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:

1. Chip-Scale Atomic Clock
2. Global War on TerrorismUnmanned Air Vehicles
3. Militarization of Space
4. Supercomputer Systems
5. Biological Warfare Defense
6. Prosthetics
7. Quantum Information Science
8. Newton’s Laws for Biology
9. Low-Cost Titanium
10. Alternative Energy
11. High Energy Liquid Laser Area Defense System

the potential for the destructive use of these technologies is obvious, for a a complete review of these projects and the beneficial medical applications of each visit docinthemachine.com

A valuable paper by Jason Matheny of the University of Maryland is “Reducing the Risk of Human Extinction”. The abstract is as follows:

In this century a number of events could extinguish humanity. The probability of these events may be very low, but the expected value of preventing them could be high, as it represents the value of all future lives. We review the challenges to studying human extinction risks and, by way of example, estimate the cost-effectiveness of preventing extinction-level asteroid impacts.

A better atomic force microscope from Japan:

“A new type of atomic force microscope (AFM) has been developed that can “fingerprint” the chemical identity of individual atoms on a material’s surface. This is one step ahead of existing AFMs, which can only detect the position of atoms. The device determines local composition and structure using a precise calibration method, and can even be used to manipulate specific atomic species. The team demonstrated their “fingerprinting” technique by using an atomic force microscope (AFM) to distinguish atoms of tin (blue) and lead (green) deposited on a silicon substrate (red).”

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.

Here is a piece of news from early last month, via CNN:

WASHINGTON (AP) — Hackers briefly overwhelmed at least three of the 13 computers that help manage global computer traffic Tuesday in one of the most significant attacks against the Internet since 2002.

Experts said the unusually powerful attacks lasted for hours but passed largely unnoticed by most computer users, a testament to the resiliency of the Internet.

From Physorg.com:

With a typical launch cost for a spaceship around $20 million, it’s difficult to practically conceive of a space industry beyond federally funded agencies. Nevertheless, many people believe that expanding space travel—whether for research purposes, entertainment, or even colonization—is not impractical. Bridging the economic hurdle may be technologies such as the maglev launch assist. According to an analysis, the cost of launching payloads into the low earth orbit with maglev may be achieved with only hundreds of dollars per pound (John Olds and Peter Bellini).

Most recently, researchers in a group including Wenjiang Yang and his colleagues from the Beijing University of Aeronautics and Astronautics and the Chinese Academy of Sciences have investigated the possibility of the “Maglifter,” a maglev launch assist vehicle originally proposed in the 1980s. In this system, a spaceship would be magnetically levitated over a track and accelerated up an incline, lifting off when it reaches a velocity of 1,000 km/hr (620 miles/hr). The main cost-saving areas would come from reduced fuel consumption and the reduced mass of the spaceship.

“The importance of the space sector can be emphasized by the number of spacecrafts launched. In the period from 1957 till 2005, 6376 spacecraft have been launched at an average of 133 per year. The has been a decrease in the number of spacecrafts launched in the recent years with 78 launched in 2005. Of the 6378 launches, 56.8% were military spacecrafts and 43.2 were civilian. 245 manned missions have been launched in this period. 1674 communication or weather satellites were also launched. The remaining spacecraft launches has been exploration missions.”

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.

The Ballistic Missile Early Warning Radar System (BMEWS) at Fylingdales, U.K.

The ongoing debate on the proposed missile defense shield in Europe is heating up. Poland and the Czech Republic are among the possible sites and the UK is now showing interest in supporting the missile shield. Fears over the destabilising effects of such a shield was confirmed by a Russian general who said that they would target the system.

Vladimir Putin, Russia’s president, said America would trigger an “inevitable arms race” if it deployed interceptors in Europe to knock ballistic missiles out of the sky. A senior Russian general rumbled that Russian missiles would target any interceptors in eastern Europe. Poland’s prime minister told his people that Russia was trying to “scare” them. The Czech foreign minister (a prince with a splendid moustache) complained of Russian “blackmail”.

“The aim is to break ground on a European site in 2008, and for its interceptors to become operational in 2012. This week the Polish and Czech prime ministers said they were keen on hosting the missile-defence sites. That is a change: talks with the Poles have dragged on for years, thanks to elaborate Polish demands for things such as extra missile defences for their own country. Yet both Mr Blair and his Polish rivals face objections from three sources: from Russia, from many of their own voters and from fellow European leaders.”
