Dennis Jenkins, who spent his entire 30-plus year career sending the shuttles into space, is playing a key role in locating essential parts using his own and his colleagues' institutional memory. Employed by NASA contractor Martin Marietta, he helped write the software used in loading and controlling the liquid oxygen needed to launch the 2,250-ton shuttle assembly into low Earth orbit. Now, with the program part of a bygone era of exploration, the 57-year-old works for the California Science Center, helping officials figure out how to rebuild Endeavour." Link to Original Source top
dangle (1381879) writes "In an attempt to prevent future data leaks, Army Gen. Keith B. Alexander, the NSA’s director, has announced plans to cut almost all the agency's system administrators. “What we’re in the process of doing – not fast enough – is reducing our system administrators by about 90 percent,” he said last week at Fordham University in New York. Many of those systems administrators are contractors, like Snowden was. Instead of the 1,000 systems administrators NSA uses, Alexander wants to move more of the operation to the cyber cloud, called the Intelligence Community’s Information Technology Enterprise (ICITE), which relies on a network of computers linked on the Internet. “We’ve put people in the loop of transferring data, securing networks and doing things that machines are probably better at doing,” Alexander said."

dangle (1381879) writes "BAE Systems has developed a positioning solution that it claims will work even when GPS is unavailable. Its strategy is to use the collection of radio frequency signals from TV, radio and cellphone masts, even WiFi routers, to deduce a position. BAE's answer is dubbed Navigation via Signals of Opportunity (NAVSOP). It interrogates the airwaves for the ID and signal strength of local digital TV and radio signals, plus air traffic control radars, with finer grained adjustments coming from cellphone masts and WiFi routers. In any given area, the TV, radio, cellphone and radar signals tend to be at constant frequencies and power levels as they are are heavily regulated — so positions could be calculated from them. "The real beauty of NAVSOP is that the infrastructure required to make it work is already in place," says a BAE spokesman — and "software defined radio" microchips that run NAVSOP routines can easily be integrated into existing satnavs. The firm believes the technology could also work in urban concrete canyons where GPS signals cannot currently reach."

Lab and Sy-Lab have officially released their Free Universal Construction Kit, allowing builders to freely interconnect parts from Lego, K'Nex, Fischertechnik and other common building sets. ZomeTool and Zoob patterns will be available after related patents expire. The makers have also spent considerable effort investigating and anticipating legal complaints from manufacturers, using an Inverse Think of The Children Argument:
Some may express concern that the Free Universal Construction Kit infringes such corporate prerogatives as copyright, design right, trade dress, trademarks or patents of the supported toy systems. We encourage those eager to enforce these rights to please think of the children — and we assert that the home printing of the Free Universal Construction Kit constitutes protected fair use."

dangle (1381879) writes "Technicians were installing a backup power-supply system for the combined Alaska Airlines and Horizon Air computer system this weekend when a transformer malfunctioned, taking down the system around 3 a.m. Saturday, affecting approximately 12,150 passengers through the cancellation of 140 flights, equalling 15% of the airline's scheduled departures on Saturday.
"We're almost pretty much" back to normal following the transformer malfunction, airlines spokeswoman Bobbie Egan said Sunday. "We should be right on track by the end of today."" Link to Original Source top
dangle (1381879) writes "Voyager 2's flight data system, which formats information before beaming it back to Earth, has experienced a hiccup that has altered the pattern in which it sends updates home, preventing mission managers from decoding the science data beamed to Earth from Voyager 2. The spacecraft, which is currently 8.6 billion miles (13.8 billion km) from Earth, is apparently still in overall good health, according to the latest engineering data received on May 1. "Voyager 2's initial mission was a four-year journey to Saturn, but it is still returning data 33 years later," said Voyager project scientist Ed Stone of the California Institute of Technology in Pasadena. "It has already given us remarkable views of Uranus and Neptune, planets we had never seen close-up before. We will know soon what it will take for it to continue its epic journey of discovery." The space probe and its twin Voyager 1 are flying through the bubble-like heliosphere, created by the sun, which surrounds our solar system." Link to Original Source top
dangle (1381879) writes "The Indian Space Research Organisation (ISRO) has determined that higher than anticipated levels of solar radiation led to the premature end of the Chandrayaan-1 mission after 10 months of data collection. "We have learnt some valuable lessons," said Madhavan Nair. In future missions, ISRO would look for devices that are less susceptible to radiation, he added. High levels of solar radiation led to the destruction of the power supply units for two computers on board the spacecraft. This ultimately led to loss of communication to or from the spacecraft. Failure of the primary and redundant star sensors in April and May of this year was also blamed on solar radiation. The spacecraft is hovering 200 kilometers above the moon's surface, and is estimated to impact the moon in about 1,000 days." Link to Original Source top
dangle (1381879) writes "More than 20 million other smartphone users are on the AT&T network, but other phones do not drain the network the way the nine million iPhones users do. Because the average iPhone owner can use 10 times the network capacity used by the average smartphone user, dropped calls, spotty service, delayed text and voice messages and glacial download speeds are the result as AT&T's cellular network strains to meet the demand. AT&T says that the majority of the nearly $18 billion it will spend this year on its networks will be diverted into upgrades and expansions to meet the surging demands on the 3G network. The company intends to erect an additional 2,100 cell towers to fill out patchy coverage, upgrade existing cell sites by adding fiber optic connectivity to deliver data faster and add other technology to provide stronger cell signals. http://www.nytimes.com/2009/09/03/technology/companies/03att.html?hp"
