NASA’s Ion Thruster Sets Continuous Operation Record

NASA

cylonlover writes “NASA’s Evolutionary Xenon Thruster (NEXT) ion engine has set a new world record by clocking 43,000 hours of continuous operation at NASA’s Glenn Research Center’s Electric Propulsion Laboratory. The seven-kilowatt thruster is intended to propel future NASA deep space probes on missions where chemical rockets aren’t a practical option. The NEXT is one of NASA’s latest generation of engines. With a power output of seven kilowatts, it’s over twice as powerful as the ones used aboard the unmanned Dawn space probe, yet it is simpler in design, lighter and more efficient, and is also designed for very high endurance. Its current record of 43,000 hours is the equivalent of nearly five years of continuous operation while consuming only 770 kg (1697.5 lbs) of xenon propellant. The NEXT engine (PDF) would provide 30 million newton-seconds of total impulse to a spacecraft. What this means in simple terms is that the NEXT engine can make a spacecraft go (eventually) very far and very fast.”

AMD

MojoKid writes “AMD has just released some preliminary information regarding the company’s upcoming Radeon HD 8000M series of mobile GPUs. Based on the naming convention alone, it may obvious that the Radeon HD 8000M series is AMD’s second generation of products featuring the GCN (Graphics Core Next) architecture, which debuted in the Radeon HD 7000 series. Like its predecessors, the Radeon HD 8000M series targets gamers with full DirectX 11.1 support and improved gaming performance over the previous-gen, but the architecture also lends itself to GPU compute applications as well. The Radeon HD 8500M sports 384 Stream Processors with an Engine Clock up to 650MHz. Memory clocks will vary based on the use of GDDR3 or GDDR5 memory. The Radeon HD 8600M is essentially the same, but with a slightly higher Engine Clock up to 775MHz. The Radeon HD 8700M is also based on the same GPU, but will be clocked at up to 850MHz, for a further increase in performance over the 8600M. The Radeon HD 8800M series, however, is based on a larger, more powerful chip and will sport 640 Stream Processors with an engine clock of up to 700MHz. GDDR5 memory will be used exclusively with 8800M, at speeds up to 1125MHz. It will be interesting to see how these new GPUs stack up versus NVIDIA’s latest GeForce 600M series of mobile chips.”

F-16 Engines Stolen From Israeli Air Base

The Military

Hugh Pickens writes writes “Defense Tech reports that several F-16 engines weighing 3,700 pounds each have been stolen from a base in a central part of the country as Israeli officials played down the loss saying the engines were old or retired and likely stolen for scrap. US security and aviation experts contacted were not so dismissive of the missing engines and said that some countries would see value in having them and taking them apart. ‘They’re still more modern than anything in the Iranian air force inventory, and they would even be helpful to China in their jet engine development,’ says Richard Aboulafia noting that modern technology engine design remains ‘a black art’ and that competitors would love the opportunity to study them. This is not the first time jet engines have gone missing. In June 2011, Israel reported the loss of eight F-15 and F-16 fighter engines from a base at Tel Nof near Jerusalem when investigators found the engines had been taken away on large trucks, prompting speculation that the thieves had help from inside the base. In 2009, two F-5 engines were stolen from an airbase in Malaysia, tracked to Argentina and ultimately located in Uruguay.”

HydroICE Project Developing a Solar-Powered Combustion Engine

Power

cylonlover writes “OK, first things first – stop picturing a car with solar panels connected to its engine. What Missouri-based inventors Matt Bellue and Ben Cooper are working on is something a little different than that. They want to take an internal combustion engine, and run it on water and solar-heated oil instead of gasoline. That engine could then be hooked up to a generator, to provide clean electricity. While that may sound a little iffy to some, Bellue and Cooper have already built a small-scale prototype.”

First Person Shooters (Games)

dotarray writes “Valve’s Gabe Newell has confirmed that they are building the Source 2 engine, but haven’t yet had the game to roll it out with. From the article: ‘If you’re not smiling yet, you’ll definitely be doing so after you hear how the announcement was made. It was Gabe Newell’s birthday on November 3rd, and 4Chan’s /v/ (videogames) board decided to pay him a surprise visit. In addition to an enormous birthday card signed by many of /v/’s regulars, they also gave him an an actual Mann-Co crate, which he had to pay $2.50 to unlock in order to receive the gift of a combat helmet similar to the one worn by the Team Fortress 2 soldier. Irony at its best.’”

Building Babbage’s Analytical Engine

Technology

An anonymous reader writes “Anybody think 3-D printing technology will have enough moxie to pull off a construction of Babbage’s analytical engine by 2021, the 150th anniversary of Babbage’s passing? The Guardian reports, ‘Plan 28 – named after one set of Babbage’s plans – has assembled the leading technical experts on his designs and just started fundraising. The first stage of the project involves studying the thousands of pages of handwritten notes that Babbage left behind, to determine what exactly needs to be built. Once the study is complete, we’ll be building a 3D physical computer simulation of the analytical engine to verify that his design is workable. Reaching that stage is likely to cost about £250,000. Only once the feasibility of building the machine has been established will the much larger fundraising effort needed for the actual construction to begin. But what we hope to do is create a working monument to the man who conceived the computer, and to inspire today’s scientists and engineers to dream a century into their future.’”

DRM

Via the H comes news of a possible remote attack vector using the protocol handler installed by Valve’s Steam platform: “During installation, it registers the steam:// URL protocol which is capable of connecting to game servers and launching games … In the simplest case, an attacker can use this to interfere with the parameters that are submitted to the program. For example, the Source engine’s command line allows users to select a specific log file and add items to it. The ReVuln researchers say that they successfully used this attack vector to infect a system (PDF) via a batch file that they had created in the autostart folder. … In the even more popular Unreal engine, the researchers also found a way to inject and execute arbitrary code. Potential attackers would, of course, first have to establish which games are installed on the target computer. “

Transportation

walterbyrd writes “The Nano is currently powered by a 37 hp two-cylinder engine and lacks common safety features such as power steering, traction control and airbags. It was originally designed to compete in the Indian market against scooters and motorcycles. . . Along with added safety equipment, it’s likely the car will get a larger, less polluting engine for export markets. Unfortunately, that means the price will increase, as well, possibly tripling by the time it goes on sale in the U.S..”

Transportation

amkkhan writes with this excerpt from International Science Times: “Scientists aiming to create a car that can break 1,000 mph cleared a large hurdle yesterday when they successfully tested their rocket engine. The engine will power the supersonic car known as the Bloodhound SSC — meant to become the fastest car in the world. The British team tested the engine in an aircraft shelter in Newquay Cornwall Airport, originally designed to protect fighter planes from bombs. Although the data hasn’t fully been analyzed, the researchers said the engine reached 30,000 horsepower during the 10-second burn. Given enough time, they expect the engine to reach 80,000 horsepower and 27,500 pounds of thrust.”
