Spitzer's infrared vision

By using Spitzer Space Telescope, their measured the size of an asteroid. Astronomers called the asteroid as 2011 MD(found roughly 20feet in size), structure for asteroid contain a lot of empty space. Spitzer's infrared vision helps to sizing up the asteroid.

Michael Momment said "Spitzer can use its heat-sensitive infrared vision to spy asteroids and get better estimates of their sizes". Indicating the object's true size, infrared light is most useful. The size of 2011MD was roughly known, by using visible light it can be observed.

Keeping foods fresher for a long duration in space with misting systems

Even though there are many advancement in technology, keeping foods fresher in space for a long period has been impossible. Research has been going on to keep fresh fruits and vegetables for long-term in space. It has been found that spraying waters over fruits and vegetables keep them fresher for a long period. It’s a fact that if a plant or a food has more solute than the environment surrounding it then to achieve equilibrium state water diffuses into the cell.

Thus by routinely spraying the vegetables with water it keeps up their turgor pressure and keeps them nice and crisp for us to eat.

And this can be achieved by creating a food locker installed with misting systems. A misting system can be used a water sprayer and can help to keep food fresher for a long period.

Based on the above considerations, our research and development team at designed an extraordinary misting product that can be used in the food lockers used in space to keep foods fresher for a longer period. This misting product creates a tiny mist at regular intervals that work as a water sprayer to keep foods and vegetables fresh over a long term.

Infact the mist generated by this specially designed misting product preserves the foods from being getting spoiled.

This may sound ridiculous but in a recent test conducted it has been proved that the foods kept under this product remained fresh for more than three months. Now with this product our astronauts can have fresh and tastier food in space as we have at earth.

Stopping and Stretching

Hello, my name is Saina Ghandchi. I am a member of engineering, operations team and this is your Curiosity Rover update.

Couple of days ago, we performed some atmospheric measurements with our instrument, SAM. Scientists are going through the data at this point and I’m very excited because since Viking mission, we haven’t had any instruments on Mars than can tell what is the composition of the Martian atmosphere.

We also received these color beautiful HiRise images. They show clearly the back shell, the site where the descent stage crashed. And also, very cool, you can clearly see the rover tracks in these images.

Navigator Technology Takes GPS to a New High

GPS navigational devices are as ubiquitous as cell phones, freely used by commercial and government users alike to determine location, time, and velocity. These tools, however, are only as good as the signals they receive. Now, NASA engineers have found a way to improve the reception of those signals.

GPS, which stands for the Global Positioning System, is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense. GPS originally was intended for military uses, but in the 1980s, the government made the system available for civilian use. GPS systems now are available to users worldwide who need accurate positioning, navigation, and timing services.

Thanks to a team of engineers from the NASA Goddard Space Flight Center in Greenbelt, Md., spacecraft operating in weak-signal areas — such as geosynchronous orbits where communications and weather satellites typically operate — will be able to acquire and track the weak GPS signals to determine their locations, much like motorists who use GPS to determine where they are. For their work developing the Navigator GPS receiver, the Goddard team was nominated for the coveted NASA "Invention of the Year" award, a prize reserved for NASA employees who have secured patents for their inventions. An announcement is expected shortly.

Although millions of people rely on GPS receivers today for terrestrial applications, onboard GPS navigation for spaceflight operations has been much more challenging — particularly for spacecraft operating above the GPS constellation, which is about 20,200 kilometers (12,727 miles) above Earth in an area normally referred to as high-Earth orbit. That is because existing GPS receivers could not adequately pick up the GPS signal, which is transmitted toward Earth, not away from it. As a result, spacecraft above the constellation could not reliably use GPS for tracking and navigational purposes, forcing them to use more expensive ground-tracking assets.

Seeing an opportunity to help lower mission costs, the Navigator team, led by Goddard engineer Luke Winternitz, used Research and Development (R&D) funding to develop algorithms and hardware for a prototype spacecraft GPS receiver that would allow spacecraft to acquire and track weak GPS signals at an altitude of 100,000 km (62,137 miles) — well above the GPS constellation, roughly one quarter of the distance to the moon.

"The R&D investment allowed us to develop the weak-signal Navigator GPS receiver and bring it to fruition," Winternitz says. "Proof of the value of this investment lies in the explosion of flight opportunities and commercialization ventures that have followed."

Since its development, the technology has secured flight opportunities on several new missions. Navigator will serve as the primary navigation sensor on NASA’s Global Precipitation Measurement Mission (GPM), which will study global rain and snowfall when it launches in 2013.

It is considered the enabling navigation technology for another Goddard-managed project, the Magnetospheric MultiScale (MMS) mission. The mission is made up of four identically instrumented spacecraft that will fly in formation in a very high-altitude Earth orbit, while measuring the 3-D structure and dynamics of Earth’s protective magnetosphere. The mission will rely on the Navigator GPS receiver’s improved sensitivity to help the satellites maintain their precise orbital position.

The Air Force Research Laboratory (AFRL) at Kirtland Air Force Base, N.M. is planning to use a Navigator engineering test unit in its "Plug-and-Play" spacecraft, an experimental satellite that can be developed and launched within days because it uses components that hook together in a manner similar to how a computer adds drives or printers via a Universal Serial Bus interface.

The Navigator team also has delivered an engineering test unit to the next-generation weather satellite called GOES-R, which the National Oceanic and Atmospheric Administration plans to launch in 2015. The contractor developing the spacecraft may use Navigator's signal-processing design in the spacecraft’s GPS receiver.

Broad Reach Engineering, an aerospace engineering firm that operates offices in Colorado and Arizona, meanwhile, is pursuing a commercial license for the Navigator signal-processing technology. It plans to use the technology to build a GPS unit for a U.S. government program currently under development. The company also plans to use Navigator to develop other products that could be used in potential commercial satellite programs or scientific missions, says Dan Smith, a Broad Reach project manager.

And if those successes weren't enough, Navigator proved its mettle during a first-of-its-kind experiment carried out during STS-125, the Hubble Space Telescope Servicing Mission last year. While astronauts rendezvoused with and grappled the telescope, the experiment used radar measurements of GPS signals that were reflected off the Hubble to provide range estimates during docking and undocking, proving a key relative navigation sensing technology that could potentially be used in a robotic rendezvous with the Hubble in the future.

"No question. The Navigator team has experienced an incredible level of success," says John Carl Adams, an assistant chief of technology for Goddard’s Applied Engineering and Technology Directorate’s mission engineering and systems analysis division. "I attribute their accomplishment to technical know-how, but also to a healthy entrepreneurial spirit. These guys saw a need and developed a solution, which is now driving down mission costs for civilian and military space programs and extending the range of spacecraft GPS sensing to geosynchronous orbits and beyond."

More Advances Planned

The team is now looking to further improve the technology.

Winternitz and his team are developing the next-generation Navigator receiver — one that can acquire the GPS signal even if the spacecraft carrying the receiver is located at lunar distances. Such a capability would reduce mission operational costs because ground controllers could track spacecraft via GPS rather than with expensive ground stations.

"We expect that the evolution of Navigator’s capabilities will open up a host of new applications and funding sources, including exploration and high-altitude science missions," Winternitz says. "Navigator’s selling points will continue to be that it can offer better navigation performance in weak-signal and highly dynamic environments."

Cassini Spots Tiny Celestial satellite, Starts to Point Orbit

NASA's Cassini spacecraft created its nearest strategy to Saturn's little celestial satellite Methone as aspect of a velocity that will take it on a near flyby of another of Saturn's moons, Powerhouse. The Powerhouse flyby will put the spacecraft in an orbit around Saturn that is prepared, or straight, comparative to the aircraft of the globe's equator. The flyby of Methone took position on May 20 at a range of about 1,200 kilometers (1,900 kilometers). It was Cassini's nearest flyby of the 2-mile-wide (3-kilometer-wide) celestial satellite. The best previous Cassini pictures were taken on May 8, 2005, at a range of about 140,000 kilometers (225,000 kilometers), and they hardly settled this item.

Also on May 20, Cassini acquired pictures of Tethys, a bigger Saturnian celestial satellite that is 660 kilometers (1,062 kilometers) across. The spacecraft went by Tethys at a range of about 34,000 kilometers (54,000 kilometers).

Cassini's encounter with Powerhouse, Saturn's biggest celestial satellite, on May 22, is the first of a series of flybys that will put the spacecraft into an prepared orbit. At nearest strategy, Cassini will fly within about 593 kilometers (955 kilometers) of the exterior of the obscure Powerhouse. The flyby will position Cassini's direction around Saturn by about 16 levels out of the tropical aircraft, which is the same aircraft in which Saturn's jewelry and most of its moons live.

Cassini's built in thrusters don't have the capability to position the spacecraft into orbits so prepared. But objective developers have organized trajectories that take benefits of the gravitational power applied by Powerhouse to increase Cassini into prepared orbits. Over the next few several weeks, Cassini will use several flybys of Powerhouse to modify the position of its trend, developing one on top of the other until Cassini is revolving about Saturn at around 62 levels comparative to the tropical aircraft in 2013. Cassini hasn't traveled in orbits this prepared since 2008, when it orbited at an position of 74 levels.

This set of prepared orbits is predicted to offer amazing opinions of the jewelry and posts of Saturn. Further research of Saturn's other moons will have to delay until around 2015, when Cassini profits to an tropical orbit.

"Getting Cassini into these prepared orbits is going to need the same stage of routing precision that the group has provided in previous times, because each of these Powerhouse flybys has to remain right on the cash," said John Mitchell, Cassini system administrator at NASA's Jet Space Clinical, Pasadena, Calif. "However, with nearly eight decades of encounter to depend on, there's no question about their capability to take this off."

Cassini found Methone and two other little moons, Pallene and Anthe, between the orbits of Mimas and Enceladus between 2004 and 2007. The three little moons, known as the Alkyonides group, are included in Saturn's E band, and their materials are applied by ice contaminants via the water jets of water ice, water steam and natural substances via the southern region complete place of Enceladus.

The Cassini-Huygens objective is a supportive venture of NASA, the Western Area Organization and the French language Area Organization. JPL controls the objective for the company's Technological innovation Mission Directorate in Florida. The Florida Institution of Technological innovation in Pasadena controls JPL for NASA.

Sunspot Has Produced M-Class Flares, But No CMEs

Due to current issues on the SOHO spacecraft, the LASCO instrument was not taking data during this event. This instrument is used to develop the near real-time coronal mass ejections alerts. The STEREO beacon data is now coming online and indicates a possible small coronal mass ejection. A preliminary indication of its direction indicates a low likelihood of any geomagnetic storms at Earth.
A particularly large and complex sunspot appeared over the left limb of the sun on Saturday, May 5, beginning its two-week trek across the face of the star in conjunction with the sun's rotation. The sunspot, dubbed Active Region 1476, has so far produced seven M-class flares and numerous C-class flares, including two M-class flares on May 9, 2012 that peaked at 8:32 EDT and 10:08 EDT. These flares were all short-lived and there were no associated coronal mass ejections, so we do not expect any geomagnetic storms at Earth.

NASA Image Gallery Highlights Earth’s Changing Face

In celebration of this year's Earth Day on April 22, NASA's Webby Award-winning Global Climate Change website, , has unveiled a new version of its popular image gallery, "State of Flux." The gallery, which can be found at , presents stunning images, mostly from space, of our ever-changing planet, chronicling changes taking place over time periods ranging from days to centuries.
Each image pair in the continuously updated gallery highlights before-and-after impacts of change, including the destruction wrought by extreme events such as wildfires and floods, the retreat of glaciers caused by climate change, and the expanding footprint of urban areas due to population growth.

The redesigned gallery, which currently features more than 160 comparison views, is now organized and sortable by categories, including ice, human impact, water, land cover and extreme events. A selection of some of the Global Climate Change website team’s favorite images is highlighted in a new "Top Picks" category.

Another new feature is a map view, which places each image into its geographical context. Guests can zoom in to specific locations on the map, or select by region, and see where particular changes are taking place around the globe. They can also share links to each image set and download high-resolution versions of the images.

"Seeing our planet from space gives us a global view that we can't get elsewhere," said Amber Jenkins, editor of the Global Climate Change website, who established the gallery in 2009. "It underscores how fragile and interconnected our planet is, and how it is constantly changing. With this new version of the gallery, we want people to be better able to immerse themselves in the images, and gain that sense of perspective."

Paydirt at 8-Year-Old Mars Rover's 'New Landing Site'

A report in the May 4 edition of the journal Science details discoveries Opportunity made in its first four months at the rim of Endeavour Crater, including key findings reported at a geophysics conference in late 2011.

Opportunity completed its original three-month mission on Mars eight years ago. It reached Endeavour last summer, three years after the rover's science team chose Endeavour as a long-term destination. This crater is about 4 billion years old and 14 miles (22 kilometers) in diameter.

The impact that excavated the crater left a jumble of fused-together rock fragments around the rim. In a chunk brought to the surface by a later, much smaller impact into the rim, Opportunity found evidence that the original impact released heated, underground water that deposited zinc in that rock. Later after the impact, cool water flowed through cracks in the ground near the edge of the crater and deposited veins of the mineral gypsum.

"These bright mineral veins are different from anything seen previously on Mars, and they tell a clear story of water flowing through cracks in the rocks," said Steve Squyres of Cornell University, Ithaca, N.Y. He is the principal investigator for Opportunity and lead author of the new report by 27 researchers. "From landing until just before reaching the Endeavour rim, Opportunity was driving over sandstone made of sulfate grains that had been deposited by water and later blown around by the wind. These gypsum veins tell us about water that flowed through the rocks at this exact spot. It's the strongest evidence for water that we've ever seen with Opportunity."

For the past four months, the solar-powered rover has been working at one outcrop on the Endeavour rim, called Greeley Haven. Reduced daylight during the Martian winter, and accumulated dust on the rover's solar array, have kept energy too low for driving. "The days are now growing longer, and the sun is moving higher in the sky at Endeavour Crater. We expect Opportunity to resume driving in the next two months and continue exploring other parts of the crater's rim," said Mars Exploration Rover Project Manager John Callas of NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Researchers hope to get Opportunity to one of the deposits of clay minerals that have been detected in Endeavour's rim by observations from orbit. These minerals could be evidence of a non-acidic wet phase of the region's environmental history.

"Exploring Endeavour Crater is like having a new landing site," said JPL's Timothy Parker, a co-author of the new report. "That's not just because of the difference in the geology here compared to what we saw during most of the first eight years, but also because there's a whole vista before us inviting much more exploration."

Opportunity and its rover twin, Spirit, completed their three-month prime missions on Mars in April 2004. Both rovers continued for years of bonus, extended missions. Both have made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life. Spirit stopped communicating in 2010.

NASA launched the next-generation Mars rover, car-size Curiosity of the Mars Science Laboratory mission, on Nov. 26 for arrival at Mars' Gale Crater in August 2012.

'Beautiful Earth' Combines Live Music, American Indian Perspectives with NASA Science and Technology

Composer Kenji Williams couples awe-inspiring NASA satellite imagery with innovative violin and electronic melodies in his "Bella Gaia" program. The Visitor Center at NASA's Goddard Space Flight Center in Greenbelt, Md., hosted a live performance of Bella Gaia on April 19 as part of a NASA educational program called "Beautiful Earth."

Beautiful Earth combines Williams's Bella Gaia show with interactive talks by scientists and American Indian educators, and hands-on workshops for students. Williams's performance of Bella Gaia (which translates to "Beautiful Earth)" provides an emotional element to the science education program.

"I would love for people to feel a real and personal connection with the science of the living Earth," Williams said. "Without this emotional connection, stewardship of our resources will be difficult to develop in any long-lasting way. A 'culture of ecology’ is what is needed to create pervasive change, and this is what I would like audiences to feel with their minds and hearts."

NASA's Beautiful Earth showcases Earth's systems and highlights many NASA missions studying Earth. The show on April 19 focused on the water cycle and featured video of American Indians from the Ottawa and Chippewa tribes undertaking a "water walk," a sacred ceremony that celebrates the connections between water and life. The production also included imagery of forest fires in the Amazon and time-lapses of Arctic ice.

Williams created Bella Gaia to inspire people and give them a glimpse into the rare vantage point that astronauts have when they are in space.

"I was inspired by a meeting and conversation with NASA astronaut Mike Fincke several years ago," Williams said. "He told me of his profound transformation the first time he saw the Earth from space, from the International Space Station. I was so inspired by his story that it got me thinking, 'How could I bring this transformative experienced that astronauts commonly have, to those of us who can't go to space?'"

This "transformative experience," which author Frank White called the Overview Effect, represents a change in how some returning astronauts conceptualize Earth, one that overshadows manmade boundaries by a sudden awareness that Earth operates as a borderless, interconnected whole.

In this Beautiful Earth program, Williams played violin over electronic music against a multimedia backdrop of NASA scientific visualizations and views of Earth from space. Interactive talks featured several speakers, including astronomer Jim Rock, of the Native American Dakota tribe, and Thorsten Markus, chief of Goddard's Cryospheric Sciences Lab.
