Boeing Electronic Dynamic Devices (www.boeing.com) has won three NASA contracts for advanced xenon ion propulsion technologies. The projects include the NASA evolutionary xenon thruster system, the carbon-based ion optics project, and the high-power electric propulsion project. Designs developed and demonstrated in these programs in the next two and a half years will become the critical technologies in the development of very high power (100 to 250 kW) nuclear electric propulsion systems for future deep space missions.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
