The Soviet Union launched the very first earth-orbiting satellite in 1957, and the world looked on in awe as Sputnik flashed through the sky. Fifty years later, you’d be lucky to see anything. The U.S. Space Surveillance Network says there are almost 20,000 man-made objects in orbit, ninety-four percent of which are non-functional debris. And that’s not counting the hundreds of thousands of bits of junk too small to track. Little wonder the Defense Advanced Research Projects Agency (DARPA) has put out a call for someone – anyone – to come up with a way to effectively remove orbital debris. Read More
Not long ago we brought you an article about a tiny ‘nano air vehicle’ (NAV) that hovers by flapping its wings. Its creator, AeroVironment, has now released a video capturing details of the craft's impressive non-restricted flying capabilities. Read More
In a collaborative effort between the Arizona State University and Technical University of Eindhoven in the Netherlands, researchers have found a way to make optical lasers much smaller than it was previously thought was possible, making dreams of speedier computers and faster Internet access closer to reality than ever before.

Recent technological developments are presenting increasing opportunities for blind and vision impaired people to interact with the world in ways not previously possible. However, many everyday acts we take for granted such as driving a car remain out of reach. That’s well on the way to changing thanks to a development by a team of students at the Virginia Tech University, who have designed a car that allows blind and visually impaired people to take the wheel and drive unassisted.

A tiny nano air vehicle (NAV) that hovers by flapping its wings has impressed its developers – and the Defense Advanced Research Projects Agency (DARPA) - with AeroVironment receiving a Phase II contract extension worth $2.1 million for its NAV program. Since its initial 20-second flight in December 2008, the tiny 10 gram craft, which carries its own power supply, has progressed towards achieving AV's goals of a creating a machine that can hover for extended periods and fly at forward speeds up to 10 meters per second.

Military-funded projects often pave the way for a much better consumer product, and although the original DARPA funding of the development of the Tactical Electric No Signature (TENS) Mountain bike for Marines and paratroopers is now over a decade old, hold onto your hats folks, because the design has been upgraded and will be sold in limited quantities with a 1000 watt propulsion system. The TidalForce M-750 x2.0 is based around the commercially available (and ingenious) Montague Paratrooper folding bike but has a top speed of over 30 mph and range on a single charge is 25 - 28 miles, using the electric power only. The E+ advanced propulsion system features nine forward power modes, nine resistance (exercise) modes, cruise control and anti-theft. It folds to 3 x 3 ft, so it fits in the boot, and the componentry is first class with RockShox Tora 302 Forks, Shimano XTR brakes, FSA Gossamer 30/38/52 tooth crank set, Crane Creek Thudbuster ST seat suspension and a WTB Speed-V Seat. Like we said - highly-desirable. Read More
Boeing plans to have a new unmanned platform based on the X-45C in the air by December 2010. Dubbed Phantom Ray, the internally funded venture will build on the knowledge gained in the shelved X-45 project, which saw the X-45A unmanned aircraft complete 64 flights between 2002 and 2005, achieving a number of milestones including the first precision weapons demonstration by an unmanned combat system and the first autonomous multivehicle flight under the control of a single pilot. Phantom Ray will be based on the larger, fighter-sized, X-45C which appeared at airshows as a full-scale mock-up during 2004. Read More
May 1, 2009 The idea of replacing very expensive space based satellites and Aircraft mounted Airborne Warning And Control Systems (AWACS) with stationary platforms inside Earth's atmosphere has been floated for decades. Despite the fact that lighter-than-air vehicles or airships that could fulfill this role have been flying for over 300 years, the idea is only now getting off the ground. Lockheed Martin has been chosen by the Defense Advanced Research Projects Agency (DARPA) for a US$400 million contract to to design, build, test and fly a 1:3 scale model of an airship surveillance and telecommunications platform called the High Altitude Airship (HAA). The full scale HAA would measure 240 ft long by 70 ft in diameter, run entirely on solar power and be able to stay aloft for up to 10 years. Read More
Can you imagine a world full of large, relatively quiet rotorcraft making short hops between cities such as New York and Washington, carrying as many as 100 passengers at a time in comfort and safety? This, amongst other technological improvements, would require helicopters with greatly improved rotor blade efficiency, allowing them to travel much quieter, smoother and further with the same amount of fuel. NASA is currently conducting research in their wind tunnels on the SMART rotor hub, which has rotor blades made with shape-changing materials that could one day make this scenario a reality.
