Atlantis Mission Threatened By "Russian Debris"

Mission control is monitoring space junk to make sure it doesn't get too close during a space walk

'Russian' Debris Threatens Atlantis Mission As Ground Control Fears It Will Hurtle 'Dangerously Close' To ISS During Space Walk -- Daily Mail

* Nasa is trying to work out if the junk comes from a defunct Russian satellite
* It is scheduled to pass the space station at around 5pm GMT on Tuesday

Nasa is monitoring a piece of 'Russian' space junk that looks likely to come dangerously close to the International Space Station during a planned space walk tomorrow.

The debris is heading towards the station, where Atlantis yesterday docked on its final mission.

Scientists are still trying to work out how big the object is and how close it will come to Atlantis. Some believe it originated from a defunct Russian satellite that is orbiting Earth.

Why Cyberwar Is Unlikely -- Live Science

In this last of a three-part series, LiveScience's sister site SecurityNewsDaily explores truths, distortions, confusions and likelihood of cyberwar. Click for Part 1: Cyberwar: Definition, Hype and Reality and Part 2: What Cyberwar Would Look Like.

Even as more and more countries invest in the idea of cyberwarfare, cyberspace remains largely peaceful insofar as actual war is concerned.

In the two decades since cyberwar first became possible, there hasn't been a single event that politicians, generals and security experts agree on as having passed the threshold for strategic cyberwar.

Ten Tech Innovations From NASA's Space Shuttle That Trickled Down to Non-Astronauts -- Popular Science

Tech designed for the space shuttle program have permeated just about every aspect of our lives. Here are ten you may not know about.

Your life is full of what NASA calls "spinoffs": ideas or products initially designed for NASA's particular (and particularly challenging) uses, but which trickled down to become commercial products. Of course, you may not recognize these items--there's no "made for NASA" sticker, and many of the iconic NASA products (Tang, Teflon, Velcro) weren't actually designed for or by NASA at all. But NASA-developed stuff is everywhere, from insulation to infant formula, from prostheses to fishing nets. Here are ten of our favorites that originated in the Shuttle program--the very program that just saw its last launch ever.

NASA Tracking Space Debris In Space Station's Path

This handout illustration image created by Australia's Electro Optic Systems (EOS) aerospace company shows a view of the Earth with low-orbiting space debris. The US space agency is tracking a piece of space junk that could be on a path toward the International Space Station, where the shuttle Atlantis has just docked on its final mission, NASA said.

From Yahoo News/AFP:

The US space agency is tracking a piece of space junk that could be on a path toward the International Space Station, where the shuttle Atlantis has just docked on its final mission, NASA said Sunday.

However, NASA is not ready to say for sure whether the object is projected to collide with the shuttle and station, though the paths were likely to cross on Tuesday, said deputy manager of the space shuttle program LeRoy Cain.

"What we were told today is very preliminary," Cain said. "It is a potential right now."

Better Eyes For The Next Generation of UAVs



Hyperspectral Sensors: The Flying Eyes That See The Invisible -- Popular Mechanics

Hyperspectral imagers seen in bands of light that humans cannot. They are changing the way satellites scan the world, and now they're about to go aboard unmanned aircraft.

Bees see what we don't. Their eyes are adept at seeing in ultraviolet, so much so that flowers have evolved colorful patterns visible only in UV to attract bees' attention.

The vision of these buzzing insects is just one example of what lies beyond the limits of our naked eyes. In the bands beyond what we can see, there's lots of data that can be used to identify objects. But a new breed of man-made sensors is, like the eye of a bee, plucking information from a wider part of the spectrum than a camera or eye can see.

A Separate Internet Could Curb Cyber Threats

The U.S. Navy Cyber Defense Operations Command The U.S. military and intelligence arms are already defending the nation from cyber attacks. DARPA hopes to give them another tool.

Former CIA Chief: A Separate Internet Could Curb Cyber Threats -- Popular Science

To combat cyber attacks, the U.S. may need more than new cyber defenses. It might need a whole new piece of Internet infrastructure. So says former CIA director Michael Hayden, who served under President G.W. Bush, and he’s not the only one. Several lawmakers and the current Cyber Command chief Gen. Keith Alexander are toying with the notion of creating a “.secure” domain where Fourth Amendment rights to privacy are voluntarily foregone in order to keep that corner of the Internet free of cyber criminals.

My Comment: We are going down this pathway, and while setting up the infrastructure for a separate but secure will be expensive .... the alternative of letting everything continue as is may end up being even more pricey.

Stardust in Our Backyard Provides New Clues to Galaxy Evolution -- Science Daily

ScienceDaily (July 7, 2011) — New data from the European Space Agency's Herschel Space Observatory have revealed surprisingly large amounts of cold dust in the remnant of the famous supernova SN1987A, which exploded 24 years ago in the Large Magellanic Cloud, a neighboring galaxy of the Milky Way. With this discovery, astronomers confirm that supernovae are able to produce significant quantities of dust over very short time scales. This may help explain previous observations, by Herschel and other observatories, of abundant dust in the early Universe as seen in high-redshift galaxies.

Los Alamos Nuclear Laboratory Remains Closed As Wildfires Threaten Facility



Los Alamos Fire: EPA Testing for Radiation -- ABC News

The wildfire that surrounds the nuclear lab in Los Alamos, New Mexico, has grown to at least 61,000 acres amid mounting concerns about what might be in the smoke that's visible from space.

Such fear has prompted the Environmental Protection Agency to bring in air monitors, along with a special airplane that checks for radiation levels. So far officials have not been able to find anything.

"Our facilities and nuclear material are protected and safe," Laboratory Director Dr. Charles McMillan told ABC News.

A Look At Cyberwarfare And Hackers From A Russian Perspective

Evgeny Kaspersky was trained as a cryptologist and went on to co-found Kapersky Labs, which makes antivirus, anti-spyware, anti-spam and other online security products. In a recent SPIEGEL interview, he discussed a number of what he sees as worrying trends in cyber security. Regarding the new era of cyber war, he stated: "This war can't be won; it only has perpetrators and victims. Out there, all we can do is prevent everything from spinning out of control. Only two things could solve this for good, and both of them are undesirable: to ban computers -- or people." Sergei Chirikov/ AFP/ Getty Images

Google Earth Goes Under the Sea



From Popular Science:

Google Earth broke new ground (new water?) when they took the world of virtual-earth-exploring into the oceans. Of course, the oceans are kind of big. They fill up nearly three-quarters of the earth's surface area, and most of that area hasn't been mapped out. But now you can tour roughly half of the known area without pulling on any SCUBA gear, thanks to Google's new underwater terrain explorer.

Commentary On Europe's Organic Food Scare



Europe's Organic Food Scare -- Wall Street Journal

German Greens and their European Union acolytes have long fought scientific advances in food production and protection. After a spice manufacturer in Stuttgart employed the world's first commercial food irradiation in 1957, West Germany banned the practice in 1959 and has since allowed few exceptions. So it's no small scandal that the latest fatal E. coli outbreak has been linked to an organic German farm that shuns modern farming techniques.

When The Sun Unleashed Its Plasma Blast This Week, Earth Got Lucky -- Popular Science

What a predicted 2013 blast from the sun could mean for the U.S.

On Tuesday, the biggest solar flare in four years erupted from the sun, sending a mass of charged particles hurtling towards Earth. NASA announced that it was an M-2 (medium-sized) flare and an S1-class (minor) radiation storm. The electromagnetic pulse it induced created amazing auroras, but it could also damage satellites and radio communications. What would happen with an even stronger, larger flare? Something terrible...

New 'Subatomic Particle' Likely A Fluke

The CDF detector, about the size of a three-story house, weighs about 6,000 tons. It recrods the "debris" emerging from each high-energy proton-antiproton collision produced by the Tevatron. CREDIT: Fermilab

From Live Science:

A report in April suggesting a giant atom smasher may have detected a never-seen-before subatomic particle had physicists at the edge of their seats with hope, albeit with a healthy dose of skepticism. Now an independent test of the results suggests it was just a fluke.

The tantalizing signal came from the Tevatron particle accelerator at the Fermilab physics laboratory in Batavia, Ill. Inside the accelerator there, particles race around a 4-mile (6.3 km) ring at near light speed. When two particles collide, they disintegrate into other exotic particles in a powerful outpouring of energy. [Wacky Physics: The Coolest Little Particles in Nature]

Most Apples Have Pesticide Residues

Apples Top List For Pesticide Contamination -- CBS News

That shiny little apple you're eating has a dirty little surprise. At least, that's what a food safety watchdog claims in its annual examination of government produce tests.

The Environmental Working Group says apples top its "Dirty Dozen" list of fruits and vegetables with the highest amounts of pesticides. "We found that nearly every apple sampled, 98 per cent, had pesticide residues," says Sonya Lunder, a senior analyst. "This is an accumulation of 48 different pesticides."
