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.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
