It can already compete successfully with chemical thrusters, especially for attitude control, orbit transfer and/or orbital station-keeping as well as for the main propulsion system for deep space missions. However, xenon, the propellant of choice in most EP devices, has a substantial drawback: its cost is very high. On the basis of the experience with plasma jet accelerators, a team of scientists and engineers from Poland has designed the Hall effect thruster optimised to work with krypton, a much more affordable noble gas.

An airplane's digital flight-data recorder, or "black box," holds massive amounts of data, documenting the performance of engines, cockpit controls, hydraulic equipment and GPS systems, typically at regular one-second intervals throughout a flight. Inspectors use such data to reconstruct the final moments of an accident, looking for telltale defects that may explain a crash. More recently, analysts have probed black-box data in an effort to prevent such accidents from ever occurring. Using software tools that can rapidly search data, operators can flag problem areas and determine whether a plane needs to be pulled off the line to be physically inspected, or if there are problems with flight procedures.

Researchers from Germany are developing procedures and methods to automate assembly processes to continuously improve the quality of the engines. The use of the latest technologies helps to eliminate uncertainties during engine assembly.

Proving that these automated systems will work as intended is a daunting task, but computer scientists have now demonstrated it is possible to verify the safety of these highly complex systems.

These statistics make traffic accidents one of the leading causes of death in this country, as well as worldwide. More progress must be made to achieve the long-term goal of "intelligent transportation": cars that can "see" and communicate with other vehicles on the road, making them able to prevent crashes virtually 100 percent of the time.

Many surprises are likely awaiting the spacecraft. Fri, 10 Jun 2011 09:45:45 EDT http://www.sciencedaily.com/releases/2011/06/110610094511.htm
