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 mistingsystems.net 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.

NASA Group to Analyze New Vehicle-Descent Technologies

NASA technologists will get a opportunity next summer time to experience the good old days when Organization technical engineers would connect space-age devices to rockets just to see if the gadgets proved helpful.

In what will be the first of four high-altitude enhance routes to begin in the summertime season of 2013, technologists at NASA's Jet Space Clinical (JPL) in Pasadena, Calif., and Wallops Journey Ability in Wallops Isle, Va., are planning to evaluate new deceleration gadgets that could substitute present nice technological innovation for getting ever-larger payloads at higher levels on Mars.

NASA is using a sequence of explode snowmobile assessments at the U.S. Naval Air Weaponry Place at Chinese suppliers Pond, Calif., in planning for full-up assessments of the Low-Density Supersonic Decelerator Venture, or LDSD. The project is examining water and parachute decelerators to slowly spacecraft prior to getting and allow NASA to enhance arrived payload public, enhance getting precision and enhance the elevation of secure landing-sites.

NASA hasn't examined deceleration technological innovation supersonically since 1972 when it performed four high-altitude assessments of a supersonic parachute used during the Viking program. "We’ve been trapped with that style ever since," said Level Adler, NASA’s Low-Density Supersonic Decelerator (LDSD) program lead. NASA will use the same technological innovation again this year when it provides the Fascination rover to Mars.

However, planetary landers of the next day will require much bigger move gadgets than any now in use. "What we need is new technological innovation to slowly bigger, bulkier landers from the supersonic connections of environmental use of subsonic ground-approach connections," Adler said.

The LDSD program is targeted at providing NASA a new and enhanced ability. Financed by NASA’s Area Technology Program, the JPL-led team programs to perform full-scale, stratospheric assessments of three possibly cutting-edge technological innovation. The aim is to increase their technology-readiness levels to about six, which means they could be used in a plane project, perhaps as early as 2018.

The first two are supersonic water decelerators, large stress boats that fill around an access automobile and slowly it from Mach 3.5 or quicker to about Mach 2. One of these water gadgets actions nearly 20 toes across (six meters), the other nearly 26 toes (eight meters). The third technological innovation is a 110-foot (33.5-meter) parachute to further slowly the access automobile from Mach 2 to subsonic connections needed for a secure getting. All three would be the biggest gadgets of their kind ever traveled at connections several times greater than the rate of audio.

The style involves the group to connect the test automobile outfitted with the decelerator and parachute to a Wallops-provided high-altitude enhance. Once the enhance gets to an elevation of about 22 kilometers (36 kilometers) above Global exterior, the explode would flame its applications and bring check automobile to Martian environmental densities at an elevation of 31 kilometers (50 kilometers) at Mach 4. There, check automobile would set up the supersonic decelerator, followed by the parachute.




Perfect Wedding of Capabilities

The project harnesses the strong points of both companies, said Scott Schaire, Wallops LDSD performing project administrator. While NASA JPL and its companies are creating check automobile, decelerators, and parachute, NASA Wallops is accountable for enhance functions, enhance instrumentation, and other functions associated with enhance releases.

One considerable NASA Wallops-provided technological innovation is an entirely new enhance release program — an attempt Schaire's team started particularly for the supersonic assessments. With this new program, check automobile will be revoked from a straight, 80-foot structure. Its job is avoiding check automobile from reaching the earth as the enhance starts to increase off. A customized equipment that appears like a farm-irrigation program will help specialists lay out the enhance and a new reel automobile will hold the enhance until release.

NASA Spacecraft Detects Changes in Martian Sand Dunes

NASA's Mars Reconnaissance Orbiter has revealed that movement in sand dune fields on the Red Planet occurs on a surprisingly large scale, about the same as in dune fields on Earth.

This is unexpected because Mars has a much thinner atmosphere than Earth, is only about one percent as dense, and its high-speed winds are less frequent and weaker than Earth's.

For years, researchers debated whether sand dunes observed on Mars were mostly fossil features related to past climate, rather than currently active. In the past two years, researchers using images from Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE) camera have detected and reported sand movement.

Now, scientists using HiRISE images have determined that entire dunes as thick as 200 feet (61 meters) are moving as coherent units across the Martian landscape. The study was published online today by the journal Nature.

"This exciting discovery will inform scientists trying to better understand the changing surface conditions of Mars on a more global scale," said Doug McCuistion, director, NASA's Mars Exploration Program, Washington. "This improved understanding of surface dynamics will provide vital information in planning future robotic and human Mars exploration missions."

Researchers analyzed before-and-after images using a new software tool developed at the California Institute of Technology (Caltech) in Pasadena, Calif. The tool measured changes in the position of sand ripples, revealing the ripples move faster the higher up they are on a dune.

The study examined images taken in 2007 and 2010 of the Nili Patera sand dune field located near the Martian equator. By correlating the ripples' movement to their position on the dune, the analysis determined the entire dunes are moving. This allows researchers to estimate the volume, or flux, of moving sand.

"We chose Nili Patera because we knew there was sand motion going on there, and we could quantify it," said Nathan Bridges, a planetary scientist at Johns Hopkins University Applied Physics Laboratory in Laurel, Md., and lead author of the Nature paper. "The Nili dunes also are similar to dunes in places like Antarctica and to other locations on Mars."

The study adds important information about the pace at which blowing sand could be actively eroding rocks on Mars. Using the new information about the volume of sand that is moving, scientists estimate rocks in Nili Patera would be worn away at about the same pace as rocks near sand dunes in Antarctica, where similar sand fluxes occur.

"Our new data shows wind activity is indeed a major agent of evolution of the landscape on Mars," said Jean-Philippe Avouac, Caltech team leader. "This is important because it tells us something about the current state of Mars and how the planet is working today, geologically."

NASA to Fly Deep Space Atomic Clock to Improve Navigation Technology


When people think of space technologies, many think of high-tech solar panels, complex and powerful propulsion systems or sophisticated, electronic guidance systems. Another critical piece of spaceflight technology, however, is an ultra stable, highly accurate device for timing - essential to NASA's success on deep-space exploration missions.

NASA is preparing to fly a Deep Space Atomic Clock, or DSAC, demonstration that will revolutionize the way we conduct deep-space navigation by enabling a spacecraft to calculate its own timing and navigation data in real time. This one-way navigation technology would improve upon the current two-way system in which information is sent to Earth, requiring a ground team to calculate timing and navigation and then transmitting it back to the spacecraft. A real-time, on-board navigation capability is key to improving NASA’s capabilities for executing time critical events, such as a planetary landing or planetary "fly-by," when signal delays are too great for the ground to interact with the spacecraft during the event.

"Adopting DSAC on future NASA missions will increase navigation and radio science data quantity by two to three times, improve data quality by up to 10 times and reduce mission costs by shifting toward a more flexible and extensible one-way radio navigation architecture," said Todd Ely, principal investigator of the Deep Space Atomic Clock Technology Demonstration at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The project is part of NASA's Technology Demonstration Missions program, managed by the Marshall Space Flight Center in Huntsville, Ala., for NASA's Office of the Chief Technologist in Washington.

The one-way deep space navigation enabled by DSAC uses the existing deep space network more efficiently than the current two-way system, thus expanding the network’s capacity without adding any new antennas or their associated costs. This is important, since future human exploration of deep space will demand more tracking from the deep space network than can currently be delivered with the existing system.

"The Deep Space Atomic Clock flight demonstration mission will advance this laboratory-qualified technology to flight readiness and will make a practical atomic clock available to a variety of space missions," Ely said.

The clock is a miniature mercury-ion atomic device the DSAC team will fly as a payload on an Earth orbiter in a one-year experiment to validate its operability in space and its usefulness for one-way navigation.

"A potential use for DSAC on a future mission would be in a follow-up to the Mars Reconnaissance Orbiter," Ely said. NASA's Mars Reconnaissance Orbiter launched to Mars in 2005 on a search for evidence that water existed on the planet's surface for enough time to provide a habitat for life. The orbiter completed its primary science phase in 2008 and continues to work in an extended mission. Atomic clocks are the most accurate timekeeping method known and are used as the primary standard for international time distribution services -- to control the frequency of television broadcasts, and in global navigation satellite systems such as the Global Positioning System.

NASA's WISE Catches Aging Star Erupting With Dust

Images from NASA's Wide-field Infrared Survey Explorer (WISE) reveal an old star in the throes of a fiery outburst, spraying the cosmos with dust. The findings offer a rare, real-time look at the process by which stars like our sun seed the universe with building blocks for other stars, planets and even life.

The star, catalogued as WISE J180956.27-330500.2, was discovered in images taken during the WISE survey in 2010, the most detailed infrared survey to date of the entire celestial sky. It stood out from other objects because it glowed brightly with infrared light. When compared to images taken more than 20 years ago, astronomers found the star was 100 times brighter.

"We were not searching specifically for this phenomenon, but because WISE scanned the whole sky, we can find such unique objects," said Poshak Gandhi of the Japan Aerospace Exploration Agency (JAXA), lead author of a new paper to be published in the Astrophysical Journal Letters.

Results indicate the star recently exploded with copious amounts of fresh dust, equivalent in mass to our planet Earth. The star is heating the dust and causing it to glow with infrared light.

"Observing this period of explosive change while it is actually ongoing is very rare," said co-author Issei Yamamura of JAXA. "These dust eruptions probably occur only once every 10,000 years in the lives of old stars, and they are thought to last less than a few hundred years each time. It's the blink of an eye in cosmological terms."

The aging star is in the "red giant" phase of its life. Our own sun will expand into a red giant in about 5 billion years. When a star begins to run out of fuel, it cools and expands. As the star puffs up, it sheds layers of gas that cool and congeal into tiny dust particles. This is one of the main ways dust is recycled in our universe, making its way from older stars to newborn solar systems. The other way, in which the heaviest of elements are made, is through the deathly explosions, or supernovae, of the most massive stars.

"It's an intriguing glimpse into the cosmic recycling program," said Bill Danchi, WISE program scientist at NASA Headquarters in Washington. "Evolved stars, which this one appears to be, contribute about 50 percent of the particles that make up humans."

Astronomers know of one other star currently pumping out massive amounts of dust. Called Sakurai's Object, this star is farther along in the aging process than the one discovered recently by WISE.

After Poshak and his team discovered the unusual, dusty star with WISE, they went back to look for it in previous infrared all-sky surveys. The object was not seen at all by the Infrared Astronomical Satellite (IRAS), which flew in 1983, but shows up brightly in images taken as part of the Two Micron All-Sky Survey (2MASS) in 1998.

Poshak and his colleagues calculated the star appears to have brightened dramatically since 1983. The WISE data show the dust has continued to evolve over time, with the star now hidden behind a very thick veil. The team plans to follow up with space- and ground-based telescopes to confirm its nature and to better understand how older stars recycle dust back into the cosmos.

Dark Heart of a Cosmic Collision


Infrared and X-ray observations from two space telescopes have been combined to create a unique look at violent events within the giant galaxy Centaurus A. The observations strengthen the view that the galaxy may have been created by the cataclysmic collision of two older galaxies.

The infrared light was captured by the European Space Agency's Herschel Space Observatory, a mission with important NASA contributions. The X-ray observations were made by the European Space Agency's XMM-Newton space telescope.

Centaurus A is the closest giant elliptical galaxy to Earth, at a distance of around 12 million light-years. It stands out because it harbors a massive black hole at its core and emits intense blasts of radio waves.

While previous images taken in visible light hinted at the complex inner structure in Centaurus A, combining the output of two orbiting observatories working at almost opposite ends of the electromagnetic spectrum has revealed the unusual structure in much greater detail.

The galaxy was observed by astronomer Sir John Herschel in 1847 during his survey of the southern skies. Now, more than 160 years later, the observatory bearing his family name has played a unique role in uncovering some of its secrets.

With the Herschel observatory, the giant black scar of obscuring dust crossing the center of Centaurus A all but disappears when viewed at long infrared wavelengths. The images show the flattened inner disk of a spiral galaxy, the shape of which scientists believe is due to a collision with an elliptical galaxy during a past epoch.

The Herschel data also uncover evidence for intense star birth toward the center of the galaxy, along with two jets emanating from the galaxy's core -- one of them 15,000 light-years long. Newly discovered clouds co-aligned with the jets can also be seen in Herschel's view.

The XMM-Newton X-ray observatory recorded the high-energy glow from one of the jets, extending more than 12,000 light-years away from the galaxy's bright nucleus. XMM-Newton's view shows not only the way that the jet interacts with the surrounding interstellar matter, but also the galaxy's intensely active nucleus, and its large gaseous halo.

The jets seen by both satellites are evidence of the supermassive black hole --10 million times the mass of our sun -- at the center of the galaxy.

New Ideas Sharpen Focus for Greener Aircraft


Leaner, greener flying machines for the year 2025 are on the drawing boards of three industry teams under contract to the NASA Aeronautics Research Mission Directorate's Environmentally Responsible Aviation Project.

Teams from The Boeing Company in Huntington Beach, Calif., Lockheed Martin in Palmdale, Calif., and Northrop Grumman in El Segundo, Calif., have spent the last year studying how to meet NASA goals to develop technology that would allow future aircraft to burn 50 percent less fuel than aircraft that entered service in 1998 (the baseline for the study), with 50 percent fewer harmful emissions; and to shrink the size of geographic areas affected by objectionable airport noise by 83 percent.

"The real challenge is we want to accomplish all these things simultaneously," said ERA project manager Fay Collier. "It's never been done before. We looked at some very difficult metrics and tried to push all those metrics down at the same time."

So NASA put that challenge to industry – awarding a little less than $11 million to the three teams to assess what kinds of aircraft designs and technologies could help meet the goals. The companies have just given NASA their results.

"We'll be digesting the three studies and we'll be looking into what to do next," said Collier.

Boeing's advanced vehicle concept centers around the company's now familiar blended wing body design as seen in the sub-scale remotely piloted X-48, which has been wind tunnel tested at NASA's Langley Research Center and flown at NASA's Dryden Flight Research Center. One thing that makes this concept different from current airplanes is the placement of its Pratt & Whitney geared turbofan engines. The engines are on top of the plane's back end, flanked by two vertical tails to shield people on the ground from engine noise. The aircraft also would feature an advanced lightweight, damage tolerant, composite structure; technologies for reducing airframe noise; advanced flight controls; hybrid laminar flow control, which means surfaces designed to reduce drag; and long-span wings which improve fuel efficiency.

Lockheed Martin took an entirely different approach. Its engineers proposed a box wing design, in which a front wing mounted on the lower belly of the plane is joined at the tips to an aft wing mounted on top of the plane. The company has studied the box wing concept for three decades, but has been waiting for lightweight composite materials, landing gear technologies, hybrid laminar flow and other tools to make it a viable configuration. Lockheed's proposal combines the unique design with a Rolls Royce Liberty Works Ultra Fan Engine. This engine has a bypass ratio that is approximately five times greater than current engines, pushing the limits of turbofan technology.

Supersonic Research Fleet Grows at Kennedy


The final pieces of a unique squadron of supersonic fighters arrived at NASA's Kennedy Space Center in Florida on Thursday, Jan. 19, where they will be reassembled and put to work with a private company aiming to use them for research and microgravity training.

The new planes were part of a group of five F-104 fighters bought by Starfighters Inc. from the Italian Air Force. The company already had four of the aircraft, but that wasn't enough for the company to pursue a number of different opportunities.

With nine aircraft at his disposal, Starfighters owner Rick Svetkoff said there will always be aircraft available to fly missions for a variety of customers. As importantly, the company will have what it needs to fly two aircraft on a single mission, with one serving as a chase plane to photograph experiments.

"Now we're in a position where we can really start operations," Svetkoff said. "Before, we couldn't do a lot of things we wanted to do."

Starfighters operates out of a hangar at the Shuttle Landing Facility at Kennedy under an agreement with Kennedy. Svetkoff's main goal is to fly research and development missions, ranging from experiments flown for universities to evaluating rocket and spacecraft components in high-stress environments including high-acceleration and microgravity.

Space Florida and Embry-Riddle University already have partnerships with the company.

Because the aircraft can soar to some 70,000 feet and speed past Mach 2, it can be used to launch small satellites into space. The 19-foot-long, 900-pound rocket, about the size of a Sparrow missile, has already been tested in a series of taxi runs hanging from an F-104's wings.

Test flights carrying the rocket but not launching it will be conducted in the next month and the first launch is in works to take place in the summer.

The rocket is meant to take small experiments into space but not into orbit. Instead, the rocket will parachute back to Earth and be recovered from the ocean for reuse. Svetkoff expects to launch about 100 suborbital missions a year from the Starfighters.

In less than a year, though, Svetkoff said he expects to start launching nanosatellites into orbit using a similar approach. After all, an F-104 can match a rocket's launch performance in some areas.

The F-104 Starfighter is a decades-old, supersonic fighter design that was put into service during the Cold War to intercept Soviet aircraft. Known as "the missile with a man in it" because of its high speed and stubby wings, the fighter was developed by Lockheed Martin's Kelly Johnson, the aerospace icon who also developed the SR-71 and U-2 aircraft.

Able to reach a top speed of Mach 2.4 and fly to about 70,000 feet, the F-104 found a second career with NASA in the 1960s. It helped train astronauts for microgravity and to keep their skills up in the demanding world of high-speed flight.

"Anything an F-16 or an F-18 can do, we can do with this aircraft, performance-wise," Svetkoff said.

The Starfighters fleet includes a mix of single-seat versions and two-seaters, each playing specific roles for the company.

Research and development flights are expected to add another 100 missions to the Starfighters' log each year, Svetkoff said.

The experimentation is not expected to end with machinery and experiments, though. As private companies develop their own spacecraft to launch humans into space in partnerships with NASA, some of those companies are already talking about using the Starfighters to train for microgravity and other situations, just as NASA's astronauts did in past decades.

For the moment though, the attention is on getting the new aircraft cleaned and assembled. The engines and other components will be taken apart and cleaned, and then put back together. New avionics packages including digital displays will be added to the new aircraft, too. It will take about three months to complete the first one, but the squadron should be ready in six months.

"This shows a serious commitment," Svetkoff said.

Add Salt? Astronauts' Bones Say Please Don't


Osteoporosis is a harsh disease that reduces the quality of life for millions and costs Europe around €25 billion ($31 billion) each year. It typically affects the elderly, so the rise in life expectancy in developed countries means the problems inflicted by osteoporosis are increasing.

Fortunately, research done in space may change the game. Astronauts on the International Space Station experience accelerated osteoporosis because of weightlessness, but it is carefully controlled, and they can regain their lost bone mass once they are back on Earth.

Studying what happens during long spaceflights offers a good insight into the process of osteoporosis -- losing calcium and changing bone structure -- and helps to develop methods to combat it.

It has been known since the 1990s that the human body holds on to sodium, without the corresponding water retention, during long stays in space. But the textbooks said this was not possible. "Sodium retention in space" became an important subject to study.

Salt intake was investigated in a series of studies, in ground-based simulations and in space, and it was found that not only is sodium retained (probably in the skin), but it also affects the acid balance of the body and bone metabolism. So, high salt intake increases acidity in the body, which can accelerate bone loss.

The European Space Agency's, or ESA’s, recent SOdium LOad in microgravity, or SOLO, study zoomed in on this question. Nine crew members, including ESA's Frank De Winne and Paolo Nespoli during their long-duration flights in 2010 and 2011, followed low -- and high-salt diets. The expected results may show that additional negative effects can be avoided either by reducing sodium intake or by using a simple alkalizing agent like bicarbonate to counter the acid imbalance.

This space research directly benefits everybody on Earth who is prone to osteoporosis.

Astronauts seen as well as heard


Seeing ESA astronaut Andre Kuipers on the International Space Station is a regular incidence these days. You turn on your TV or check Twitter and there he is. Since present are no cable sprawling from the Station to Earth, just how does this come about?

The reply, of course, is via satellite. While the reply may be simple, the method is more complex. Behind Andre's smiling face is a compound system of jargon-filled amplifiers, multiplexers, antennas, nodes and signal modulation.

Thanks to satcoms, the team can directly take delivery of emails on the Space Station, they can create private calls via IP phones, and we can see them during televise video conference.

The Station is airborne in a low orbit - around 400 km up - which income that shortest communications can happen only when it passes over a ground station. In its place, signals from the Station are primary sent to 'geostationary' satellites balanced 36 000 km above the equator.

Geostationary satellites take precisely a day to circle Earth, creation them appear stationary in our skies. This allows continuous contact with ground stations; enable them to communicate the Station's signals to a middle ground station on Earth additional often.The procedure is upturned when sites such as the Columbus control centre in Munich, Germany, send signal up to the Station.

Goddard Director Leaving for Ball Aerospace

Robert Strain will leave as director of  NASA’s Goddard Space Flight Center in Greenbelt, Md., to turn out to be chief operating officer of Ball Aerospace & Technologies Corp. Strain’s last day at Goddard will be March 4, NASA spokesman Mark Hess said. damage, who has detained the top post at Goddard for more than three years, announced his acceptance Jan. 30.

 NASA has not yet selected a substitute for Strain, Hess said.

 At Boulder, Colo.-based Ball, Strain will be accountable for day-to-day operation of the company’s Civil and Operational Space, Tactical Solutions, National Defense, and system Engineering Solutions units. He will report in a straight line to David Taylor, president and chief executive of Ball Aerospace.

 Before taking the wheel of Goddard in 2008, Strain was the head of the Space Department at the Johns Hopkins University Applied Physics Lab in Laurel, Md. Prior to joining Hopkins in 2004, Strain exhausted 10 years at Dulles, Va.-based satellite and rocket maker Orbital Sciences Corp., where he was decision-making vice president of space systems.

Ball is working on more than a few big projects being managed by Goddard. Among these is the Joint Polar Satellite System (JPSS), the next-generation of U.S. civil polar-orbiting weather satellites.

Ball is the prime contractor for the JPSS-1 spacecraft, which NASA is procuring for the National Oceanic and Atmospheric management. Ball has a $248 million fixed-price contract to build JPSS-1, and a separate $82.4 million contract to construct a clone of the Ozone map and Profile Suite instrument.

The 2012 budget for JPSS is $924 million.
