Tag: Kline Directive

Our interstellar challenge is, how do we as a planet confined humans, become an interstellar species? This encompasses all human endeavors, and is vitally dependent upon interstellar propulsion physics to realize our coming of age as an interstellar species.

There are so many competing ideas on how to realize interstellar propulsion. These include chemical rockets, ion propulsion, nuclear engines, solar sails, atomic bomb pulse detonation, antimatter drives, small black holes, warp drives and much more.

How do we sift through all these competing ideas?

For his objectivity and courage in stating that mathematics has become so sophisticated that it can now be used to prove anything, I have named the approach to solving this interstellar challenge the Kline Directive, in honor of the late Prof. Morris Kline.

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, and to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts, (1) Legal Standing, (2) Safety Awareness, (3) Economic Viability, (4) Theoretical-Empirical Relationship and (5) Technological Feasibility.

Legal Standing: Do we have the protection of the law?

Mr. Gregory W. Nemitz of The Eros Project is the first person I know, who pushed the limits of the law. As a US taxpayer, Nemitz claimed ownership of Asteroid 433, Eros, and invoiced NASA $20,000 for parking and storage of the NEAR Shoemaker spacecraft. Citing faulty interpretation of the Outer Space Treaty of 1967, NASA refused to pay. On April 26, 2004 U.S. District Court Judge Howard McKibben dismissed the case. We have to address this. What is to stop other governments from imposing taxes on our outer space commercial activities that is “for the benefit and in the interests of all countries”?

Safety Awareness: Can we protect our crew and our planet?

In the heady rush to propose ideas for new propulsions systems or star drives it is very easy to overlook safety considerations. Quoting E.J. Opik, “Is Interstellar Travel Possible?” Irish Astronomical Journal, Vol 6, page 299. “The exhaust power of the antimatter rocket would equal the solar energy power received by the earth — all in gamma rays”. And Opik quotes the eminent Carl Sagan, Planet. Space Sci., pp. 485–498, 1963, “So the problem is not to shield the payload, the problem is to shield the earth”.

Economic Viability: Can realistic commercial viability be determined?

Space exploration economic viability is not an accounting problem that can be solved by CFOs and accountants. This economic viability is a physics and engineering problem. For example, chemical rocket propulsion to Alpha Centauri, our nearest star, would cost about $1.19x10^14 or 23x 2011 world GDP.

Theoretical-Empirical Relationship: Is the hypothesis empirically sustainable?

String theories are a good example of a theoretical-empirical relationship that is yet to be proved. Let’s remember Prof. Morris Kline’s words when theorist claim a velocity of 1032 x c (velocity of light) is achievable. Don’t get me wrong. Mathematics is vital to the progress of the sciences, but it needs to be tempered with real world experimental evidence, otherwise it is just conjecture, and ties up our search for interstellar propulsion technologies.

The reverse is equally valid. Without the theoretical underpinnings, there will not be much experimental progress. Podkletnov’s gravity shielding experiments are a good example. In 2 decades since Podkletnov published his experiments, there has not been any experimental progress. My inference is that none of the proposed theoretical explanations addressed all the observations and therefore, could not guide future experiments.

Technological Feasibility: Does it work?

Technological feasibility in a realistic and finite time frame is vital. Technological feasibility quickly leads back to the question of commercial viability. Developing future feasible technologies is an iterative process between technological feasibility and commercial viability, until we can reach the stars without having to ask the question, whom do we select to leave Earth?

Applying the Kline Directive, a quick method of eliminating competing technologies is to construct the Interstellar Challenge Matrix that compares the pros and cons of each competing propulsion technology.

Can we hasten the development of interstellar propulsion technologies? Yes.

Since disproving the validity of Alcubierre-type warp drives, interstellar propulsion physics is currently non-existent. To birth this propulsion physics, in 2012, I classified physical hypotheses/theories into 3 categories (1) Type 1: The Millennium Theories, (2) Type 2: The 100-Year Theories and (3) Type 3: The Engineering Feasible Theories.

Type 1, Millennium Theories require more than a 100 years and maybe up to 1,000 years to prove or disprove. Mathematically correct but inscrutable with physically verifiable experiments, even in the distant future. String and quantum gravity theories fall into this category. Why? If we cannot even figure out how to engineer-modify 4-dimensional spacetime, how are we going to engineer-modify a 5-, 6-, 9-, 11- or 23-dimensional universe?

Type 2, 100-Year Theories show promise of being verified with technologies that would require several decades to engineer, test and validate, and do not lend themselves to an immediate engineering solution. The engineering solution is theoretically feasible but a working experiment or technology is some decades away as the experimental or physical implementation is not fully understood.

Type 3, Engineering Feasible Theories lend themselves to engineering solutions, today. They are falsifiable today, with our current engineering technologies, if one knows what to test for and how to test for these experimental observations.

We as a society need to apply the Kline Directive to invent new propulsion physics theories, that are at best Engineering Feasible and at worst 100-Year theories.

We now have the tools to quickly eliminate both theoretical and experimental proposals that are highly likely to be unproductive, and focus on those that truly have potential of delivering commercial interstellar propulsion technologies. In the US money is no object, as the combined 2015 DARPA and NSF budgets, is $10.26 billion. Allocating a very small slice of these budgets for propulsion physics would be an enormous step forward.

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts:

1. Legal Standing. 2. Safety Awareness. 3. Economic Viability. 4. Theoretical-Empirical Relationship. 5. Technological Feasibility.

In this post I will explore Safety Awareness.

In the heady rush to propose academically acceptable ideas about new propulsions systems or star drives it is very easy to overlook safety considerations. The eminent cosmologist Carl Sagan said it best “So the problem is not to shield the payload, the problem is to shield the earth” (Planet. Space Sci., pp. 485 – 498, 1963)

It is perfectly acceptable if not warranted to propose these technologically infeasible star drives based on antimatter and exotic matter, as academic exercises because we need to understand what is possible and why. However, we need to inform the public of the safety issues when doing so.

I do not understand how any physicist or propulsion engineer, in his/her right mind, not qualify their academic exercise in antimatter propulsion or star drive with a statement similar to Carl Saga’s. At the very least it gets someone else thinking about those safety problems, and we can arrive at a solution sooner, if one exists.

We note that the distinguished Carl Sagan did not shy away from safety issues. He was mindful of the consequences and is an example of someone pushing the limits of safety awareness in the spirit of the Kline Directive, to explore issues which others would (could?) not.

We have to ask ourselves, how did we regress? From Sagan’s let us consider all ancillary issues, to our current let us ignore all ancillary issues. The inference I am forced to come to is that Carl Sagan was a one-man team, while the rest of us lesser beings need to come together as multi-person teams to stay on track, to achieve interstellar travel.

In interstellar & interplanetary space there are two parts to safety, radiation shielding and projectile shielding. Radiation shielding is about shielding from x-ray and gamma rays. Projectile shielding is about protection from physical damage caused by small particle collisions.

I may be wrong but I haven’t come across anyone even attempting to address either problems. I’ve heard of strategies such as using very strong electric fields or even of using millions of tons of metal shielding but these are not realistic. I’ve even heard of the need to address these issues but nothing more.

Safety is a big issue that has not been addressed. So how are we going to solve this? What do we need to explore that others have not? What do we need to seek that others would not? What do we need to change, that others dare not?

To achieve interstellar travel, the Kline Directive instructs us to be bold, to explore what others have not, to seek what others will not, to change what others dare not. To extend the boundaries of our knowledge, to advocate new methods, techniques and research, to sponsor change not status quo, on 5 fronts:

1. Legal Standing. 2. Safety Awareness. 3. Economic Viability. 4. Theoretical-Empirical Relationship. 5. Technological Feasibility.

In this post I will explore Legal Standing.

With respect to space exploration, the first person I know of who pushed the limits of the law is Mr. Gregory W. Nemitz of The Eros Project. He started this project in March 2000. As a US taxpayer, Nemitz made the claim that he is the Owner of Asteroid 433, Eros, and published his claim about 11 months prior to NASA landing its “NEAR Shoemaker” spacecraft on this asteroid.

Within a few days of the NEAR Shoemaker spacecraft landing on his property, Nemitz sent an invoice for twenty dollars to NASA, for parking and storage fees at twenty cents per year, payable in one century installments.

Citing faulty interpretation of the Outer Space Treaty of 1967, NASA refused to pay the fees required by Nemitz. This issue then proceeded to court. Unfortunately, on April 26, 2004 U.S. District Court Judge Howard McKibben Ordered the case to be dismissed.

The moral of this real story is that you don’t have to be a high flying physicist, planetary geologist, astrobiologist or propulsion engineer to advocate &/or sponsor interstellar travel initiatives. You could even be a retired coastguard, and miraculous things might happen.

Congratulations Gregory Nemitz for trying something nobody else dared to do in the spirit of the Kline Directive.

Planetary Resources, Inc. whose founders are Eric Anderson and Peter H. Diamandis could possibly provide the second challenge to space law. How? The “treaty also states that the exploration of outer space shall be done to benefit all countries” … you see where I’m going with asteroid mining?

I’m not an attorney, but these are things we need to watch for. In the light of Planetary Resources objectives and activities Nemitz’s parking fee case poses some dilemmas. First, if the US Government will not stand up for its citizens or entities, what is to stop other governments from imposing taxes for mining what is “to benefit all countries”?

Unfriendly governments will be quick to realize that they have nothing to lose and everything to gain by pursuing such claims in international courts, and through UN organizations.

Second, the judicial system could not intervene because, were it to agree, then everyone would have a claim to outer space property without investing in their claim. That would be like saying John Doe, during the gold rush of the 1840s & 1850s, could claim half of California but had no intention to exercise his mining rights.

Everything hinges on what one could consider an ‘investing’. The Homestead Acts of 1862 to 1909 would be a useful analog. These Acts gave an applicant ownership at no cost of farmland called a “homestead” to anyone who had never taken up arms against the U.S. government, had to be 21 or older or the head of a family, live on the land for five years, and show evidence of having made improvements.

So what would an interplanetary equivalent be? You, the reader could propose your version. Here is a first pass at it. There are two parts:

1. Asteroids: An applicant may claim ownership to an asteroid, provided the claimant had never taken up arms against the U.S. government, and can exercise the claim by placing a token of claimant’s ownership on the claimed asteroid within 1,000 Earth days or equivalent, of submitting the claim. Upon placing the token on the asteroid, the claimant is then given 2,000 Earth days or equivalent, to show evidence of having developed the commercial value of the asteroid.

Failure to comply will cause the claim to be null & void and return the asteroid to the public for future applicants to claim the property.

2. Planetary Resources: An applicant may claim ownership of up to 25 km2 of planetary surface, and the mineral & water rights within the area, provided the claimant had never taken up arms against the U.S. government, and can exercise the claim by placing a token of claimant’s ownership on the claimed planetary surface within 1,000 Earth days or equivalent, of submitting the claim. Upon placing the token on the planetary surface, the claimant is then given 2,000 Earth days or equivalent, to show evidence of having developed the commercial value of this planetary surface.

Failure to comply will cause the claim to be null & void and return the planetary surface to the public for future applicants to claim the property.

In the case of gaseous planets like Jupiter, the claim shall be limited to 25 km3 at specified altitudes, longitudes, and latitutes.

Planetary Resources, Inc. I wish you the best.
