Two Telescopes Linked To Find Planets
glinden writes: "Two telescopes at the Kech Observatory have been optically linked to form the Keck Interferometer. The resolving power of this combined telescope will apparently be sufficient to see earth-sized planets around nearby stars." quoll contributes a link to NASA's own version of the story, too. -

Tux in Space
Anonymous Coward writes "In between all the bad news about Linux it's nice to see some good like this story about Linux getting used by NASA for satellite control I saw on NewsForge. It is on Linux Today too. This is not some garage dream but a real NASA project run by a real rocket scientist. Does ThinkGeek sell 'Tux in Space' T shirts yet? I want one!" NASA has a page for FlightLinux. -
Green Cheese? No.
deran9ed writes "The Department of Energy's Los Alamos National Laboratory present their latest findings from NASA's Lunar Prospector mission at the Lunar and Planetary Science Conference in Houston, Texas. The Los Alamos studies include data on Moonquake activity, further confirmation of the presence of water-ice on the moon, and mapping of iron and titanium using gamma-rays emitted when cosmic rays slam into the lunar surface. Here's the story on spacer.com." -
"Smart Probe" Detects Breast Cancer
xpccx writes: "I've seen in several scientific journals articles about a device called a 'Smart Probe.' It's a device from BioLuminate which is licensing technologies from NASA and the Lawrence Livermore National Laboratory. (Read more.)From the press release:
Sensors on the tip of the probe measure optical, electrical and chemical properties that are known to differ between healthy and cancerous tissues. The "Smart Probe" can detect multiple (5 to 7) known indicators of breast cancer. Tissue measurements are made in real time in both normal and suspect tissue.
I did a Google search and information can be found here(1), here(2) and here(3) amongst others.It's still an invasive procedure, but if it does work it would be a great relief to women who would normally go through unecessary biopsies. "In the U.S. each week, approximately 16,000 women undergo unnecessary, surgical breast biopsies on suspicious tissue that turns out benign.""

Eros A Relic Of Solar System's Dawn, Says NASA
Kumba writes: "Found this news story while browsing NASA's webpage. Before the NEAR Satellite arrived at Eros, scientists wondered what Eros was, be it a piece of a planet that broke up billions of years ago or a jumble of boulders held together by weak gravity. Now NASA believes Eros to be one of the building blocks of our solar system, what astronomers call planetesimals. It's a very interesting article to read, briefly explaining how our solar system came to be through the formation of these planetesimals and proto planets, and other such neat stuff." -
Giant Neutrino Detector, 2km Underground
yulek writes: "Yesterday's APOD ran an incredible photograph from the recently completed SNO Detector, a giant geodesic neutrino detector buried 2km (!) underground near Kingston Ontario. Neutrinos are some of the most bizarre subatomic particles, having virtually no mass and able to 'pass through matter like smoke.' The SNO Detecter is definitely one of the coolest and most ambitious experiments i've seen in recent years." -

Life On Mars: ALH84001
Celestius writes "This press release from NASA Ames states that 'An international team of researchers has discovered compelling evidence that the magnetite crystals in the martian meteorite ALH84001 are of biological origin,' and moreover that these crystals are not only older than any previously known form of life, but were also definitely formed before the meteor fell to Earth. Skeptics remain, of course, as quoted in this article from today's Chronicle, but suffice to say, NASA seems pretty confident." There's also a report on the BBC as well. -
Quickies Knows Quickies. Quickies is Quickies.
We'll start this off with Ant's submission -- a hilarious story about The Endor Holocaust which no doubt follows the destruction of the 2nd Death Star. After reading something so clear, confuse your mind confuse your mind (thanks to The Musician). Now that you are adequately confused, cardoso sent us a ridiculous flash app where you can control dancers. This will put you in the mood to enjoy the most retro homepage ever, sent in by mvw Got some money to burn? Check out the Spinal Tap Guitar which features among other things, chrome exhaust pipes and a tachometer that (of course) goes to 11. If you're not a musician, maybe you'd be interested in Randy Rathbun's link to personalized action figures: I could send in my mugshot and be immortalized in plastic, standing forever atop my monitors with Darth, Goku, and Trinity! Or maybe you wanna buy a Dalek? If you're on more of a budget, Jay Novak sent us a great t-shirt from copyleft considering all the layoffs around the net companies. With all of these great things to waste cash on, you might need some cash: geekguy sent in a funny list of ways to cash in on Doom without wasting time making a game (like for example, Doom breakfast serial! Free BFG inside!) Just get id to license ya! For you do-it-yourselfers, mr100percent submitted what might be the most impressive automotive MP3 player ever. The Pathintosh is a beautifully integrated Mac complete w/ steering wheel controls, and a custom bezel. And finally, the eycandy. First up is davco9200's link to Daily Astronomy Astropix which is actually pretty sweet: today is Mars Dunes. Second and last of all, the pr0n: Jeff K sent in Unix-Sex which features sysadmins getting it on w/ Sun Hardware. Thats why we don't let them work 3rd shift. -
NASA Launches Largest Single-Cell Balloon
hohosforbreakfast writes "According to CNN, NASA launched the largest single-cell, fully-sealed balloon ever from Australia. This thing is supposed to be as large as a football (American) stadium once it's fully inflated, and flies 20 miles high. It'll circumnavigate the globe and then be landed by remote control in Australia. It looks like this flight is a proof-of-concept, but more flights, lasting 100 days each, are planned. Looks like an interesting alternative to satellites for certain observations. The official site is here." -
Is Space Junk Still A Problem?
critic666 asks: "I've been doing some research on space junk (trash orbiting the Earth), but most of the discussion about it seems to come from 1996 - 98. The only recent thing I've seen about space junk is from an Aug 20, 2000 article on NASA creating a laser "broom" to cleanup this trash. Does anyone know if anything's really being done about space junk now, is it just kind of a static issue, or have we solved the problem?" Most of Earth's "artificial satellites", as I like to call them, have orbits that will eventually destabilize, so that they'll eventually burn up on re-entry, however, this doesn't mean that there isn't still quite a lot of junk up there. NASA maintains a database of most of the larger pieces and does track them via radar and the Johnson Space Center maintains their own page on the subject. You might want to check out the FAQ. Thoughts? -

Fox Moon Special Response
An anonymous reeader writes "The other day the Fox Network showed an ill-researched program about how the moon landings were hoaxed. Nasa has responded on their front page, here. Since the community here appreciates science, here is a page originally linked to on the NASA site about refuting the illogical arguments of non-believers: badastronomy.com." -
'From Ellipses to Gravity Assists' Webcast Presentation
Bottomquark writes "Tonight NASA scientist Charley Kohlhase, who has led trip-planning efforts for NASA missions to most of the planets in the solar system, will give a live webcast presentation called 'From Ellipses to Gravity Assists'. He'll explain how to choose the best routes for getting to destinations such as Mercury, Mars and Saturn, and describe how spacecraft can use the gravity of one planet to gain a "slingshot" boost toward a more distant destination. The 90 minute presentation takes place February 13, 2001 4:30-6:00 PM (PST) (24:30 GMT - 02:00 GMT), and will be broacast through LiveOntheNet.com (free registration required)." -
NEAR Touches Down on Eros
Every once in a while NASA does something amazing. Today they took a probe that was just supposed to orbit a rock the size of Manhattan, guided it down to the surface, reoriented the dish, and sent back a hello from ground zero. The NEAR Shoemaker mission site and its mirror are a little busy at the moment, but CNN's coverage is good, with simulated video, and actual photos from two hundred million miles up. Some engineers, and the operators at Johns Hopkins, must be awfully proud right about now. -

Mars Global Surveyor Recap
ScottMaxwell writes: "Though the date passed with little notice, JPL's Mars Global Surveyor spacecraft recently completed its primary mission, to study Mars for a full Martian year (about 687 Earth days). It's returned more mission data than all previous Mars missions combined, including some of the best evidence yet that water once flowed freely on the Martian surface. Check out the project's Web site for more info and images (including my personal favorite) as MGS moves into its extended mission." -

Open-Source Processors
clay pigeon writes "This EE Times article covers the development of open-source processors. No doubt exciting news for hardware hackers and those with a need to know about every last detail of their systems, but how will this effect the hardware industry? Can open-source hardware duplicate the success of the open-source software movement?" I'm not holding my breath. Fabrication facilities are a lot more expensive then a CD-ROM presses (or more accurately, internet connections). But I still hope it happens. It would be an interesting market if everyone worked together on the designs, but built their own chips. -
NASA Controls Jet With Nerve Signals
__roo writes: "According to this press release, NASA scientists were able to control a 757 jumbo jet simulation using neurolectric machine control -- muscle-nerve signals fed to a computer, which used a neural net to learn how to interpret the signals. The first prototype armband was made from exercise tights, and used metallic dress-buttons as dry electrodes. This page has high resolution photos of the device." -

Eastern US Cooling Despite Global Warming
[Tex] writes "While the rest of the world swelters, i'll be nice and cool...this article from NASA describes a general cooling trend over the Eastern US due to global warming. Warmer waters in the Pacific have created increased cloud cover on this side of the states, resulting in lower temperatures. Jeff Goldblum could probably explain this better... :)" -

Designing A Linux Distribution For NASA?
Zenker asks: "At NASA we are offering Linux as an alternative to Windows for anyone who wants it. I am working on a contract that puts a new computer on everyone's desktop and we will provide support and services for them. I need to assemble a distribution that will have all the necessary applications without flooding them with numerous option. I don't want to support every word processor and every spreadsheet out there. A good security policy is also necessary. What distribution would you use as a base for supporting a few hundred Linux desktops? Which applications would be standard for your office suite? What would your security policy be?" -

The Sounds Of Space Near Jupiter
Kumba writes "Found this while perusing NASA's Web site. It's an audio clip produced from radio waves detected near Jupiter by NASA's Cassini spacecraft, and converted to audible sound by some scientists at the University of Iowa. A clip that they had last week was described by the Los Angeles Times as sounding "like a troop of howler monkeys battling underwater." The new audio clip is....difficult to describe in my opinion. I guess it's best left to each listener to determine what it sounds like, but if you've ever wondered what it sounds like out there, this is it." I had a set of five CDs a while back that had collections of sounds made from one of the NASA missions - it was called Sounds of Space or the Universe. Pretty interesting set - but then, of course, like most of my possessions it burned in a house fire and I've been unable to find it since then. -

Blackjack: Ultra-Accurate GPS Measurement
Conrad_Bombora writes: "NASA's Blackjack Global Positioning System (GPS) receiver, flying on the Argentine satellite SAC-C provides a new way to study Earth's gravity field and atmosphere. The Blackjack looks at how the radio signals from the constellation of GPS satellites are distorted or delayed along their way. While a typical GPS receiver can determine its position to about 22 yards, the BlackJack can pinpoint the position of its host satellite continuously an accuracy of about one inch, and can be used for a variety of Earth studies." The paragraph I find most interesting says "the BlackJacks are also equipped with small down-looking antennas to attempt to receive GPS signals that reflect off the oceans." -
Using Distributed Wetware To Analyze Mars Craters
A non-mouse Cow Herd writes: "Here's an interesting NASA project that popped up on sci.space.sience a while back: This site allows volunteers to classify craters on mars, essentially a human distributed image processing program. They are even starting a moderation-like quality rating. So what do you think ? Would you devote your spare cycles to this ? Will the get quality work or just a lot of First Posts ?" Seems almost (but not quite) paradoxical to use an ultra-high-tech infrastructure to organize non-automated piecework, but until there's a sand mouse for crater-recognition, it seems like a really smart idea. -
