Submission + - Japan to land unmanned lunar probe in 2018 (astrowatch.net)

Taco Cowboy writes: The Japan Aerospace Exploration Agency (JAXA) is planning to attempt Japan’s first lunar landing in fiscal 2018, sources close to the project said Sunday. JAXA has said it will use unmanned probes to study the possible use of materials on the moon as well as its environment, which could pave the way for future manned missions. JAXA is expected to brief a government panel on the project with the aim of securing funding for mission preparations from the budget for fiscal 2016, which begins next April, the sources said

The lunar probe is likely to be launched on an Epsilon advanced rocket, the sources said

The SLIM mission is aimed at establishing a method for pinpoint landings that would make it possible to approach a target area with a level of accuracy ranging in the hundreds of meters

Submission + - Something Smells: Cities Use High Tech to Investigate Intrusive Odors 1

HughPickens.com writes: Kate Murphy reports at the NYT that local governments are beginning to regulate intrusive and unpleasant smells using high tech devices. If you time-traveled back 200 years or so, you’d likely scrunch up your nose because our forebears threw sewage out their windows, and the primary mode of transport — horses — relieved themselves in the streets. These days 'we have so reduced the level of background odor pollution, we are becoming more sensitive to anything we smell,” says Pamela Dalton, an olfactory researcher at Monell Chemical Senses Center, a nonprofit group in Philadelphia that studies smell and taste. In the past offenders were typically livestock operations and wastewater treatment plants, but more recently odor inspectors are getting calls about smells emanating from ethnic restaurants, coffee roasters and candle and bath shops. In an effort to be objective, a growing number of locales have begun using a device called a Nasal Ranger, which looks like a megaphone for the nose and measures the intensity of smells according to a so-called dilution ratio (PDF). An odor is considered intrusive if the average person can smell it when it is diluted with seven parts clean air — a decades-old threshold of stinky.

New York City received more than 10,000 odor complaints last year, many from residents upset about cooking smells wafting into their apartments from restaurants and coffeehouses — smells that might be pleasing when patronizing those same establishments. “A lot of it has to do with tolerance level in neighborhoods that are getting gentrified,” says Ben Siller. “People at lower socioeconomic levels may tolerate something much better than someone who moves into the same area and buys a house, sinks a fortune into remodeling and then goes out in the backyard and smells a pot grower, charbroiler, pet food manufacturer or something stinky like that.”

Submission + - Hubble turns 25 (hubble25th.org)

Taco Cowboy writes: The Hubble Telescope was launched on April 24, 1990, aboard the Space Shuttle Discovery from Kennedy Space Center, Florida

Currently it is flying about 340 miles over the Earth and circling us every 97 minutes

While the telescope itself is not really much to look at, that silver bucket is pure gold for astronomers

Scientists have used that vantage point to make ground-breaking observations about planets, stars, galaxies and to reveal parts of our universe we didn't know existed. The telescope has made more than 1 million observations and astronomers have used Hubble data in more than 12,700 scientific papers, "making it one of the most productive scientific instruments ever built," according to NASA

The truly spectacular images of the cosmo have also led to a scientific bounty that has far exceeded Hubble’s original goals: measuring how fast the universe is expanding; figuring out how galaxies evolve; and studying the gas that lies between galaxies

NASA aims to keep Hubble operating through at least 2020 so that it can overlap with its successor. The James Webb Space Telescope is due to launch in October 2018 and begin observations in mid-2019

The institute is reviewing scientists’ proposals for telescope time and mulling if some projects merit special attention as Hubble nears its end. Typically, the program receives about five requests for every hour of available telescope time

“There’s clearly there’s no lack of things to do with this observatory in its remaining years. The question is what do we do?” Sembach said at a recent American Astronomical Society meeting in Seattle

Submission + - OSGeo Foundation up in arms over ESRI LAS lock-in plans

Bismillah writes: The Open Source Geospatial Foundation is outraged over mapping giant ESRI's latest move which entails vendor lock-in for light detection and ranging (LiDAR) data through its proprietary Optimised LAS format. ESRI is the dominant company in the geospatial data arena, with its ArcGIS mapping platform boasting with over a million users and 350,000 customers.

If the end of the coil that is hanging is grounded (earthed), it becomes an autotransformer. As it's shown, it's a variable inductor and the disconnected end is irrelevant and has no meaningful physical effect at the frequency a spark transmitter could have reached.

This comment seems to get closer to what they actually mean in their scientific paper. But the article about it is garble and the paper might suffer from second-language issues, and a lack of familiarity with the terms used in RF engineering.

NASA's Rocket Maker To Begin 3D Printing Flight-Ready Components 40

Lucas123 writes: United Launch Alliance (ULA), the company that makes rockets for NASA and the U.S. Air Force, plans to 3D print more than 100 flight-ready components for its next-gen Vulcan rocket. The company also just printed its first flight-ready component, a new Environmental Control System for its current Atlas V rocket. The ECS assembly had previously contained 140 parts that were made by third party suppliers, but ULA was able to reduce the parts to just 16, resulting in a 57% part-cost reduction. Along with cost reduction, ULA said 3D printing frees it from contracts with parts providers who may or may not deliver on time depending on whether the deem the rocket maker a priority at any given time. The company, which launches 12 rockets each year, is also hoping to use 3D printing for a more traditional role — rapid prototyping of parts. "We have a long list of [parts] candidates to evaluate — over 100 polymer parts we're considering and another 50 or so metal parts we're considering," said Greg Arend, program manager for additive manufacturing at ULA.

Why the Journey To IPv6 Is Still the Road Less Traveled 390

alphadogg writes The writing's on the wall about the short supply of IPv4 addresses, and IPv6 has been around since 1999. Then why does the new protocol still make up just a fraction of the Internet? Though IPv6 is finished technology that works, rolling it out may be either a simple process or a complicated and risky one, depending on what role you play on the Internet. And the rewards for doing so aren't always obvious. For one thing, making your site or service available via IPv6 only helps the relatively small number of users who are already set up with the protocol, creating a nagging chicken-and-egg problem.

Damn, I wish I would have patented that and all its quantum magic...

I noticed that my vertical transmitting antenna often works better if I connect a horizontal wire about the same length as the antenna to ground at its base! The wire isn't connected to the transmitting side of the circuit at all! And how well it works varies depending on the length! Obviously there is some deus ex machina at work here...

Clearly you missed the bit where they invoked quantum mechanics, surely that explains away all the inaccuracies, like the fact you can already buy chip scale dielectric antennas

The thing that I really hate about Innovation Stories is that the reporter invariably doesn't understand what's going on, and invariably is easily convinced that The Obviiously Very Technical People have some very valuable invention.

Colors Help Set Body's Internal Clock 52

First time accepted submitter MakeItGlow writes A new study by researchers from the University of Manchester found that mice use the color of light to set their body clock. The researchers investigated whether color signals from the eyes wound up in the suprachiasmatic nucleus—the part of the brain in vertebrates that keeps time using electrical and chemical signals. From the article: "Scientists have long known about the role light plays in governing circadian rhythms, which synchronize life’s ebb and flow with the 24-hour day. But they weren’t sure how different properties of light, such as color and brightness, contributed to winding up that clock. 'As a sort of common sense notion people have assumed that the clock somehow measures the amount of light in the outside world,' says Tim Brown, a neuroscientist at the University of Manchester in the United Kingdom and an author of the new study. 'Our idea was that it might be doing something more sophisticated than that.'”

Submission + - Security Companies Peddling Snake Oil - Buyer Beware Says Paul Vixie

penciling_in writes: There are no silver bullets in Internet security, warns Paul Vixie in a co-authored piece along with Cyber Security Specialist, Frode Hmmedal: "Just as 'data' is being sold as 'intelligence', a lot of security technologies are being sold as 'security solutions' rather than what they for the most part are, namely very narrow focused appliances that, as a best case, can be part of your broader security effort." We have to stop playing "cops and robbers" and pretending that all of us are potential targets of nation-states, or pretending that any of our security vendors are like NORAD, warn the authors.
