Dick "Spe" Spehalski leads the engineers who designed the most complex interplanetary spacecraft ever created: Cassini. The spacecraft--including its orbiter and Huygens probe to the moon Titan--is currently winging its way towards a rendezvous with Saturn in 2004. But for five years prior to its October '97 launch, Spehalski championed the mission past cancellation threats by cutting weight, lowering power requirements, and putting the project back on track. And when it came to resolving complex engineering issues with the project's 16 international partners, Spehalski was the man everyone turned to. This isn't the first time NASA tapped him to lead one of the agency's flagship programs; he also served as project manager for the Galileo mission to Jupiter. Following a term as project manager for the Space Infrared Telescope Facility, Spehalski retired in June 1998, but not before NASA awarded him its highest honor, the Distinguished Service Medal.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
