False Choice

William Broad stenographs NASA in this New York Times article, in which a false dichotomy is set up.

For its next generation of space vehicles, NASA has decided to abandon the design principles that went into the aging space shuttle, agency officials and private experts say.

Instead, they say, the new vehicles will rearrange the shuttle’s components into a safer, more powerful family of traditional rockets.

Note the implication here–there are only two ways to build rockets into space. One can use the design principles that went into the Shuttle, or one can go back to the design principles that we used in the past–you know, “traditional” rockets.

[Cue Tevye: “Tradition………Tradition!]

There’s little discussion of what the “design principles” of the Shuttle are that make it so bad, other than it’s allowed to have stuff fall on it during launch. And the “separating crew from cargo” myth prevails:

The plan would separate the jobs of hauling people and cargo into orbit and would put the payloads on top of the rockets – as far as possible from the dangers of firing engines and falling debris, which were responsible for the accidents that destroyed the shuttle Challenger in 1986 and the Columbia in 2003.

No explanation of why separating people and cargo makes people safer (because it doesn’t) or why we should care about losing people, but not payloads or launches that cost tens, or hundreds of millions of dollars.

And of course, there’s the standard confusion about launch system economics:

By making the rockets from shuttle parts, the new plan would draw on the shuttle’s existing network of thousands of contractors and technologies, in theory speeding its completion and lowering its price.

“The existing components offer us huge cost advantages as opposed to starting from a clean sheet of paper,” the new administrator of NASA, Michael D. Griffin, told reporters on Friday.

“Cost” and “price” seem to be used interchangeably here (as is often the case with government programs, since price is usually just cost plus a fixed percentage). And there’s no distinction between, or discussion of, development costs versus operational costs. Yes, if you’re going to develop a new heavy-lift launch vehicle, or even a new vehicle for the CEV, then using existing components will reduce development costs. But if those components are very costly to procure and operate, the operational costs will remain disastrously, and unsustainably high. When they say “lower price” and “cost advantages” they’re referring to development cost only. They’ve simply thrown in the towel, and given up on getting safe launch.

And of course, no major media piece would be complete without the obligatory quotes from John Pike and Alex Roland, who seem to have an honored place in every reporter’s rolodex, though neither of them really have any expertise in these matters.

John E. Pike, the director of GlobalSecurity.org, a private Washington research group on military and space topics, said he wondered how NASA could remain within its budget while continuing to pay billions of dollars for the shuttle and building a new generation of rockets and capsules.

Alex Roland, a former historian of the National Aeronautics and Space Administration who now teaches at Duke University and is a frequent critic of the space program, said the plan had “the aroma of a quick and dirty solution to a big problem.”

They always justify Roland’s inclusion in these things by saying he is a “former historian” for NASA. They never mention, though, that this was only for a brief period, over two decades ago, and he dealt with aeronautics, not space. But he’s a good gadfly, like Pike, and Robert Park, so of course we should care what he thinks.

And I love this bit:

“The shuttle is not a lemon,” Scott J. Horowitz, an aerospace engineer and former astronaut who helped develop the new plan, said in an interview. “It’s just too complicated. I know from flying it four times. It’s an amazing engineering feat. But there’s a better way.”

Dr. Horowitz was one of a small group of astronauts, shaken by the Columbia disaster, who took it upon themselves in 2003 to come up with a safer approach to exploring space. Their effort, conceived while they were in Lufkin, Tex., helping search for shuttle wreckage, became part of the NASA program to design a successor to the shuttle fleet.

Well, he’s a former astronaut. And an aerospace engineer. He has no axes to grind–he just wants a safer launch system, right?

That’s a useful introduction, I guess, but somehow, I wonder if it’s the whole story. Well, as it turns out, the real agenda starts to dribble out a little later:

“It’s safe, simple and soon,” said Dr. Horowitz, an industry executive since he left the astronaut corps in October. “And it should cost less money” than the shuttles. Their reusability over 100 missions was originally meant to slash expenses but the cost per flight ended up being roughly $1 billion.

Note the implication that Shuttle is expensive because it’s reusable (with the further implication that we shouldn’t build any more reusable vehicles).

Anyway, it’s “safe, simple and soon.” Who could ask for more?

But wait a minute. Haven’t we heard that phrase before?

Well, it does say he’s an industry executive. But what industry? What company?

Oh, here it is, tucked away toward the end of the article:

After leaving the astronaut corps, he went to work for the booster maker, ATK Thiokol, where he now leads the company’s effort to develop the new family of rockets.

Nope, no axes to grind there. Well, at least they did mention it, finally.

My problem with articles like this is that, as I noted above, they set up a false dichotomy. We have other choices than doing it on expendable launch vehicles with capsules, and doing it with an oversized airplane stuck to the side of expendable parts that are a major contributor to the costs, and shed parts onto the reusable portion. Shuttle didn’t have to be the way it is, and it’s not the platonic ideal of a reusable (or even partially reusable) launch system, that allows us to extrapolate its flaws to any conceivable space transport. It was a program that was compromised early in its development by the same need to save development costs that seem to be turning the latest plans into another budding disaster, at least from an operational cost standpoint.

But as long as reporters at the New York Times rely on technologically ignorant naysayers like John Pike and Alex Roland, and breathless industry boosters, we’re never going to have an intelligent discussion of the real alternatives.
