Seattle Company Raises Minimum Wage to $70,000 a Year For All Employees!






Excerpt from nytimes.com

The idea began percolating, said Dan Price, the founder of Gravity Payments, after he read an article on happiness. It showed that, for people who earn less than about $70,000, extra money makes a big difference in their lives.

His idea bubbled into reality on Monday afternoon, when Mr. Price surprised his 120-person staff by announcing that he planned over the next three years to raise the salary of even the lowest-paid clerk, customer service representative and salesman to a minimum of $70,000.

“Is anyone else freaking out right now?” Mr. Price asked after the clapping and whooping died down into a few moments of stunned silence. “I’m kind of freaking out.”

If it’s a publicity stunt, it’s a costly one. Mr. Price, who started the Seattle-based credit-card payment processing firm in 2004 at the age of 19, said he would pay for the wage increases by cutting his own salary from nearly $1 million to $70,000 and using 75 to 80 percent of the company’s anticipated $2.2 million in profit this year.

The paychecks of about 70 employees will grow, with 30 ultimately doubling their salaries, according to Ryan Pirkle, a company spokesman. The average salary at Gravity is $48,000 year.

Mr. Price’s small, privately owned company is by no means a bellwether, but his unusual proposal does speak to an economic issue that has captured national attention: The disparity between the soaring pay of chief executives and that of their employees.

The United States has one of the world’s largest pay gaps, with chief executives earning nearly 300 times what the average worker makes, according to some economists’ estimates. That is much higher than the 20-to-1 ratio recommended by Gilded Age magnates like J. Pierpont Morgan and the 20th century management visionary Peter Drucker.

“The market rate for me as a C.E.O. compared to a regular person is ridiculous, it’s absurd,” said Mr. Price, who said his main extravagances were snowboarding and picking up the bar bill. He drives a 12-year-old Audi, which he received in a barter for service from the local dealer.

“As much as I’m a capitalist, there is nothing in the market that is making me do it,” he said, referring to paying wages that make it possible for his employees to go after the American dream, buy a house and pay for their children’s education.

Under a financial overhaul passed by Congress in 2010, the Securities and Exchange Commission was supposed to require all publicly held companies to disclose the ratio of C.E.O. pay to the median pay of all other employees, but it has so far failed to put it in effect. Corporate executives have vigorously opposed the idea, complaining it would be cumbersome and costly to implement.

Mr. Price started the company, which processed $6.5 billion in transactions for more than 12,000 businesses last year, in his dorm room at Seattle Pacific University with seed money from his older brother. The idea struck him a few years earlier when he was playing in a rock band at a local coffee shop. The owner started having trouble with the company that was processing credit card payments and felt ground down by the large fees charged.

When Mr. Price looked into it for her, he realized he could do it more cheaply and efficiently with better customer service.

The entrepreneurial spirit was omnipresent where he grew up in rural southwestern Idaho, where his family lived 30 miles from the closest grocery store and he was home-schooled until the age of 12. When one of Mr. Price’s four brothers started a make-your-own baseball card business, 9-year-old Dan went on a local radio station to make a pitch: “Hi. I’m Dan Price. I’d like to tell you about my brother’s business, Personality Plus.”

His father, Ron Price, is a consultant and motivational speaker who has written his own book on business leadership.

Dan Price came close to closing up shop himself in 2008 when the recession sent two of his biggest clients into bankruptcy, eliminating 20 percent of his revenue in the space of two weeks. He said the firm managed to struggle through without layoffs or raising prices. His staff, most of them young, stuck with him.

Mr. Price said he wasn’t seeking to score political points with his plan. From his friends, he heard stories of how tough it was to make ends meet even on salaries that were still well-above the federal minimum of $7.25 an hour.

“They were walking me through the math of making 40 grand a year,” he said, then describing a surprise rent increase or nagging credit card debt.

“I hear that every single week,” he added. “That just eats at me inside.”

Mr. Price said he wanted to do something to address the issue of inequality, although his proposal “made me really nervous” because he wanted to do it without raising prices for his customers or cutting back on service.

Of all the social issues that he felt he was in a position to do something about as a business leader, “that one seemed like a more worthy issue to go after.”

He said he planned to keep his own salary low until the company earned back the profit it had before the new wage scale went into effect.

Hayley Vogt, a 24-year-old communications coordinator at Gravity who earns $45,000, said, “I’m completely blown away right now.” She said she has worried about covering rent increases and a recent emergency room bill.

“Everyone is talking about this $15 minimum wage in Seattle and it’s nice to work someplace where someone is actually doing something about it and not just talking about it,” she said.

The happiness research behind Mr. Price’s announcement on Monday came from Angus Deaton and Daniel Kahneman, a Nobel Prize-winning psychologist. They found that what they called emotional well-being — defined as “the emotional quality of an individual’s everyday experience, the frequency and intensity of experiences of joy, stress, sadness, anger, and affection that make one’s life pleasant or unpleasant” — rises with income, but only to a point. And that point turns out to be about $75,000 a year.

Of course, money above that level brings pleasures — there’s no denying the delights of a Caribbean cruise or a pair of diamond earrings — but no further gains on the emotional well-being scale.
As Mr. Kahneman has explained it, income above the threshold doesn’t buy happiness, but a lack of money can deprive you of it.
Phillip Akhavan, 29, earns $43,000 working on the company’s merchant relations team. “My jaw just dropped,” he said. “This is going to make a difference to everyone around me.”

At that moment, no Princeton researchers were needed to figure out he was feeling very happy.

Is In-Flight Refueling Coming to Commercial Airlines?




Excerpt from space.com

This article was originally published on The Conversation. The publication contributed this article to Space.com's Expert Voices: Op-Ed & Insights.

There’s real pressure on the aviation industry to introduce faster, cheaper and greener aircraft, while maintaining the high safety standards demanded of airlines worldwide.

Airlines carry more than three billion passengers each year, which presents an enormous challenge not only for aircraft manufacturers but for the civil aviation infrastructure that makes this extraordinary annual mass-migration possible. Many international airports are close to or already at capacity. The International Air Transport Association (IATA) has estimated that, without intervention, many global airports – including major hubs such as London Heathrow, Amsterdam Schiphol, Beijing and Dubai – will have run out of runway or terminal capacity by 2020. 


The obvious approach to tackling this problem is to extend and enlarge airport runways and terminals – such as the long-proposed third runway at London Heathrow. However there may be other less conventional alternatives, such as introducing in-flight refuelling for civil aircraft on key long-haul routes. Our project, Research on a Cruiser-Enabled Air Transport Environment (Recreate), began in 2011 to evaluate whether this was something that could prove a viable, and far cheaper, solution.

If in-flight refuelling seems implausible, it’s worth remembering that it was first trialed in the 1920s, and the military has continued to develop the technology ever since. The appeal is partly to reduce the aircraft’s weight on take-off, allowing it to carry additional payload, and partly to extend its flight range. Notably, during the Falklands War in 1982 RAF Vulcan bombers used in-flight refuelling to stage what was at the time the longest bombing mission ever, flying 8,000 miles non-stop from Ascension Island in the South Atlantic to the Falklands and back.

Reducing take-off weight could offer many benefits for civilian aircraft too. Without the need to carry so much fuel the aircraft can be smaller, which means less noise on take-off and landing and shorter runways. This opens up the network of smaller regional airports as new potential sites for long-haul routes, relieving pressure on the major hubs that are straining at the seams.

There are environmental benefits too, as a smaller, lighter aircraft requires less fuel to reach its destination. Our initial estimates from air traffic simulations demonstrate that it’s possible to reduce fuel burn by up to 11% over today’s technology by simply replacing existing global long-haul flight routes with specifically designed 250-seater aircraft with a range of 6,000nm after one refuelling – roughly the distance from London to Hong Kong. This saving could potentially grow to 23% with further efficiencies, all while carrying the same number of passengers the same distance as is possible with the current aircraft fleet, and despite the additional fuel burn of the tanker aircraft.

Tornado fighter jets in-flight refuel
Imagine if these Tornado fighter jets were 250-seater passenger aircraft and you’ve got the idea.

However, this is not the whole picture – in-flight refuelling will require the aerial equivalent of petrol stations in order to deliver keep passenger aircraft in the sky. With so much traffic it simply wouldn’t be possible to refuel any aircraft any time, anywhere it was needed. The location of these refuelling zones, coupled with the flight distance between the origin and destination airports can greatly affect the potential benefits achievable, possibly pulling flights away from their shortest route, and even making refuelling on some routes impossible – if for example the deviation to the nearest refuelling zone meant burning as much fuel as would have been saved.

Safety and automation

As with all new concepts – particularly those that involve bringing one aircraft packed with people and another full of fuel into close proximity during flight – it’s quite right to ask whether this is safe. To try and answer this question, the Dutch National Aerospace Laboratory and German Aerospace Centre used their flight simulators to test the automated in-flight refuelling flight control system developed as part of the Recreate project.

One simulator replicated the manoeuvre from the point of view of the tanker equipped with an in-flight refuelling boom, the other simulated the aircraft being refuelled mid-flight. Critical test situations such as engine failure, high air turbulence and gusts of wind were simulated with real flight crews to assess the potential danger to the operation. The results were encouraging, demonstrating that the manoeuvre doesn’t place an excessive workload on the pilots, and that the concept is viable from a human as well as a technical perspective.

So far we’ve demonstrated the potential aerial refuelling holds for civilian aviation, but putting it into practice would still pose challenges. Refuelling hubs would need to be established worldwide, shared between airlines. There would need to be fundamental changes to airline pilot training, alongside a wider public acceptance of this departure from traditional flight operations.

However, it does demonstrate that, in addition to all the high-tech work going into designing new aircraft, new materials, new engines and new fuels, the technology we already have offers solutions to the long-term problems of ferrying billions of passengers by air around the world.

New research shows Universe expansion pace isn’t as fast as assumed earlier



universe


Excerpt from thewestsidestory.net

The Universe is expanding and any student of astronomy will vouch to this fact. However according to a team of astronomers the acceleration of the universe may not be as quick as it was assumed earlier.

A team of astronomers have discovered that certain types of supernova are more varied than earlier thought of and in the process have led to the biggest mystery of the universe-how fast is the universe expanding after the big bang?

Peter A. Milne of the University of Arizona said, “We found that the differences are not random, but lead to separating Ia supernovae into two groups, where the group that is in the minority near us are in the majority at large distances — and thus when the universe was younger, there are different populations out there, and they have not been recognized. The big assumption has been that as you go from near to far, type Ia supernovae are the same. That doesn’t appear to be the case.”
The discovery throws new light on the currently accepted view of the universe expanding at a faster and faster rate pulled apart by an unknown force called dark energy this observation resulted in 2011 Nobel Prize for Physics.
Milne said, “The idea behind this reasoning, is that type Ia supernovae happen to be the same brightness — they all end up pretty similar when they explode. Once people knew why, they started using them as mileposts for the far side of the universe.The faraway supernovae should be like the ones nearby because they look like them, but because they’re fainter than expected, it led people to conclude they’re farther away than expected, and this in turn has led to the conclusion that the universe is expanding faster than it did in the past.”
The researchers felt that the accelerating universe can be explained on the basis of color difference in between two groups of supernova leaving less acceleration than earlier assumed and in the process will require lesser dark energy.

Milne said, “We’re proposing that our data suggest there might be less dark energy than textbook knowledge, but we can’t put a number on it, until our paper, the two populations of supernovae were treated as the same population. To get that final answer, you need to do all that work again, separately for the red and for the blue population.

Type la supernovae are considered as a benchmark for far away sources of light they do have a fraction of variability which has limited our knowledge of the size of the universe.
The distance of objects with the aid of our binocular vision and the best space-based telescopes and most sophisticated techniques works out in the range of ten or twenty thousand light years. 
However as compared to the vastness of space, this is just pea nuts.
For Distances greater than that it is imperative to compare the absolute and observed brightness of well understood objects and to use the difference to determine the object’s distance.

In astronomy it is difficult to find an object of known brightness since there are examples of both bright and dim stars and galaxies. However there is one event which can be used to work out its absolute brightness. Supernovas are the final stages of a dying star and it explodes with such violence, the flash can be seen across the vast universe.

Type la Supernovae occurs in a binary star system when a white dwarf scoops off mass from its fellow star. This reproducible mechanism gives a well determined brightness and therefore scientists term such Type la supernovae as ‘standard candles’.

Astronomers found that the Type la supernovae is so uniform that it has been designated as cosmic beacons and used to assess the depths of the universe. It is now revealed that they fall into different populations and are not very uniform as previously thought. .

How the Secession Movement Could Break Up the U.S.



new U.S. map
Excerpt from charismanews.com  
A new map of the U.S. could include a state called Jefferson, made up of Northern California and Southern Oregon, a new state called Western Maryland and a new state called North Colorado. (CBN)

If you mention the word secession most people think of the South during the Civil War. But today, a new movement is gaining steam because of frustration over a growing, out-of-control federal government.
A number of conservative, rural Americans are taking about seceding and creating their own states, meaning a new map of the United States of America could include the following:
  • A 51st state called Jefferson, made up of Northern California and Southern Oregon
  • A new state called Western Maryland
  • A new state called North Colorado
These are real movements gaining traction with voters across the country. Jeffrey Hare runs the 51st State Initiative in Colorado, an effort to fight an out-of-control legislature trying to ram big government policies down the throats of voters.
"We're at this point of irreconcilable differences," Hare told CBN News.





Secessionist talk has filled town hall meetings and the divide discussed is not just ideological.
"It's predominately left versus right, but it's urban versus rural because you typically find more typical conservative values in rural America," Hare said.
An Attack on Colorado?
That's the crux of the issue. Rural Americans across many states feel they're not being heard. Their laundry list is long and at the top of that list are stricter gun control laws.
According to Weld County, Colo., Sheriff John Cooke, the state legislature is out of control.
"They are out of touch with rural Colorado," he said. "There is an attack on rural Colorado and it's not just on gun control laws. It's on several of the other bills that they passed."
Government mandates on renewable energy, environmental policies restricting oil and gas drilling, and controversial social issues like gay marriage have also led to this divide and talk of secession.
Organizers want to create "North Colorado," an idea that went to voters in 11 counties this past fall. But not everyone in Colorado thinks secession is a great idea.
"I don't think that's necessarily the way to make something happen within the area you live," Colorado resident Greg Howe told CBN News. "You're supposed to work within our electoral services."
The so-called secession movement in Colorado had mixed results this past November. Some counties approved it. Others didn't.
But the organizers of the 51st State Initiative are undaunted, saying this type of movement takes time.
"Movements take a while; education takes time," Hare said. "People do have a hard time saying ,'I want to live in a different state,' even though physically they live in the same house."
"It's hard for them since their lives have been Coloradoans," he explained. "Their whole lives to say that 'I'm going to be a new Coloradoan' or 'I want to live in the state of liberty' or something different."
An 'Amicable' Divorce
That desire for something different can also be felt in Arizona, Michigan, and in Western Maryland where thousands have signed secession petitions.
One website reads, "We intend to exercise our right of self-determination and self-governance to better secure our rights to life, liberty, and the pursuit of happiness."

Scott Strzelczyk, the leader of the Western Maryland movement, is ready to get going.
"If they are not going to listen or take our needs into consideration and govern in a way that's more in accordance with the way we want to be governed we are seeking an amicable divorce," he said.
Meanwhile, in Northern California and Southern Oregon, activists want to come together in the state of "Jefferson."
Their proposed state flag includes two "Xs," representing their feeling of being double-crossed by the state capitals of Sacramento, Calif., and Salem, Ore.
No Small Task
Creating a new state isn't easy. The last time a state actually gave up territory was in 1820, when Maine split from Massachusetts. Since then, additional efforts have been unsuccessful. 
The first step is getting it passed by the state legislature and then the U.S. Congress.
"This is a valid constitutional process that our founding fathers specifically wrote into the Constitution," Hare said. "Well, if they didn't write this into the Constitution to be used, then why did they write it in?"
But supporters have an uphill battle since the media will not be their friend.
"The danger is once the outside media start to grab hold of it, the attention is on the difficulty, the almost impossibility of it happening," professor Derek Everett, with Metropolitan State University in Denver, explained.
Voter 'Disconnect'
State secession proponents, like Roni Bell Sylvester of Colorado, say they will keep fighting because the dismissive attitude of state legislative bodies must end.
"I find the sort of arrogant, dismissive to be further proof as to just how disconnected the urban is from the rural," Sylvester said.
Movements like the one in Colorado and other states could be just the beginning—at least that's the talk at town hall meetings in places like Colorado and elsewhere.
It's called 'voter disconnect" where the people say they've had enough and are crying out for something to be done.
"We, at some point, have to figure out a way to get our point across or at least be able to have a dialogue and not be ignored because you haven't seen anything yet over the next 5 to 10 years," one resident warned at a recent town hall meeting in Colorado.
As for Hare, he said it boils down to one simple concept.
"I think ultimately what people want, whether you look at it from a right or left paradigm, is government to stay out of their business," he said.

Frustrated magnets showing features of Hall Effect stun Princeton University researchers


Frustrated-Magnets



Excerpt from worldtechtoday.com

A group of researchers at the Princeton University has found that frustrated magnets, inspite of not possessing any magnetic feature at low temperatures, do exhibit features of Hall Effect. ‘Frustrated’ magnets are so called because of their inability of getting a long range magnetic order inspite of a huge exchange between the spins of their elementary particles.

The Hall Effect suggests that when magnetic field is applied to electric current carried by charged particles present in a conductor, it causes magnet to bend to the other side of semi-conductor. They are of great interest in physics and material science. Appreciating that frustrated magnets are capable of producing Hall Effect could hold the key to future advances in computing and the creation of devices such as quantum computers.

“To talk about the Hall Effect for neutral particles is an oxymoron, a crazy idea,” said N. Phuan Ong, one of the authors of the study and Eugene Higgins Professor of Physics at Princeton.

Inspite of that, he together with his colleague, Princeton’s Russell Wellman Moore Professor of Chemistry as well as their graduate students Max Hirschberger and Jason Krizan witnessed this unusual behavior in frustrated magnets.

“All of us were very surprised because we work and play in the classical, non-quantum world. Quantum behavior can seem very strange, and this is one example where something that shouldn’t happen is in reality there. It really exists,” said Ong in a statement.
The researchers wanted to find out the reason underlying “discontent” nature of Hall Effect.

In this particular case, the team led by Ong and Moore studied pyrochlores, a class of magnets ‘which should have orderly “spins” at very low temperature, but have been found to have spins that point in random directions, thus rendering them with magnetic frustration properties.’ They attached small electrodes to both sides of crystals and later passed heat through them using microheaters at extremely low temperatures.

The outcome of the experiment, states Ong, stunned the entire team.

Why the U.S. Gave Up on the Moon

Moon nearside



Excerpt from spacenews.com


Recently, several space advocacy groups joined forces to form the Alliance for Space Development. Their published objectives include a mention of obvious near-term goals such as supporting the commercial crew program, transitioning from use of the International Space Station to future private space stations and finding ways to reduce the cost of access to space.  What is notably missing from these objectives and those of many other space agencies, companies and advocacy groups is any mention of building a permanent settlement on the moon. It’s as if the lunar surface has become our crazy uncle that we all acknowledge exists but we’d prefer not to mention (or visit).  What made the next logical step in mankind’s progression beyond the bounds of Earth such a taboo subject?  If, as the Alliance for Space Development suggests, our nation wishes to move toward a path of permanent space settlements, the most logical step is our own planet’s satellite.

A base on the lunar surface is a better place to study space settlement than a space station or Mars for many reasons. Unlike a space station, the base does not have to contend with aerodynamic drag, attitude control issues or contamination and impingement from its own thrusters. Unlike a space station, which exists in a total vacuum and resource void, a lunar base has access to at least some surface resources in the forms of minerals, albeit fewer than might be available on Mars.  Many people naturally want to go directly to Mars as our next step. Even SpaceX has publicly stated this as its ultimate goal, with SpaceX President Gwynne Shotwell noting that “we’re not moon people.” However, Mars makes sense only if we think the technology is ready to safely support humans on another surface for long periods of time. Furthermore, budget restrictions make an ambitious goal like going immediately to Mars an unlikely prospect. Why are we afraid to take the seemingly necessary baby steps of developing the technology for a long-term base on a surface that can be reached in mere days instead of months?  The tendency to want to skip a lunar settlement is not a new phenomenon. Even before the first landing on the moon, U.S. and NASA political leadership was contemplating the future of manned space, and few of the visions involved a lunar base. The early space program was driven by Cold War competition with Moscow, and the kinds of ideas that circulated at the time involved milestones that seemed novel such as reusable spaceplanes, nuclear-powered rockets, space stations and missions to Mars. 

When the United States was on the verge of a series of landings on the moon, building a permanent base just didn’t seem like much of a new giant leap. NASA's ConstellationNASA’s Constellation program, featuring the Orion manned capsule set atop the Ares 1 launch vehicle, was meant to send astronauts back to the moon. Credit: NASA  The idea of a lunar landing mission was not reintroduced seriously until the George W. Bush administration and the introduction of the Constellation program. This program came at a complex time for NASA: The space shuttle was recovering from the Columbia disaster, the space station was in the midst of construction and the United States found itself with large budget deficits. However, despite its budgetary and schedule problems, which are common in any serious aerospace development project from space programs to jumbo-jet development, it provided NASA with a vision and a goal that were reasonable and sensible as next steps toward a long-term future of exploration beyond Earth. 

Constellation was nevertheless canceled, and we have since returned to a most uncommon sense.  The decision to avoid any sort of lunar activity in current space policy may have been biased by the Obama administration’s desire to move as far away as possible from the policies of the previous administration. 

Regardless of the cause, discussion of returning to the moon is no longer on the table.  Without the moon, the only feasible mission that NASA could come up with that is within reach given the current technology and budget is the Asteroid Redirect Mission.  
Even planetary scientists have spoken out against the mission, finding that it will provide little scientific value. It will also provide limited engineering and technology value, if we assume that our long-term goal is to permanently settle space. The experience gained from this sort of flight has little applicability to planetary resource utilization, long-term life support or other technologies needed for settlement.  

If we are to have a program of manned space exploration, we must decide what the long-term goals of such a program should be, and we should align our actions with those goals. When resources such as funding are limited, space agencies and political leaders should not squander these limited resources on missions that make no sense. Instead, the limited funding should be used to continue toward our long-term goals, accepting a slower pace or slight scale-back in mission scope.  Establishing a permanent human settlement in space is a noble goal, one that will eventually redefine humanity. Like explorers before us, it is also not a goal that will be achieved in a short period of time. We would be wise to keep our eyes on that goal and the road needed to get us there. And the next likely stop on that road is a permanent home just above our heads, on the surface of the brightest light in the night sky.

NASA’s Plan to Give the Moon a Moon


arm-capture_0




Excerpt from wired.com

It sounds almost like a late ’90s sci-fi flick: NASA sends a spacecraft to an asteroid, plucks a boulder off its surface with a robotic claw, and brings it back in orbit around the moon. Then, brave astronaut heroes go and study the space rock up close—and bring samples back to Earth.
Except it’s not a movie: That’s the real-life idea for the Asteroid Redirect Mission, which NASA announced today. Other than simply being an awesome space version of the claw arcade game (you know you really wanted that stuffed Pikachu), the mission will let NASA test technology and practice techniques needed for going to Mars.
The mission, which will cost up to $1.25 billion, is slated to launch in December 2020. It will take about two years to reach the asteroid (the most likely candidate is a quarter-mile-wide rock called 2008 EV5). The spacecraft will spend up to 400 days there, looking for a good boulder. After picking one—maybe around 13 feet in diameter—it will bring the rock over to the moon. In 2025, astronauts will fly NASA’s still-to-be-built Orion to dock with the asteroid-carrying spacecraft and study the rock up close.
Although the mission would certainly give scientists an up-close opportunity to look at an asteroid, its main purpose is as a testing ground for a Mars mission. The spacecraft will test a solar electronic propulsion system, which uses the power from solar panels to pump out charged particles to provide thrust. It’s slower than conventional rockets, but a lot more efficient. You can’t lug a lot of rocket fuel to Mars.
Overall, the mission gives NASA a chance at practicing precise navigation and maneuvering techniques that they’ll need to master for a Mars mission. Such a trip will also require a lot more cargo, so grabbing and maneuvering a big space rock is good practice. Entering lunar orbit and docking with another spacecraft would also be helpful, as the orbit might be a place for a deep-space habitat, a rendezvous point for astronauts to pick up cargo or stop on their way to Mars.
And—you knew this part was coming, Armageddon fans—the mission might teach NASA something about preventing an asteroid from striking Earth. After grabbing the boulder, the spacecraft will orbit the asteroid. With the added heft from the rock, the spacecraft’s extra gravity would nudge the asteroid, creating a slight change in trajectory that NASA could measure from Earth. “We’re not talking about a large deflection here,” says Robert Lightfoot, an associate administrator at NASA. But the idea is that a similar technique could push a threatening asteroid off a collision course with Earth.
NASA chose this mission concept over one that would’ve bagged an entire asteroid. In that plan, the spacecraft would’ve captured the space rock by enclosing it in a giant, flexible container. The claw concept won out because its rendezvous and soft-landing on the asteroid will allow NASA to test and practice more capabilities in preparation for a Mars mission, Lightfoot says. The claw would’ve also given more chances at grabbing a space rock, whereas it was all or nothing with the bag idea. “It’s a one-shot deal,” he says. “It is what it is when we get there.” But the claw concept offers some choices. “I’ve got three to five opportunities to pull one of the boulders off,” he says. Not bad odds. Better than winning that Pikachu

Ancient supernova had enough dust to make 7,000 earths


The Cassiopeia A nebula is the gaseous remnant of a supernova explosion whose light reached the Earth around the year 1680.


Excerpt from sciencerecorder.com


A recent discovery has revealed that a supernovae is capable enough producing such quantities of cosmic dust that it can yield thousands of Earths.

An international team of researchers analyzed data obtained by SOFIA – a NASA and German Aerospace Center’s Stratospheric Observatory for Infrared Astronomy project – which took images of a cosmic dust cloud.

“This discovery is a special feather in the cap for SOFIA, demonstrating how observations made within our own Milky Way galaxy can bear directly on our understanding of the evolution of galaxies billions of light years away,” said Pamela Marcum, one of the researchers.

The team made measurements of long infrared wavelengths of the Supernova Remnant Sagittarius A East, gaining an estimate for the total mass of dust within the cloud based on what it released.
SOFIA, an enhanced Boeing 747 with high end telescope, flies in altitudes between 39,000 to 45,000 feet to capture its images.

Astronomers already knew that the shock waves of supernovas produce high concentrations of dust when they move outward.
The question was whether the cosmic particles could withstand the intense shock waves.

“The dust survived the later onslaught of shock waves from the supernova explosion, and is now flowing into the interstellar medium where it can become part of the ‘seed material’ for new stars and planets,” said Ryan Lau, of Cornell University, who led the research team.

This new discovery encouraged the idea that the vast quantities of dust seen in remote yet fairly young galaxies may have been produced by the explosions of large stars that were actually much older.

The research was published in Science magazine on Thursday.
