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.

!! JUST TWO WEEKS !!

Posted by in categories: existential risks, particle physics

Please, Dear CERN:

Stop for just two weeks ahead of schedule and the whole planet will applaud.

Everyone is vaguely aware that there exists a 4 years old new result that totally upsets the properties of black holes – the little monsters that CERN is attempting to produce every day.

CERN’s sensors cannot detect them by design, but the first slow enough specimen to stay inside earth will shrink the latter to 2 cm in a few years’ time. No specialist on the planet contradicts my Telemach theorem, published in the African Journal of Mathematics.

Visualizing the World and its Dangers

Posted by in categories: existential risks, lifeboat, particle physics, rants

I want to start a project of better visualization of the problems we face. We ask children to visualize in school but we all could use it. In the common economic discussions trillion dollar budgets and a million dollars are discussed interchangeability shows lack of visualization. The West is heading for currency collapse but austerity measures in Greece just add to unemployment not debt reduction, why is this so hard to visualize?

One clear way to shore up the US economy is to end foreign bases and end the embargo of Cuba. Boycotts hurt both sides, the Cuban economy is smaller so it hurts them more. The US economy is shaky so at some point embargo’s may be the straw that makes us fall apart.

Is Failure to Prepare Our Silent Existential Event?

Posted by in categories: education, existential risks, lifeboat, sustainability

Note: The below is exclusively about the United States of America, yet the theme is international.

Each time an extreme weather event takes place humanity is reminded again that basic preparation for an off-grid experience did not take place across large swaths of an affected population. Ironically, it does not begin to take place, publicly and en masse, after the event.

Saving humanity will have a lot to do with teaching a kid to build a fire, in the near term. More esoteric “preservers” and “shields” have their place, but “Scout” knowledge can produce immediate quantitative and qualitative improvements in humanity’s survival capabilities, fast.

After weather-induced disasters, our tendency is toward construction of physical things – better towers, more resilient dams, improved architecture. Seldom do we do anything to improve ourselves. Thousands remain helpless and dependent in the face of the Hurricane “Sandy” aftermath.

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.
