NASA's next giant leap
STORY HIGHLIGHTS
(CNN) -- NASA on Thursday morning hopes to enjoy one of its biggest moments since the shuttle era ended in 2011 -- if it can get some kinks worked out.
The space agency's new Orion spacecraft is scheduled to lift off on an uncrewed test flight from Space Launch Complex 37 at Cape Canaveral, Florida. But some delays have so far kept it on the launch pad.
The launch, initially set for 7:05 a.m. ET, was delayed for various reasons, including wind gusts, a boat coming too close to the launch area, and a failure of some fuel valves to close in the booster rockets, NASA said.
Mission managers hope to launch the craft before the day's window closes at 9:44 a.m. ET.
"We haven't had this feeling in awhile, since the end of the shuttle program," Mike Sarafin, Orion flight director at Johnson Space Center, said in a preflight briefing on Wednesday. He said it's the beginning of something new: exploring deep space.

NASA 'go' for its next giant leap
STORY HIGHLIGHTS
(CNN) -- It's the biggest countdown for NASA since the shuttle era ended in 2011. The space agency's new Orion spacecraft is scheduled to lift off on an uncrewed test flight at 7:05 a.m. ET Thursday from Space Launch Complex 37 at Cape Canaveral, Florida.
"We haven't had this feeling in awhile, since the end of the shuttle program," Mike Sarafin, Orion flight director at Johnson Space Center, said in a preflight briefing on Wednesday. He said it's the beginning of something new: exploring deep space.
Orion looks like a throwback to the Apollo era, but it is roomier and designed to go far beyond the moon: to an asteroid and eventually to Mars.
"It is, I think, consistent with those -- the beginning of shuttle and beginning of Apollo," said Mark Geyer, NASA Orion program manager. "I think it's in the same category."

NASA wants to get back in the business of sending astronauts into deep space, including Mars. Today will be a big test for fulfilling those aspirations.
At 7:05a.m. Eastern Time, NASA will launch the first test flight of its Orion spacecraft the chariot that could taxi astronauts to the Red Planet and beyond by the late 2030s. On its unmanned inaugural journey, scientists hope to learn more about the crafts safety systems and durability.
From blast-off to splashdown, Orions entire $370-million journey will be completed in just a matter of hours. Fastened atop a Delta IV Heavy rocket, Orion will reach an altitude of 3,600 miles above Earth 15 times higher than the International Space Station.
After orbiting our planet twice, Orion will reenter Earths atmosphere at 20,000 miles per hour, and its heat shields will need to withstand temperatures of 4,000 degrees Fahrenheit. When the craft finally splashes into the Pacific Ocean it will have covered more than 60,000 miles in a 4.5-hour journey.

NASA plans to conduct a second test run for Orion in 2018, whenthe craft will make a trip around the moon and back. If all goes as expected, and funding stays on track, a manned mission around the moon is slated to occur in 2021.
Moving forward, the craft could carry astronauts to an asteroid in the late 2020s and perhaps to Mars by the late 2030s.
Orion is the future of space exploration at NASA, but it bears a striking resemblance to the cone-shaped spacecraft that ferried Apollo astronauts to the moon and back. Orion is about 30 percent larger than the Apollo capsules, and can house up to six crew members for missions up to 21 days in duration. It can also attach to other craft for extended journeys.

NASA set to launch much anticipated Orion spacecraft

CAPE CANAVERAL, Fla. With the imminent debut of its Orion spacecraft, NASA is on a high not felt since the space shuttle days.
Shuttle veterans, in fact, are leading the charge in Thursday morning's two-orbit, 4-hour test flight, meant to shake out the capsule before astronauts climb aboard eventually, perhaps, to visit Mars.
"We haven't had this feeling in a while, since the end of the shuttle program," said Mike Sarafin, the lead flight director stationed at Mission Control in Houston. "Launching an American spacecraft from American soil and beginning something new, in this case exploring deep space."
Orion is set to fly farther than any human-rated spacecraft since the Apollo moon program, aiming for a distance of 3,600 miles, more than 14 times higher than the International Space Station.
That peak altitude will provide the necessary momentum for a 20,000-mph, 4,000-degree entry over the Pacific. Those 11 short minutes to splashdown is what NASA calls the "trial by fire," arguably the most critical part of the entire test flight. The heat shield at Orion's base, at 16.5 feet across, is the largest of its kind ever built.
Navy ships were stationed near the recovery zone off the Mexican Baja coast.
"It's an exciting time," Jeff Angermeier, ground support mission manager, said from Florida's Kennedy Space Center. "You can feel the buzz."
An estimated 26,000 guests were expected to jam Kennedy for the sunrise launch, as well as 650 journalists. (Actually, the unmanned rocket will blast off from the adjoining Cape Canaveral Air Force Station.) The space center press site was packed Wednesday with out-of-town reporters not seen here since the last shuttle flight in 2011.
NASA's Orion program manager, Mark Geyer, puts the capsule's inaugural run on a par with the formative steps of Apollo and the space shuttles.

NASA's Orion Launch Scrubbed After Setbacks
More ABC US news | ABC World NewsCopy
It seems bad luck does come in threes.
Launch day for NASA's Orion spacecraft was delayed by a trio of problems, including wind gusts, a stray boat in the launch zone and technical issues that prompted the space agency to call it a day.
NASA announced the launch was scrubbed for today, just before the lift off window closed at 9:44 am ET.
The first setback came when NASA said a boat drifted into the launch zone before Orion was scheduled to launch on a Delta IV rocket today at 7:04 am ET.
A new launch time 13 minutes later was again pushed back due to winds.
Less than an hour later, NASA reported that the new launch time of 8:26 am ET would not hold up after a fuel and drain valve did not close. NASA said it was cycling the valves open on three core boosters to see if opening and closing them again would solve the issue.
The Orion space capsule is seen as crucial step toward the dream on one day sending a manned mission to Mars. Once it does lift off, NASA will be watching closely to see how Orion holds up to a series of stress tests in space.
Orion seats four astronauts -- one more than Apollo. While the design may be the similar, Orion is equipped with technology that is light-years ahead of its Moon-shot mission predecessor.
While in orbit, Orion will circle the Earth twice at an altitude of 3,600 miles and will make re-entry at 20,000 mph with temperatures hitting 4,000 degrees Fahrenheit.

Why NASA's Orion Spacecraft Looks So Familiar
As NASA's Orion craft makes its first flight in the decades-long journey to land humans on Mars, the craft will strike many people as a throwback. Squint an eye and the Orion crew module bears a remarkable resemblance to the Apollo craft that ferried astronauts to the moon more than 40 years ago.
NASA's choice of a blunt-bottomed conical capsule design on both spacecraft isn't an accident. Instead, the blunt cone shape causes high drag to help slow the craft as it descends. When it returns to Earth from its farther-flung missions, Orion will be traveling nearly 7 miles per second, or hypersonic speeds multiple times faster than the speed of sound. At that speed, managing the enormous temperatures the craft will generate--in excess of 5,000 degrees F--requires an effective design with intense shielding. That's one reason the initial test flight's prime job is to assess the updated shield built for Orion.
"The 'capsule shape' happens to be good aerodynamically for slowing down the vehicle without it burning up like a meteor," Kelly Smith, a NASA guidance engineer, wrote last month in a public discussion the agency held on Reddit. "Sharp shapes tend to heat up too much and melt/vaporize. A blunt shape works well hypersonically for keeping the heating to more manageable levels. If you look at ballistic missiles, all of their nose cones are 'blunt' as well (spheres, sphere-cones, etc) to deal with the extreme heating environment."
The cone's imbalanced shape also causes the craft to fly "crooked" as it hurtles toward earth at a rate of about five times the speed of sound, Smith explained. "This angle of attack causes Orion to have a little bit of lift; we can use this lift to steer the vehicle and control the entry trajectory by banking Orion like a glider," he wrote. Russia uses a similar shape for its Soyuz capsules, as does SpaceX's Dragon spacecraft.
Weather permitting, Orion is scheduled to launch Thursday morning on a 4.5-hour, two-orbit cycle around Earth, reaching an altitude 15 times higher than the International Space Station. The 3,600-mile altitude will help NASA test the craft's response to the higher radiation found outside low-earth orbit--from which the space shuttle never strayed--and to reach a 20,000 mph entry speed, about 84 percent of the speed a return from the moon generates. "Although our computers have gotten a lot more powerful, the physics of atmospheric entry hasn't changed since Apollo," says NASA spokeswoman Stephanie Schierholz.
The Orion program's homage to Apollo doesn't end with just the basic look. NASA also consulted with several retired employees who worked on the Apollo program, and at least one will be on hand to observe the flight at Mission Control in Texas. Up close, the similarities end abruptly. Orion is roughly three times larger than the Apollo crew module, built to carry four astronauts as far as Mars, a 70-million mile round-trip journey that could take as much as 23 months. On shorter trips, the craft can fit six.
Inside, Orion's "glass cockpit" would not look particularly foreign to any iPad user, with touch screens similar to those used in modern jet cockpits. Eliminating physical switches, and their associated cabling, saves enormously on weight. Only about 60 physical switches remain.

Colorful nano-guides to the liver
23 hours ago Highly specific nanoparticles, that were produced at the University of Jena. Credit: Jan-Peter Kasper/FSU Jena
Jena scientists have been successful in producing highly specific nanoparticles. Depending on the bound dye the particles are guided to the liver or to the kidney and deliver their payload of active ingredients directly to the targeted tissue. Moreover, the dyes enable the tracking of the transport processes by intravital microscopy or, in a non-invasive way, by multi spectral optoacoustic tomography. The reduction of cholesterol production induced by siRNA served as the proof-of-principle for the developed method. The scientists report their data in the new edition of the scientific journal Nature Communications.
They are one of the great hopes for target-oriented treatment approaches: the so-called small interfering RNA-molecules, siRNA. These are able to mute specific genes, by preventing them from producing proteins which are encoded on them. To accomplish this, the siRNA has to be delivered specifically into the targeted cells in order to work only there and nowhere else. Moreover, the siRNA should not be just excreted or, even worse, damage healthy tissue. This is what makes the handling of siRNA extremely difficult. Physicians and chemists from Jena, Munich (both Germany) and the USA have now succeeded in producing nano-transporters for this genetic material which are able to specifically and efficiently target selected cell types and release their active payload there.
Fluorescent dyes are both address labels and tracking numbers all in one
The particles which are based on polymers are marked with near infrared fluorescent dyes and loaded with siRNA. The dyes work like address labels and tracking numbers for the particles all in one. "Depending on the chemical structure of the dye the particles are filtered out of the blood either via the kidney tissue or via liver cells. At the same time this route can easily be tracked by optical methods with the aid of the dyes," says intensive care physician Prof. Dr. Michael Bauer. His research team at the Jena University Hospital Centre for Sepsis Control and Care (CSCC), which is supported by the Federal Ministry of Education and Research, was also able to show that the dye is specifically absorbed by a specific cellular transporter of the liver epithelial cells and taken up into the cells.
Toolbox for nanomedicine
In this way the siRNA load is exclusively released in the target cells. The specifically functionalized nano-containers have been designed and produced in the laboratories of the Jena Center for Soft Matter (JCSM) of the Friedrich Schiller University in Jena. "This method can be regarded as a kind of toolbox for a multitude of different siRNA-nanotransporters which can ensure the targeted ,switchoff' of specific protein biosynthesis in different cell types," the Director of the JCSM, Prof. Dr. Ulrich S. Schubert, states. With the possibility to test the non-coupled dyes in advance and to switch off genes which are associated with illnesses, the principle offers new approaches to a personalized therapy of various diseases. In the newly founded SmartDyeLivery GmbH, the Jena scientists want to further develop the technology to put it into practical use in the clinical environment, especially in cases of acute septic infections.
The Jena nanomedicine researchers explain in their study the working principle of their toolbox using the example of cholesterol production. They loaded the nanoparticles with targeting dyes attached with siRNA-molecules. The siRNA molecules interfered with cholesterol production in hepatocytes, which resulted a clear reduction in the cholesterol level in the blood of test animals. The study is now published in the scientific journal "Nature Communications."

Green meets nano: Scientists create multifunctional nanotubes using nontoxic materials
23 hours ago
A doctoral student in materials science at Technische Universitat Darmstadt is making multifunctional nanotubes of goldwith the help of vitamin C and other harmless substances.
Coffee, apple juice, and vitamin C: things that people ingest every day are experimental material for chemist Eva-Maria Felix. The doctoral student in the research group of Professor Wolfgang Ensinger in the Department of Material Analysis is working on making nanotubes of gold. She precipitates the precious metal from an aqueous solution onto a pretreated film with many tiny channels. The metal on the walls of the channels adopts the shape of nanotubes; the film is then dissolved. The technique itself is not new, but Felix has modified it: "The chemicals that are usually used for this were just too toxic for me." She preferred not to use cyanide, formaldehyde, arsenic and heavy metal salts. She was inspired by a journal article by researchers who achieved silver precipitation using coffee.
Felix also used coffee in her first experiments. She then tested apple juice, followed by vitamin C. This seemed to be the best suited to her because "you never know what's in coffee and apple juice." On the other hand, Vitamin C - or ascorbic acid - is available in pure form from chemical stores - a requirement for reproducible studies. But what does the vitamin have to do with the precipitation of gold? In the human body, vitamin C makes free radicals harmless by transferring electrons to them. "Gold precipitation functions according to the same principle. The only difference is that the vitamin does not take on radicals, but rather gold ions", explains Falk Mnch, a postdoctoral researcher and supervisor of Felix' PhD thesis. The gold ions that are dissolved in the precipitation bath are transformed into metallic gold after absorbing electrons.
Additional, harmless chemicals are required for the process. But the procedure is green not only because of the non-toxic substances, but also because it takes place at room temperature and without an external power supply, thus saving energy. Furthermore, as opposed to other methods, no expensive devices are required. The film with the nanochannels is merely placed in the precipitation bath. "It's really unbelievable that aqueous solutions and simple basic chemicals can produce such precise nanostructures" says Mnch.
"Green meets Nano" is a motto of the researchers at the TU. The only thing that is not green in the procedure is the film that is used as the template, notes Ensinger. Although tests with bio-based plastics are already on the agenda, the films still consist of polycarbonate also made or of polyethylene terephthalate (PET).
In order to create the miniature plastic channels that define the shape, a round film is vertically bombarded with an ion beam. Each ion leaves a straight track in the film which then becomes a small hole, or, when seen through the microscope: a channel that is then etched. Its diameter can be set precisely - down to far less than 100 nanometers. The gold nanotubes are thus several hundred times finer than a human hair. Their wall thickness depends both on the duration of precipitation and on the gold concentration of the original solution. After the film is dissolved, the result is - depending on the experimental conditions - a collection of individual nanotubes or an array of hundreds of thousands of interconnected tubes.
The crux of the technique: an ion accelerator is needed to generate an ion beam. The TU scientists found the ideal partner for their research in the GSI Helmholtz Center for Heavy Ion Research at the outskirts of Darmstadt; but the GSI's large-scale accelerator was not suitable for subsequent commercial use for financial reasons. The TU scientists are already looking for alternatives. For example, a company in the USA produces similarly perforated films with smaller accelerators. "The films are not as well-defined as ours are, but they are also suitable", says Mnch. Furthermore, they are inexpensive: a film roughly the size of a sheet of paper costs only a few euros. Ensinger says that the price of gold is not a factor because the amounts that are required are small: "With 1 gram of gold, we could make a nanotube for literally every person on earth." Although a single tube is not useful for anyone, not much material is needed for microsensors, miniature through-flow reactors, or other potential applications.
Ensinger's team has already successfully tested one use of the gold nanotubes: they are suitable for building sensors to measure hydrogen peroxide. This chemical damages nerve cells and apparently plays a role in neurodegenerative diseases such as Alzheimer's and Parkinson's. A microsensor that can measure hydrogen peroxide in the human body would thus be practical both in medical research as well as for diagnosis. The conversion of hydrogen peroxide to water, catalyzed by the gold releases electrons generates an easily measurable electric current. The gold nanotubes conduct electricity especially well due to their one-dimensional structure. In addition, they are relatively long and are thus more durable than normal nanoparticles.
"Nano meets Life" is the second motto of the TU Materials Science researchers. For example, they are thinking about also using the nanotubes to measure blood sugar. "A subcutaneous sensor could save diabetes patients from having to constantly prick their fingers" thinks Ensinger. The green method of production also has advantages here because the components of such implants should be produced with as few toxic chemicals as possible. "This completes the circle", says the TU professor, combining the two mottos: "Green meets Nano meets Life".

The best internet radio stations
AccuRadio
This beautifully designed, simple to use radio service from Chicago allows listeners to choose from 900-plus radio channels, taking in everything from Miles Davis to Kenny Chesney to Eliott Carter. Its website is ad-funded, so the streams are occasionally interrupted by commercial messages, but not to an annoying level.
The Departure Lounge
Imagine Roger Moore and Tony Curtis gunning their Aston Martins along the Cte dAzure in 1971 and you'll get an idea of what this new station curated by a former TV producer is about. Bossa nova, funk, jazz and soul from the 1960s and 70s dominate the playlists which is no bad thing, providing youre in the mood for some vintage pizazz.
GENERAL LISTENING
FIP
Imagine a mixture of BBC 6 Music and late-night Radio 3, stir in a generous amount of Parisian chic, and youre some way to getting the measure of FIP, which remains one of my favourite music radio stations on the planet. Founded in Paris in 1971, its mission statement was - and remains - to broadcast an eclectic mix of music uninterrupted by the kind of noisy chitchat and advertising that you find almost everywhere else on French radio. They pay particular attention to the way in which songs on their playlist complement each other - meaning no jarring transitions, and plenty of unexpected musical dovetailing - and have an excellent website which makes it easy to see whats been played. Expect to hear everything from Haydn to Serge Gainsbourg to John Coltrane to De La Soul -- and beyond.
WCPE
Branding itself online as The Classical Station, WCPE is an eminently likeable classical music station from North Carolina. Its been listener-supported for over 30 years, and continues to pay for most of its operating costs from pledges and donations which is a sure-fire sign of a station that knows and respects its audience. Their playlists tend towards the popular - rather than the obscure or experimental - end of the classical spectrum, with regular appearances by Mozart, Beethoven, Bach, Handel and Rachmaninoff.

Selling Girl Scout cookies online can have a dark side
After selling Girl Scout cookies the old-fashioned way since she was five, Rebecka Hicks, 16, is taking her firstleap into the world of online sales.
Pretty soon, Rebecka will put up her photo, perhaps a video of her making a sales pitch, on apersonal Web site. She'll send out eCards to reacha wider range of customers than she ever has before. Andwhile the overall design for her sales sitewill come from the Girl Scouts, what goes online is basically up to her. The organizationwon'treview the content, saying that suchprojects should stay between parents and their kids.
The move by the Girl Scouts this week to allow its troopers to sell cookies online has been met with mixed emotions by parents, officials within the organization and privacy advocates who raisedconcernsabout exposing so many girls, as young as 13, to the potential for cyber-bullying, online predators and other dangers of the Web. Some say the idea is long overdue: How can you teach entrepreneurship to a generationof young women without developing their online skills? But others are worried aboutencouragingso many children -- there are 2.3 million Girls Scouts in the country-- to court friends, coworkers of parents, acquaintances, and other consumers through Web sites that havelittleorganizational supervision.
It's a big step for the Girl Scouts -- and for the Hicks family.Rebecka said she's already excited to sell her waresto relatives who live far away and to allow customers topay with credit cards instead of cash. "I definitely think this will go forward in a positive way," she said.
The risks aren't lost on Hicks' mom. "I have concerns, but I feel as though they've put good measurements in place," said Krista Hicks, who lives in Mechanicsville, Va. Plus, she added, it doesn't do any good to fight the inevitable. "They do live in that world and this gives them more education and chances for thought about what the dangers that are out there."
Some are more hesitant about the push online. The Girl Scouts Council of the Nation's Capital -- the country's largest chapter with 90,000 members in the D.C. area -- said it isn'tparticipating in the "Digital Cookie" program yet, in part due tosafety concerns.
Lidia Soto-Harmon, chief executive of the D.C. Girl Scouts' council, agreedthe girls need to embrace technology, but said safety is still her first concern. The group's troopers will be allowed to set upcredit card payments, but notpersonal Web sites.
"We are known for being a traditional council," Soto-Harmonsaid. "We're making sure, to your point about security issues, that we're protecting the data on the girls, and what the girls are collecting."
The Scouts say that they have put in a number of measures to protect the girls from online predators, and have been working on this program for at least fiveyears. A Girl Scouts spokesman said that only a girl's first name will be part of her custom site -- similar to a seller's page on eBay. Her last name, location and other identifying information won't be listedby default. The organization also made sure that all customer and scout data is encrypted. Girls won't be required to set up Web sites, but those who do will have to take apledge for online safety, plus lessons on issues such as cyberbullying and dealing with strangers online.
But some online safety and security expertssaid not every family willunderstand the risks. Plus,its not easy for parents to monitor everything their kids are doing online.
