A Reprogrammable Space Probe Design For Mission Multitasking in Orbit

The Juno Space Probe: Honest to blog courtesy of NASA

From Popsci.com:

Multi-purpose hardware lets Japanese satellite change its mission on the fly.

Right now, thousands of satellites are circling the Earth. They're a diverse bunch. Some relay telephone calls, some spy on North Korea, some monitor the weather. But they all have one thing in common: each can only do one thing. A spy satellite can't suddenly start forecasting storms, and a communications satellite can't study asteroids.

Well, that's all about to change.

Researchers at the Institute of Space Systems at the University of Stuttgart, Germany, have designed a variable-function satellite that can alter its mission on the fly.

Evolutionary Origins of Your Right and Left Brain

In the human brain the left hemisphere controls language, the dexterity of the right hand, the ability to classify, and routine behavior in general. The right hemisphere specializes in reacting to emergencies, organizing items spatially, recognizing faces and processing emotions.

From Scientific American:

The division of labor by the two cerebral hemispheres—once thought to be uniquely human—predates us by half a billion years. Speech, right-handedness, facial recognition and the processing of spatial relations can be traced to brain asymmetries in early vertebrates

The left hemisphere of the human brain controls language, arguably our greatest mental attribute. It also controls the remarkable dexterity of the human right hand. The right hemisphere is dominant in the control of, among other things, our sense of how objects interrelate in space. Forty years ago the broad scientific consensus held that, in addition to language, right-handedness and the specialization of just one side of the brain for processing spatial relations occur in humans alone. Other animals, it was thought, have no hemispheric specializations of any kind.

HONG KONG (Reuters) - Dust clouds generated by a huge dust storm in China's Taklimakan desert in 2007 made more than one full circle around the globe in just 13 days, a Japanese study using a NASA satellite has found.

When the cloud reached the Pacific Ocean the second time, it descended and deposited some of its dust into the sea, showing how a natural phenomenon can impact the environment far away.

"Asian dust is usually deposited near the Yellow Sea, around the Japan area, while Sahara dust ends up around the Atlantic Ocean and coast of Africa," said Itsushi Uno of Kyushu University's Research Institute for Applied Mechanics.

Five Human Achievements That Could Top Walking on the Moon

Free Fusion Energy?: The National Ignition Facility Target Room

From Popsci.com:

Forty years after Apollo 11, a look forward at the world-changing discoveries that could match--or even top--humankind's first steps on the moon.

Possibly the single most influential event in the public's interest in science and technology (not to mention one of humankind’s greatest adventures), the Apollo 11 mission touched the collective dreams of millions, while pushing science and technology swiftly forward at an unprecedented pace.

But in the decades since man first walked on the moon, science has advanced so rapidly that technology which even a few years ago might have been considered magic has become commonplace. Even so, it would be naïve to assume that Apollo 11 ever represented science and technology’s pinnacle, and that nothing forthcoming will similarly explode the world’s collective dreams and perceptions of what it means to be human.

From ABC News:

For Some, Going to the Moon Became a Spiritual, Philosophical Event.

In the history of humanity, only 24 men have shared the experience.

Forty years ago today, the first of the two dozen astronauts to fly to or around the moon rocketed away from Earth to make history. Twelve had the chance to walk on the moon's surface, though only nine of those are still alive today.

When they returned to Earth, they were scientists and explorers with no peers, at the pinnacles of their careers.

But for some the adventure was so epic it changed the course of their lives. Inspired and transformed by seeing Earth shrink to the size of their thumbs, many let new philosophical and spiritual sensibilities guide them. Others chose entirely new career paths.

Apollo 11 reached the moon's surface 40 years ago today with Neil Armstrong and his fellow astronauts Buzz Aldrin and Michael Collins on board. Here are some key quotes from the mission that put the first men on the moon.

"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth." President John F. Kennedy announces his intention to put a man on the Moon before a joint session of Congress on May 25 1961

"No nation which expects to be the leader of other nations can expect to stay behind in this race for space...We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard." John F. Kennedy explains his lunar ambitions in a speech at Rice University on September 12, 1962

The world is on the verge of new manned exploration of the solar system – and, this time, environmentalists are backing it.

This weekend, 40 years after man first landed on the Moon, more human beings than ever before are orbiting on a single spacecraft. In 1969, three men squeezed into Apollo 11's command module, a craft little bigger than a Mini.

Yesterday, the International Space Station, now as large as a four-storey house, yet speeding at 17,239mph, took on board the crew of the shuttle Endeavour: 12 men, one woman – seven Americans, two Russians, two Canadians, one Japanese and a Belgian. During a two-man space-walk, the crew added a four-ton porch – an outdoor shelf for experiments – to the station.

From Yahoo News/AP:

WASHINGTON – The measure of what humanity can accomplish is a size 9 1/2 bootprint. It belongs to Neil Armstrong, the first man on the moon. It will stay on the moon for millions of years with nothing to wipe it away, serving as an almost eternal testament to a can-do mankind.

Apollo 11 is the glimmering success that failures of society are contrasted against: "If we can send a man to the moon, why can't we ..."

What put man on the moon 40 years ago was an audacious and public effort that the world hasn't seen before or since. It required rocketry that hadn't been built, or even designed, in 1961 when President John F. Kennedy declared the challenge. It needed an advance in computerization that had not happened yet. NASA would have to learn how to dock separate spaceships, how to teach astronauts to walk in space, even how to keep them alive in space — all tasks so difficult experts weren't sure they were possible.

From remote observatories on the Tibetan plateau to a cave in a Shanghai suburb, Chinese researchers are poised to conduct an audacious once-in-a-century experiment. The plan is to test a controversial theory: the possibility that gravity drops slightly during a total eclipse.

Geophysicists from the Chinese Academy of Sciences are preparing an unprecedented array of highly sensitive instruments at six sites across the country to take gravity readings during the total eclipse due to pass over southern China on 22 July. The results, which will be analysed in the coming months, could confirm once and for all that anomalous fluctuations observed during past eclipses are real.

Alaska's North Slope. Ccourtesy North Slope Borough

From Time Magazine:

A group of hunters aboard a small boat out of the tiny Alaska village of Wainwright were the first to spot what would eventually be called "the blob." It was a dark, floating mass stretching for miles through the Chukchi Sea, a frigid and relatively shallow expanse of Arctic Ocean water between Alaska's northwest coast and the Russian Far East. The goo was fibrous, hairy. When it touched floating ice, it looked almost black.

But what was it? An oil slick? Some sort of immense, amorphous organism adrift in some of the planet's most remote waters? Maybe a worrisome sign of global climate change? Or, as folks wondered who followed from faraway via the internet, was it something insidious and, perhaps, even carnivorous like the man-eating jello from the old Steve McQueen movie that inspired the Alaska phenomenon's nickname?

The young scientists who created the Saturn V rocket that powered Aldrin and Armstrong to the moon on Apollo 11 in July 1969 were the unsung heroes in the space race with the Soviet Union.

It wasn't a young president's brash promise that enabled Neil Armstrong and Buzz Aldrin to take those first halting steps on the lunar surface 40 years ago Monday. Nor was it the courage of the astronauts themselves.

The success of America's big bet in space depended on the ability of young, unheralded engineers to build rocket engines that were both powerful enough and reliable enough to wrench the spacecraft from Earth's jealous grasp and send it winging to the lunar surface.

From Live Science:

Biologists have found microbes that live in the hottest, coldest, driest and most unpleasant places on Earth. Many of these bugs don't adapt well to new surroundings, but one microbe is remarkable for withstanding a wide range of conditions. This quality might make this unique organism suitable for adapting to life on Mars.

This ultimate survivor is called Methanosarcina barkeri. It is found in freshwater and marine sediments, and other places where oxygen is scarce. Because it breathes out methane, researchers are interested to see if it — or some other "methanogen" — could be responsible for the methane that was detected in the martian atmosphere in 2003.

Expiration Dates

From Organize Your Life:

Certain items in your house practically scream “toss me” when their prime has passed. That mysterious extra white layer on the Cheddar? A sure sign it needs to be put out of its misery. Chunky milk? Down the drain it goes.

But what about that jar of olives or Maraschino cherries that has resided in your refrigerator since before the birth of your kindergartner?

With help from experts and product manufacturers, Real Simple (http://www.realsimple.com/) has compiled a guide to expiration dates. These dates are offered as a rough guideline. The shelf lives of most products depend upon how you treat them. Edibles, unless otherwise indicated, should be stored in a cool, dry place. (With any food, of course, use common sense.) Household cleaners also do best in a dry place with a stable temperature. After the dates shown, beauty and cleaning products are probably still safe but may be less effective.

10 Stunning (And Useful) Stats About Twitter

From Information Marketing Blog:

Last month a social media analytics provider named Sysomos released a comprehensive report on Twitter usage. The problem with most analysis on Twitter, though, is that it is limited by the minimal amount of data that Twitter collects. So, to fill the gaps, most reports do things like guessing gender based on real names or pulling data from keywords in people's biographic information.

Shepherd's delight: A particularly fiery red sky over fields in Leicestershire last night after an eruption at Sarychev Peak in Russia unleashed a colourful mixture of ash and sulphur. When this 'volcanic aerosol' in the stratosphere mixes with the red light of the setting sun, it produces a vivid crimson hue

From The Daily Mail:

The night skies over Britain will turn a deep shade of crimson this week as the fallout from a Russian volcano blast hits the UK.

Millions of tonnes of dust, ash and sulphur dioxide were thrown up to 30 miles into the air when Sarychev Peak on Matua Island in the Kuril Archipelago erupted last month.

The blast created what experts call a ‘volcanic aerosol’ - a colourful mixture of ash and sulphur compounds - in the stratosphere.

This scatters an invisible blue glow which, when mixed with the red light of the setting sun, produces a ‘volcanic lavender’, or vivid crimson/violet hue.

I would feel relaxed and at peace yet excited and joyful, and I occasionally experienced a thrill so powerful that it sent shivers down my spine. I also felt connected with fellow musicians in a way I did not with friends who did not sing with me.

India Moon Probe 'Malfunctions'

From The BBC:

India's first mission to the Moon has experienced a technical problem, India's space research officials say.

A sensor of the unmanned Chandrayaan-1 spacecraft has "malfunctioned" and steps have been taken to ensure it is able to continue its work, they say.

But the possibility remains that the mission may have to be cut short.

Chandrayaan-1 was launched last October and is regarded as a major step for India as it seeks to keep pace with other space-faring nations in Asia.

Man And Machine The Real Legacy Of The Moon Race

From Boston.com:

For the millions who watched the grainy television feed from the moon on July 20, 1969, Neil Armstrong’s small step seemed to herald a new era. Arthur C. Clarke had already predicted that the children born during the Apollo missions would one day have their passports stamped on the moon; in the lunar spectacle, we glimpsed a brighter future in which humans would conquer the vastness of space and acknowledge their brotherhood on the pale blue dot of the home planet.

And yet, 40 years on, the Apollo program looks less like the start of a new era and more like an ancient culture that flourished briefly and then vanished, leaving only ruined towers, ritual costumes, and incomprehensible glyphs. In the decades since the last towering Saturn V tore through the night sky, NASA’s astronauts have spent their time on modest missions closer to home. The age of easy space travel that Apollo seemed to promise never materialized. And for all its technological marvels, Apollo bequeathed little to our material culture besides instant orange drink, freeze-dried ice cream, and the statuettes of the MTV video music awards.

Inside the New Harry Potter Movie's VFX Tech

From Popular Mechanics:

The sixth Harry Potter movie, Harry Potter and the Half Blood Prince, opens today. Recently, PM's Digital Hollywood spoke with the film's visual-effects supervisor, Tim Burke, and with Tim Alexander of Industrial Light & Magic, about some of the technical effects behind the new wizarding film.

Millennium Bridge
At the beginning of Harry Potter and the Half-Blood Prince—the first Potter film in two years, out today—things are looking pretty grim not just for the boy wizard, but for everyone. Gray storm clouds roll ominously over London as pedestrians, eyes on the sky, hurry across the city's Millennium Bridge. Suddenly, the bridge begins to quake. Cables snapping, the bridge undulates and twists, pulling free of its piers, and crashes violently into the Thames. Voldemort has recently returned from the dead, and he isn't satisfied to wreak havoc only in the wizarding world: His Death Eaters take his campaign of violent mayhem into the Muggle realm by destroying the Millennium Bridge in the film's dramatic opening sequence.

From CNET News:

Forty years after the Apollo 11 voyage to the moon, NASA released photographs from the new Lunar Reconnaissance Orbiter spacecraft Friday showing five of the six Apollo landing sites. Shadows cast by the Apollo descent stages are clearly visible and in some cases, the moon walkers' paths can be seen in the disturbed dust.

"We were very interested in getting our first peek at the lunar module descent stages just for the thrill - and to see how well the cameras had come into focus," Mark Robinson, principal investigator of the LRO's main camera, said in a statement. "Indeed, the images are fantastic and so is the focus."

From Popsci.com:

A team at Harvard decided to reinvestigate the potential for windpower around the globe, and found their new results to be significantly different than previous studies. According to the new study, we're capable of someday producing 40 times more power via wind than we currently consume overall.

This finding corresponds with recent research suggesting that you can draw more power at higher altitudes. The Harvard study is based around the use of taller 100-meter turbines, as opposed to 50-to-80-meter turbines.

Terror As Hundreds Of 5ft Long Creatures Of The Deep Invade Californian Coastline -- The Daily Mail

Hundreds of aggressive jumbo flying squid have appeared off the coast of San Diego, attacking divers and washing up dead on beaches.

The 5-foot long sea monsters, which have razor-sharp beaks and toothy tentacles, have been bringing terror to scuba drivers and swimmers on the coast's tourist-packed beaches.

The carnivorous calamari, which can grow up to 100 pounds, came up from the depths last week and swarms of them have pounced on unsuspecting divers.
