Explaining 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.

Cosmic Ray Gorilla

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.

13: The Year of The Comet

Posted by in categories: asteroid/comet impacts, counterterrorism, defense, economics, ethics, events, existential risks, futurism, geopolitics, habitats, human trajectories, lifeboat, military, philosophy, policy, space, sustainability, transparency

A happy new year to the human race from it’s most important member; me. Since self-worship seems to be the theme of the new American ideal I had better get right with me.

With my government going over the fiscal cliff it would appear that the damned soul of Ayn Rand is exerting demonic influence on the political system through worship of the individual. The tea party has the Republicans terrified of losing their jobs. Being just like me, those individuals consider themselves the most important person on the planet- so I cannot fault them.

As Ayn Rand believed, “I will not die, it’s the world that will end”, so who cares about the collective future of the human race? Towards the end of 2013 the heavens may remind us the universe does not really care about creatures who believe themselves all important. The choice may soon be seen clearly in the light of the comet’s tail; the glorification of the individual and the certain extinction of our race, or the acceptance of a collective goal and our continued existence.

Ayn Rand made her choice but most of us have time to choose more wisely. I pray for billions, tens and hundreds of billions of dollars- for a Moonbase.

Forty Tons of Plutonium for Bomb Propulsion?

Posted by in categories: defense, engineering, existential risks, military, nuclear energy, nuclear weapons, space

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.

Smithsonian National Air and Space Museum: No Lifeboats Please

Posted by in categories: defense, education, engineering, existential risks, finance, military, space

It was on a long-haul flight many months ago that I recalled a visit to the National Air and Space Museum [1] to a fellow passenger whom I struck up conversation with. Asking if I could recommend somewhere to visit in Washington DC, I recounted how I had spent an entire day amazing at the collection of historic aircraft and spacecraft on my only visit to that city fifteen years or so previous as a young adult — and as always a kid at heart.

Seeing the sheer scale of the F-1 engine for the Saturn 5 rocket first hand, stepping inside an Apollo command module identical to those used during the Apollo program, not to mention seeing full life-size replicas of the Lunar Roving Vehicle, an Apollo Lunar Module and for some reason what seemed most surreal to me… the Viking 1 Lander. This was enchantment.

However, for all the amazement that such a museum can provide, it is also a saddening reminder that what once was the forefront of human ambition and endeavor has now been largely resigned to history. NASA budgets are cut annually [2] whilst military expenditure takes ever more precedence. A planned six percent budget decrease in 2013 is the equivalent savings to three hours of the Iraq and Afghanistan Wars. Instead of reaching to explore outer-space we are encouraged to get excited about the equivalent billions [3] invested on science exploring the subatomic inner-space world. Meanwhile, we tend to forget that the ambitions of space exploration are not just to satisfy some wide-eyed childhood yearning to explore, but the serious and sobering prospect of needing to ensure that we as a species can eventually colonize to other worlds and ensure we are not counting down the days to our extinction on an ever-more-precarious planetary solitude.

In the face of such indifference, such concepts of lifeboats have become marginalized to what is perceived to be a realm solely for loons and dreamers, or ‘space cadets’ as we used to call them back in the days of school. The trillion dollar question really is what it takes to redirect all that military investment into science & exploration instead. It is down to credibility. Governments shy away from investing public funds when there is a lack of credibility.

Our Youth, Thinking Outside the Box

Posted by in categories: business, defense, economics, education, engineering, human trajectories, military, philosophy, space, sustainability

Recently I attended the AIAA Rocky Mountain Region’s First Annual Technical Symposium, October 26, 2012. Link to Symposium Photos, here. Link to Symposium Presentations, here.

I must congratulate many of the presenters, our youth, our next generation leaders, for thinking outside the box. And I congratulate their supervisors, advisors and team members for facilitating a supportive environment that nurtures outside the box thinking.

Here is why. Several remarkable papers were presented. For example, Tom Joslyn (Lt. Col, PhD) presented “Use of Liquid Droplet Stream Momentum Transfer for Lunar and Interplanetary Missions”. By using liquid droplets to conserve and transfer momentum between the momentum storage spacecraft and the lunar landing spacecraft, one could reduce the LEO mass from 200,000 kg to 24,500 kg. The presentation wasn’t about theory. It was about the how such a concept would be Engineering Feasible. The type of liquids required, and the ejection and capture systems required. That is impressive.

Second, “Cockpit of the Future” by the Capstone Team. They presented many new concepts like Palm Piloteer, haptic feedback suits, wrap around displays and seat designs.

The Kline Directive: Technological Feasibility (2b)

Posted by in categories: business, defense, education, engineering, military, particle physics, philosophy, physics, scientific freedom, space, transparency

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 Relationships, and Technological Feasibility.

In this post I discuss three concepts, that if implemented should speed up the rate of innovation and discovery so that we can achieve interstellar travel within a time frame of decades, not centuries.

Okay, what I’m going to say will upset some physicists, but I need to say it because we need to resolve some issues in physics to distinguish between mathematical construction and conjecture. Once we are on the road to mathematical construction, there is hope that this will eventually lead to technological feasibility. This post is taken from my published paper “Gravitational Acceleration Without Mass And Noninertia Fields” in the peer reviewed AIP journal, Physics Essays, and from my book An Introduction to Gravity Modification.

The Universe is much more consistent than most of us (even physicists) suspect. Therefore, we can use this consistency to weed out mathematical conjecture from our collection of physical hypotheses. There are two set of transformations that are observable. The first, in a gravitational field at a point where acceleration is a compared to a location at 0 an infinite distance from the gravitational source, there exists Non-Linear transformations Γ(a) which states that time dilation ta/t0, length contraction x0/xa, and mass increase ma/m0, behave in a consistent manner such that:

The Kline Directive: Technological Feasibility (2a)

Posted by in categories: defense, education, engineering, ethics, military, open source, philosophy, physics, policy, scientific freedom, space, transparency

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 Relationships, and Technological Feasibility.

In this set of posts I discuss three concepts. If implemented these concepts have the potential to bring about major changes in our understanding of the physical Universe. But first a detour.

In my earlier post I had suggested that both John Archibald Wheeler and Richard Feynman, giants of the physics community, could have asked different questions (what could we do differently?) regarding certain solutions to Maxwell’s equations, instead of asking if retrocausality could be a solution.

I worked 10 years for Texas Instruments in the 1980s & 1990s. Corporate in Dallas, had given us the daunting task of raising our Assembly/Test yields from 83% to 95%, within 3 years, across 6,000 SKUs (products), with only about 20+ (maybe less) engineers, and no assistance from Dallas. Assembly/Test skills had moved offshore, therefore, Dallas was not in a position to provide advice. I look back now and wonder how Dallas came up with the 95% number.

The Kline Directive: Technological Feasibility (1)

Posted by in categories: business, defense, engineering, military, philosophy, physics, policy, scientific freedom, space

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 Relationships, and Technological Feasibility.

In this post I will explore Technological Feasibility. At the end of the day that is the only thing that matters. If a hypothesis is not able to vindicate itself with empirical evidence it will not become technologically feasible. If it is not technologically feasible then it stands no chance of becoming commercially viable.

If we examine historical land, air and space speed records, we can construct and estimate of velocities that future technologies can achieve, aka technology forecasting. See table below for some of the speed records.

Year Fastest Velocity Craft Velocity (km/h) Velocity (m/s)
2006 Escape Earth New Horizons 57,600 16,000
1976 Capt. Eldon W. Joersz and Maj. George T. Morgan Lockheed SR-71 Blackbird 3,530 980
1927 Car land speed record (not jet engine) Mystry 328 91
1920 Joseph Sadi-Lecointe Nieuport-Delage NiD 29 275 76
1913 Maurice Prévost Deperdussin Monocoque 180 50
1903 Wilbur Wright at Kitty Hawk Wright Aircraft 11 3

A quick and dirty model derived from the data shows that we could achieve velocity of light c by 2151 or the late 2150s. See table below.

The Kline Directive: Economic Viability

Posted by in categories: business, complex systems, defense, economics, education, engineering, finance, military, nuclear weapons, philosophy, physics, policy, scientific freedom, space, sustainability

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.
