Manned Mission To An Asteroid: Eureka Moment Or Dead End?

With the shuttle program behind us and International Space Station construction now complete, we begin a new era in space exploration. The long-sought foothold in space that Station provides has finally been established, and it serves as our jump off point from low Earth orbit to all points beyond. More than that, it stands as the corner stone of a new orbiting infrastructure that will be needed for any course we choose to undertake next.

The choice of our next destination sets in motion the many cogs and wheels that make up the much larger machine of space exploration. It is with great care then that we must consider the direction in which we set off before that machine gains momentum. We’ve already seen the cost of breaking that momentum: the $9 billion that went into the now cancelled Constellation program, for instance; squandered money that could have gone a long way towards moving mankind out into space on a sustainable path. The original Vision for Space Exploration embodied in the Constellation program underwent too many changes, too many course corrections. By the time of its demise, Constellation bore little resemblance to the program initially set in motion under the O’Keefe leadership of the early to mid two thousands. This sad fact underscores the importance of staying the course.

Where should we go next? The answer to that question must address the sustainability of space exploration. Anything less is to repeat the mistakes of the past. Sustainability means infrastructure, which can be thought of in much the same terms as we think of infrastructure here on Earth: roads; bridges; airports; utilities; communications; waste disposal; shipping, emergency services, etc. The list goes on. There is an entire infrastructure that will be needed in space to support a human presence there, long term. The International Space Station – aside from its function as an orbiting laboratory – is the first baby step in that direction. Where we pick to go into space next must foster and support the emergence of infrastructure. The logic is inescapable. Just as inescapable are the economics. That’s why when we speak of building infrastructure, we’re necessarily going to be limited to the area close to home: Earth orbit; cislunar space or the space between the highest Earth orbit and the moon; and the lunar surface itself.

The Obama Administration’s vision for space exploration is to send NASA astronauts to an asteroid, purportedly as the means to save civilization in the event one was discovered to be on a collision course with Earth. Exactly what humans would do once there hasn’t been worked out. Without any means to carry out its objective, the plan is vague and without substance. At the outset, it conspicuously fails to address the important issues we’ve just laid out.

First, a mission to re-route an asteroid does not need humans. Such an endeavor can be effectively carried out with robotic spacecraft. The methods proposed, ranging from firing nuclear bombs to focusing light beams on a menacing asteroid, do not require or use astronauts.

Its secondary mission is to serve as a stepping stone for future missions to Mars, but an asteroid is very different from a planet and thus requires different technologies. Tools such as jetpacks, tethers, bungees, nets and spiderwebs to allow explorers to float just above the surface of an asteroid while attached to a smaller mini-spaceship are all redundant to the ultimate missions the administration claims they support.

When we consider these facts in the light of day, the Obama plan begins to appear frivolous; more a stunt than serious exploration. An asteroid is no more than the cosmic analog to an iceberg. Yet plans are being drafted to send astronauts there on a mission that would not advance a human presence in space in any way, whatsoever, beyond the hand full of individuals making the trip. Can you imagine figures of history having committed the same folly?

Since the dawn of the space age it was the civil space program alone to amalgamate our drive for exploration beyond Earth. But things are changing and evolving. The private sector is stepping in to shoulder some of the loads traditionally carried by the government like building and operating rockets to low Earth orbit. Of course the private sector has partnered with the space agency from the beginning, so what’s different today? Though most commercial entities – the larger ones in particular – still prefer the safety of the more traditional public-private partnership in which the government assumes all the risk, a few bold entrepreneurs have stepped up and taken a seat at the table. They are seeding the development of space systems and vehicles using their own private capital. Founder of Paypal Elon Musk, cofounder of id Software John Carmack who made such computer games as Doom, Sir Richard Branson who founded the Virgin conglomerate, founder of Budget Suites of America Robert Bigelow, founder, president and CEO of Amazon Jeff Bezos, and Microsoft cofounder Paul Alan are among the most notable people to invest hundreds of millions in the aggregate so far.

Those investments were and continue to be anything but a safe bet. The men and women investing their fortunes and reputations in the very risky business of human space flight know that they stand to lose it all, yet they continue despite that risk. Why? Because the dream of exploration, the yearning to set out for parts unknown, is not the sole domain of NASA. All the passion and the scientific and engineering talent for which the space agency has come to be known exists in spades in the private sector.

There is something, however, that sets the private sector apart from the government; something that we take as a tacit to the urge for space travel, yet has never been part of NASA’s charter. That something is the impulse to colonize and see everyone benefit from the limitless resources and opportunities of space.

We often assume that it is the role of NASA to colonize space since so much of what they do can lead to that end, but that assumption is entirely false. The agency’s function is that of research and development of new space technologies. That those technologies either could or should be used for the colonization of space lies completely outside their purview. It may be at some future time that their charter is amended to include colonization, but for now, it is strictly R&D.

Even without a mandate for colonization, the government still has the obligation to set clearly defined goals that advance sustained human access to space. Not only does the Administration’s mission to send NASA astronauts to an asteroid fail to meet this requirement, it fails even to justify the stated reasons for carrying out the plan. Indeed it smacks of not-invented-here: a malady that would seem to afflict Washington with each successive administration.

The market forces that drive business are fortunately very different from those of politics. If a company were to radically change course every 4 years as so often happens inside the Beltway, it would not remain in business for long. The instability and indecision our government has displayed over the past 10 years in matters of space have resulted in its current languor. Without a change of leadership , the government cannot be relied upon to pursue the obvious course that scientific discoveries on the moon have brought to light, so it is likely that private enterprise will have to rise to the occasion.


A New Dawn Arising

As far back through antiquity as Aristotle it was theorized that the physical world in which we live is made up of atoms. And though the ancients’ mastery of deductive reasoning led them to great leaps of enlightenment, it was not enough to accurately describe reality. “Close, but no cigar,” as they say. Complete atomic theories forged in the fires of rigorous scientific examination would have to wait more than two millennia.

The modern scientific method is, in simplest terms, a three-step process: observe; theorize; and test. It’s proven to be a very successful way of discovering nature’s secrets, but the process is far from finished when theories have passed this stage. They must withstand rigorous scientific debate and challenges, in which peers from throughout the discipline examine every aspect of the experiment from the data to the underlying mathematics and finally to the conclusions. Not until it has survived this intense scrutiny can we embrace a theory and allow it to be taken as a law.

Albert Einstein, whose theories of the macroscopic world have revolutionized our understanding of time and gravity and Werner Heisenberg, one of the founders of quantum mechanics, had some of the most heated debates in scientific history over their theories. Challenges – even angry and passionate – among piers in science form a necessary fixture in its discourse and one that we relax at our own peril.

Today the peer review process serves us well as an absolutely essential part of science. Because our understanding of the universe is built in layers, with one set of laws building upon earlier ones iteratively, imagine the consequences of discovering that something we’ve taken as a fundamental law is flawed, or worse, false. Such an event would be catastrophic, so the importance of remaining diligent with peer review cannot be over stated.

Yet as strong as this process tends to be, there are those rare times when it breaks down. After all, it is a human endeavor, and humans are fallible, so when a breakdown does occur, the wise man pauses to understand why and how. He endeavors to prevent it from ever happening again.

We see just such a break down occurring in recent history following the Apollo lunar flights of the late 1960s and early 1970s when samples of rocks were returned from the moon and examined by scores of scientists. When the lunar dust settled and the papers had all been published, the scientific world proclaimed that the moon was more arid than the driest desert on earth.

That’s the way things stood for four decades: a kind of lunar science dark ages in which notions of returning to the moon, of building upon those gains so hard won at the expense of much national treasure and three astronaut’s lives, would be bluntly dismissed. Aside from the fact that the political goals behind the missions – sadly, their biggest driver – had been achieved, it simply made no scientific sense to return. Mankind was beginning to cast an eye around the solar system for a place where he could explore and perhaps settle. Any serious consideration of where next to go would necessarily have to include the concept of ISRU, or in-situ resource utilization. It’s what early pioneers called living off the land, and the idea behind it is simple. Exploration must be carried out with attention to its costs, which are kept at a minimum when consumables and materiel can be found and used at your destination. Each pound carried with the expedition costs money, so the less you take with you, the smaller the cost and the more exploration can be accomplished and made sustainable. With water being one of the most important and costly resources of any expedition, and with the lunar surface having been found utterly devoid of it, the moon was unceremoniously written off. Our nearest neighbor in space, what many call the eighth content, was now considered a dead end.

Just as the dark ages on Earth were followed by the Renaissance, the lunar dark age has given way to a enlightenment. 2009 saw new, robotic missions sent to the moon. They carried state-of-the-art instruments and beamed down to Earth volumes of new data to be examined by a fresh eyes. Within months, those science teams were sending out an electrifying discoveries that would send shock waves across the world. Water! Water had been discovered trapped in the permanently shadowed craters of the lunar South pole! More analysis revealed that the entire moon is covered in a thin veneer of water deposited by the solar wind, making it a renewable source.

The really big shocker was yet to come. A Brown University freshman! by the name of Thomas Weinreich published a paper in a May, 2011 edition of the journal Science in which he announced the results of a study he had recently conducted on 40-year-old rock samples from the moon. And his findings? Water! It had been there all along.

Only five years before, Alberto Saal, a professor at Brown, and some collaborators had applied to NASA to look for water in Apollo rocks. Colleagues laughed at his obvious naiveté.

How is it that so many brilliant minds could have concluded with such certainty for so long that the moon was utterly arid? Two words: Group Think. According to the Merriam-Webster Dictionary, Group Think is “a pattern of thought characterized by self-deception, forced manufacture of consent, and conformity to group values and ethics.” This is precisely the reason behind our long-lived ignorance of water on the moon. Those early assertions that no water existed in lunar rock samples should have been challenged and would have had it not been for the very the arrogance that Dr. Saal encountered. It was Group Think that effectively shut down the peer-review process for decades.

As a new dawn arises on lunar science and we again look towards the moon as our next home away from Earth and source of natural resources and new opportunities, it’s important that we weigh and consider the aftermath of a certain pitfall in the human psyche. What it cost us was 40 years and an entire generation of would-be astronauts and pioneers left orphaned when Apollo was ended. We cannot allow this to happen again, so it behooves us to scan our horizons – and those hidden places right under our noses – for signs that scientific consent is being manufactured. Can you think of any? Perhaps a theory on how the Earth traps and releases energy? Could there be a theory out there in which it is proclaimed that the time for debate has passed on a science that is “settled”?

Think about it.


Former Senator Schmitt Advocates A National Energy Plan As Constitutionally Mandated

February 16, 2011 by · Leave a Comment

The constitutional mandate for a rational, scientific, and economically sound national energy plan lies in its close modern relationship to the constitutionally mandated “common Defence”.  Dependence on foreign sources of oil, and therefore transportation fuels, limits both near and long-term national security options. That dependence also creates an economic burden to our economy that restricts the liberty of Americans and their 9th Amendment guarantee of the pursuit of happiness.

Dependence on imported oil removes the defensive and foreign policy leverage needed to prevent attacks by terrorist states.  Imports subsidize the financial supporters of terrorism. Dependence has the further effect of giving the United States no influence over the price it pays for oil.  If the price of oil came under the direct economic influence of the United States, for example, Iran would have great difficulty affording the development of nuclear weapons and their delivery systems.

Dependence on oil and gasoline imports also gives China further means to intimidate our national leaders into acquiescence to its continuing ambition for international dominance.  China’s rapidly growing economy has a major influence on world energy supply and cost, competing directly with our needs.  Cold War II has begun; however, it is being fought on an economic and energy front as well as on a military deterrence front.  On this point, China’s rapidly developing space capabilities and its expressed interest in lunar helium-3 energy resources cannot be ignored.

Many varied elements are necessary to a long-range plan that would ultimately provide for energy independence and a more stable economy.  A scientifically and economically based, long-range plan also would provide far more benefit to the preservation of the environment and natural resources than possible today.

In the near term, Congress must take back the control of regulatory laws it has transferred to the Executive Branch, particularly those rules that prevent attaining energy independence from commercially viable natural energy resources.  Closely tied to independence are the facilities necessary to refine domestic crude oil into gasoline, diesel, and jet fuel.  The One House Legislative Veto described previously in these essays [link] constitutes a constitutional means for the Congress to control rule making delegated to the Executive.

President Obama’s continuing statements and restrictive actions notwithstanding, the only commercially viable natural resource that currently offers an unsubsidized path to independence from imported oil is domestically accessible crude oil along with the domestic refineries necessary to create fuel oil, diesel, gasoline, and jet fuel.  Natural gas offers some potential to reduce imports; however, the use of tax credits or direct subsidies of the initial capital costs for fleet or aircraft conversions to natural gas, or even personal automobile conversions, should come with payback provisions as those  conversions realize long-term economies.

To fully understand the potential and challenges of gaining near-term energy independence, industry, national, and state policy makers require a more complete understanding of the potential resources of oil and natural gas available beneath public lands and in off-shore areas.  A rapid, cooperative industry-federal-state scientific assessment of those potential resources would provide the knowledge necessary to evaluate the private investments and national enabling policies necessary to achieve and maintain independence.

Research and technology development aimed at future commercially viable alternative portable fuels should focus on the following: coal liquids, ethanol from nonfood crops, and algal bio-diesel, and water-derived hydrogen from catalytic systems energized by the sun or by waste heat from needed power plants. Significant historical and current technological progress has been made with regard to these fuels; however, commercial viability must include production costs low enough to enable the creation of convenient and cost-effective fuel delivery infrastructures.  Battery-based systems do not constitute a viable, broadly applicable alternative portable drive system due to their very low, coal- or uranium-to-power-train total efficiency, as well as their charging inconvenience.

Major solar energy systems such a large-scale wind and solar electric plants are far from being competitive without major subsidies from taxpayers or ratepayers.  For these systems to have any hope of being practical contributors to the national energy mix, a significant technology development effort must be undertaken by industry. Due to the great competitive gulf between these systems and standard coal and nuclear systems, it is questionable if the federal government should be funding a new round of technology development.  Many more critical energy initiatives require urgent attention.

Other essays in this series [links] have made the scientific case that climate change largely results from natural phenomenon and that attempts to reduce the very small human induced component to such change will have little practical effect.  At the same time, misguided political efforts to control climate change unconstitutionally restrict the liberties of Americans.  On the other hand, even if not persuaded by the scientific evidence against human-caused climate change, the replacement of end-of-life coal-fired power plants with advanced nuclear plants constitutes the best of all economic and environmental worlds.  The first step in such replacement should be the reform and streamlining of regulations governing nuclear plant construction.  If that is done, and the time necessary to construct plants is halved, investment capital will follow the demand without any need for loan guarantees or subsidies.

At the same time as America should be moving toward nuclear power as the source of most of its electricity, the effort to find underground repositories for the burial of spent nuclear fuel rods should be abandoned. Monitored, retrievable, above ground storage makes much more sense in the long-term.  Future reprocessing of these rods will provide additional fuel for electrical power generation as well as numerous useful isotopes for medical and industrial applications.  The actual useless waste, that is, the much reduced, left over high-level radioisotopes, ultimately can be changed (transmuted) into stable isotopes or easily confined short-lived radioisotopes.

Reprocessing of nuclear fuel rods and transmutation of the remaining high-level radioactive waste will require significant new investment by industry if allowed by federal authorities.  Although defense-related spent fuel rods are currently reprocessed, and France reprocesses their civil reactor fuels, commercial reprocessing development in the United States was terminated by the Carter Administration.  It should be restarted, immediately. Transmutation of actual waste from reprocessing can be done most efficiently by exposure of radioisotopes to energetic protons produced by helium-3 fusion systems.  Until reprocessing and transmutation technologies have been developed to a commercial level of readiness, above ground, spent fuel rod storage is the most practical solution to this contentious issue.

In the longer term, the development of modular nuclear breeder systems, high temperature gas reactors, thorium-fueled reactors, and lunar helium-3 fusion should be part of the mix of systems examined by robust research and technology development programs. Government, industry, and academia should be mobilized into joint technology development efforts not unlike those that made American aeronautics the envy of the world in the 20th Century. Unfortunately, inherent scientific, engineering, capital costs, and waste disposal issues mean that the billions spent on pursuing tritium-fueled fusion will not succeed in developing a commercially viable fusion power system.

A central underlying issue in the implementation of a defense-oriented national energy plan continues to be the lack of both objectivity and quality in the American educational system [links].  From beginning to end, most young people now miss both the essential foundations of history, constitutional government, and science and mathematics necessary to participate in the implementation of such a plan. No energy plan, much less our national defense can be successful unless the States begin to fully live up to their 10th Amendment responsibilities in education.  As during the height of World War II and the Cold War, the Federal Government only should be a non-controlling partner in the funding of those elements of science and engineering education essential to the “common Defence” but no more than this if liberty is to be preserved.

Previous Congresses and Administrations have not upheld their constitutional mandate to “provide for the common Defence” relative to energy and instead have used politically motivated legislation and regulation to prevent the private sector from providing for the nation’s critical energy needs.  This neglect has led to a national security crisis through progressively increased dependence on foreign sources of oil as well as other strategic resources.  The Constitution requires that there be a concerted and immediate federal focus on energy independence.  This is not what the Founders would have desired, but past neglect means no choice remains other than capitulation to the economic and military intimidation of the enemies of liberty.
