The Puffin: A Passion for Personal Flight

Meet the Puffin. It's an airplane concept conjured up by the mind of aerospace engineer Mark Moore. The unusual looking, vertical take-off and landing tailsitter is only an idea, but you'd never know that from the attention the Puffin has gotten on the Internet.

Moore came up with the design for the electric powered, 12-foot (3.7 m) long, 14.5-foot (4.4 m) wingspan personal air vehicle as part of the coursework for his doctoral degree. Then Langley's creativity and innovation and revolutionary technical challenges funds paid for much of the research. How the Puffin rocketed from esoteric erudition to web sensation is a classic case study in the power of the viral nature of the web.

"The animation of the Puffin on YouTube has gotten more 648,000 hits in a week," said Moore. "Until the concept was mentioned in the media Jan. 19, the video had only been clicked on a couple of thousand times since it was uploaded to the NASAPAV channel last November."

It all started with an email from a reporter who was pursuing a story on electric aircraft propulsion for "a couple of websites associated with space.com." As the former manager of the former Vehicle System program's Personal Air Vehicle sector. Moore is a nationally recognized expert on that and other small aircraft systems.

The Puffin personal air vehicle conceptMoore not only shared information about electric motor research for airplanes, but also the Puffin design that he and a team from Massachusetts Institute of Technology, the Georgia Institute of Technology, the National Institute of Aerospace (NIA), and M-DOT Aerospace planned to present to an American Helicopter Society conference on aeromechanics, Jan. 20. Combine NASA cachet with an intriguing technology concept, some compelling animation created by Analytical Mechanics Associates graphic designers and quotable quotes from Moore and the story of the Puffin lifted off.

First it appeared on the Scientific American website from the original interview on electric aircraft propulsion. There Moore was quoted as saying the team named the design the Puffin because, "If you've ever seen a puffin on the ground, it looks very awkward, with wings too small to fly, and that's exactly what our vehicle looks like," Moore says. "But it's also apparently called the most environmentally friendly bird, because it hides its poop. So the vehicle is environmentally friendly because it essentially has no emissions. Also, puffins tend to live in solitude, only ever coming together on land to mate, and ours is a one-person vehicle."

The pictures and video of the Puffin helped attract media attention too. It's not everyday that you see a design that's part plane, part helicopter that stands upright on the ground. Its tail splits into four "legs" that serve as landing gear. It lifts off like a helicopter, hovers and then leans forward to fly horizontally with the pilot lying down like in a hang-glider.

Even the technical details were pretty interesting. If ever built the proposed aircraft would be small and very lightweight -- about 300 pounds (136 kg) empty weight plus another 100 pounds (45 kg) of battery and 200 pounds (91 kg) for the pilot or payload. The design would be powered by a total of 60 horsepower through electric motors, which are designed to be able to fail any two powertrain components on either side and still produce the required power to hover. It has a cruising speed of 150 mph (241 kph), but cruises more efficiently at lower speeds The range with current battery technology would be about 50 miles (80 km).

The first web story snowballed until the Puffin garnered worldwide attention, capturing more than 10 news.google.com search pages in less than seven days with stories in media from Japan, Russia, Germany, Hungary, Poland, Italy, Romania, Turkey, Chile, Spain, Guatemala, Greece, Peru, Mexico, Norway, Argentina, Czechoslovakia, China, Korea, and others. A full "Google" search of "NASA Puffin" indicated there were more than 38,000 hits for the combined words. Moore and the NASA Langley News Media Team got inquiries from a New York Times blogger, Germany's biggest Sunday paper, a French men's magazine, ABC News and many more. Even the social media site "Twitter" has been all a-twitter with more than 1,200 tweets about the Puffin in a week.

The Puffin personal air vehicle conceptFor Moore the publicity was an added bonus, but it was the way the work was accomplished that really excited him. "I've been doing conceptual design studies for 25 years, and this is the first time that I have performed a six month conceptual design study that involved such detailed analyses performed right from the onset (that is viscous full Navier Stokes Overflow aero solutions feeding WopWop aeroacoustic analysis, along with MBDyn rotor dynamics, with detailed transition trajectory analysis)," said Moore. "So I think it is a poster child of higher-order methods being able to push themselves far forward to the front stages of design -- to avoid the nasty 'real world' surprises that higher-order analysis can bring at later stages. Getting systems analysis to work in closer collaboration with discipline experts is greatly needed as we progress towards greater multi-disciplinary coupling to solve highly complex problems."

The other thing the engineer says he looks forward to is sharing the technical results of the studies and "the depth of analysis that exists" with other researchers. He'd much rather do that, Moore says, than talk to reporters.

As for the Puffin media frenzy -- it's subsided some, but could start back up later this year when the NIA hopes to fly a remote control one-third size model to validate assumptions made in academic studies, with the specific intent of exploring the transition from hover to forward flight.

Endeavour Lifts Off

Space shuttle Endeavour lights up the night sky as it lifts off from Launch Pad 39A at NASA's Kennedy Space Center in Florida. The primary payload for the STS-130 mission to the International Space Station is the Tranquility node, a pressurized module that will provide additional room for crew members and many of the station's life support and environmental control systems. Attached to one end of Tranquility is a cupola, a unique work area with six windows on its sides and one on top.

The cupola resembles a circular bay window and will provide a vastly improved view of the station's exterior. The multi-directional view will allow the crew to monitor spacewalks and docking operations, as well as provide a spectacular view of Earth and other celestial objects. The module was built in Turin, Italy, by Thales Alenia Space for the European Space Agency.

Launch of NASA’s Shuttle Endeavour Sparks Early Monday Sunrise

Space shuttle Endeavour lit up the predawn sky above Florida's Space Coast on Monday with a 4:14 a.m. EST launch from NASA's Kennedy Space Center. The shuttle's last scheduled night launch began a 13-day flight to the International Space Station and the final year of shuttle operations.

Endeavour's STS-130 mission will include three spacewalks and the delivery of the Tranquility node, the final major U.S. portion of the station. Tranquility will provide additional room for crew members and many of the space station's life support and environmental control systems.

Attached to Tranquility is a cupola with seven windows, which houses a robotic control station. The windows will provide a panoramic view of Earth, celestial objects and visiting spacecraft. After the node and cupola are added, the orbiting laboratory will be approximately 90 percent complete.

Shortly before liftoff, Commander George Zamka said, "Thanks to the great team that got Tranquility, cupola and Endeavour to this point. And thanks also to the team that got us ready to bring Node 3 and cupola to life. We'll see you in a couple of weeks. It's time to go fly."

Zamka is joined on the flight by Pilot Terry Virts and Mission Specialists Kathryn Hire, Stephen Robinson, Nicholas Patrick and Robert Behnken. Virts is making his first trip to space.

Endeavour's first landing opportunity at Kennedy is scheduled for Saturday, Feb. 20, at 10:01 p.m. The STS-130 mission will be Endeavour's 24th flight and the 32nd shuttle mission dedicated to station assembly and maintenance.

NASA Managers Say "Super Shuttle" Sunday Launch a "Go"

Officials meeting at NASA's Kennedy Space Center in Florida reviewed space shuttle Endeavour's readiness for flight at the L-2 prelaunch meeting. They unanimously decided to move forward with the STS-130 mission countdown to launch on Sunday at 4:39 a.m. EST.

Mike Moses, shuttle launch integration manager, said, "We're really looking forward to this launch carrying up node 3 and the cupola.

"From the shuttle program perspective, looking at our launch readiness, we're in really good shape. We had a fantastic review this morning," continued Moses, "Unanimous poll, everyone's pressing forward to go for launch."

Bernardo Patti, ESA's International Space Station program manager, said how happy and proud he is to see the last two European elements ready for the space station. He also commented on the great support and cooperation between the space agencies and how rewarding the process has been.

Mike Leinbach, shuttle launch director, reported his team is not tracking any technical issues and everything is on track for the rotating service structure rollback at 8 a.m. Saturday and loading of the external fuel tank with propellants around 7:15 p.m.

"The team is energized and excited about the countdown... looking forward to getting Endeavour off the ground Sunday morning," said Leinbach.

Kathy Winters, shuttle weather officer, said the forecast has improved and there's only a 20 percent chance weather would be an issue at launch time. Although it may be a little chilly and breezy, no constraints should be violated. The forecast at the transoceanic abort landing sites in Spain and France also looks favorable.

Saturday at 7 p.m., NASA TV will air the fueling of Endeavour's external tank at http://www.nasa.gov/ntv. At 11:30 p.m., live launch coverage will kick off on NASA TV.

You also can follow Endeavour's exciting countdown to launch with NASA's Launch Blog from inside Kennedy's Firing Room 3 beginning at 11:30 p.m. and continuing through main engine cutoff -- when Endeavour reaches orbit on its two-day race to the station.

Space Station Primed for New Era of Scientific Discoveries

NASA and its international partners are looking forward to unprecedented scientific opportunities aboard the International Space Station, or ISS. With station assembly nearing completion, the ISS Partnership is looking forward to using the station to its fullest capacity. The U.S. administration's fiscal year 2011 budget proposal calls for continuing station operations to at least 2020, which will create new opportunities for advancing microgravity science research.

"This is a really exciting week for the space station and for the scientists that want to use these laboratories," said Julie Robinson, program scientist for the station at NASA's Johnson Space Center in Houston. "We've already had some important findings on station during its construction. With this strong support for continued space station lifetime to 2020 or beyond, we will have amazing discoveries from the science and technology research that can be accomplished."

NASA senior managers from the space station program and counterparts at Russia's Roscosmos, the European Space Agency, Canadian Space Agency and Japan's Ministry of Education, Culture, Sports, Science and Technology met to discuss the implications of continuing station operations and utilization and recently issued a joint statement about the station's future.

They noted, "ISS continuation could bring great benefit to all partners and humankind by demonstrating significant and sustained return on the partnership's investment in the ISS program, primarily through the enhanced research and usage opportunities."

The entire statement is available at:

http://www.nasa.gov/pdf/423071main_mcb_joint_stmt_020110.pdf

The ISS Partnership is scheduled to meet again at the Heads of Agency level on March 11 in Tokyo to further discuss partner efforts to undertake their own decisions for space station extension and the opportunity it will provide to use this unique platform for scientific, technological, diplomatic and educational purposes.

The continued use of the station will open the window for more studies that can only be done in the unique environment of space. Specifically, scientists can discover how cells reproduce and differentiate in microgravity with applications to areas such as tissue generation and wound repair. Also, there are opportunities for more human physiology research to learn about systems such as heart, muscle and bone, which can benefit space explorers and ill or injured patients.

Studies of fluid physics that benefit from lack of buoyancy in microgravity will provide new understanding of soft matter, supercritical fluids and two phase flow. Technology tests will advance areas such as robotics, life support and spacecraft servicing.

Station construction began in Dec. 1998 and will be completed during 2010. Once complete, the station will transition to a new "full usage" phase, where continuous scientific research will be conducted aboard the multinational orbiting laboratory.

During the past decade, scientific research accomplishments made aboard the station included advances in the fight against food poisoning and new methods for delivering medicine to cancer cells. Studies of salmonella bacteria identified the controlling gene responsible for its increased virulence in microgravity, and a commercial company has used changes in virulence of microbes to screen for candidate vaccines.

Results of an early station experiment led to improvements in a method for delivering drugs to targets in the human body. The research led the way for better methods of micro-encapsulation, a process of forming miniature, liquid-filled balloons the size of blood cells that can deliver treatment directly to cancer cells.

NASA has a new Web feature that provides examples of space station research dividends including cancer treatment, food poisoning vaccine development, air purification, remote ultrasound tests and many more. For more information about station science payoffs, visit:

NASA, GM Take Giant Leap in Robotic Technology

NASA and General Motors have come together to develop the next generation dexterous humanoid robotRobonaut is evolving.

NASA and General Motors are working together to accelerate development of the next generation of robots and related technologies for use in the automotive and aerospace industries.

Engineers and scientists from NASA and GM worked together through a Space Act Agreement at the agency's Johnson Space Center in Houston to build a new humanoid robot capable of working side by side with people. Using leading edge control, sensor and vision technologies, future robots could assist astronauts during hazardous space missions and help GM build safer cars and plants.

The two organizations, with the help of engineers from Oceaneering Space Systems of Houston, developed and built the next iteration of Robonaut. Robonaut 2, or R2, is a faster, more dexterous and more technologically advanced robot. This new generation robot can use its hands to do work beyond the scope of prior humanoid machines. R2 can work safely alongside people, a necessity both on Earth and in space.

"This cutting-edge robotics technology holds great promise, not only for NASA, but also for the nation," said Doug Cooke, associate administrator for the Exploration Systems Mission Directorate at NASA Headquarters in Washington. "I'm very excited about the new opportunities for human and robotic exploration these versatile robots provide across a wide range of applications."

"For GM, this is about safer cars and safer plants," said Alan Taub, GM's vice president for global research and development. "When it comes to future vehicles, the advancements in controls, sensors and vision technology can be used to develop advanced vehicle safety systems. The partnership's vision is to explore advanced robots working together in harmony with people, building better, higher quality vehicles in a safer, more competitive manufacturing environment."

The idea of using dexterous, human-like robots capable of using their hands to do intricate work is not new to the aerospace industry. The original Robonaut, a humanoid robot designed for space travel, was built by the software, robotics and simulation division at Johnson in a collaborative effort with the Defense Advanced Research Project Agency 10 years ago. During the past decade, NASA gained significant expertise in building robotic technologies for space applications. These capabilities will help NASA launch a bold new era of space exploration.

Robonaut2 – or R2 for short – is the next generation dexterous robot, developed through a Space Act Agreement by NASA and General Motors"Our challenge today is to build machines that can help humans work and explore in space," said Mike Coats, Johnson's center director. "Working side by side with humans, or going where the risks are too great for people, machines like Robonaut will expand our capability for construction and discovery."

NASA and GM have a long, rich history of partnering on key technologies, starting in the 1960s with the development of the navigation systems for the Apollo missions. GM also played a vital role in the development of the Lunar Rover Vehicle, the first vehicle to be used on the moon.

New Hubble Maps of Pluto Show Surface Changes

Hubble images of Pluto
NASA today released the most detailed set of images ever taken of the distant dwarf planet Pluto. The images taken by NASA's Hubble Space Telescope show an icy and dark molasses-colored, mottled world that is undergoing seasonal changes in its surface color and brightness. Pluto has become significantly redder, while its illuminated northern hemisphere is getting brighter. These changes are most likely consequences of surface ices sublimating on the sunlit pole and then refreezing on the other pole as the dwarf planet heads into the next phase of its 248-year-long seasonal cycle. The dramatic change in color apparently took place in a two-year period, from 2000 to 2002.

The Hubble images will remain our sharpest view of Pluto until NASA's New Horizons probe is within six months of its Pluto flyby. The Hubble pictures are proving invaluable for picking out the planet's most interesting-looking hemisphere for the New Horizons spacecraft to swoop over when it flies by Pluto in 2015.

Though Pluto is arguably one of the public's favorite planetary objects, it is also the hardest of which to get a detailed portrait because the world is small and very far away. Hubble resolves surface variations a few hundred miles across, which are too coarse for understanding surface geology. But in terms of surface color and brightness Hubble reveals a complex-looking and variegated world with white, dark-orange and charcoal-black terrain. The overall color is believed to be a result of ultraviolet radiation from the distant sun breaking up methane that is present on Pluto's surface, leaving behind a dark and red carbon-rich residue.

When Hubble pictures taken in 1994 are compared with a new set of images taken in 2002 to 2003, astronomers see evidence that the northern polar region has gotten brighter, while the southern hemisphere has gotten darker. These changes hint at very complex processes affecting the visible surface, and the new data will be used in continued research.

Pluto as seen by ESA's Faint Object Camera (top) and Hubble's Advanced Camera for Surveys
The images are allowing planetary astronomers to better interpret more than three decades of Pluto observations from other telescopes, says principal investigator Marc Buie of the Southwest Research Institute in Boulder, Colo. "The Hubble observations are the key to tying together these other diverse constraints on Pluto and showing how it all makes sense by providing a context based on weather and seasonal changes, which opens other new lines of investigation."

The Hubble pictures underscore that Pluto is not simply a ball of ice and rock but a dynamic world that undergoes dramatic atmospheric changes. These are driven by seasonal changes that are as much propelled by the planet's 248-year elliptical orbit as its axial tilt, unlike Earth where the tilt alone drives seasons. The seasons are very asymmetric because of Pluto's elliptical orbit. Spring transitions to polar summer quickly in the northern hemisphere because Pluto is moving faster along its orbit when it is closer to the sun.

Ground-based observations, taken in 1988 and 2002, show that the mass of the atmosphere doubled over that time. This may be due to warming and sublimating nitrogen ice. The new Hubble images from 2002 to 2003 are giving astronomers essential clues about how the seasons on Pluto work and about the fate of its atmosphere.

The images, taken by the Advanced Camera for Surveys, are invaluable to planning the details of the New Horizons flyby in 2015. New Horizons will pass by Pluto so quickly that only one hemisphere will be photographed in the highest possible detail. Particularly noticeable in the Hubble image is a bright spot that has been independently noted to be unusually rich in carbon monoxide frost. It is a prime target for New Horizons. "Everybody is puzzled by this feature," says Buie. New Horizons will get an excellent look at the boundary between this bright feature and a nearby region covered in pitch-black surface material.

"The Hubble images will also help New Horizons scientists better calculate the exposure time for each Pluto snapshot, which is important for taking the most detailed pictures possible," says Buie. With no chance for re-exposures, accurate models for the surface of Pluto are essential in preventing pictures that are either under- or overexposed.

The Hubble images are a few pixels wide. But through a technique called dithering, multiple, slightly offset pictures can be combined through computer-image processing to synthesize a higher-resolution view than could be seen in a single exposure. "This has taken four years and 20 computers operating continuously and simultaneously to accomplish," says Buie, who developed special algorithms to sharpen the Hubble data.

The Hubble research results appear in the March 2010 issue of the Astronomical Journal. Buie's science team members are William Grundy of Lowell Observatory in Flagstaff, Ariz., and Eliot Young, Leslie Young, and Alan Stern of Southwest Research Institute in Boulder, Colo.

Buie plans to use Hubble's new Wide Field Camera 3 to make further Pluto observations prior to the arrival of New Horizons.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency. NASA's Goddard Space Flight Center manages the telescope. The Space Telescope Science Institute conducts Hubble science operations. The institute is operated for NASA by the Association of Universities for Research in Astronomy, Inc. in Washington, D.C.

GOES-P All Fueled Up

a solid rocket booster for the Delta IV rocket, slated to launch NASA's GOES-P satellite as it is lowered toward the base of the rocketThe GOES spacecraft continues its processing at the Astrotech Facility in Titusville, Fla. and fuel was loaded into the GOES-P spacecraft on Saturday, January 30. The fuel will keep GOES-P in orbit for about 14 years.

Just as you wouldn't want your car's gas tank to leak, engineers don't want a satellite to leak fuel. So, a team of engineers performed propulsion system pressurization and leak checks before fueling GOES-P. Those preparations were completed on January 22.

The GOES-P spacecraft was moved to the fueling stand and the team began fueling the spacecraft. The oxidizer was successfully loaded on January 28. Like a fire needs oxygen to burn, the spacecraft fuel needs the oxidizer to ignite in space, where there is no air. . The fuel was successfully loaded on January 30.

After carefully lifting and moving the fueled spacecraft, the team successfully mounted GOES P on top of the Delta IV Payload Attach Fitting (PAF). This was completed on February 1. The PAF is a conical shape structure that the spacecraft mounts onto inside the launch vehicle. The spacecraft rides on the PAF until it separates at approximately 22 thousand miles above the Earth's surface.

The launch vehicle continues processing on stand and the United Launch Alliance (ULA) is working off the technical issues that remain. The team is working towards a March 1 launch date.

GOES-P is the latest Geostationary Operational Environmental Satellite developed by NASA for the National Oceanic and Atmospheric Administration, or NOAA. The Delta IV rocket will be launched by United Launch Alliance for Boeing Launch Services under an FAA commercial license. Launch is targeted for no earlier than March 1.

Little Galaxy With a Tail

 Little Galaxy With a Tail

This infrared portrait of the Small Magellanic Cloud, taken by NASA's Spitzer Space Telescope, reveals stars and dust in this galaxy as never seen before.

The image shows the main body of the Small Magellanic Cloud, which is comprised of the "bar" and "wing" on the left and the "tail" extending to the right. The bar contains both old stars (in blue) and young stars lighting up their natal dust (green/red). The wing mainly contains young stars. The tail contains only gas, dust and newly formed stars. Spitzer data has confirmed that the tail region was recently torn off the main body of the galaxy. Two of the tail clusters, which are still embedded in their birth clouds, can be seen as red dots.

The data in this image are being used by astronomers to study the lifecycle of dust in the entire galaxy: from the formation in stellar atmospheres, to the reservoir containing the present day interstellar medium, and the dust consumed in forming new stars. The dust being formed in old, evolved stars (blue stars with a red tinge) is measured using mid-infrared wavelengths. The present day interstellar dust is weighed by measuring the intensity and color of emission at longer infrared wavelengths. The rate at which the raw material is being consumed is determined by studying ionized gas regions and the younger stars (yellow/red extended regions). The Small Magellanic Cloud, and its companion galaxy the Large Magellanic Cloud, are the two galaxies where this type of study is possible.

NASA Invites Public To Tweet Their Way Into Space Next Week

The Twitterverse and universe will converge during space shuttle Endeavour's upcoming mission to the International Space Station. NASA is inviting the public to send questions for the astronauts via Twitter and have them answered live from space.

Astronaut Mike Massimino will be accepting questions for the crew from the public via his Twitter account until Thursday, Feb. 11. Massimino will be a shuttle Capcom, or spacecraft communicator, at NASA's Mission Control in Houston during Endeavour's flight, scheduled for launch Feb. 7.

At 2:24 a.m. CST on Feb. 11, Massimino will host an interactive event with the crew from his console in Mission Control. He will ask the astronauts as many submitted and live questions as practical during the 20-minute event. The shuttle will be docked to the station during the live question and answer session. The event with Endeavour's crew will be broadcast live on the Web and NASA Television.

The public is invited to start tweeting questions for Endeavour's crew today to Massimino's Twitter account, @astro_Mike, or add the hashtag #askastro to their tweets.

Endeavour's 13-day STS-130 mission will include three spacewalks and the delivery of the Tranquility node, the final module of the U.S. portion of the station. Tranquility will provide additional room for crew members and many of the space station's life support and environmental control systems.

Attached to Tranquility is a cupola, which houses a robotic control station and has seven windows. The windows will provide a panoramic view of Earth, celestial objects and visiting spacecraft. After the node and cupola are added, the orbiting laboratory will be approximately 90 percent complete.

The time and day of the Twitter session are subject to change due to mission priorities. Updates to the NASA TV event schedule are available online at:

Pluto’s White, Dark-Orange and Charcoal-Black Terrain Captured by NASA’s Hubble

NASA has released the most detailed and dramatic images ever taken of the distant dwarf planet Pluto. The images from NASA's Hubble Space Telescope show an icy, mottled, dark molasses-colored world undergoing seasonal surface color and brightness changes.

Pluto has become significantly redder, while its illuminated northern hemisphere is getting brighter. These changes are most likely consequences of surface ice melting on the sunlit pole and then refreezing on the other pole, as the dwarf planet heads into the next phase of its 248-year-long seasonal cycle. Analysis shows the dramatic change in color took place from 2000 to 2002.

The Hubble pictures confirm Pluto is a dynamic world that undergoes dramatic atmospheric changes not simply a ball of ice and rock. These dynamic seasonal changes are as much propelled by the planet's 248-year elliptical orbit as by its axial tilt. Pluto is unlike Earth, where the planet's tilt alone drives seasons. Pluto's seasons are asymmetric because of its elliptical orbit. Spring transitions to polar summer quickly in the northern hemisphere, because Pluto is moving faster along its orbit when it is closer to the sun.

Ground-based observations, taken in 1988 and 2002 show the mass of the atmosphere doubled during that time. This may be because of warming and melting nitrogen ice. The new Hubble images are giving astronomers essential clues about the seasons on Pluto and the fate of its atmosphere.

When the Hubble pictures taken in 1994 are compared to those of 2002 and 2003, astronomers see evidence that the northern polar region has gotten brighter, while the southern hemisphere darkened. These changes hint at very complex processes affecting the visible surface.

The images will help planetary astronomers interpret more than three decades of Pluto observations from other telescopes.

"The Hubble observations are the key to tying together these other diverse constraints on Pluto and showing how it all makes sense by providing a context based on weather and seasonal changes, which opens other new lines of investigation," says principal investigator Marc Buie of the Southwest Research Institute in Boulder, Colo.

These Hubble images, taken by the Advanced Camera for Surveys, will remain the sharpest view of Pluto until NASA's New Horizons probe is within six months of its flyby during 2015. The Hubble images are invaluable for picking the planet's most interesting hemisphere for imaging by the New Horizons probe.

New Horizons will pass by Pluto so quickly that only one hemisphere will be photographed in detail. Particularly noticeable in the Hubble images is a bright spot that has been independently noted to be unusually rich in carbon monoxide frost. It is a prime target for New Horizons. "Everybody is puzzled by this feature," Buie said. New Horizons will get an excellent look at the boundary between this bright feature and a nearby region covered in pitch-black surface material.

"The Hubble images also will help New Horizons scientists better calculate the exposure time for each Pluto snapshot which is important for taking the most detailed pictures possible," Buie said. With no chance for re-exposures, accurate models for the surface of Pluto are essential for properly exposed images.

The Hubble images surface variations a few hundred miles across that are too coarse for understanding surface geology. But in terms of surface color and brightness, Hubble reveals a complex-looking world with white, dark-orange and charcoal-black terrain. The overall color is believed to be a result of ultraviolet radiation from the distant sun breaking up methane present on Pluto's surface, leaving behind a dark and red-carbon-rich residue.

The Hubble images are a few pixels wide. Through a technique called dithering, multiple, slightly offset pictures are combined through computer-image processing to synthesize a higher-resolution view than can be seen in a single exposure.

"This has taken four years and 20 computers operating continuously and simultaneously to accomplish," Buie said. Buie developed the special algorithms to sharpen the Hubble data. He plans to use Hubble's new Wide Field Camera 3 to make additional observations prior to the arrival of New Horizons.

NASA Extends Cassini’s Tour of Saturn, Continuing International Cooperation for World Class Science

Saturn equinox 2009
Of the countless equinoxes Saturn has seen since the birth of the solar system, this one, captured here in a mosaic of light and dark, is the first witnessed up close by an emissary from Earth ... none other than our faithful robotic explorer, Cassini. › Full image and caption
NASA will extend the international Cassini-Huygens mission to explore Saturn and its moons to 2017. The agency's fiscal year 2011 budget provides a $60 million per year extension for continued study of the ringed planet.

"This is a mission that never stops providing us surprising scientific results and showing us eye popping new vistas," said Jim Green, director of NASA's planetary science division at NASA Headquarters in Washington. "The historic traveler's stunning discoveries and images have revolutionized our knowledge of Saturn and its moons."

Cassini launched in October 1997 with the European Space Agency's Huygens probe. The spacecraft arrived at Saturn in 2004. The probe was equipped with six instruments to study Titan, Saturn's largest moon. Cassini's 12 instruments have returned a daily stream of data from Saturn's system for nearly six years. The project was scheduled to end in 2008, but the mission received a 27-month extension to Sept. 2010.

"The extension presents a unique opportunity to follow seasonal changes of an outer planet system all the way from its winter to its summer," said Bob Pappalardo, Cassini project scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "Some of Cassini's most exciting discoveries still lie ahead."

This second extension, called the Cassini Solstice Mission, enables scientists to study seasonal and other long-term weather changes on the planet and its moons. Cassini arrived just after Saturn's northern winter solstice, and this extension continues until a few months past northern summer solstice in May 2017. The northern summer solstice marks the beginning of summer in the northern hemisphere and winter in the southern hemisphere.

A complete seasonal period on Saturn has never been studied at this level of detail. The Solstice mission schedule calls for an additional 155 orbits around the planet, 54 flybys of Titan and 11 flybys of the icy moon Enceladus.

The mission extension also will allow scientists to continue observations of Saturn's rings and the magnetic bubble around the planet known as the magnetosphere. The spacecraft will make repeated dives between Saturn and its rings to obtain in depth knowledge of the gas giant. During these dives, the spacecraft will study the internal structure of Saturn, its magnetic fluctuations and ring mass.

The mission will be evaluated periodically to ensure the spacecraft has the ability to achieve new science objectives for the entire extension.

"The spacecraft is doing remarkably well, even as we endure the expected effects of age after logging 2.6 billion miles on its odometer," said Bob Mitchell, Cassini program manager at JPL. "This extension is important because there is so much still to be learned at Saturn. The planet is full of secrets, and it doesn't give them up easily."

Cassini's travel scrapbook includes more than 210,000 images; information gathered during more than 125 revolutions around Saturn; 67 flybys of Titan and eight close flybys of Enceladus. Cassini has revealed unexpected details in the planet's signature rings, and observations of Titan have given scientists a glimpse of what Earth might have been like before life evolved.

Scientists hope to learn answers to many questions that have developed during the course of the mission, including why Saturn seems to have an inconsistent rotation rate and how a probable subsurface ocean feeds the Enceladus' jets.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. JPL manages the project for NASA's Science Mission Directorate in Washington. The Cassini orbiter was designed, developed and assembled at JPL.

A Little Telescope Goes a Long Way

NASA astronomers have successfully demonstrated that a David of a telescope can tackle Goliath-size questions in the quest to study Earth-like planets around other stars. Their work, reported today in the journal Nature, provides a new tool for ground-based observatories, promising to accelerate by years the search for prebiotic, or life-related, molecules on planets orbiting stars beyond our solar system.

The scientists reported on a new technique used with a relatively small Earth-based telescope to identify an organic molecule in the atmosphere of a Jupiter-size planet nearly 63 light-years away. The measurement revealed details of the exoplanet's atmospheric composition and conditions, an unprecedented achievement from an Earth-based observatory.

The surprising new finding comes from a venerable 30-year-old, 3-meter-diameter (10-foot) telescope that ranks 40th among ground-based telescopes - NASA's Infrared Telescope Facility atop Mauna Kea, Hawaii.

The new technique promises to further speed the work of studying planet atmospheres by enabling studies from the ground that were previously possible only through a few very high-performance space telescopes. "Given favorable observing conditions, this work suggests we may be able to detect organic molecules in the atmospheres of terrestrial planets with existing instruments," said lead author Mark Swain, an astronomer at NASA's Jet Propulsion Laboratory, Pasadena, Calif. This can allow fast and economical advances in focused studies of exoplanet atmospheres, accelerating our understanding of the growing stable of exoplanets.

"The fact that we have used a relatively small, ground-based telescope is exciting because it implies that the largest telescopes on the ground, using this technique, may be able to characterize terrestrial exoplanet targets," Swain said.

This artist concept shows the planetary system called HD 189733, located 63 light-years away in the constellation Vulpecula

Currently, more than 400 exoplanets are known. Most are gaseous like Jupiter, but some "super-Earths" are thought to be large terrestrial, or rocky, worlds. A true Earth-like planet, with the same size as our planet and distance from its star, has yet to be discovered. NASA's Kepler mission is searching from space now, and is expected to find several of these earthly worlds by the end of its three-and-a-half-year prime mission.

On Aug. 11, 2007, Swain and his team turned the infrared telescope to the hot, Jupiter-size planet HD 189733b in the constellation Vulpecula. Every 2.2 days, the planet orbits a K-type main sequence star slightly cooler and smaller than our sun. HD189733b had already yielded breakthrough advances in exoplanet science, including detections of water vapor, methane and carbon dioxide, using space telescopes. Using the new technique, the astronomers successfully detected carbon dioxide and methane in the atmosphere of HD 189733b with a spectrograph, which splits light into its components to reveal the distinctive spectral signatures of different chemicals. Their key work was development of a novel calibration method to remove systematic observation errors caused by the variability of Earth's atmosphere and instability due to the movement of the telescope system as it tracks its target.

"As a consequence of this work, we now have the exciting prospect that other suitably equipped yet relatively small ground-based telescopes should be capable of characterizing exoplanets," said John Rayner, the NASA Infrared Telescope Facility support scientist who built the SpeX spectrograph used for these measurements. "On some days we can't even see the sun with the telescope, and the fact that on other days we can now obtain a spectrum of an exoplanet 63 light-years away is astonishing."

This chart explains how astronomers measure the signatures of chemicals in the atmospheres of planets that orbit other stars, called exoplanets

In the course of their observations, the team found unexpected bright infrared emission from methane that stands out on the day side of HD189733b, indicating some kind of activity in the planet's atmosphere. Swain said this puzzling feature could be related to the effect of ultraviolet radiation from the planet's parent star hitting the planet's upper atmosphere, but more detailed study is needed. "This feature indicates the surprises that await us as we study exoplanet atmospheres," he added.

"An immediate goal for using this technique is to more fully characterize the atmosphere of this and other exoplanets, including detection of organic and possibly prebiotic molecules" like those that preceded the evolution of life on Earth, said Swain. "We're ready to undertake that task." Some early targets will be the super-Earths. Used in synergy with observations from NASA's Hubble, Spitzer and the future James Webb Space Telescope, the new technique "will give us an absolutely brilliant way to characterize super-Earths," Swain said.

Crossfield of UCLA; Azam Thatte of the Georgia Institute of Technology, Atlanta; Jeroen Bouwman, Cristina Afonso and Thomas Henning of Max-Planck Institute for Astronomy, Heidelberg, Germany; and Daniel Angerhausen of the German SOFIA Institute, Stuttgart, Germany.

The work was carried out with funding from NASA's Office of Space Science in Washington, D.C. The NASA Infrared Telescope Facility is managed by the University of Hawaii's Institute for Astronomy. JPL is managed by the California Institute of Technology for NASA.

Out-of-This-World Super Bowl Coin Lands in Ohio

This medallion, which was flown in space aboard space shuttle Atlantis, will be used for the official coin toss prior to the kickoff of Super Bowl XLIVAfter traveling more than four million miles, and making 171 orbits around Earth on board space shuttle Atlantis, the Super Bowl XLIV opening-toss coin took a slight detour to the Pro Football Hall of Fame Museum in Canton, Ohio, on Jan. 27, before heading to the Super Bowl.

The coin was flown last November on STS-129 by crew members Commander Charlie Hobaugh, Pilot Barry Wilmore, and Mission Specialists Leland Melvin, Randy Bresnik, Mike Foreman and Bobby Satcher.

The astronauts stopped by the museum to return the silver-minted coin, as well as a few other space-flown memorabilia, including a football inscribed with the name of every member of the Hall of Fame. They also returned flown jerseys from the Detroit Lions and the Dallas Cowboys, the two teams Melvin played for in his short stint in the NFL.

The STS-129 crew presents a specially minted silver medallion to National Football League officials at the Pro Football Hall of Fame in Canton, OhioAfter stopping at the Hall of Fame, the coin will journey to Sun Life Stadium in Miami Gardens, Fla., to be the one of the stars of the Super Bowl XLIV pre-game coin toss on Feb. 7.
