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.

Gravity Modification – What Went Wrong?

Posted by in categories: business, chemistry, defense, education, engineering, physics, policy, scientific freedom, space, transparency

Recently, I met Josh Hopkins of Lockheed’s Advanced Programs, AIAA Rocky Mountain Region’s First Annual Technical Symposium (RMATS), October 26, 2012. Josh was the keynote speaker at this RMATS. Here is his presentation. After his presentation we talked outside the conference hall. I told him about my book, and was surprised when he said that two groups had failed to reproduce Podkletnov’s work. I knew one group had but a second? As we parted we said we’d keep in touch. But you know how life is, it has the habit of getting in the way of exciting research, and we lost touch.

About two weeks ago, I remembered, that Josh had said that he would provide some information on the second group that had failed to reproduce Podkletnov’s work. I sent him an email, and was very pleased to hear back from him and that the group’s finding had been published under the title “Gravity Modification by High-Temperature Semiconductors”. The authors were C. Woods, S. Cooke, J. Helme & C. Caldwell. Their paper was published in the 37th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 8–11 July 2001, Salt Lake City, Utah. I bought a copy for the AIAA archives, and read it, reread it, and reread it.

Then I found a third team they published their lack of findings “Gravity Modification Experiments Using a Rotating Superconducting Disk and Radio Frequency Fields”. The authors were G. Hathaway, B. Cleveland and Y. Bao. Published in Physica C, 2003.

Both papers focused on attempting to build a correct superconducting disc. At least Wood et al said “the tests have not fulfilled the specified conditions for a gravity effect”. The single most difficult thing to do was to build a bilayered superconducting disc. Woods et al tried very hard to do so. Reading through Hathaway et all paper suggest that they too had similar difficulties. Photo shows a sample disc from Woods’ team. Observe the crack in the middle.

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.

2012 was Great and may 2013 be Extraordinary

Posted by in categories: business, education, engineering, ethics, fun, human trajectories, lifeboat, media & arts, open access, open source, policy, scientific freedom, space, transparency

May peace break into your home and may thieves come to steal your debts.
May the pockets of your jeans become a magnet for $100 bills.
May love stick to your face like Vaseline and may laughter assault your lips!
May happiness slap you across the face and may your tears be that of joy
May the problems you had, forget your home address!

In simple words .….….……May 2013 be EXTRAORDINARY … the best year of your life!!! Simply the best New Year greeting anyone has sent to me. This was from Robert White of Extraordinary People.

This morning I checked the Lifeboat stats for 2012. When I started blogging for Lifeboat at the end of July, we ended July 2012 with 42,771 unique visitors. We closed 2012 with 90,920 unique visitors for the month December. Wow! Our blogging has become more relevant, and more thought provoking. As a community of bloggers (with the exception of one) we have moved away from the 3 Cs of pseudoscience. Clouding the field. Confusing the public’s perception. Chasing away talent.

How did we do this? By backing up our discussions with hard facts, robust debate and real numbers. From years if not decades of investigation in our field of research. By speaking from our own unique experience. By sharing that unique experience with our readers.

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.

Gravity Modification – New Tools

Posted by in categories: business, cosmology, defense, education, engineering, general relativity, particle physics, philosophy, physics, policy, space

To understand why gravity modification is not yet a reality, let’s analyze other fundamental discoveries/inventions that changed our civilization or at least the substantially changed the process of discovery. There are several that come to mind, the atomic bomb, heavier than air manned flight, the light bulb, personal computers, and protein folding. There are many other examples but these are sufficient to illustrate what it takes. Before we start, we have to understand four important and related concepts.

(1) Clusters or business clusters, first proposed by Harvard prof. Michael Porter, “a business cluster is a geographic concentration of interconnected businesses, suppliers, and associated institutions in a particular field. Clusters are considered to increase the productivity with which companies can compete, nationally and globally”. Toyota City which predates Porter’s proposal, comes to mind. China’s 12 new cities come to mind, and yes there are pro and cons.

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.

Gravity Modification – What is it?

Posted by in categories: cosmology, defense, economics, engineering, general relativity, particle physics, physics, policy, space

OK, why do we need a different technology to achieve commercial viability (as in mass space tourism) for either interplanetary or interstellar travel?

In many of my previous posts I had shown that all the currently proposed technologies or technologies to be, are either phenomenally expensive (on the order of several multiples of World GDP), bordering on the impossible or just plain conjecture. This is very unfortunate, as I was hoping that some of the proposals would at least appear realistic, but no joy. I feel very sorry for those who are funding these projects. For a refresher I have posted an updated version of the Interstellar Challenge Matrix (ICM) here which documents 5 of the 11 inconsistencies in modern physics. I give permission to my readers to use this material for non-commercial or academic uses.

I recently completed the 12-year study into the theoretical & technological feasibility of gravity modification published under the title An Introduction to Gravity Modification, 2nd Edition. For the very first time we now have a scientific definition for gravity modification:

Gravity modification is defined as the modification of the strength and/or direction of the gravitational acceleration without the use of mass as the primary source of this modification, in local space time. It consists of field modulation and field vectoring. Field modulation is the ability to attenuate or amplify a force field. Field vectoring is the ability to change the direction of this force field.

The Overview Effect and the Psychology of Cosmic Awe

Posted by in categories: cosmology, philosophy, space

The spirituality of space exploration as self-exploration.

Since the dawn of recorded history, humanity has been mesmerized by Earth’s place in the cosmos. Overview is a fascinating short film by Planetary Collective, written by Frank White, exploring the “overview effect” — the profound, shocking feeling that grips astronauts as they see our planet hang in space and the strange new self-awareness it precipitates. The film is based on Frank White’s 1987 book The Overview Effect: Space Exploration and Human Evolution and celebrates the 40th anniversary of NASA’s iconic Blue Marble photograph
