NASA Snaps Photos of Upcoming "Comet of the Century" - Video
NASA is getting ready to ride the winds of space on sails lighter than gossamer, yet large enough to cover a small field. The space agencys Solar Sail Demonstration, also known as the Sunjammer Project, may launch as early as 2014 when it will send the largest solar sail yet built into orbit, to demonstrate the technical viability of the device.
Sunjammer and the term solar sailing were coined by Sir Arthur C. Clarke in his 1964 short story, The Sunjammer. Its an idea that goes back to Johannes Kepler, though it was James Clerk Maxwell whose theory of electromagnetic fields and radiation showed that a sail could be pushed by sunlight.
Its an unbelievably tiny push, so the payload must be very small and the sails very large and light, but over time it can really add up. A typical spacecraft on the way to Mars can be pushed as much as 1,000 kilometers during the journey even without solar sails. NASAs Messenger probe, for example, used its solar panels as sails for making course corrections.
The basic design of a solar sailing spacecraft is an ultralight mirrored Mylar sail controlled by spider thread-like lanyards, that is propelled by the pressure of light from the sun. The term solar sailing is apt because the principle is exactly the same as with nautical sailing, with the same maneuvers of tacking, luffing and running before the "wind." The hard part is coming up with a design that is light enough to be pushed by sunlight, yet that can maintain its shape without collapsing, so solar sails tend to be either web-like affairs or spun to keep their shape through centrifugal force.
In Sir Arthurs short story, the solar sails were used to propel manned space yachts in a race around the Moon. NASA is much less ambitious. The Sunjammers "In-Space Demonstration of a Mission-Capable Solar Sail" is intended simply to test the feasibility of solar sails, and the design of the unmanned craft reflects this. Its seven times larger and weighs ten times less than previous solar sails. Measuring approximately 124 feet (38 m) on a side, it covers almost 13,000 square feet (1207 m) or a third of an acre. Despite this, it weighs only 70 pounds (32 kg) and collapses to the size of a dishwasher. It uses vanes for attitude control, and the total force that its designed to deal with is only about 0.01 newton or around the weight of a packet of artificial sweetener.
Sunjammer is being built by L'Garde Inc. of Tustin, California in association with the National Oceanic and Atmospheric Administration. Its design advances on 2005-2006 vacuum chamber ground tests by LGarde at NASAs Plum Brook Facility in Sandusky, Ohio, and the deployment of the 100-square foot (9.2 m) NanoSail-D sail in Earth orbit in early 2011.
The Sunjammer will go into Earth orbit as a secondary payload on a Falcon 9 rocket. Once in orbit, the Sunjammer will unfurl its sail and then it will go through its paces as the attitude controls, sail stability and trim are tested and a navigation sequence is executed.
According to NASA, the Sunjammer technology is suitable for a wide range of missions including deployment of space weather systems to warn satellites of solar storms, and as a means of cleaning up space debris, hovering at high altitudes, and propelling deep space missions.

A veteran NASA comet probe turned its sights on a new target, comet C/2012 S1 (ISON), which is barreling toward a close encounter with the sun this fall.
Though Comet ISON is still more 470 million miles away (located just inside the orbit of Jupiter), it already has formed a tail of glowing dust and gas stretching some 40,000 miles from the comets body.
ANALYSIS: New Comet Discovered Will It Be Spectacular?
Scientists are hopeful the comet, which is believed to be making its first pass into the inner solar system, may put on a spectacular show for Earthlings between November and January 2014 after it comes as close as about 1.1 million miles to the sun.
Comet ISON, which was discovered in September by two amateur astronomers using the International Scientific Optical Network (ISON) near Kislovodsk, Russia, was imaged by NASAs Deep Impact spacecraft in January. The 36-hour observation shows the dim but distinct point of light moving against a sea of bright background stars.
ANALYSIS: Incoming ISON to be Dazzling Daytime Comet?
Comet ISON is not Deep Impacts first experience with a comet. The spacecraft, which was launched in January 2005, released a small metal probe to impact the heart of Comet Tempel 1 in July 2005, then flew by for close-up studies.
Five years later and re-purposed for a new mission, it soared past Comet Hartley 2. Deep Impact is now on its way to a January 2020 visit to an asteroid.

Feb. 5, 2013 NASA's Deep Impact spacecraft has acquired its first images of comet C/2012 S1 (ISON). The images were taken by the spacecraft's Medium-Resolution Imager over a 36-hour period on Jan. 17 and 18, 2013, from a distance of 493 million miles (793 million kilometers). Many scientists anticipate a bright future for comet ISON; the spaceborne conglomeration of dust and ice may put on quite a show as it passes through the inner solar system this fall.
"This is the fourth comet on which we have performed science observations and the farthest point from Earth from which we've tried to transmit data on a comet," said Tim Larson, project manager for the Deep Impact spacecraft at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "The distance limits our bandwidth, so it's a little like communicating through a modem after being used to DSL. But we're going to coordinate our science collection and playback so we maximize our return on this potentially spectacular comet."
Deep Impact has executed close flybys of two comets -- Tempel 1 and Hartley 2 -- and performed scientific observations on two more -- comet Garradd and now ISON. The ISON imaging campaign is expected to yield infrared data, and light curves (which are used in defining the comet's rotation rate) in addition to visible-light images. A movie of comet ISON was generated from initial data acquired during this campaign. Preliminary results indicate that although the comet is still in the outer solar system, more than 474 million miles (763 million kilometers) from the sun, it is already active. As of Jan. 18, the tail extending from ISON's nucleus was already more than 40,000 miles (64,400 kilometers) long.
Long-period comets like ISON are thought to arrive from the solar system's Oort cloud, a giant spherical cloud of icy bodies surrounding our solar system so far away its outer edge is about a third of the way to the nearest star (other than our sun). Every once in a while, one of these loose conglomerations of ice, rock, dust and organic compounds is disturbed out of its established orbit in the Oort cloud by a passing star or the combined gravitational effects of the stars in the Milky Way galaxy. With these gravitational nudges, so begins a comet's eons-long, arching plunge toward the inner solar system.
ISON was discovered on Sept. 21, 2012, by two Russian astronomers using the International Scientific Optical Network's 16-inch (40-centimeter) telescope near Kislovodsk. NASA's Near-Earth Object Program Office, based at JPL, has plotted its orbit and determined that the comet is more than likely making it first-ever sweep through the inner solar system. Having not come this way before means the comet's pristine surface has a higher probability of being laden with volatile material just spoiling for some of the sun's energy to heat it up and help it escape. With the exodus of these clean ices could come a boatload of dust, held in check since the beginnings of our solar system. This released gas and dust is what is seen on Earth as comprising a comet's atmosphere (coma) and tail.
ISON will not be a threat to Earth -- getting no closer to Earth than about 40 million miles on Dec. 26, 2013. But stargazers will have an opportunity to view the comet's head and tail before and after its closest approach to the sun -- if the comet doesn't fade early or break up before reaching the sun.
Launched in January 2005, NASA's Deep Impact spacecraft traveled about 268 million miles (431 million kilometers) to the vicinity of comet Tempel 1. On July 3, 2005, the spacecraft deployed an impactor that was essentially "run over" by the nucleus of Tempel 1 on July 4. Sixteen days after comet encounter, the Deep Impact team placed the spacecraft on a trajectory to fly past Earth in late December 2007. This extended mission of the Deep Impact spacecraft culminated in the successful flyby of comet Hartley 2 on Nov. 4, 2010. In January of 2012, the spacecraft performed, from a distance, an imaging campaign on comet C/2009 P1 (Garradd).
To date, Deep Impact has traveled about 4.39 billion miles (7.06 billion kilometers) in space.
JPL, a division of the California Institute of Technology in Pasadena, manages the Deep Impact mission for NASA's Science Mission Directorate, Washington. The mission is part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Ala. The spacecraft was built for NASA by Ball Aerospace & Technologies Corp., Boulder, Colo.

NASA's Deep Impact space probe has captured video of a comet which could outshine the moon when it passes through the inner solar system this autumn.
The three-kilometre-wide comet was discovered by two Russian astronomers last September.
NASA astronomers have plotted its orbit, and say its likely the object has never visited the inner solar system before.
That means it's more likely that the comet's surface will produce a bright 'tail' of gas and dust in the radiation from the sun.
"If it lives up to expectations, this comet may be one of the brightest in history," Raminder Singh Samra of the H R MacMillan Space Centre in Canada said when the comet was first seen.
Many scientists anticipate a bright future for comet ISON; the spaceborne conglomeration of dust and ice may put on quite a show as it passes through the inner solar system this fall.

NASA
Feel like exercising your math skills to virtually manage the nations crowded airways? Yup, theres an app for that and has been for about a year now.
But until now, the popular NASA-developed game app called Sector 33, which gives you a sense of what its like to be an air traffic controller, was only available for mobile device owners who use the Apple-based iOS operating system.
Now Sector 33 is available to a wider audience of students and adults alike with its recent release of a version for the Android operating system, which you can download for free at GooglePlay.
We didnt want to overlook the millions of students who have access to and use Android-based devices, so now they too can enjoy the educational and entertaining Sector 33 app, and perhaps be inspired to pursue a career in aviation, said Rebecca Green, lead for the Smart Skies project at NASAs Ames Research Center in California.
In the game, the player acts as an air traffic controller by guiding airplanes through a sector of airspace spanning Nevada and California.
The player can adjust the planes path and speed to quickly reach certain spots in the sky, while at the same time keeping the planes a safe distance from each other obviously a key objective of real-life Air Traffic Control (ATC).
To achieve a perfect score, players must apply a little math and use problem-solving skills as they balance time, aircraft positions and safety.

A NASA spacecraft has captured its first photos of comet ISON, an icy wanderer that some scientists say could dazzle as a "comet of the century" when it swings through the inner solar system later this year.
The photos were taken by NASA's Deep Impact probe and reveal comet ISON as a bright, dusty ball moving against a star-filled background. The spacecraft snapped the pictures on Jan. 17 and Jan. 18 from a distance of about 493 million miles (793 million kilometers).
Comet ISON has been the focus of much anticipation among scientists and stargazers because of its potential to put on a spectacular display in late November, when it makes its closest approach to the sun. Some forecasts predict the comet could shine brighter than the full moon. As of mid-January, the comet's tail was more than 40,000 miles (64,400 km).
Will comet ISON sizzle or fizzle?
Some projections state that comet ISON, which is officially designated comet C/20012 S1 (ISON), could shine extremely bright in the nighttime sky, possibly even rivaling the full moon. Whether the comet will meet expectations or fizzle out remains to be seen, but it has already become a target for NASA and amateur astronomers. [Photos of Comet ISON in Night Sky]

The Deep Impact spacecraft has flown close by two comets, Tempel 1 and Hartley 2, and taken detailed observations of another comet Garradd before turning its camera eyes on Comet ISON. The spacecraft used its Medium-Resolution Imager to snap pictures of ISON during a 36-hour period between Jan. 17 and 18, NASA officials said.
Comet ISON was discovered in September 2012 by Russian astronomers Vitali Nevski and Artyom Novichonok using a 15.7-inch (0.4-meter) telescope of the International Scientific Optical Network (ISON), near Kislovodsk. The comet is most likely making its first trip through the inner solar system from the Oort cloud, a vast shell of icy objects at the outer edge of the solar system that extends one-third of the way to the nearest star, NASA scientists said.
"Having not come this way before means the comet's pristine surface has a higher probability of being laden with volatile material just spoiling for some of the sun's energy to heat it up and help it escape," NASA officials wrote in a statement. "With the exodus of these clean ices could come a boatload of dust, held in check since the beginnings of our solar system.

Nano Track - Self cleaning coating on glass with nanotechnology, test with dirty water
Nano Track offers a coating that makes most surfaces become almost maintenance free and easily cleaned. This is because the coating makes the surface water repellent (hydrophobic) with very strong anti-stick properties. Because of this, dirt is picked up by water and then gets carried away. It also means that fouling can #39;t grow on the surface. The coating is weather and UV resistant and it even withstands temperature changes, both plus and minus over time. This probably leads to an extended lifetime of the product. In regards to health, environmenta and safety our coating does not contain any nanoparticles. We use SiO2 liquid and it is called "nano" because of it #39;s thickness which is below 100nm (nm = nanometer). The coating works with small modifications on glass, glazed ceramics, plastic, painted surfaces like automotive paint, precious metals, textile, microporous surfaces and stone (mineral surfaces).

Purdue University announced Tuesday that some of its researchers won a five-year, $14.5 million grant from the National Science Foundation to expand the schools online gateway for instruction, research and simulations in nanotechnology.
The nanoHUB.org portal already attracts nearly 250,000 users each year, and it provides instructional segments used by 760 classes at 185 universities around the world.
The new funding will be used to expand nanoHUBs resources for running simulations based on experimental data, for offering courses in nanotechnology to train new workers in the field, and to bring in even more users to participate in the nanoHUB community.
"Thousands of times a day the leading researchers 'come' to Purdue through the globally unique tool of nanoHUB," Purdue President Mitch Daniels said in a prepared statement. "The new NSF investment is an affirmation of the brilliance of nanoHUB's Purdue creators and of its worldwide scientific significance."
Purdues has started to build off of nanoHUB to provide more online instruction to students at other universities, potentially creating a new revenue stream at a time when state support for higher education has not kept pace with inflation.
The National Science Foundation helped launch nanHUB with a $10.5 million grant to Purdue and five other universities in 2002. That money was used to create the Network for Computational Nanotechnology and the nanoHUB content.
The National Science Foundation also gave a $3.5 million grant to the University of Illinois.
The Purdue researchers behind nanoHUB are Gerhard Klimeck, Krishna Madhavan, Michael McLennan, Lynn Zentner and Michael Zentner.

STEPHEN VOSS/REDUX/EYEVINE
In his last role two years ago with the Opera Vivente in Baltimore, Maryland, Christopher Austin played the Calvinist chaplain in Gaetano Donizetti's Lucia di Lammermoor. The story does not lack for drama: the heroine pulls out a knife in her wedding bed and stabs to death the husband who has been forced on her in place of her true love. On the heels of the murder, the chaplain is the guy who is trying to bring order to chaos, says Austin, a bass-baritone who once considered a full-time career in opera.
Austin's most recent stage part has a certain resonance with his new day job. In September, he was appointed as director of the fledgling National Center for Advancing Translational Sciences (NCATS) at the US National Institutes of Health (NIH) in Bethesda, Maryland. In existence since December 2011, the centre has an ambitious some say audacious agenda that channels the central passion of both Austin and his boss, NIH director Francis Collins: to get more successful medicines into more patients, more quickly. That means forcing the agonizingly slow, failure-prone process of 'translational research' the term of art for moving promising discoveries from the lab to the clinic into a higher gear.
Passion runs high among the sceptics, too. Researchers both inside and outside the agency fear that NCATS the first new centre at the NIH in more than a decade, funded at US$575 million last year will encroach on a finite pot of money that they say would be better spent probing the mechanisms of basic biology and disease. Others question the scale of its mission. With the available resources, how are you going to achieve this? asks Thomas Caskey, a molecular geneticist at Baylor College of Medicine in Houston, Texas. To me, you cannot just take this money and be another biotechnology company and you certainly don't have enough money to be a pharmaceutical company.
NCATS will be neither, Austin responds. What will set it apart, he says, is a focus on overcoming obstacles on the road to drug development, from inadequate toxicology methods to inefficient clinical-trial recruitment, rather than actually producing the drugs. In an era in which more than 95% of drug candidates fail, and a novel drug takes 13 years and more than $1 billion to develop, NCATS has to be focused on logarithmic improvements in the process, says Austin. You can't do this in a brute-force way. You have to do it differently. You have to drive the technology development.
Austin's fans say that if anyone has a shot at making this work, it is him. This guy has got clinical training, industry training and scientific training. If you wanted me to pick a quarterback, this is the quarterback I'd pick, says Lee Nadler, director of Harvard Catalyst, the NCATS-funded clinical and translational science centre based at Harvard University in Boston, Massachusetts. But whether quarterback or maestro, Austin has now to give the performance of his career. The biggest risk he faces lies in not delivering something concrete within 1224 months, says Nadler. Everybody is watching him.
Austin learned early, and at first-hand, about the tragic shortcomings of medicine. One night in 1989, when he was a neurology resident on call at Massachusetts General Hospital in Boston, an ambulance brought in a middle-aged man with end-stage amyotrophic lateral sclerosis (ALS), a disease that slowly destroys muscle power but leaves brain function intact. Patients usually die when their breathing muscles give out.
The man had a 'do not resuscitate' order, but, because of a miscommunication, he had been revived by the paramedics. Furious that he had not been allowed to die at home, he demanded that his ventilator be turned off. Austin complied. Watched by his family and Austin, the man died slowly over three hours, in the end turning blue before his heart monitor flatlined. It was like sitting through the crucifixion, Austin recalls. And I just said: 'I can't do this. There has got to be a better way.'
Convinced that he had to do more, Austin began a postdoc in the lab of Connie Cepko, a geneticist at Harvard Medical School in Boston. There, he dived into developmental neurology, using new tracing techniques to reveal the migration of neural progenitor cells in the budding mouse cortex (C. P. Austin and C. L. Cepko Development 110, 713732; 1990).
He was just really driven. He absolutely loves research, says Cepko. She recalls the day that Austin's wife went into labour with the couple's first child at the Brigham and Women's Hospital, around the corner. I went to the lab and there was Chris sitting as his bench, pipetting away. I said, 'Chris, aren't you supposed to be in the delivery room?' He said: 'It'll be a couple hours [yet]'.

BOCA RATON, FL--(Marketwire - Feb 6, 2013) - Modernizing Medicine, the creator of the Electronic Medical Assistant (EMA), a cloud-based specialty-specific electronic medical records (EMR) application, announced today that it has been listed at No. 47 on FORBES' annual ranking of America's Most Promising Companies -- a list of one hundred privately held, high-growth companies with bright futures.
"We are honored to be recognized alongside so many innovators as one of America's Most Promising Companies," said Daniel Cane, Modernizing Medicine's President and CEO. "This has been an incredible year of growth for Modernizing Medicine and to receive this award from one of the world's leading business publications is confirmation that our transformative technology is making its mark on the healthcare industry."
FORBES' list of 'America's Most Promising Companies' features 100 privately held up-and-comers that are poised to grow and change the world with their compelling business models, strong management teams, notable customers, strategic partners and dynamic investors.
For the Most Promising list, FORBES strove for a holistic gauge of young, privately-held companies, trying to pin down their trajectories by looking at a slew of variables. Over the course of six months FORBES reviewed thousands of applications. The final assessment is based on growth (both in sales and hiring), quality of management team and investors, margins, market size and key partnerships. FORBES turned to CB Insights, a Manhattan-based data research firm that specializes in assessing private companies, to refine the search. Their MOSAIC software scans 45,000 sources to measure a company's health. A new distribution deal, for example, marks a positive signal, while the loss of an executive is a negative. MOSAIC gathers those myriad signals into a final score that FORBES uses as an initial guide in producing the list. After verifying sales numbers, speaking with each company and debating their merits and blemishes, FORBES produces a final ranking.
Modernizing Medicine's inclusion on FORBES' list comes at the close of an incredible year for the three-year old company. In 2012, Modernizing Medicine grew its customer base by over 1000%, bringing the total number of providers using EMA to over 2,000. Modernizing Medicine also more than doubled its staff, grew its product line with the addition of EMA Plastic Surgery and closed a $12 million dollar capital raise, with a combination of equity capital and a senior debt bank facility. The company was named the #1 Fastest Growing Company in South Florida by the South Florida Business Journal in its "Fast 50," the #1 "Top Mobile Startup in South Florida" by the South Florida Technology Alliance and was named one of the "2012 Florida Companies to Watch" by the Florida Economic Gardening Institute. Daniel Cane was also recognized as a great leader and innovator with '40 Under 40' awards from the South Florida Business Journal and Enterprise Florida, Inc.
Modernizing Medicine is looking forward to an exciting year, with the launch of EMA Cosmetic, EMA Orthopedics and EMA Otolaryngology.

Modernizing Medicine Is Named One of 'America's Most Promising Companies' by FORBES
By Chelsea Conaboy, Globe Staff
Doctors who attended medical schools that limited gifts to students from pharmaceutical companies -- sponsored lunches, for example -- may be less susceptible to drug marketing, a study published last week in the BMJ found.
Researchers from Yale University looked at the prescribing practices of doctors who had attended one of 14 schools that were early adopters of such policies. They looked at how often the physicians prescribed Vyvanse or Invega, two heavily marketed drugs used to treat attention deficit hyperactivity disorder and schizophrenia, over older, similar drugs.
Compared with doctors who attended the same schools before the gift ban was in place and peers from other schools, the physicians were less likely to prescribe the two marketed psychotropic drugs.
Increasingly, medical schools are sharpening policies prohibiting drug marketing on campus as researchers add to the evidence that it can influence physician attitudes and behavior over the long term.
The University of Massachusetts Medical School, for example, enacted a policy in 2008 prohibiting students from accepting gifts from drug and device makers. Harvard Medical School also bans pharmaceutical representatives from visiting campus, and companies cannot sponsor student events.
The Yale study found that the counter-effect on prescribing patterns was greater among students who attended schools with strict policies.
The study did not find a significant effect for a third drug, an antidepressant marketed as Pristiq. It is not clear why, but lead author Marissa King, associate professor of organizational behavior at the Yale University School of Management, said the drug is less commonly prescribed than the other two drugs studied.
The researchers evaluated the effects of gift restrictions only put in place as of 2004. They noted that much has changed since then, with more schools adopting policies or tightening their rules.
King said the study does not evaluate whether such policies could slow the acceptance by young doctors of potentially important new drugs. But, she said, my gut instinct is that if it is actually a radical breakthrough, physicians are going to adopt it anyway.
