DARPA'S HTV-2 FAILS

The prototype Hypersonic Technology Vehicle (HTV-2) failed its second test flight after having failed the first one. The HTV-2 disappeared without a trace during the first flight. A video of the second failed flight has been released.

The HTV-2 is an unmanned, experimental aircraft that is designed to drop a bomb anywhere in the world. A Minotaur IV Lite launch vehicle takes the HTV-2 into space and releases it. The HTV-2 then reenters the atmosphere and follows a path until it lands in the ocean. Its top speed is Mach 20, twenty times the speed of sound. To give a sense of how fast the HTV-2 is, it can fly from Los Angeles to New York City in less than 12 minutes.

The HTV-2′s first test flight occurred last year. The flight lasted nine minutes before DARPA lost contact with the aircraft. Despite the failure, the test flight proved that the HTV-2 is capable of flying 3.6 miles per second while maintaining GPS signals.

The second test flight occurred on August 11 of this year. The flight lasted nine minutes before DARPA lost contact with the aircraft following the glide phase. DARPA had 22 stations set up along the HTV-2′s flight path to collect data.

DARPA CREATING 'VIRTUAL FIRING RANGE' TO HELP COMBAT CYBER ATTACKS

Reuters reports that DARPA is working on a National Cyber Range, which would act a standalone internet simulation engine where digital warriors can be trained and experimental ideas tested out. Lockheed Martin and Johns Hopkins University are competing to provide the final system, with one of them expected to soon get the go-ahead for a one-year trial, which, if all goes well, will be followed by DARPA unleashing its techies upon the virtual firing range in earnest next year.

The cost of the project is said to run somewhere near $130 million, which might have sounded a bit expensive before the recent spate of successful hacking attacks on high profile private companies, but now seems like a rational expenditure to ensure the nuclear missile codes and the people crazy enough to use them are kept at a safe distance from one another.

NEW BRAIN CONTROLLED ROBOTIC ARM PROSTHETIC HITS FDA

The FDA has just announced a new "Innovation Pathway" program that promises to allow for priority reviews of "truly pioneering technologies," which could potentially cut the approval process time in half. Somewhat ironically, however, that program itself will first need some further review before it's broadly deployed, but the FDA has already kicked things off on a limited basis with its first submission: a brain-controlled robotic arm from DARPA. It's not clear which arm that is, but it sounds a lot like the now-famous "Luke" arm (pictured above) developed by Dean Kamen's Deka organization, which just so happens to be funded by DARPA
