Boeing has joined a small group of technology bigwigs trying to test a theory that would let engineers negate some of the effects of gravity. The American aerospace giant is using the work of controversial Russian scientist Yevgeny Podkletnov, who claims to have developed a device that can shield objects from the Earth’s pull. Other researchers claim Podkletnov’s work is hokum, but considering the cost savings such a device would represent for air travel, Boeing seems intent on getting to the bottom of it all. The Russian says he found that objects above a superconducting ceramic disc rotating over powerful electromagnets lost weight, the BBC reports. “The reduction in gravity was small, about 2 percent, but the implications — for example, in terms of cutting the energy needed for a plane to fly — were immense.”
Stargazers this week may be surprised by the sight of a glowing orange object streaking across the night sky. It?s the International Space Station, which is making bright passes over the U.S. and Canada until mid-August. The ISS — which travels at 17,000 mph and circles the planet 16 times a day — crosses the sky in three to six minutes, and can shine more brightly than any planet or star except our sun and moon. (Its brightness depends on its orientation, your location and the sun.) Right now this impressive sight can be observed by the unaided eye if skies are clear. (A flyby near downtown Los Angeles on Wednesday night was clearly visible despite city lights.) To find out when the station will fly above your town, orbit over to NASA SkyWatch.
Wired.com carries a gee-whiz tale from the Office of Naval Research on development of an army of drones that would fight the battles of tomorrow. It all sounds very Star Wars — and expensive. But the notion is that human commanders at the top would provide goals that a network of unmanned but highly-networked machines would work to achieve. That could be taking a hill in a combat zone, capturing a known enemy, or helping rescue disaster victims. One wonders who such an army would fight (the Chinese army of 2020? A resurgent Russia?) But maybe this will be one of those ideas that die on the vine in the armed services but find a robust future in the private sector. The original technology, after all, came from drones built to track migrating whales.
