Category: nuclear weapons

1. Thou shalt first guard the Earth and preserve humanity.

Impact deflection and survival colonies hold the moral high ground above all other calls on public funds.

2. Thou shalt go into space with heavy lift rockets with hydrogen upper stages and not go extinct.

The human race can only go in one of two directions; space or extinction- right now we are an endangered species.

3. Thou shalt use the power of the atom to live on other worlds.

Nuclear energy is to the space age as steam was to the industrial revolution; chemical propulsion is useless for interplanetary travel and there is no solar energy in the outer solar system.

4. Thou shalt use nuclear weapons to travel through space.

Physical matter can barely contain chemical reactions; the only way to effectively harness nuclear energy to propel spaceships is to avoid containment problems completely- with bombs.

5. Thou shalt gather ice on the Moon as a shield and travel outbound.

The Moon has water for the minimum 14 foot thick radiation shield and is a safe place to light off a bomb propulsion system; it is the starting gate.

6. Thou shalt spin thy spaceships and rings and hollow spheres to create gravity and thrive.

Humankind requires Earth gravity and radiation to travel for years through space; anything less is a guarantee of failure.

7. Thou shalt harvest the Sun on the Moon and use the energy to power the Earth and propel spaceships with mighty beams.

8. Thou shalt freeze without damage the old and sick and revive them when a cure is found; only an indefinite lifespan will allow humankind to combine and survive. Only with this reprieve can we sleep and reach the stars.

9. Thou shalt build solar power stations in space hundreds of miles in diameter and with this power manufacture small black holes for starship engines.

10. Thou shalt build artificial intellects and with these beings escape the death of the universe and resurrect all who have died, joining all minds on a new plane.

I continue to survey the available technology applicable to spaceflight and there is little change.

The remarkable near impact and NEO on the same day seems to fly in the face of the experts quoting a probability of such coincidence being low on the scale of millenium. A recent exchange on a blog has given me the idea that perhaps crude is better. A much faster approach to a nuclear propelled spaceship might be more appropriate.

Unknown to the public there is such a thing as unobtanium. It carries the country name of my birth; Americium.

A certain form of Americium is ideal for a type of nuclear solid fuel rocket. Called a Fission Fragment Rocket, it is straight out of a 1950’s movie with massive thrust at the limit of human G-tolerance. Such a rocket produces large amounts of irradiated material and cannot be fired inside, near, or at the Earth’s magnetic field. The Moon is the place to assemble, test, and launch any nuclear mission.

Such Fission Fragment propelled spacecraft would resemble the original Tsolkovsky space train with a several hundred foot long slender skeleton mounting these one shot Americium boosters. The turn of the century deaf school master continues to predict.

Each lamp-shade-spherical thruster has a programmed design balancing the length and thrust of the burn. After being expended the boosters use a small secondary system to send them into an appropriate direction and probably equipped with small sensor packages, using the hot irradiated shell for an RTG. The Frame that served as a car of the space train transforms into a pair of satellite panels. Being more an artist than an *engineer, I find the monoplane configuration pleasing to the eye as well as being functional. These dozens and eventually thousands of dual purpose boosters would help form a space warning net.

The front of the space train is a large plastic sphere partially filled filled with water sent up from the surface of a a Robotic Lunar Polar Base. The Spaceship would split apart on a tether to generate artificial gravity with the lessening booster mass balanced by varying lengths of tether with an intermediate reactor mass.

These piloted impact threat interceptors would be manned by the United Nations Space Defense Force. All the Nuclear Powers would be represented.…..well, most of them. They would be capable of “fast missions” lasting only a month or at the most two months. They would be launched from underground silos on the Moon to deliver a nuclear weapon package towards an impact threat at the highest possible velocity and so the fastest intercept time. These ships would come back on a ballistic course with all their boosters expended to be rescued by recovery craft from the Moon upon return to the vicinity of Earth.

The key to this scenario is Americium 242. It is extremely expensive stuff. The only alternative is Nuclear Pulse Propulsion (NPP). The problem with bomb propulsion is the need to have a humungous mass for the most efficient size of bomb to react with.

The Logic Tree then splits again with two designs of bomb propelled ship; the “Orion” and the “Medusa.” The Orion is the original design using a metal plate and shock absorbing system. The Medusa is essentially a giant woven alloy parachute and tether system that replaces the plate with a much lighter “mega-sail.” In one of the few cases where compromise might bear fruit- the huge spinning ufo type disc, thousands of feet across, would serve quite well to explore, colonize, and intercept impact threats. Such a ship would require a couple decades to begin manufacture on the Moon.

Americium boosters could be built on earth and inserted into lunar orbit with Human Rated Heavy Lift Vehicles (SLS) and a mission launched well within a ten-year apollo type plan. But the Americium Infrastructure has to be available as a first step.

Would any of my hundreds of faithful followers be willing to assist me in circulating a petition?

*Actually I am neither an artist or an engineer- just a wannabe pulp writer in the mold of Edgar Rice Burroughs.

I was recently accused on another blog of repeating a defeatist mantra.

My “mantra” has always been WE CAN GO NOW. The solutions are crystal clear to anyone who takes a survey of the available technology. What blinds people is their unwillingness to accept the cost of making it happen.
There is no cheap.

Paul Gilster comments on his blog Centauri Dreams, concerning Radiation, Alzheimer’s Disease and Fermi;

“Neurological damage from human missions to deep space — and the study goes no further than the relatively close Mars — would obviously affect our planning and create serious payload constraints given the need for what might have to be massive shielding.”

Massive shielding.
This is the game changer. The showstopper. The sea change. The paradigm shift.
The cosmic ray gorilla. Whatever you want to call it, it is the reality that most of what we are familiar with concerning human space flight is not going to work in deep space.
Massive Shielding=Nuclear Propulsion=Bombs
M=N=B
We have to transport nuclear materials to the Moon where we can light off a nuclear propulsion system. The Moon is where the ice-derived Water to fill up a Massive radiation shield is to be found.
Massive Shield=Water=Lunar Base
M=W=L
Sequentially: L=W=M=N=B
So, first and last, we need an HLV to get to this Lunar Base (where the Water for the shield is) and we need to safely transport Nuclear material there (and safely assemble and light off the Bombs to push the shield around).

Radiation shielding is the first determining factor in spaceship design and this largely determines the entire development of space travel.

I recently posted this on the only two other sites that will allow me to express my opinions;

I see the problem as one of self similarity; trying to go cheap being the downfall of all these schemes to work around human physiology.

When I first became interested in space travel several years ago I would comment on a couple blogs and find myself constantly arguing with private space proponents- and saying over and over again, “there is no cheap.” I was finally excommunicated from that bunch and banned from posting. They would start calling me an idiot and other insults and when I tried to return the favor the moderator would block my replies. The person who runs those two sites works for a firm promoting space tourism- go figure.

The problem is that while the aerospace industry made some money off the space program as an outgrowth of the military industrial complex, it soon became clear that spaceships are hard money- they have to work. The example of this is the outrage over the Apollo 1 fire and subsequent oversight of contractors- a practice which disappeared after Apollo and resulted in the Space Shuttle being such a poor design. A portion of the shuttle development money reportedly went under the table into the B-1 bomber program; how much we will never know. Swing wings are not easy to build which is why you do not see it anymore; cuts into profits.

The easy money of cold war toys has since defeated any move by industry to take up the cause of space exploration. No easy money in spaceships. People who want something for nothing rarely end up with anything worth anything. Trying to find cheap ways around furnishing explorers with the physcial conditions human beings evolved in is going to fail. On the other hand if we start with a baseline of one gravity and Earth level radiation we are bound to succeed.

The engineering solutions to this baseline requirement are as I have already detailed; a tether for gravity and a massive moonwater shield with bomb propulsion. That is EXACTLY how to do it and I do not see any one else offering anything else that will work- just waffling and spewing about R&D.
We have been doing R&D for over half a century. It is a reason to go that is supposedly lacking.

When that crater in Mexico was discovered in 1980 the cold war was reaching it’s crescendo and the massive extinction it caused was overshadowed by the threat of nuclear weapons. Impact defense is still the only path to all that DOD money for a Moon base.

http://www.sciencedaily.com/releases/2012/12/121231180632.htm

Excerpt: “Galactic cosmic radiation poses a significant threat to future astronauts,” said M. Kerry O’Banion, M.D., Ph.D., a professor in the University of Rochester Medical Center (URMC) Department of Neurobiology and Anatomy and the senior author of the study. “The possibility that radiation exposure in space may give rise to health problems such as cancer has long been recognized. However, this study shows for the first time that exposure to radiation levels equivalent to a mission to Mars could produce cognitive problems and speed up changes in the brain that are associated with Alzheimer’s disease.”

It appears when Eugene Parker wrote “Shielding Space Travelers” in 2006 he was right- and all the private space sycophants claiming radiation mitigation is trivial are wrong.

Only a massive water shield a minimum of 14 feet thick and massing 400 tons for a small capsule can shield human beings in deep space on long duration missions. And since a small capsule will not have sufficient space to keep a crew psychologically healthy on a multi-year journey it is likely such a shield will massive over a thousand tons.

This mass may seem to make Human Space Flight Beyond Earth and Lunar Orbit (HSF-BELO) impractical but in fact it is not an obstacle but an enabler. Nuclear Pulse Propulsion using bombs to push a spaceship to the outer solar sytem becomes more efficient the larger the ship and this amount of water is useful in a closed loop life support system.

Lighting off bombs in the Earth’s magnetosphere is not acceptable and this points to the Moon as the obvious place to launch nuclear missions and also to acquire the water for radiation shielding. The Space Launch System (SLS) is the human-rated Heavy Lift Vehicle (HLV) with a powerful escape system that can safely transport the required fissionables to the Moon.

2013 may be the year of the comet and the year of the spaceship if the two goals of protecting the planet from impacts and establishing off world colonies are finally recognized as vital to the survival of humankind.

http://news.yahoo.com/nowhere-japans-growing-plutonium-stockpile-064038796.html

A half century after being developed, nuclear pulse propulsion remains the only practical system of interplanetary travel. What is required to launch a bomb propelled mission to the outer solar system? Well, first you need.…..bombs.

There is no shortage of bomb material on planet Earth. The problem is lack of a vehicle that can get this material to the nearest place a nuclear mission can be launched; the Moon. For over a quarter of a century a launch vehicle capable of sending significant payloads (and people) to the Moon has been lacking. The Space Transportation System, aka the space shuttle, was a dead end as far as exploration due to the lack of funding for a Sidemount cargo version.

Now we wait on the SLS.

http://www.sciencedaily.com/releases/2012/12/121228100748.htm

Only this human rated Heavy Lift Vehicle (HLV) with a powerful escape tower will be suitable for transporting survivable packaged fissionables to the Moon. It is not only the fissionables that are required; hundreds of tons of water from lunar ice deposits are necessary to fill the radiation shield for any such Human Space Flight Beyond Earth Lunar Orbit (HSF-BELO).

Eventually lunar resources can be used to actually construct atomic spaceships and also the thorium reactors necessary to power colonies in the outer system. It is the establishment of a beam propulsion infrastructure that will finally open up the solar system to large scale development. This will require a massive infrastructure on the Moon. Such a base will serve as insurance against an extinction level event wiping out our species. As such it deserves a full measure of DOD funding. Like that trillion dollars that is going to be spent on the F-35 stealth fighter over the next half century.

Only monthly Heavy Lift Vehicle launches of payloads to the Moon can be considered as a beginning to a true space program- where Apollo left off. There is no cheap and there is no flexible path.

The Kline Directive: Theoretical-Empirical Relationship (Part 4)

Posted by Benjamin T. Solomon in business, cosmology, defense, economics, education, engineering, nuclear weapons, particle physics, philosophy, physics, policy, scientific freedom, spaceTagged , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , | 11 Comments on The Kline Directive: Theoretical-Empirical Relationship (Part 4)

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, Legal Standing, Safety Awareness, Economic Viability, Theoretical-Empirical Relationship, & Technological Feasibility.

In this post I have updated the Interstellar Challenge Matrix (ICM) to guide us through the issues so that we can arrive at interstellar travel sooner, rather than later:

Interstellar Challenge Matrix (Partial Matrix)

Propulsion Mechanism Relatively Safe? Theoretical-Empirical Relationship?
Conventional Fuel Rockets: Yes, but susceptible to human error. Known. Theoretical foundations are based on Engineering Feasible Theories, and have been evolving since Robert Goddard invented the first liquid-fueled rocket in 1926.
Antimatter Propulsion: No. Extensive gamma ray production (Carl Sagan). Issue is how does one protect the Earth? Capable of an End of Humanity (EOH) event. Dependent on Millennium Theories. John Eades states in no uncertain terms that antimatter is impossible to handle and create.
Atomic Bomb Pulse Detonation: No, because (Project Orion) one needs to be able to manage between 300,000 and 30,000,000 atomic bombs per trip. Known and based on Engineering Feasible Theories.
Time Travel: Do Not Know. Depends on how safely exotic matter can be contained. Dependent on a Millennium Theory. Exotic matter hypotheses are untested. No experimental evidence to show that Nature allows for a breakdown in causality.
String / Quantum Foam Based Propulsion: Do Not Know. Depends on how safely exotic matter can be contained. Dependent on a Millennium Theory. String theories have not been experimentally verified. Exotic matter hypotheses are untested. Existence of Quantum Foam now suspect (Robert Nemiroff).
Small Black Hole Propulsion: No. Capable of an End Of Humanity (EOH) event Don’t know if small black holes really do exist in Nature. Their theoretical basis should be considered a Millennium Theory.

It is quite obvious that the major impediments to interstellar travel are the Millennium Theories. Let us review. Richard Feynman (Nobel Prize 1965) & Sheldon Lee Glashow (Nobel Prize 1979) have criticized string theory for not providing novel experimental predictions at accessible energy scales, but other theoretical physicists (Stephen Hawking, Edward Witten, Juan Maldacena and Leonard Susskind) believe that string theory is a step towards the correct fundamental description of nature. The Wikipedia article String Theory gives a good overview, and notes other critics and criticisms of string theories. In What is String Theory? Alberto Güijosa explains why string theories have come to dominate theoretical physics. It is about forces, and especially about unifying gravity with the other three forces.

Note, strings expand when their energy increases but the experimental evidence aka Lorentz-Fitzgerald transformations tell us that everything contracts with velocity i.e. as energy is increased.

In my opinion, the heady rush to a theory of everything is misguided, because there is at least one question that physics has not answered that is more fundamental than strings and particles. What is probability and how is it implemented in Nature?

Probabilities are more fundamental than particles as particles exhibit non-linear spatial probabilistic behavior. So how can one build a theory of everything on a complex structure (particles), if it cannot explain something substantially more fundamental (probabilities) than this complex structure? The logic defies me.

We can ask more fundamental questions. Is this probability really a Gaussian function? Experimental data suggests otherwise, a Var-Gamma distribution. Why is the force experienced by an electron moving in a magnetic field, orthogonal to both the electron velocity and the magnetic field? Contemporary electromagnetism just says it is vector cross product, i.e. it is just that way. The cross product is a variation of saying it has to be a Left Hand Rule or a Right Hand Rule. But why?

Is mass really the source of a gravitational field? Could it not be due to quark interaction? Can we device experiments that can distinguish between the two? Why do photons exhibit both wave and particle behavior? What is momentum, and why is it conserved? Why is mass and energy equivalent?

Can theoretical physicists construct theories without using the laws of conservation of mass-energy and momentum? That would be a real test for a theory of everything!

In my research into gravity modification I found that the massless formula for gravitational acceleration, g=τc2, works for gravity, electromagnetism and mechanical forces. Yes, a unification of gravity and electromagnetism. And this formula has been tested and verified with experimental data. Further that a force field is a Non Inertia (Ni) field, and is present where ever there is a spatial gradient in time dilations or velocities. This is very different from the Standard Model which requires that forces are transmitted by the exchange of virtual particles.

So if there is an alternative model that has united gravity and electromagnetism, what does that say for both string theories and the Standard Model? I raise these questions because they are opportunities to kick start research in a different direction. I answered two of these questions in my book. In the spirit of the Kline Directive can we use these questions to explore what others have not, to seek what others will not, to change what others dare not?

That is why I’m confident that we will have real working gravity modification technologies by 2020.

In concluding this section we need to figure out funding rules to ensure that Engineering Feasible and 100-Year Theories get first priority. That is the only way we are going to be able to refocus our physics community to achieve interstellar travel sooner rather than later.

The Kline Directive: Economic Viability

Posted by Benjamin T.

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 Economic Viability. I have proposed the Interstellar Challenge Matrix (ICM) to guide us through the issues so that we can arrive at interstellar travel sooner, rather than later. Let us review the costs estimates of the various star drives just to reach the velocity of 0.1c, as detailed in previous blog posts:

Interstellar Challenge Matrix (Partial Matrix)

Propulsion Mechanism Legal? Costs Estimates
Conventional Fuel Rockets: Yes Greater than US$1.19E+14
Antimatter Propulsion: Do Not Know. Between US$1.25E+20 and US$6.25E+21
Atomic Bomb Pulse Detonation: Illegal. This technology was illegal as of 1963 per Partial Test Ban Treaty Between $2.6E12 and $25.6E12 . These are Project Orion original costs converted back to 2012 dollar. Requires anywhere between 300,000 and 30,000,000 bombs!!
Time Travel: Do Not Know. Requires Exotic Matter, therefore greater than antimatter propulsion costs of US$1.25E+20
Quantum Foam Based Propulsion: Do Not Know. Requires Exotic Matter, therefore greater than antimatter propulsion costs of US$1.25E+20
Small Black Hole Propulsion: Most Probably Illegal in the Future Using CERN to estimate. At least US$9E+9 per annual budget. CERN was founded 58 years ago in 1954. Therefore a guestimate of the total expenditure required to reach its current technological standing is US$1.4E11.

Note Atomic Bomb numbers were updated on 10/18/2012 after Robert Steinhaus commented that costs estimates “are excessively high and unrealistic”. I researched the topic and found Project Orion details the costs, of $2.6E12 to $25.6E12, which are worse than my estimates.

These costs are humongous. The Everly Brothers said it the best.

Let’s step back and ask ourselves the question, is this the tool kit we have to achieve interstellar travel? Are we serious? Is this why DARPA — the organization that funds many strange projects — said it will take more than a 100 years? Are we not interested in doing something sooner? What happened to the spirit of the Kline Directive?

From a space exploration perspective economic viability is a strange criterion. It is not physics, neither is it engineering, and until recently, the space exploration community has been government funded to the point where realistic cost accountability is nonexistent.

Don’t get me wrong. This is not about agreeing to a payment scheme and providing the services as contracted. Government contractors have learned to do that very well. It is about standing on your own two feet, on a purely technology driven commercial basis. This is not an accounting problem, and accountants and CFOs cannot solve this. They would have no idea where to start. This is a physics and engineering problem that shows up as an economic viability problem that only physicists and engineers can solve.

The physics, materials, technology and manufacturing capability has evolved so much that companies like Planetary Resources, SpaceX, Orbital Sciences Corp, Virgin Galactic, and the Ad Astra Rocket Company are changing this economic viability equation. This is the spirit of the Kline Directive, to seek out what others would not.

So I ask the question, whom among you physicist and engineers would like to be engaged is this type of endeavor?

But first, let us learn a lesson from history to figure out what it takes. Take for example DARPA funding of the Gallium Arsenide. “One of DARPA’s lesser known accomplishments, semiconductor gallium arsenide received a push from a $600-million computer research program in the mid-1980s. Although more costly than silicon, the material has become central to wireless communications chips in everything from cellphones to satellites, thanks to its high electron mobility, which lets it work at higher frequencies.”

In the 1990s Gallium Arsenide semiconductors were so expensive that “silicon wafers could be considered free”. But before you jump in and say that is where current interstellar propulsion theories are, you need to note one more important factor.

The Gallium Arsenide technology had a parallel commercially proven technology in place, the silicon semiconductor technology. None of our interstellar propulsion technology ideas have anything comparable to a commercially successful parallel technology. (I forgot conventional rockets. Really?) A guesstimate, in today’s dollars, of what it would cost to develop interstellar travel propulsion given that we already had a parallel commercially proven technology, would be $1 billion, and DARPA would be the first in line to attempt this.

Given our theoretical physics and our current technological feasibility, this cost analysis would suggest that we require about 10 major technological innovations, each building on the other, before interstellar travel becomes feasible.

That is a very big step. Almost like reaching out to eternity. No wonder Prof Adam Franks in his July 24, 2012 New York Times Op-Ed, Alone in the Void, wrote “Short of a scientific miracle of the kind that has never occurred, our future history for millenniums will be played out on Earth”.

Therefore, we need to communicate to the theoretical physics community that they need get off the Theory of Everything locomotive and refocus on propulsion physics. In a later blog posting I will complete the Interstellar Challenge Matrix (ICM). Please use it to converse with your physicist colleagues and friends about the need to focus on propulsion physics.

In the spirit of the Kline Directive — bold, explore, seek & change — can we identify the 10 major technological innovations? Wouldn’t that keep you awake at night at the possibility of new unthinkable inventions that will take man where no man has gone before?

PS. I was going to name the Interstellar Challenge Matrix (ICM), the Feasibility Matrix for Interstellar Travel (FMIT), then I realized that it would not catch on at MIT, and decided to stay with ICM.

Previous posting in this Debunking Series.

In this post we will look at the last three types of engines. Can these engine technologies be debunked?

Start with the boring stuff. Nuclear/plasma engines. For more information look up Franklin Chang-Diaz’s Variable Specific Impulse Magnetoplasma Rocket (VASIMR). Real. Cannot be debunked.

Now for the more interesting stuff. The second is Pulse Detonation Engines (PDE). This type of engine uses detonation waves to combust fuel and oxidizer mixture. “The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave initiated by an ignition source.” Theoretically this type of engine is capable of speeds from subsonic to Mach 5.

Here is an UT Arlington Feb 2008 YouTube video that shows how elegantly simple, a workable engineering concept is. According to the posting this engine was built and tested in 2005.

Here is a link to Mojave Skies blog posting which shows photographs of an Air Force Research Laboratory (AFRL) subsonic pulsed detonation engine trials (about May 2008), made from off-the-shelf automotive parts. Impressive!

Some history regarding the Mojave Skies blog posting. Scaled Composites is led by Burt Rutan, whose team won the Ansari X-Prize in 2004. Scaled Composites is now owned by Northrup Grumman a defense contractor. What a small world. Everyone is interconnected to everyone else.

What about supersonic trials?

Here is a link to Military, Aviation & Space forum where the jet plumes appeared to be pulsed. The date of this posting is Feb 2008, while the AFRL’s press release is dated May 2008. Here is the AboveTopSecret’s link to a Jun 2008 discussion about what appears to be PDE aircrafts in action. The writers appear to be experienced and leaning toward the PDE aircrafts in the video being real.

My guess is that conventional fuel pulse detonation engines are a reality in experimental supersonic aircrafts, and that the May 2008 AFRL’s press release is about making PDEs cheaper. These engines are real and cannot be debunked.

Now for the third type of engine technology, atomic bomb or nuclear pulse engines. It is quite obvious from the Medusa design that the nuclear energy released by such a device that is used to propel this starship is only 1/6th of the useful energy. Note, useful energy is less than total energy released. Therefore this is an inefficient design.

Further, as the Wikipedia article on nuclear pulse engines points out, there is the Partial Test Ban Treaty that makes such engines illegal. Debunked.

Therefore, nuclear or atomic bomb pulsed engines are debunked, and people who support such ideas are out of touch with reality. Let me quote Billy Currington “God is great, beer is good, people are crazy”.

I do not regret voting for this President and I would and will do it again. However.……I am not happy about our space program. Not at all. One would think there would be more resistance concerning the privatization of space and the inferior launch vehicles being tested or proposed. Indeed there would be objections except for a great deception being perpetrated on a nation ignorant of the basic facts about space flight. The private space gang has dominated public discourse with very little answering criticism of their promises and plans.
This writer is very critical of the flexible path.

It is a path to nowhere.

Compared to the accomplishments of NASA’s glory days, there is little to recommend the players in the commercial crew game. The most fabulous is Space X, fielding a cheap rocket promising cheap lift. There is so little transparency concerning the true cost of their launches that one space-faring nation has called the bluff and stated SpaceX launch prices are impossible. The Falcon 9, contrary to stellar advertising, is a poor design in so many ways it is difficult to know where to begin the list. The engines are too small and too many, the kerosene propellant is inferior to hydrogen in the upper stage, and promising to reuse spent hardware verges on the ridiculous. Whenever the truth about the flexible path is revealed, the sycophants begin to wail and gnash their teeth.

The latest craze is the Falcon “heavy.” The space shuttle hardware lifted far more, though most of the lift was wasted on the orbiter. With 27 engines the faux heavy is a throwback to half a century ago when clusters of small engines were required due to nothing larger being available. The true heavy rocket of the last century had five engines and the number of Falcon engines it would take to match the Saturn V proves just how far the mighty have fallen.

Long, long posts, doubling as SpaceX advertisements, swamp any forum where the deception is exposed. The most popular and endlessly repeated dogma concerns fuel depots. Refueling in space is hyped as the answer to all problems. Unfortunately the chances of making it work with the selected propellant- liquid hydrogen- are not good. This kind of blasphemy is sure to bring howls of protest on any forum where it appears. The sad truth is the American people are being conned into throwing away the Heavy Lift Infrastructure that is the only path to Beyond Earth Orbit Human Space Flight. SpaceX is more of an exploitation company to charge the taxpayer twice than aerospace company. Everything they are pushing- from the engine design to friction stir welded stages, to the heat shield on the capsule has all been developed by NASA on the taxpayers dime. They use NASA labs and engineers for token payment and then advertise low prices. It is a scam. Worse than a scam, it is a distraction from and drain on funds from the only real possibility for space travel on the horizon; the Space Launch System (SLS).

LEO is not space exploration. It is not space travel. It may have qualified as space flight at one time but not anymore. It is endless circles at very high altitude. If any achievement deserves the “been there” scoff it is Low Earth Orbit.

Human beings left Earth at 24,200 mph (38,938 km/hr) in December of 1968. In December of 1972 we returned and have not gone back. We did continue Heavy Lift launches after Apollo with the Space Shuttle- but the STS did not launch humans beyond earth orbit. Due to lack of funding the Shuttle regrettably launched a hundred tons of wings, landing gear, and never full cargo bay over one hundred times so they could come right back. What little stayed up there at very high altitude going in circles is that higher price tag people cry about.

To expand the human race into the solar system requires nuclear energy. We will not be assembling, testing, and lighting off any nuclear systems in LEO. We do however have a human rated capsule with a powerful escape system almost ready that is suitable for transporting fissionables directly to the Moon- where we can assemble, test, and light off nukes. To send that capsule directly to the moon, and the human beings to construct a base that can support a nuclear mission, we need an HLV with hydrogen upper stages. The hydrogen upper stages are what made Apollo successful by making a heavy payload go fast. That vehicle is a few years away and sooner with more money. The DOD has vast resources it expends on weapons that do not protect us from two clear and present dangers; impacts and plagues. I often give examples on this site of “cold war toys” that are “hideously expensive” and do not seem to work right or do anything magical. That big rocket is the magic that will open the solar system to human colonization. Private space efforts are not capable of making any of it happen. This is why I consider the whole “new space” movement as being essentially rich hobbyists selling tourist trips. My thoughts on this “narrow and inflexible path” are based largely on the work of Freeman Dyson and Eugene Parker- and the discovery of millions of tons of water on the Moon.

Despite having “been there,” the Moon is the next step in opening up the solar system to human exploration and colonization. Low Earth Orbit is being sold as space travel even though to travel, you have to go somewhere. The battle cry of “cheap lift” is promoting the equivalent of the “liar loans” that wrecked the housing market. Falling for this something for nothing too good to be true rip-off will leave the U.S. trapped. Decades more of nothing but more endless circles at very high altitude. Mars is used as a marketing gimmick but is really just a rock with a deep gravity well. Everyone seems to think it is “just close enough” for chemical propulsion. It is not. If you are going to build the necessary Atomic Spaceship (and we would have to have a moonbase to launch a nuclear mission) you might as well go someplace really interesting.

All those places are in the outer solar system.

To establish a moonbase requires the Space Launch System to be put into service. There is no substitute for a Heavy Lift Vehicle with hydrogen upper stages.

The 130 ton lift of the proposed SLS is also at this time slated to be used as a crew vehicle. This was one of the worst mistakes of the shuttle program. The crew capsules being tested and built by SpaceX and Boeing pack seven astronauts into a vehicle without a proper escape system and, in the case of SpaceX, doubling as a cargo vehicle. Both of these vehicles have an escape-system-that-is-not-an-escape-system. These underpowered hypergolic systems are not very good at saving a crew but will work great raising the orbit of tourist space stations. This is another one of those worst mistakes being repeated.

Infomercial hype aside, the falcon “heavy” and Delta IV are not HLV’s. This misinformation deceives the public and makes the average citizen think the SpaceX hobby rocket is a Saturn V. At a thrust of around 100,000 pounds each it would take 72 merlins to equal the thrust of the SRB’s on SLS, not counting what the 4 liquid hydrogen engines also produce- with much greater efficiency than Kerosene.

The real problem with the U.S. space program is obvious to anyone looking at how much money is spent by the DOD. It is always interesting to hear sermons about how critical surveillance satellites are to fighting illiterate mountain tribesman. Any DOD contractor hearing complaints about NASA wasting money breaks down in maniacal laughter. One of my favorite talking points is that we can train our young people to clear buildings with automatic weapons or we can train them to build spaceships; either way the money will get spent.

Take a look at military spending increases and it is obvious funding for spaceflight can go up. And there IS a valid DOD mission BEO and BELO (Beyond Earth and Lunar Orbit). The valid military mission is impact defense and establishing outposts in the outer system- but this is hard money the aerospace industry wants nothing to do with. Unlike so many easy money weapon systems, spaceships have to actually work.
