Models Versus Reality

Jon Goff has been doing yeoman’s work in digging into the ESAS appendices. I’ve done a lot of this kind of architecture trade, and it is indeed extremely sensitive to assumptions. And from just this excerpt, while I haven’t read it myself (I can’t find the time from my day job, and I’m glad that Jon did), it sure looks like the game was rigged (which isn’t at all shocking in the context of all of the problems that have arisen). I was simultaneously saddened and amused by this:

I know that Mike Griffin was claiming that part of the reason for doing Ares-I was to teach NASA how to design launch vehicles again, and I guess we have documented proof of the need.

Seriously though, this is a common rookie mistake. You don’t go basing decisions worth tens of billions of dollars on an unvalidated design tool. Now, this isn’t saying that INTROS is a useless tool, just that it obviously doesn’t capture all the state of the art in stage design, and until it does, its results ought to be taken with the appropriate sized (apparently multi-ton) grain of salt.

Well, apparently NASA does exactly that. Or at least it pretends to base them on it. I don’t think that they’re going to pull the wool over Norm’s eyes, though.

British (Or Canadian?) Firefox

I like the spell chequer in Firefox, but I’ve noticed that it doesn’t understand American spelling. On the previous post, it told me that “defense” was spelled incorrectly, and suggested “defence” instead. I’ve also seen it tell me that “favorite” is properly spelled “favourite.” Anyone know why?

Amusingly, I also note that it doesn’t think that “firefox” is a word.

Not Good Enough

There’s an old saying attributed to Voltaire that “the perfect is the enemy of the good.” There are multiple interpretations of this aphorism, but one of them is that one must often accept the achievable, even if flawed, in preference to the perfect but unachievable solution.

Many defenders of Constellation use this argument, saying that if it’s not the best architecture, it’s good enough, and the only one politically feasible at this time, and that any other solution will only cause further delay. Implicit in this argument, of course, are the assumptions that further delay is unacceptable and that it is indeed good enough. Clark Lindsey points out an amusing analogy that Roger Pielke came up with in response to a similar argument by Paul Krugman that current plans for cap and trade are good enough — “Get on the bus.”

I don’t think that Ares is quite as bad as the idea of jumping the Grand Canyon with a Greyhound, but I do think it a vast waste of money, if our goal is space accomplishment rather than keeping parking lots full in Huntsville. From this space enthusiast’s perspective, it is not only imperfect, but it’s not even good enough. Even in the unlikely event that it is successful by NASA’s own cost and schedule criteria, it will be a disaster from the standpoint of making us space faring, flying far too little for far too much money per flight. The goals of the Aldridge Commission were good ones, and as currently planned, it contributes little to nothing to achieving them. As I wrote Sunday, if we need some additional delay to get it right, then we should do that, if it’s at all possible. And if it’s not possible, then we should just give up on having a useful and affordable space program, because this plan is so far from one that I certainly don’t want any more of my tax dollars spent on it.

[Update a few minutes later]

The goals of the Augustine review have been posted on the federal register:

The Committee should aim to identify and characterize a range of options that spans the reasonable possibilities for continuation of U.S. human space flight activities beyond retirement of the Space Shuttle. The identification and characterization of these options should address the following objectives: (a) Expediting a new U.S. capability to support utilization of the International Space Station (ISS); (b) supporting missions to the Moon and other destinations beyond low Earth orbit (LEO); (c) stimulating commercial space flight capability; and (d) fitting within the current budget profile for NASA exploration activities.

I can think of many architectures that would do a good job of those four goals, but Constellation isn’t one of them. It really only supports goal (b), and even that not very well. As Clark says, it will be both sad and amusing to watch NASA’s attempts to explain how it does.

Journalism, Then And Now

I think, sadly, that Mickey is right:

I had a revealing argument with a politically sophisticated friend–call him “Max”– when the “game changer” charge first surfaced. Max’s argument: Suppose it were a scandal sufficiently big to sink Obama. Any red-blooded Times reporter would be proud to publish it and tack Obama’s scalp to the wall. To have taken down a presidential nominee–that would be a professional achievement, maybe a Pulitzer. They’d be high-fiving in the newsroom.

I think my friend is right about the culture of the newsroom–about 45 years ago. As for today, I think he’s living in a dreamworld. Even if the Times had published such a story, Times reporters would certainly not have high-fived the colleague who’d cost Obama the election. Not after two terms of Bush. And I have no faith the paper would even have published it (before allowing the reporter to slink out of the building). In part, that’s because I have no faith that I’d publish it. The old adversarial ethic–I play my role and let the system take care of the moral consequences–rightly went mostly out the window with the ascension of the Sixties cohort.

Yes, the cohort that thinks it won the Vietnam war (not the one to keep South Vietnam to go communist, but rather the one at home against the Amerikkkan fascist pigs who thought that not going communist was a good idea). And now they work to make sure that America never again wins a war, and that people who favor free minds and free markets never win elections.

Lileks Versus Mastercard

…and creeping, creepy ecofascism:

Isn’t it interesting how Dad looks like the sort of delayed-adolescent types most likely to be already concerned about these things, and spending his day working on developing websites for sustainability, hosted on servers powered by methane captured from pig excreta? For that matter, who would like this ad? Wives who regard their husbands as overgrown boys in need of the Moral Guidance of those who will inherit the earth, perhaps…

…One more thing: if the kid didn’t learn these steps to righteousness at home, where did he get them?

The state knows best.

Where’s My Flying Car?

And what happened to my space colonies?

Yes, it was never a mass movement, and even with the merger of NSI and L-5, I don’t think that NSS has ever had more than a hundred thousand members. I do think, though, that it is sufficiently appealing to a sufficient number of people that when we break out of the NASA paradigm, and the supply actually responds to demand, some people will live in space in the future.

[Evening update]

Clark Lindsey responds to Dwayne Day’s dyspeptic space colony post:

In the 1970s space had become a niche topic little noticed by the general public. Within that niche area one could search around and find a tiny sub-niche dealing with in-space orbital space colonies. Sure, there were the occasional articles and a handful of books about O’Neill space colonies and a small group of people had a high interest in them. However, you could say the same thing about a million other topics as well. Orbital space colonies never came close to being a topic that most people were aware of, much less considered in any thoughtful way.

If in 1980 you asked a randomly selected group of a thousand people what they thought about space, a thousand would say, probably in the first sentence, that space was wildly expensive. If you asked them if they had read an article about space colonies in the past decade, I doubt even fifty would say yes. And most of those fifty would say such colonies might be a great idea but are impractical while space travel is so wildly expensive.

Yes, as is the case of much of space policy, it’s all about information and perspective. (I’ve added “Media Criticism” to the categories for this post, and bumped it…)
