The Defense Advanced Research Project Agency, that secretive band of Pentagon geeks that searches obsessively for the next big thing in the technology of warfare, is 50 years old. To celebrate, DARPA invited Vice President Dick Cheney, a former Defense Secretary well aware of the Agency's capabilities, to help blow out the candles. "This agency brought forth the Saturn 5 rocket, surveillance satellites, the Internet, stealth technology, guided munitions, unmanned aerial vehicles, night vision and the body armor that's in use today," Cheney told 1,700 DARPA workers and friends who gathered at a Washington hotel to mark the occasion. "Thank heaven for DARPA."

Created in the panicky wake of the Soviets' launching of Sputnik, the world's first satellite, DARPA's mission, Cheney said, is "to make sure that America is never again caught off guard." So, the Agency does the basic research that may be decades away from battlefield applications. It doesn't develop new weapons, as much as it pioneers the technologies that will make tomorrow's weapons better.

So what's hot at DARPA right now? Bugs. The creepy, crawly flying kind. The Agency's Microsystems Technology Office is hard at work on HI-MEMS (Hybrid Insect Micro-Electro-Mechanical System), raising real insects filled with electronic circuitry, which could be guided using GPS technology to specific targets via electrical impulses sent to their muscles. These half-bug, half-chip creations - DARPA calls them "insect cyborgs" - would be ideal for surveillance missions, the agency says in a brief description on its website.
