equal. Some people are smarter than others. Some are stronger. Some are faster. Some are more creative.

      These countless differences in people ensure that the various outcomes of our lives will vary tremendously. Capitalism allows people to make the best use of their individual, disparate talents, allowing us to be rewarded based on how useful our talents are to those seeking them. Beyond that, what else could be hoped for?

      With that as a backgound, socialist schemes don't hold much appeal. If I put my talents to good use, and I can afford better health care than someone else, should I not be entitled to it? Health care, just like anything else, is a limited resource. Shouldn't price determine the allocation of that resource just as it does in any other market?

      If not price, what else should be used? Need? Who determines the person in greater need? Is there a panel of experts? A single arbiter? Would there be a board of appeals? Is a street person more "needy" than someone that runs a company?

      If there is some central controlling authority, is there any way to ensure that their influence isn't bought? How can we prevent corruption, or the playing of favorites?

      You can't. It all comes back to the fact that socialism/communism is inherently unsuited to human nature. Life isn't fair, and people will never truly be equal. Capitalism makes the best of a bad situation, while allowing people the greatest amount of freedom, and opportunity, and for that reason, it is the best possible economic system for humankind.

      First, they are funded through taxes, which is a clever way of taking money from the people that are actually out there earning it, and giving it to those that aren't.

      Second, the programs simply don't work.

      Understand that there is a difference between welfare and unemployment. Unemployment is not taxpayer funded... It is paid by employers and employees (Paid by the employer, but the cost has a direct relation to the salaries that employees earn).

      Unemployment insurance does what you described above. It helps people get through while looking for work.

      Welfare, on the other hand, is not funded by the individuals that receive its assistance. You mention that some States have placed caps on welfare benefits. That represents a reform of the welfare system. It's a step in the right direction, and in the States where such a limitation exists, a greater percentage of the participants are able to get off the program, and become self-sufficient.

      That fact alone speaks volumes about the net-effect of Johnson's "War on Poverty." Government subsidies do more harm than good. Entitlement programs victimize the very people that they are intended to help.

      Earlier in America's history, there were no government entitlement programs. Instead, when a person or family needed help, they turned to friends, family, local charities, or other organizations in their community. Assistance came from people they knew, with names, and faces. There was a sense of obligation not only to return to self-sufficiency, but to repay the debt of gratitude in some way, because the help had come from the community.

      Today, assistance comes to the mailbox, or is directly deposited into a bank account. There is little shame in it. There is nobody to say "thank you" to, nor is there any reason to feel a sense of shame.

      I'll never forget watching a program like 60 minutes, or some such program, interviewing a person on public assistance. The lady was in Wisconsin, back when Tommy Thompson had just become Governor, and had implemented the 5 year welfare limitation. The lady was very angry... She actually referred to her benefits as her "salary," as though she had earned it. I have had a job since the age of 13. I worked all through high school, and all of my adult life. I cannot tell you how much it angered me to hear this lady upset that she was finally going to have to find a way to pay her own way through life.

      But I don't want to turn this into a diatribe about some lady in Wisconsin...

      All of the issues you raise untimately leave me flat because they are all forms of wealth redistribution. Welfare... National Health Care... Food Stamps... Blah, blah, blah...

      Nothing in this life is free. Someone is paying. I am perfectly willing to pay my own way through life. Further, if there's something that I want, or even something that I need, I have no right to demand that you, or anyone else pay for it. The moment I try, or have the government do my bidding, then I have forfeit my own property rights.

      Once you do that, you have mothing left. If you have no right to property, you have no freedom at all. Your labor can be seized... You can be conscripted into the military, or some other "publically worthwhile" cause. They can dictate what you read, or see, or listen to.

      The point is that once you allow government to cross the line, they can redefine the line repeatedly, whenever "the masses" demand it.

      That is the fundamental difference between a "Democracy" an a "Republic."

      In a Democracy, government can undertake any activity, so long as it has the support of the majority. It is, in essence, mob rule.

      In a Republic, there are limitations on what a government can undertake, no matter what popular opinion may be at the moment. A government has a Charter, and it may not exceed the limits of that charter.

      It is for that reason that a Republic is the only form of government worthy of consideration for a people that ascribe the rights theory.

      Now bringing it around to your questions about the environment, sure, I want my children to be able to grow up in a world with fresh air, and clean water, and I want that for their children as well.

      Does that mean that I think the only way to get there is by placing artificial limits on the quality of life for people in the United States, or anywhere else in the world? Of course not.

      The answer lies not in turning back the clock. It lies in making the breakthroughs that allow us to elevate the rest of the world to our standard of living, and do so in such a way as to ensure the long term survival of the species.

      It means ending the witch hunt against nuclear power, which remains the most efficient, and cleanest means of meeting our energy demands. It also means finding a better way to manage the waste that is produced. We need to begin testing the second generation of nuclear power... Why haven't we built a pebble-bed reactor? No possibility of melt-down... Dramatically reduced amount of waste material... Same amount of power output.

      These things should be popping up all over the place until we can find a safe way to harness fusion power.

      Also recognize that they age of oil is coming to a close. Fuel-cells will be taking off 10 years from now. They'll be fairly common 15 years from now.

      The problems we face environmentally have solutions. We need to refine the solutions that we've already uncovered, and we need to discover the solutions that yet remain. Don't hamstring humanity in the interim...

      It's very easy for the "have-nots" or the "have-lesses" to cry foul, and demand that first world nations abandon centuries of human progress. Our ancestors worked hard to provide the foundation upon which we stand. I don't think it's time to jump off.

    Is crossing the road illegal? It can be quite dangerous you know!

    Yes, it can be quite dangerous. And yes, it is illegal in many areas. It is called jaywalking. Crossing a busy intersection became a very dangerous activity, so some smart people got together and identified and marked areas on the road where people may cross the road with a mitigated risk. These areas are called 'crosswalks' (insert Dr. Evil finger quotes). A pedestrian in one of these 'crosswalks' (finger quotes) has the right of way, and motorists must yield to the pedestrian.

    Anyway, getting back to the original post. Yes, it is illegal to run off and launch a craft into sub-orbital space. Why? Because it is dangerous. What if some yahoo decided to launch his garage rocket from his backyard, which is located next to LAX (Los Angeles airport)? He could hit something or kill someone! Not a good idea.

    These rocket-heads have to acquire the appropriate permissions and clearances before firing off their garage rockets. At the least, I would assume that they need to get FAA clearance, which would involve providing them with a launch and flight plan. In addition, they would probably have to get clearance from the local authorities for both the launch and landing sites.
