Investment­s in space pay off

A little more money for NASA could launch new industries

- Stephen Sandford is systems engineerin­g director for Stinger Ghaffarian Technologi­es Inc., where he works on a range of space challenges, from asteroid utilizatio­n to space policy. He spent 28 years as an engineer and researcher at NASA.

The tax bill just passed by Congress and signed by President Donald Trump has big wishes attached to it. Supporters claim it will boost the economy by 5 percent a year. Most economists and nonpartisa­n tax groups put that rate closer to half a percent to a percent, while increasing annual deficits by $1 trillion over a decade.

While I’m no economist — I’m a space engineer — I can show a far more cost-effective way to ensure brisk growth for the nation’s economy, not just in the next decade but the next generation. We’ve tried it before, and it has exceeded nearly everyone’s expectatio­ns. Actually, it has been tried twice: once when Europeans settled the American frontier and again when, in a single decade, we put men on the moon and brought them back safely.

A new economic booster would combine the two ideas. It would settle a frontier, and it would entail an ambitious public-private program in outer space.

The most common arguments against a publicly funded space program are that we can’t afford it and that private industry, led by the likes of Elon Musk and Jeff Bezos, are handling space perfectly well on their own, thank you.

But let’s look at the last time we spent a significan­t portion of the federal budget on space — the 4 percent devoted to NASA during the Apollo program in the 1960s and early ‘70s.

Look at the American economy before, during and after Apollo, and you can see a correlatio­n between economic growth and a robust aerospace program. During the 1950s, gross domestic product grew by 26 percent (from $2.27 trillion to $3.06 trillion in inflationa­djusted 2009 dollars, according tothe U.S. Bureau of Economic Analysis.) During the 1960s — the decade of Apollo — GDP grew by 35 percent ($3.08 trillion to $4.72 trillion). During the 1970s, GDP grew by 28 percent ($4.71 trillion to $6.5 trillion).

In other words, the American economy grew onethird faster during the Apollo decade than during the decades before and after.

Of course, no economist would say that the space program caused this growth. Still, the “knowledge ore” of science and technology generated by the Apollo program and NASA R&D continues to provide spinoffs today.

The total cost of Apollo in current dollars was $109 billion, or 0.2 percent of GDP, a slice equaling one-500th. Were the economic benefits worth that cost? You decide.

In addition to the direct economic benefits of a fully funded public space program, space exploratio­n inspires young people to go into STEM fields (science, technology, engineerin­g and mathematic­s), which are vital to innovation and long-term economic growth.

Annual cost of American education: $810 billion.

Approximat­e cost of STEM education: $400 billion.

Additional cost of expanding STEM expenditur­es by one-half: $200 billion.

Additional cost of expanding NASA’s budget by onehalf: Only $10 billion. Then there is space’s value in enhancing America’s internatio­nal standing. Assuming that the value of something is what you are willing to pay for it, we can look at relative costs.

Annual federal expenditur­es on internatio­nal affairs (the department­s of State, Defense, Energy and Veterans Affairs): $800 billion.

Annual NASA budget: A mere $18 billion.

Finally, we can look at how much of an impact the public space program has on the overall federal budget.

Size of 2015 federal budget: $3.7 trillion. NASA’s share of the federal budget: 0.4 percent. Impact to the federal budget of fully funding NASA: An additional 0.3 percent.

Still, some people say the money would be better spent on feeding and housing the poor, or on medical research, or on non-space research and technology. In fact, the federal government spends far more on these programs already.

Annual federal housing assistance: $190 billion, according to the Center on Budget and Policy Priorities. Annual budget of the Supplement­al Nutrition Assistance Program (SNAP): $75 billion (same source). National Institutes of Health budget: $31 billion, according to the NIH. Federal R&D expenditur­es: $145 billion, according to the American Associatio­n for the Advancemen­t of Science.

Can we afford space? The numbers seem to show that we can; the impact of fully funding NASA to meet all of its congressio­nally mandated missions is minimal — almost undetectab­le in the federal budget.

All right, if space is such a good investment, why not leave it to private investors? Economist Mariana Mazzucato argues that publicly funded missions help turn economic uncertaint­y into calculable risk. Ms. Mazzucato likes to describe the investment world as a landscape; a “bumpy and complex one,” as she puts it. Government’s job — when government is visionary and well run and not dogmatical­ly following Keynesian or libertaria­n ideology — is to get out ahead and smooth the way. NASA and other agencies invest in new mission-oriented technology “until fear-inducing uncertaint­y” gradually levels into “mere risk.” Economists argue about the difference between uncertaint­y and risk, but as an engineer and physicist, I like to use numbers to distinguis­h between the two. Risk has numbers. Uncertaint­y lacks them.

Take extraterre­strial mining, a future industry in which entreprene­urs will extract minerals from the Moon and asteroids. Astronomer­s have calculated the net worth of some single asteroids — the value of their contents minus the cost of retrieving them — to be in the billions of dollars. A great many highly intelligen­t, well-informed people are working up plans for the industry right now. The only problem is, the industry won’t exist for at least another two decades. Even five years requires a vast amount of patience for a venture capitalist. And VCs tend to invest at a relatively safe moment in the life cycle of a company, after a market exists and industry is defined.

Many startups face a dangerous time when they have burned through most of their capital and have not yet begun to earn significan­t income. Techies, economists and investors call this phase the Valley of Death. Most big investors wait for companies to get through the valley, proving their business models.

New industries have not even reached the Valley of Death. When the brilliant physicist Richard Feynman first conceived of the field of nanotechno­logy in the 1950s, for example, the term “nanotechno­logy” had not even been coined.

The nanotech industry now is getting off the ground, with nanomateri­als a billionth of a meter thick being employed in sunscreens and carbon-fiber bicycle components, among other uses. But the industry remains in its infancy, and the far-out, science-fiction-worthy products — nanorobots repairing patients’ organs, clothing that can change color and shape — will require a lot of investment with unknowable financial risks.

That is why the U.S. government created the National Nanotechno­logy Initiative in 2001, with an investment totaling $21 billion through 2015 and continuing today. An effort combining universiti­es, private companies and government agencies (including NASA), the initiative works to create a trove of knowledge ore and pass it to all players in the private sector, all while helping train a workforce skilled in the new industry.

Extraterre­strial mining and nanotech are two examples that speak to Ms. Mazzucato’s assertion that the government “often takes the lead, not only to fix markets but to create them.” She notes that it took venture capitalist­s 15 to 20 years to invest in biotechnol­ogy and the internet, after the fields had been launched with government support.

While economists express serious doubt about the ability of tax cuts to stimulate the economy without shackling the next generation with debt, a public investment in settling the frontier between Earth and Mars ultimately will see far higher returns at far less cost. Where’s the proof? Apollo: The last time we made a serious, sustained effort in space.

To fully fund NASA simply to meet the missions Congress already has mandated would cost an additional $12 billion to $13 billion a year. That relatively tiny investment would be enough to settle the frontier and cross the entreprene­urial Valley of Death.

While economists express serious doubt about the ability of tax cuts to stimulate the economy without shackling the next generation with debt, a public investment in settling the frontier between Earth and Mars ultimately will see far higher returns at far less cost.
