A prototype of a spacecraft planned as a 'lifeboat' for crews on the International Space Station passed a major milestone. The wingless X-38, the first new U.S. spacecraft developed in more than 20 years, successfully made its maiden unpiloted flight test. The nine-minute flight of the atmospheric test vehicle took place at NASA's Dryden Flight Research Center in California. The vehicle dove from the wing of a B-52 bomber at 23,000 ft. A series of parachutes slowed its descent. Then a 5,500-sq-ft parafoil--a steerable parachute--billowed out. The X-38 floated to a touchdown on its skids. The craft is the first of several increasingly detailed X-38s being built to test technology for a six-person "crew return vehicle." The X-38 has no engines. It uses the aerodynamic shape of the vehicle to provide the lift that airplanes get from their wings. In 2000, a space shuttle will carry a larger version of the X-38 into orbit. From there it is to plunge back to Earth for a practice landing.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
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.
