  • DARPA’s Falcon Hypersonic Technology Vehicle 2 (HTV-2) program is a multiyear research and development effort to increase the technical knowledge base and advance critical technologies to make long-duration hypersonic flight a reality.

    Data from the program informs policy, acquisition, and operations decisions for future Department of Defense Conventional Prompt Global Strike programs. Hypersonic data is collected through extensive modeling and simulation, wind-tunnel testing and two experimental flight tests. The ultimate goal is a capability that can reach anywhere in the world in less than an hour.

    Falcon HTV-2 is an unmanned, rocket-launched, maneuverable aircraft that glides through the Earth’s atmosphere at incredibly fast speeds—Mach 20 (approximately 13,000 miles per hour). At HTV-2 speeds, flight time between New York City and Los Angeles would be less than 12 minutes. The HTV-2 vehicle is a “data truck” with numerous sensors that collect data in an uncertain operating

  • By the time you finish reading this sentence, the Falcon HTV-2, the fastest plane ever built, could have flown 18 miles. It would get from London to Sydney in less than an hour, while withstanding temperatures of almost 2,000C, hotter than the melting point of steel.

    At 3pm BST on Thursday , the US Defence Advance Research Projects Agency will launch the Falcon Hypersonic Technology Vehicle 2 on the back of a rocket from the Vandenberg Air Force Base in California. If all goes to plan, engineers will launch the Falcon HTV-2 to the edge of space, before detaching the plane and guiding it on a hypersonic flight that will reach speeds of 13,000mph (about 20 times the speed of sound) on its return to Earth.

  • Many of the new TLDs are accepting registrations. Go to the InterNIC website for more information.


    The Internet's domain-name system (DNS) allows users to refer to web sites and other resources using easier-to-remember domain names (such as "") rather than the all-numeric IP addresses (such as "") assigned to each computer on the Internet. Each domain name is made up of a series of character strings (called "labels") separated by dots. The right-most label in a domain name is referred to as its "top-level domain" (TLD).

    The DNS forms a tree-like hierarchy. Each TLD includes many second-level domains (such as "icann" in ""); each second-level domain can include a number of third-level domains ("www" in ""), and so on.

  • The following is a list of frequently asked questions (FAQs) about the new top-level domains (TLDs) that are being introduced to the Internet. This list will be updated frequently; please check back often.
  • Welcome to the New Internet — an Internet where you control your own name space and how it is used.

    For the first time in history, the Internet Corporation for Assigned Names and Numbers (ICANN) is giving you the opportunity to create your own domain ending, opening up the Internet to all interested parties so they can:

    Control what appears to the left and right of the dot
    Create a lasting brand that only you control
    Create a unique global identity
