Lifeboat Foundation Interview on Betterhumans

Posted by in category: lifeboat

Recently, our international spokesperson, Philippe Van Nedervelde, spoke to the deputy editor of Betterhumans, Parish Mozdzierz, on the Lifeboat Foundation, its goals and activities. Here is the first question:

Betterhumans: How did the formation of the Lifeboat Foundation come about?

Philippe Van Nedervelde: Lifeboat Foundation’s founder, Eric Klien, was shaken wide awake by 9/11. The new reality of what we call (exponentially accelerating) “Asymmetric Destructive Capability” (ADC) fully hit him: ever smaller groups of people can create ever more enormous amounts of damage. And all of this thanks to advances in technology. As a bracelet-wearing cryonicist, he knew of the potentials of nanotechnology (having attended MIT Nanotechnology Group meetings in the late 1980s), and that 9/11 was just a taste of things to come. Accordingly, the Lifeboat Foundation was incorporated within months of 9/11.

NASA designs nuclear asteroid deflector

Posted by in categories: asteroid/comet impacts, existential risks, lifeboat, space

NASA’s Marshall Space Flight Center has designed a nuclear-warhead-carrying spacecraft, that would be boosted by the US agency’s proposed Ares V cargo launch vehicle, to deflect asteroids.

The Ares V launch vehicle is scheduled to first fly in 2018. It would launch 130 tons to LEO.

I welcome this study for providing a clearer analysis of the deflection options and the analyzing costs of searching for threatening asteroids.

The 8.9m (29ft)-long “Cradle” spacecraft would carry six 1,500kg (3,300lb) missile-like interceptor vehicles that would carry one 1.2MT B83 nuclear warhead each, with a total mass of 11,035kg.

Decisive, immediate action can reduce Pandemic Deaths

Posted by in categories: biological, defense, existential risks, lifeboat

Cities that quickly closed schools and discouraged public gatherings had fewer deaths from the great flu pandemic in 1918 than cities that did not, researchers reported on Monday. Experts agree that a pandemic of some virus, most likely influenza, is almost 100 percent certain. What is not certain is when it will strike and which virus it will be.

In Kansas City, no more than 20 people could attend weddings or funerals. New York mandated staggered shifts at factories. In Seattle, the mayor told people to wear face masks.

No single action worked on its own, the researchers found, it was the combination of measures that saved lives. Peak death rates can be 50% to eight times lower. St. Louis authorities introduced “a broad series of measures designed to promote social distancing” as soon as flu showed up. Philadelphia downplayed the 1918 flu.

Philadelphia ended up with a peak death rate of 257 people per 100,000 population per week. St. Louis had just 31 per 100,000 at the peak.

China, Indonesia, India, Japan and the US most vulnerable to asteroids

Posted by in categories: asteroid/comet impacts, defense, existential risks, lifeboat, space

Using maps of population density, the researchers charted the places likely to suffer the most casualties from asteroids. As might be expected, countries with large coastal populations turned out to be most vulnerable, with China, Indonesia, India, Japan and the US in the top five spots.

The team focused on smaller asteroids because they hit the Earth more frequently. An asteroid a few hundred metres across hits the planet about once every 10,000 years, on average, while those larger than 1 kilometre hit only every 100,000 years or so. Small asteroids are also harder to spot. They considered a range of impact energies corresponding to asteroids between 100 and 500 metres across, striking with typical solar system speeds of about 20,000 kilometres per second.


Simulations show the asteroid impact locations that would produce the most casualties in red. The Pacific coast of Asia is a particularly deadly place for an asteroid to strike because of tsunamis, while a direct strike on some densely populated inland areas could also cause a heavy toll (Illustration: Nick Bailey et al/University of Southampton)

The US faced the worst potential economic losses, since it has a lot of infrastructure on coastlines facing two different oceans. China was second, followed by Sweden, Canada, and Japan.

Sergio Tarrero Joins Lifeboat Foundation Staff

Posted by in category: lifeboat

We welcome one of our most generous donors, Sergio M.L. Tarrero, to the Lifeboat Foundation staff as our International Director of Audiovisual Communications. Mr. Tarrero is currently working on a documentary on existential risk. His bio begins as follows:

Sergio Martínez de Lahidalga Tarrero, BSc, is a screenwriter and filmmaker deeply concerned with the institutionally mediated transmission of socially corrosive beliefs, thoughts, and behaviors. His abiding interest in the forces that drive people apart, particularly those deriving from religious doctrine, inspired him from a young age to ponder what it would take to move people to embrace the primacy of rational thinking over enculturated dogma. In Sergio’s view, an important idea to disseminate widely is that an ethical and contemplative life does not depend on theological postulates.

Read his whole bio here. In a world where the audiovisual medium is one of the most tangible and memorable forms of communication, Sergio’s filmmaking skills will contribute invaluably to the Lifeboat Foundation’s core mission.

2007 DARPA Military Technology Plan: Future Medical Promise or Danger?

Posted by in categories: biological, biotech/medical, defense, lifeboat, robotics/AI

DARPA (the defense advanced research projects agency) is the R&D arm of he US military for far-reaching future technology. What most people do not realize is how much revolutionary medical technology comes out of this agency’s military R&D programs. For those in need of background, you can read about the Army & DARPA’s future soldier Landwarrior program and its medtech offshoots as well as why DARPA does medical research and development that industry won’t. Fear of these future military technologies runs high with a push towards neural activation as a weapon, direct brain-computer interfaces, and drones. However, the new program has enormous potential for revolutionary medical progess as well.

It has been said technology is neutral, it is the application that is either good or evil. (It is worth a side-track to read a discussion on this concept)

The Areas of Focus for DARPA in 2007 and Forward Are:

United States unwilling to spend $300 million for asteroid location

Posted by in categories: asteroid/comet impacts, defense, existential risks, lifeboat, space

NASA estimates the cost to find at least 90 percent of the 20,000 potentially hazardous asteroids and comets by 2020 would be about $1 billion, according to a report NASA will release later this week. It would cost $300 million if a asteroid locating telescope was piggybacked on another vehicle. The report was previewed Monday at a Planetary Defense Conference in Washington.

The agency is already tracking bigger objects, at least 3,300 feet in diameter, that could wipe out most life on Earth, much like what is theorized to have happened to dinosaurs 65 million years ago. But even that search, which has spotted 769 asteroids and comets — none of which is on course to hit Earth — is behind schedule. It’s supposed to be complete by the end of next year.

A cheaper option would be to simply piggyback on other agencies’ telescopes, a cost of about $300 million, also rejected, Johnson said.

Lasers to detect and deflect asteroids

Posted by in categories: asteroid/comet impacts, defense, existential risks, lifeboat, space

Graduate student (University of Alabama Huntsville) Blake Anderton wrote his master’s thesis on “Application of Mode-locked lasers to asteroid characterization and mitigation.” Undergraduate Gordon Aiken won a prize at a recent student conference for his poster and presentation “Space positioned LIDAR system for characterization and mitigation of Near Earth Objects.” And members of the group are building a laser system “that is the grandfather of the laser that will push the asteroids,” Fork said.

Anderton’s mode locked lasers could characterize asteroids up to 1 AU away (1.5 × 10 to the 11 meters). Arecibo and other radar observatories can only detect objects up to 0.1 AU away, so in theory a laser would represent a vast improvement over radar.

A one page powerpoint describes their asteroid detection and deflection approach About 12 of the 1AU detection volumes (around the sun in the asteroid belt) would be needed to cover the main areas for near earth asteroids.

40KW femtosecond lasers could deflect an asteroid the size of Apophis (320meters, would hit with 880 megaton force) given one year of illumination and an early start in the trajectory.

Asteroid shield related: deflection mission and other proposals

Posted by in categories: asteroid/comet impacts, existential risks, lifeboat, space

A giant asteroid named Apophis has a one in 45,000 chance of hitting the Earth in 2036. If it did hit the earth it could destroy a city or a region. A slate of new proposals for addressing the asteroid menace was presented today at a recent meeting of the American Association for the Advancement of Science in San Francisco.

One of the Lifeboat Foundation projects is an Asteroid Shield and the issues and points discussed are in direct alignment with Lifeboat. The specific detection and deflection projects are in the Lifeboat Asteroid Shield project.

Edward Lu of NASA has proposed “gravitational tractor” is a spacecraft—up to 20 tons (18 metric tons)—that it could divert an asteroid’s path just by thrusting its engines in a specific direction while in the asteroid’s vicinity.

Scientists also described two massive new survey-telescope projects to detect would-be killer asteroids.
