Title: US Hypersonic Glider Launched

US Hypersonic Glider Launched


An experimental unmanned hypersonic glider has been launched from an air base on the central California coast.

The U.S. Defense Advanced Research Projects Agency used Twitter to announce the launch Thursday from Vandenberg Air Force Base 130 miles northwest of Los Angeles.

A rocket carried the agency's Falcon Hypersonic Technology Vehicle-2 to the edge of space, where it separated from the booster to maneuver through the atmosphere at 13,000 mph. Minutes into the flight, the agency said the mission was on track in its glide phase. The mission will end with a plunge into the ocean.

A similar vehicle was launched last year and returned nine minutes of data before contact was prematurely lost.

The U.S. military is trying to develop technology to respond to threats around the globe at speeds of Mach 20 or greater.

Sounds cool but apparently they lost it.

U.S. hypersonic glider launched, contact lost
By John Antczak, Associated Press

LOS ANGELES — An unmanned hypersonic glider developed for U.S. defense research into super-fast global strike capability was launched atop a rocket early Thursday but contact was lost after the experimental craft began flying on its own, the Defense Advanced Research Projects Agency said.

The problem occurred during the critical point of transition to aerodynamic flight, DARPA said in a statement that described the mission as an attempt to fly the fastest aircraft ever built.
"More than nine minutes of data was collected before an anomaly caused loss of signal," it said. "Initial indications are that the aircraft impacted the Pacific Ocean along the planned flight path."

DARPA HYPERSONIC VEHICLE ADVANCES TECHNICAL KNOWLEDGE

HTV-2 collects unique data during several phases of second flight

Today, DARPA attempted to fly the fastest aircraft ever built.  The Agency’s Falcon Hypersonic Technology Vehicle 2 (HTV-2) is designed to fly anywhere in the world in less than 60 minutes.  This capability requires an aircraft that can fly at 13,000 mph, while experiencing temperatures in excess of 3500F.  The second test flight began with launch at 0745 Pacific Time.  The Minotaur IV vehicle successfully inserted the aircraft into the desired trajectory.  Separation of the vehicle was confirmed by rocket cam and the aircraft transitioned to Mach 20 aerodynamic flight.  This transition represents a critical knowledge and control point in maneuvering atmospheric hypersonic flight.  More than nine minutes of data was collected before an anomaly caused loss of signal.  Initial indications are that the aircraft impacted the Pacific Ocean along the planned flight path.
