DARPA's HTV-2 Launch Delayed

Launch of the Defense Advanced Research Project Agency’s (DARPA’s) Falcon Hypersonic Test Vehicle-2 (HTV-2) has been delayed because of weather.

This is the second of two Falcon HTV-2 flights (not to be confused with SpaceX’s Falcon launch vehicle or Japan’s HTV cargo spacecraft for the International Space Station). The first was in April 2010. HTV-2 is designed to provide data on hypersonic flight that could lead to development of hypersonic vehicles in the future. The first test flight collected 139 seconds of data in the Mach 22 to Mach 17 range, but DARPA lost contact with the aircraft after nine minutes of flight according to Aviation Week & Space Technology.

The Minotaur IV launch from Vandenberg Air Force Base, CA was delayed today because of poor down-range weather. Another attempt will be made tomorrow between 7:00 am and 1:00 pm PDT.
