Hasta La Gadget!

Lasers destroy missiles, missiles shoot down satellites, and soon, satellites may tell both where to aim, as the United States successfully managed to track an entire ballistic missile launch from “birth-to-death” with its prototype Space Tracking and Surveillance System. After a year and a half in orbit, two Northrop Grumman-built satellites managed the feat last week, in what the company’s calling “the Holy Grail for missile defense.” While we’re not reading about any plans to mount any lasers on the satellite’s… ahem… heads, Space News reports that the US Navy will attempt to relay the satellite tracking data to its Aegis ships with interceptor missiles on board, and hopefully obliterate incoming projectiles with the extra range and reaction time that satellite coordinates afford. The Navy has reportedly scheduled its first game of space-based Missile Command for next month.

US satellites successfully track ballistic missile from cradle to grave, don’t pay for the flowers originally appeared on Engadget on Fri, 25 Mar 2011 09:46:00 EDT. Please see our terms for use of feeds.

This definitely isn’t the first time we’ve heard of wearable solar cells, but a new development underway in the UK could certainly have a greater impact than, say, an iPod-charging denim jacket. By combining photovoltaic cells with thermoelectric devices, a team of researchers is working to create new, more efficient uniforms for British troops. The solar-powered outfits could cut the weight of traditional battery packs in half, allow for significantly longer military missions, and actually absorb energy across the electromagnetic spectrum, decreasing the possibility of detection by infrared technology. To ensure 24-hour power, the solar cells will collect energy in daylight, with thermoelectric devices taking on the task at night. A prototype is set for 2013, but we wonder how long it will take to hit the catwalk.

If we referred to an Apple or Android army, you might assume we’re talking about a legion of brand-loyal fanboys, with which most Engadget commenters are intimately familiar. Defense contractors, however, are trying to turn the US Army into a lethal Apple / Android force with soldier-centric apps. Harris Corp. has a tablet app in the works that allows soldiers to control IP cameras on UAVs for more pertinent intel on the ground while simultaneously sending that information to command centers anywhere in the world. Meanwhile, Intelligent Software Solutions aims to bring mapping mashups to the battlefield (no purpose-built device needed) with an app that combines smartphones’ geolocation with historical data to show troops what’s been going down in the area — from IED explosions to insurgent arrests. Best of all, these apps lower training costs since most warriors are already fluent in Android or iOS and the consumer handhelds can be cheaply ruggedized to replace the more robust $10,000 units in the field today. Should protective measures fail, the devices’ (relatively) low replacement cost makes them “almost disposable.”

Apple and Android get drafted, soldier-centric Army apps coming soon originally appeared on Engadget on Thu, 17 Mar 2011 02:34:00 EDT. Please see our terms for use of feeds.

Hervey Stockman passed away today, leaving behind a legacy as the first man to pilot a dedicated spy plane in Soviet airspace. Taking the Lockheed U-2 into Communist territory in the middle of the Cold War, Stockman was able to collect data on the USSR while evading MiGs trying to intercept him. Stockman also happened to be the uncle of Giz reader Willy Pell, who has graciously shared some personal anecdotes told to him by Stockman. More »

In the “so-futuristic-it-hurts” category, Princeton engineers have come up with a way to create a laser beam out of thin air. Their method, published in the journal Science yesterday, uses a focused laser pulse which causes another beam to be created from the air, carrying fingerprints of any molecules it encounters to a receiver. The effect comes from the first laser energizing oxygen atoms in a specific area and, as they cool, causing them to release infrared light, exciting more atoms and amplifying the process.
