Improving security with face recognition technology
A number of U.S. states now use facial recognition technology when issuing drivers licenses. Similar methods are also used to grant access to buildings and to verify the identities of international travelers. Historically, obtaining accurate results with this type of technology has been a time intensive activity. Now, a researcher from the University of Miami College of Engineering and his collaborators have developed ways to make the technology more efficient while improving accuracy.
LaserMotive is First Ever Prize Winner in Space Elevator Games
The LaserMotive machine consists of a motor that pulls the device up the 2,953-foot-long ribbon, photovoltaic cells that power the motor, and a ground-based laser that provides the light for the cells. LaserMotive set a new record for the competition, and became the first team to ever reach the top of the ribbon.
Boeing Prepares Wedgetail For Delivery

Software prevents fatal crashes, scientists say
Every year, one or two pilots die because they couldn’t get their bearings in time. Now, scientists for the Air Force and Lockheed Martin Corp. think they can virtually eliminate those fatal accidents with onboard computer software that takes control of the Fighting Falcon when it goes into a deadly dive.

Boat tail reduces truck fuel consumption by 7.5 percent
A boat tail is a tapering protrusion about two metres in length mounted on the rear of a truck. The boat tail had already proved itself during wind tunnel experiments and computer simulations, both conducted at Delft University of Technology (The Netherlands; TU Delft), in theory and using small-scale models.

Walrus Heavy-Lift Blimp
The Walrus program aimed to develop and evaluate a very large airlift vehicle concept designed to control lift in all stages of air or ground operations including the ability to off-load payload without taking on-board ballast other than surrounding air. This is obviously rather important when offloading up to 2 million pounds of personnel and military equipment in remote areas.

Space junk piles up into threat to future launches
A BURGEONING blizzard of space debris is going to have a major impact on the future economics of space flight.
That was the prediction made this week by Hugh Lewis of the University of Southampton, UK, at the European Air and Space Conference in Manchester. His projections indicate that the number of close encounters between objects in orbit will rise 50 per cent in the next decade, and quadruple by 2059. Countermeasures will add greatly to the cost of future missions.
