Apollo Thoughts From The Economist

There will be many retrospectives this week on the half-century anniversary of Kennedy’s speech. Here’s one from The Economist, that reads like they’ve been reading me for a while:

To many Americans, neglecting human space flight this way looks like a sorry end to the glorious chapter Kennedy opened half a century ago. He set out to make America’s achievements in space an emblem of national greatness, and the project succeeded. Yet it did not escape the notice of critics even at the time that this entailed an irony. The Apollo programme, which was summoned into being in order to demonstrate the superiority of the free-market system, succeeded by mobilising vast public resources within a centralised bureaucracy under government direction. In other words, it mimicked aspects of the very command economy it was designed to repudiate.

Exactly. Well, not exactly. One of the reasons that they did it this way (as I pointed out in my recent debate with Bob Zubrin) was that it wasn’t intended to be a demonstration of the free-market system:

There was a reason that Apollo ended over forty years ago. It had accomplished its mission, which was not to go to the moon, but to demonstrate that democratic socialism was superior to totalitarian communism in terms of technological prowess, which it did when Apollo 8 flew around the moon in 1968, and the Soviets gave up and pretended they had never been racing.

In any event, few people have any conception of how much Apollo warped our perception of how to explore and develop space, because they have no other framework in which to think about it. But that will change over the next few years as private entities start to show how Americans do space in a more traditional American way.

The Great Space Debate

Bob Zubrin and I rhetorically duke it out over at Pajamas Media. This exchange actually occurred several weeks ago, but it was only published this weekend.

[Update a while later]

Unfortunately, since I went first, Bob got the last word, but that’s why I have a blog. I’ll note that I find it utterly bizarre that he sees no value in orbital propellant storage (today was the first time I’ve seen his final response). Does he really think that all missions to Mars will originate from the surface of the earth, forever more? I’ll note also that he vigorously kicks the stuffing out of a strawman with talk of the problems of the orbital mechanics. It sort of reminds me of the arguments that missile defense proopponents used to make in places like Scientific American, coming up with some ridiculous way of accomplishing the thing, pointing out how ridiculous it was, and implying that there are no sensible alternatives. He doesn’t even mention Lagrange points, which obviate most of the plane-change issues.

One other thing. I think that his ad hominem attack on Jeff Greason was both gratuitous and laughable. Does he really believe that a) no one else on the Augustine panel favored propellant depots and b) that the only reason Jeff supports them is because they provide a market for a vehicle that he might build some day? Really?

[Update a couple minutes later]

In rereading his final rebuttal, I notice that he didn’t respond to much of what I had to say, particularly with regard to ending Apollo and the difficulty of doing what he wants to do, and making long-term space plans in a representative republic — he just repeated the same things he always writes.

It’s A Mystery

Frank Morring has a story over at Aviation Week on Chris Chyba’s testimony to Congress, in which he pointed out the same cost analysis that I did the other day:

Chyba repeated his 2009 warning that NASA has not been able to develop one vehicle and fly another at the same time, given historic budget constraints. But he said NASA may be able to learn from SpaceX as it develops the heavy-lift launch vehicle Congress has ordered it to build for missions beyond LEO.

“The other thing that I think one would want to understand in some detail would be why would it be between four and 10 times more expensive for NASA to do this, especially at a time when one of the issues facing NASA now is how to develop the heavy-lift launch vehicle within the budget profile that the committee has given it,” Chyba said.

I suspect the question was somewhat rhetorical — he probably knows the answer. As far as Congress is concerned, high costs are a feature, not a bug, as long as they don’t get so high that the program dies. Because high costs means lots of jobs for their constituents that they can point to at election time. A more efficient commercial industry would probably create even more jobs, but they would be a lot less visible. And note that whether or not anything is actually accomplished is secondary, if it’s a concern at all. Did anyone in Congress ever complain that Constellation was behind schedule? Maybe, but I don’t recall it. There were no complaints about the program from the rocket scientists on the Hill until it got canceled.

On War

A book review, of an old book:

On War is shaped by Clausewitz’s encounter with the history and ideas of his times; it is also shaped by his experience in one of the first truly modern bureaucracies. (One of the achievements of Frederick the Great that so impressed contemporaries was the meticulous organization of the Prussian army and state.) The relationship of individual genius and vision to bureaucratic routine is a serious strategic problem in the modern world. The virtues that make a great military commander are, as Clausewitz notes, intensely personal: imagination and moral courage being perhaps the rarest and most valuable. These are perhaps the worst qualities for an aspiring bureaucrat to have.

There are desk generals and battle generals, and the unequal struggle between them is a recurring problem — and not just in military organizations. Desk generals excel in the arts of bureaucratic warfare, stick close to the conventional wisdom in all ways, and were brilliantly described in two unforgettable Gilbert and Sullivan songs: Modern Major General and The First Lord’s Song. In times of peace these timeserving mediocrities rise inexorably to the top; wars usually begin with a painful shakeout while the beribboned and bemedaled lunkheads demonstrate their hopeless incapacity at the true military art. Then and only then do the unclubbable and unconventional officers whose only virtue is their ability to somehow win battles gradually edge to the fore and the Grants and the Shermans elbow past the Popes and the McClellans.

In terms of space, NASA has been at peace since the late sixties, and hasn’t had the necessary crisis to bring forth the war-fighting generals, though the current budget crunch may make it happen. We’re starting to see some signs of it (e.g., Phil McAlister). The problem remains, though, that space isn’t important. Until it is, we won’t take it seriously.

What Is Av Leak Talking About?

OK, I’ve read this article three times now, and I can’t figure out how they came up with the headline they did. Here’s the lead graf, on which it seems to be based:

Private space companies probably can expect at least 44 paying passengers for trips to orbit in the next 10 years, NASA has told Congress, but the price per seat could be higher than the U.S. government already is paying for rides on Russia’s Soyuz capsule.

So one would expect, in reading the rest of the piece, to see some explanation of that, right? But I can find nothing whatsoever to support it, or even an attempt to do so. The rest of the article is about the recent report that NASA gave Congress on commercial markets for human spaceflight, which the article itself admits doesn’t discuss cost. So what is the basis for the headline and lede, which seem to have no purpose other than to spread Fear, Uncertainty and Doubt (FUD) about commercial crew?

Anyone? Anyone? Bueller?

Anyway, the story did have the effect of piquing my interest, so I went off to read the report. Right off the bat, I found this paragraph in the summary potentially quite disturbing:

NASA plans to follow an alternative business method that allows U.S. industry more design ownership of their space systems and requires those companies to invest private capital to complement Government funds. This is similar to the approach NASA is using for the commercial cargo effort. NASA plans to award competitive, pre-negotiated, milestone-based agreements that support the development, testing, and demonstration of multiple commercial crew systems with a fixed Government investment. NASA also plans to use a unique Government insight/oversight model featuring a core team of sustaining engineering and discipline experts who closely follow the development of the vehicles. Additionally, NASA plans to use tailored human rating requirements, standards, and processes, with NASA providing the final crew transportation system certification.

Emphasis mine.

While later in the report, it clarifies this to indicate that this will be the case only for NASA employees and NASA-sponsored participants, many who read only the summary will think that NASA will be certifying commercial crew vehicles. Words mean things, and we fought and won a battle six and a half years ago to avoid certification of commercial spaceflight (something that the FAA would do, were it to occur, not NASA) in favor of launch licensing and informed consent. It could be a very serious hindrance to the development of the industry if there is a popular perception that vehicles “certified” by NASA are “safe” and those not are not.

We remain at a phase of the industry in which there will have to be a range of safety levels and prices, to allow the market to work. Yes, NASA is extremely risk averse (largely because human spaceflight isn’t important), but there will be others with a much higher risk tolerance, and they shouldn’t be required to pay high prices for excessive “safety” just because NASA wants to overdo it. As George Nield told Congress recently, we need to accept the fact that we may lose people in opening a frontier. What was unjust about the Challenger and Columbia losses was not the deaths of the crews per se, but that they weren’t properly informed of the real risk, and so didn’t have the information needed to make a rational choice. This was particularly the case with Challenger and Christa McAuliffe, who surely didn’t think that the risk was as high as it was (a hundred in one or so chance of dying). She might still have accepted it and flown if she had known that, but she should have been given the choice.

We need to understand that the level of acceptable risk is subjective, not objective, and that if what NASA astronauts were doing was important, we’d accept a much higher risk than we do now. There are people who would be willing to fly on a Falcon 9/Dragon without a launch abort system, and NASA’s insistence on one shouldn’t prevent them from flying. I hope that someone, perhaps Congressman Rohrabacher or George Nield, will push back on this report as written, and make it very clear that NASA is not going to be in charge of industry safety.

Going on, I found this quote, from page 25, a useful and important point that many don’t seem to understand:

Figure 13 only shows NASA’s needs for commercial crew and cargo transportation during the assessment period. NASA has already purchased over 40 crew seats on the Russian Soyuz system for ISS crew transportation and rescue services at a cost of well over $1 billion. Had commercial crew transportation been available to NASA, those 40+ crew seats could have been purchased from U.S. aerospace companies. Additionally, every year that there is a delay in the availability of commercial crew transportation (either because of budget cuts or other delays), some of the seat opportunities shown in Figure 13 will be transferred to Russia for the purchase of even more Soyuz seats.

This doesn’t discuss costs, and still doesn’t clear up the point of the AvLeak article, but it does point out the problem with continued dithering. I’m not generally of a protectionist mindset, but I’m not very happy shipping money overseas to a country that is continuing to wage a Cold War on us when that money could instead be developing an American capability that could reduce costs. I don’t believe that Commercial Crew is going to cost more than our Soyuz purchases, but I would support it even if I did, because I think that it’s in the long-term interest of not only the nation, but of mankind to reduce costs to orbit.

Finally, along those lines, I want to quote the final appendix in full:

NASA recently conducted a predicted cost estimate of the Falcon 9 launch vehicle using the NASA-Air Force Cost Model (NAFCOM). NAFCOM is the primary cost estimating tool NASA uses to predict the costs for launch vehicles, crewed vehicles, planetary landers, rovers, and other flight hardware elements prior to the development of these systems.

NAFCOM is a parametric cost estimating tool with a historical database of over 130 NASA and Air Force space flight hardware projects. It has been developed and refined over the past 13 years with 10 releases providing increased accuracy, data content, and functionality. NAFCOM uses a number of technical inputs in the estimating process. These include mass of components, manufacturing methods, engineering management, test approach, integration complexity, and pre-development studies.

Another variable is the relationship between the Government and the contractor during development. At one end, NAFCOM can model an approach that incorporates a heavy involvement on the part of the Government, which is a more traditional approach for unique development efforts with advanced technology. At the other end, more commercial-like practices can be assumed for the cost estimate where the contractor has more responsibility during the development effort.

For the Falcon 9 analysis, NASA used NAFCOM to predict the development cost for the Falcon 9 launch vehicle using two methodologies:

1) Cost to develop Falcon 9 using traditional NASA approach, and

2) Cost using a more commercial development approach.

Under methodology #1, the cost model predicted that the Falcon 9 would cost $4.0 billion based on a traditional approach. Under methodology #2, NAFCOM predicted $1.7 billion when the inputs were adjusted to a more commercial development approach. Thus, the predicted the cost to develop the Falcon 9 if done by NASA would have been between $1.7 billion and $4.0 billion.

SpaceX has publicly indicated that the development cost for Falcon 9 launch vehicle was approximately $300 million. Additionally, approximately $90 million was spent developing the Falcon 1 launch vehicle which did contribute to some extent to the Falcon 9, for a total of $390 million. NASA has verified these costs.

It is difficult to determine exactly why the actual cost was so dramatically lower than the NAFCOM predictions. It could be any number of factors associated with the non-traditional public-private partnership under which the Falcon 9 was developed (e.g., fewer NASA processes, reduced oversight, and less overhead), or other factors not directly tied to the development approach. NASA is continuing to refine this analysis to better understand the differences.

Regardless of the specific factors, this analysis does indicate the potential for reducing space hardware development costs, given the appropriate conditions. It is these conditions that NASA hopes to replicate, to the extent appropriate and feasible, in the development of commercial crew transportation systems.

Again, emphasis mine. Shorter version: our cost models are busted, and we don’t know how to do cost estimation for this new generation of space development companies. But the costs are a lot lower than most people think, and very promising for the future.

Give Me A Better Representative

I went over to the beach in Manhattan Beach today, and met this guy running to replace Jane Harmon in a special election on Tuesday. I don’t know what his chances are — it’s a jungle primary with five Republicans, five Democrats, and several other parties. Anyone who gets a majority wins outright, but if no one does, then there will be a runoff in a couple months between the two highest vote getters. I suspect that long-time state Senator and Democrat Debra Bowen will likely win, or at least get in the runoff, with the win coming in the next race. But we’re headed for redistricting, under a relatively impartial process, so the district may become more competitive for Republicans (it used to be, back in the eighties), and this race is good practice for novice candidates like Eisele.
