Since the dawn of the space age, both proponents and opponents of the manned space program have used the “spinoff” argument to buttress their respective cases.

Many fans of Apollo, and Shuttle, and the International Space Station, and whatever the NASA manned space program happens to be doing at the time, make grandiose claims about the many benefits showered upon our nation because we sent a few people to the Moon, or into orbit.

Without NASA and Apollo, they contend, our nation wouldn’t have been blessed with the bounty of microchips, or personal computers, or electro-encephalograms, or teflon, or Tang and freeze-dried ice cream, or camping refrigerators, or indoor plumbing, or sliced bread in the grocery store.

NASA itself uses this argument, and publishes a magazine titled (not coincidentally), Spinoff.

Many of these claims are hyperbolic. Most of them are false.

Consider a couple of the more serious ones regularly put forth from the above list. Microelectronics was driven by missile technology and the need to get warheads and ICBMs smaller, long before Apollo was a gleam in Kennedy’s eye. Teflon was invented by Dupont in 1938, two decades prior to NASA’s founding.

Unfortunately, proponents have to rely on such overhyped claims, because the actual benefits of our manned space program have been relatively sparse, compared to the national treasure invested in it over the past four decades.

Their opposite number, those who oppose manned space, often do the same thing from the other direction. If NASA cheerleaders overstate the benefits, many opponents of NASA (and technology in general, and western values) see it, just as mistakenly, as one of the roots of militaristic evil.

Since its inception, many have confused the civilian manned space program with a nefarious military plot to take over the heavens.

It’s somewhat understandable, for several reasons.

Many people are unknowledgable about space programs in general, and this is particularly true of those viscerally opposed to military activities. In the 1960s, those opposed to the US military were unable to make such fine distinctions, since they were generally not opposed to just military activities, but technology in general, and any government spending that wasn’t perceived as good for “children and other living things” (i.e., Great Society welfare programs).

Thus, many assume that there is no division between America’s military and civilian space programs (which was in fact the case in the former Soviet Union), and that the former are in fact derived from the latter. I saw such confusion just this week on my weblog, in which someone claimed that ICBMs were developed from manned launch vehicles, when in fact, just the opposite was the case (we would not have been able to get to the Moon by 1969 had we not been able to piggyback on the earlier development of ballistic missiles).

In addition, because the Apollo program was a bloodless and surrogate battle in our Cold War against the Soviet Union, it became a symbol of national defense, even though Dwight Eisenhower took great pains, and even slowed the program down, to ensure that it was explicitly performed by a civilian (not military) space agency. This cultivation of a civilian NASA image wasn’t helped by the fact that the first astronauts were all military test and fighter pilots.

So it shouldn’t be surprising that the Arab News believes (or at least, claims to believe) that “the technology that the Americans have already used against Iraq and more recently against Serbia and then Afghanistan was a direct spinoff of the hugely expensive NASA space program.”

This is, after all, a publication that is just barely moored to reality in the first place. It would apparently be comfortable in continuing to falsely describe the Israeli actions in Jenin this past spring as a “massacre,” and to endorse as fact the “Protocols of the Elders of Zion,” a nineteenth-century fictional slander of the Jews.

NASA’s current manned space program is neither the cornucopia of technology advertised by its supporters, or the evil quasi-military government plot against which its detractors solemnly, or hysterically, warn us. It’s simply a relic of the Cold War that lives on through habit, and institutional inertia.

It offers inspiration to some, providing the rhetorical fig leaf that allows it, in Congressional debates, to continue to be funded every year for its real purpose, which is to maintain jobs in certain key Congressional districts and support foreign policy goals. At a fraction of a percent of the federal budget, it’s affordable for that purpose, and it doesn’t matter very much if it doesn’t do very much, as long as there’s a flight occasionally to make it look as though it’s doing something.

Certainly there is some spinoff technology benefit from the program–it’s impossible to engage in any high-tech endeavor without occasionally coming up with serendipitous results. And of course, there’s occasionally some cross fertilization with military space activities (though from a taxpayer standpoint, disappointly little). But neither of these facts is reason, in itself, to either support or oppose it.

Proponents need to come up with real goals, and real reasons, that can resonate with the American people–something difficult to do with the program as currently planned, in which we spend billions for a Motel 6 in space that can support only half a dozen people, even if current plans come to fruition.

Opponents need to get their facts in order, and come up with good reasons to end it (and perhaps replace it with something more useful for getting humanity off the planet). The manned space program has, so far, been very lucky in its enemies.

India announced this week the long-term goal of sending men to the Moon. I guess that answers the question of who will be running the motels and Kwik-E-Marts there…

Seriously, though, I wish them well, and hope they do. And in light of such events, both sides need to address the real issues, so that we can have an intelligent debate on our own nation’s future in space.

Thanks to Gary Hudson (who is upset with all of the liberties that Peter Jackson took with the second book), for tipping me off to this.

Hey, it’s not the way I remember the book, but it’s been a long time since I last read it.

He assumed that the speed of gravity (the speed at which gravity waves travel, and can thus affect other bodies) was the same as the speed of light, but until recently, it hadn’t been actually measured. Now it has.

I was bothered by the following grafs, though.

Fomalout and Kopeikin said their results are accurate within about 20 percent.

Knowing the precise speed of gravity is important to physicists testing such modern ideas as the superstring, which holds that fundamental particles in the universe are made up of small vibrating loops or strings. It also affects some basic space-time theories.

There is a difference between accuracy and precision. Accuracy means that it’s in the ballpark, while precision indicates that we can measure the value to a large number of decimal places. It’s possible to be accurate, and not precise, and to be precise, and uttely inaccurate (i.e., precisely wrong). As an example, if I said that the speed of light was 1.3578456457746456456 meters per second, I would be giving an extremely precise answer, that wasn’t within six orders of magnitude of the correct answer.

Results that are accurate within only twenty percent are hardly precise, and in fact, don’t provide full confidence that the speed of light is indeed the speed of gravity.

We can never know that for sure, of course, no matter how precisely we measure. It might be that the speed of gravity is exactly 99.99999999999% of the speed of light, rather than equal to it, and we may never know, for sure. Similarly, the exponent in the universal law of gravitation might actually be 2.00000000000000000000000000001 rather than exactly two (so it’s not exactly a function of the distance between the bodies squared), but Occam’s Razor indicates that that’s pretty unlikely, particularly since there are sound theoretical and geometric reasons to think that it’s truly a squared law (having to do with the nature of spherical fields).

Similarly, if the two speeds are measured to be within twenty percent, it’s likely that they’re truly the same (particularly since there’s no reason to think they’re not), and the likelihood will increase as we get better measurements, with less error.

It could be a new frontier in blogging. I think that when Glenn gets his vlog going, he should offer a morning exercise program. Instead of letting his exercise interfere with blogging, he could integrate it in. He could discuss the topics of the day between crunches and situps.

It might be a little rough to get up that early in the morning for those of us on the left coast, but I’d be willing to give it a go.

For now, he should just expand on his diet and routine in the blog, so we can all try it, too. He could even put out an Instant cookbook of favorite recipes for that blogger on the go.

That’s the headline of this ABC news story. They write it apparently with no sense of irony, despite the fact that, early on, it contains this quote from the former New York governor:

“Class warfare? He declared the war,” Cuomo said at the National Press Club. “He said, ‘We’re going to give all the money to the rich.'”

Cuomo, who is pushing the Democratic Party to sharpen its difference with the Republicans on issues such as tax cuts, declared: “We’re not the ones who started the war. We’re just defending ourselves against his attack.”

He said, “We’re going to give all the money to the rich.” Yup, I’ll be that’s just what he said.

The evil Republicans are pulling a reverse Robin Hood. They’re going to round up all the peasants, turn them over and shake all the pennies out of their pockets, and hand the ill-gotten swag over to the rich. All of it.

It couldn’t possibly be that the President is simply letting the “rich,” who pay most of the income taxes, keep a little more of their own money.

And of course, rather than attempting to put Cuomo’s immoderate demogoguery in any kind of rational context, they instead attempt to buttress it, with this:

That cut gives 52 percent of its benefits to the richest 1 percent of Americans by 2010 those with an average income of $1.5 million according to the labor-funded advocacy group Citizens for Tax Justice.

Citizens for Tax Justice. It’s a non-profit, and it has such a nice name. Who could object to “justice”? They couldn’t possibly have an axe to grind.

Glad there’s no liberal media bias–just think what the story might have said if there were…
