Low Quality Alloy Cause of Shuttle Main Tank Issue 118

BJ_Covert_Action writes "NASA engineers have finally discovered the root cause of the cracks that have been found on space shuttle Discovery's main external tank. The main tank, one of the 'Super Lightweight Tank' models developed by Lockheed-Martin, employs an aluminum-lithium alloy developed by Lockheed-Martin specifically for this application. The new alloy is used in various structural stringers throughout the SLWT design. Unfortunately, the batch of this alloy used in the tank that is currently mated with the Discovery shuttle appears to be of low quality. The alloy used in the stringers has a 'mottled' appearance, compared to the nominal appearance typically used in the main tank stringers (see picture in article). This appearance is indicative of a fracture threshold that is significantly lower than typical. NASA has determined, through testing, that this low grade alloy has only 65% of the fracture strength of the nominal alloy typically used. NASA engineers have devised a potential fix to the problem that they are currently testing to ensure the repair will cause no unintended consequences. NASA plans to have the Discovery shuttle ready to launch again by February 24th, 2011."

NASA Says 2010 Tied For Warmest Year On Record 554

An anonymous reader writes "It may not seem like it, but 2010 has tied 2005 as the warmest year since people have been keeping records, according to data from NASA's Goddard Institute for Space Studies in New York. The two years differed by less than 0.018 degrees Fahrenheit. That difference is so small that it puts them in a statistical tie. In the new analysis, the next warmest years are 1998, 2002, 2003, 2006 and 2007, which are statistically tied for third warmest year. The GISS records begin in 1880." Adds jamie: "This was the 34th consecutive year with global temperatures above the 20th century average — 0.62 +/- 0.07 C above, to be precise. It was the wettest year on record too, according to the Global Historical Climatology Network."

Amazon EC2 Enables Cheap Brute-Force Attacks 212

snydeq writes "German white-hat hacker Thomas Roth claims he can crack WPA-PSK-protected networks in six minutes using Amazon EC2 compute power — an attack that would cost him $1.68. The key? Amazon's new cluster GPU instances. 'GPUs are (depending on the algorithm and the implementation) some hundred times faster compared to standard quad-core CPUs when it comes to brute forcing SHA-1 and MD,' Roth explained. GPU-assisted servers were previously available only in supercomputers and not to the public at large, according to Roth; that's changed with EC2. Among the questions Roth's research raises is, what role should Amazon and other public-cloud service providers play in preventing customers from using their services to commit crimes?"

Mozilla To Release Firefox 4 Next Month 266

Neil writes "Damon Sicore, Senior Director of Platform Engineering at Mozilla, has announced that the company is almost ready to ship Firefox 4. On its mailing list, Mozilla has revealed it has around 160 hard blockers to fix, before proceeding to Release Candidate stage. Both the RC and the final version would arrive in February, according to Sicore. Mozilla was originally planning on having Firefox 4 out by the end of last year, but it had to delay the release till 2011. Last month, Firefox 4 Beta 8 was released for Windows, Mac OS X, and Linux 32-bit/64-bit, with support for 57 languages. Mozilla's roadmap says it still wants to release a Beta 9, a Beta 10, and at least one Release Candidate build before the final version."

Florida Man Sues WikiLeaks For Scaring Him 340

Stoobalou writes "WikiLeaks founder Julian Assange has been accused of 'treason' by a Florida man seeking damages for distress caused by the site's revelations about the US government. From the article: 'David Pitchford, a Florida trailer park resident, names Assange and WikiLeaks as defendants in a personal injury suit filed with the Florida Southern District Court in Miami. In the complaint filed on 6th January, Pitchford alleges that Assange's negligence has caused "hypertension," "depression" and "living in fear of being stricken by another heart attack and/or stroke" as a result of living "in fear of being on the brink of another nuclear [sic] WAR."' Just for good measure, it also alleges that Assange and WikiLeaks are guilty of 'terorism [sic], espionage and treason.'"

Playmate Photo From Apollo 12 Up For Auction 211

Kilrah_il writes "When the Apollo 12 crew left Earth for a trip to the Moon, they did not know that the ground crew hid a surprise in one of the command module lockers: a calendar photo of Playboy Playmate DeDe Lind. Now this card is offered for auction, after being kept in the personal collection of command module pilot Richard Gordon, who added the following memo: 'This is to certify that the accompanying 4.5" x 6.25" cue card did, indeed, accompany me on my trip to the moon in the Command Module Yankee Clipper aboard the historic Apollo 12 lunar landing mission. This cue card, which flew with me to the moon, has been in my sole possession and part of my personal space collection since my return from the moon in 1969 aboard America's second lunar landing mission, and it remains one of the all-time greatest Apollo era astronaut "Gotcha's!"' For those interested, the minimum bid is $1000." Warning, contains pixelated nudity.

How Do You Visualize 100 GB of Google Text Data? 117

An anonymous reader writes "There is an amazing series of charts that visualizes trigrams and bigrams, portions of sentences that have been extracted from Google's web data set. The graphs highlight word associations and the frequency with which we use them on web pages. Chris Harrison from Carnegie Mellon University found, for example, that the word 'he' is often tied to 'argues,' while 'she' is found often with 'loves.' There are also word-relation charts that highlight words used in combination with their opposites, such as good and bad, peace and war, and PC and Mac." There are a lot of these things, and they're really interesting to browse through.

ISPs Warn Europe — Website Blocks Don't Work 210

Mark.JUK writes "The European Internet Services Providers Association has today warned the European Union that plans aimed at tackling online child sexual abuse content, which propose to force ISPs into adopting mandatory website blocking (censorship) technology, will not work because such methods are easy to circumvent; an ISP might cover your eyes but anybody can still take the blindfold off. Instead the EuroISPA has called for members of Parliament to consider permanently removing Internet-based child sexual abuse content at source, although this also runs into problems when the servers are based outside of your jurisdiction."

Hubble Confirms Nature of Mysterious Green Blob 140

An anonymous reader writes "In 2007, Dutch secondary school biology teacher Hanny van Arkel spotted something mysterious in the night sky. Combing through Galaxy Zoo, an online database set up to enlist the public's help in classifying galaxies, she came across a glowing green smudge of light approximately 650 million light-years away. The object, which became known as Hanny's Voorwerp (Dutch for 'object'), is one of the most mysterious in the universe. Now, detailed Hubble Space Telescope images and new x-ray observations presented here today at the 217th meeting of the American Astronomical Society may finally confirm what it is."

NASA's Kepler Spots Its First Rocky Exoplanet 97

coondoggie writes "NASA today said its star-gazing satellite Kepler has identified its first rocky planet orbiting a sun similar to our own — 560 light years from our solar system. While not in an area of space considered habitable, the rocky planet known as Kepler-10b is never-the-less significant because it showcases the ability of Kepler to find and track such small exoplanetary movements. 'Kepler's ultra-precise photometer measures the tiny decrease in a star's brightness that occurs when a planet crosses in front of it. The size of the planet can be derived from these periodic dips in brightness. The distance between the planet and the star is calculated by measuring the time between successive dips as the planet orbits the star. Kepler is the first NASA mission capable of finding Earth-size planets in or near the habitable zone, the region in a planetary system where liquid water can exist on the planet's surface. However, since it orbits once every 0.84 days, Kepler-10b is more than 20 times closer to its star than Mercury is to our sun and not in the habitable zone.'"

Hospital Wireless Networks May Be Regulated Medical Devices 185

Lucas123 writes "As hospitals continue to connect patient monitoring equipment, physician PDAs and laptops to wireless networks, and then collapse those data paths onto traditional IT networks, the closer the US Food and Drug Administration comes to regulating them, according to Computerworld. The focus of the FDA's regulation comes in its recently finalized 80001-1 standard that established risk management practices for those networks, the adherence to which may be voluntary, but would determine Medicaid and Medicare reimbursements. 'If you don't comply, then you have two choices. You can have the federal government come in and inspect your hospital, or you can decide not to accept money from Medicare or Medicaid. Voluntary sometimes isn't exactly voluntary,' said Rick Hampton, wireless communications manager for Partners HealthCare System in Boston."

Browser Exploit Kits Using Built-In Java Feature 96

tsu doh nimh writes "Security experts from several different organizations are tracking an increase in Windows malware compromises via Java, although not from a vulnerability in Windows itself: the threat comes from a feature of Java that prompts the user to download and run a Java applet. Kaspersky said it saw a huge uptick in PCs compromised by Java exploits in December, but that the biggest change was the use of this Java feature for social engineering. Brian Krebs writes about this trend, and looks at two new exploit packs that are powered mainly by Java flaws, including one pack that advertises this feature as an exploit that works on all Java versions."

Thieves in South Africa Hit Traffic Lights For SIM Cards 181

arisvega writes "Some 400 high-tech South African traffic lights are out of action after thieves in Johannesburg stole the mobile phone SIM cards they contain. JRA (Johannesburg Road Agency) said it is investigating the possibility of an 'inside job' after only the SIM card-fitted traffic lights were targeted. The cards were fitted to notify JRA when the traffic lights were faulty. 'We have 2,000 major intersections in Johannesburg and only 600 of those were fitted with the cards,' the agency's spokesperson Thulani Makhubela told the BBC. 'No-one apart from JRA and our supplier knows which intersections have that system.' The thieves ran up bills amounting to thousands of dollars by using the stolen cards to make calls."
