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.”

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.

I’d like to announce the start of the Indiegogo.com campaign for Software Wars, the movie. It is called Software Wars, but it also talks about biotechnology, the space elevator and other futuristic topics. This movie takes many of the ideas I’ve posted here and puts them into video form. It will be understandable to normal people but interesting to people like us. I would appreciate the support of Lifeboat for this project.

Using an innocuous bacterial virus, bioengineers have created a biological mechanism to send genetic messages from cell to cell. The system greatly increases the complexity and amount of data that can be communicated between cells and could lead to greater control of biological functions within cell communities…

In harnessing DNA for cell-cell messaging the researchers have also greatly increased the amount of data they can transmit at any one time. In digital terms, they have increased the bit rate of their system. The largest DNA strand M13 is known to have packaged includes more than 40,000 base pairs. Base pairs, like 1s and 0s in digital encoding, are the basic building blocks of genetic data. Most genetic messages of interest in bioengineering range from several hundred to many thousand base pairs.

Ortiz was even able to broadcast her genetic messages between cells separated by a gelatinous medium at a distance of greater than 7 centimeters.

“That’s very long-range communication, cellularly speaking,” she said.

Down the road, the biological Internet could lead to biosynthetic factories in which huge masses of microbes collaborate to make more complicated fuels, pharmaceuticals and other useful chemicals. With improvements, the engineers say, their cell-cell communication platform might someday allow more complex three-dimensional programming of cellular systems, including the regeneration of tissue or organs.

I have been meaning to read a book coming out soon called Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves. It’s written by Harvard biologist George Church and science writer Ed Regis. Church is doing stunning work on a number of fronts, from creating synthetic microbes to sequencing human genomes, so I definitely am interested in what he has to say. I don’t know how many other people will be, so I have no idea how well the book will do. But in a tour de force of biochemical publishing, he has created 70 billion copies. Instead of paper and ink, or pdf’s and pixels, he’s used DNA.

Much as pdf’s are built on a digital system of 1s and 0s, DNA is a string of nucleotides, which can be one of four different types. Church and his colleagues turned his whole book–including illustrations–into a 5.27 MB file–which they then translated into a sequence of DNA. They stored the DNA on a chip and then sequenced it to read the text. The book is broken up into little chunks of DNA, each of which has a portion of the book itself as well as an address to indicate where it should go. They recovered the book with only 10 wrong bits out of 5.27 million. Using standard DNA-copying methods, they duplicated the DNA into 70 billion copies.

Scientists have stored little pieces of information in DNA before, but Church’s book is about 1,000 times bigger. I doubt anyone would buy a DNA edition of Regenesis on Amazon, since they’d need some expensive equipment and a lot of time to translate it into a format our brains can comprehend. But the costs are crashing, and DNA is a far more stable medium than that hard drive on your desk that you’re waiting to die. In fact, Regenesis could endure for centuries in its genetic form. Perhaps librarians of the future will need to get a degree in biology…

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.

It is a race against time- will this knowledge save us or destroy us? Genetic modification may eventually reverse aging and bring about a new age but it is more likely the end of the world is coming.

The Fermi Paradox informs us that intelligent life may not be intelligent enough to keep from destroying itself. Nothing will destroy us faster or more certainly than an engineered pathogen (except possibly an asteroid or comet impact). The only answer to this threat is an off world survival colony. Ceres would be perfect.

A secret agent travels to a secret underground desert base being used to develop space weapons to investigate a series of mysterious murders. The agent finds a secret transmitter was built into a supercomputer that controls the base and a stealth plane flying overhead is controlling the computer and causing the deaths. The agent does battle with two powerful robots in the climax of the story.

Gog is a great story worthy of a sci fi action epic today- and was originally made in 1954. Why can’t they just remake these movies word for word and scene for scene with as few changes as possible? The terrible job done on so many remade sci fi classics is really a mystery. How can such great special effects and actors be used to murder a perfect story that had already been told well once? Amazing.

In contrast to Gog we have the fairly recent movie Stealth released in 2005 that has talent, special effects, and probably the worst story ever conceived. An artificially intelligent fighter plane going off the reservation? The rip-off of HAL from 2001 is so ridiculous.

Fantastic Voyage (1966) was a not so good story that succeeded in spite of stretching suspension of disbelief beyond the limit. It was a great movie and might succeed today if instead of miniaturized and injected into a human body it was instead a submarine exploring a giant organism under the ice of a moon in the outer solar system. Just an idea.

The glacial pace of NASA’s human spaceflight program –even with the glaciers melting- may possibly see human beings leave Earth’s gravitational field in 2025. Possibly.

The missing piece of the puzzle is a radiation sanctuary massive enough to protect a crew from a major solar event on such a journey.
