Europe's automatic move Vehicle is incorporated on Ariane 5

The third European Automated Transfer Vehicle (ATV) for open by Arianespace was installing atop its Ariane 5 at the Spaceport, mark one of the final steps in arrangements for a March 9 liftoff on a service mission to the International Space Station.

Named after Italian physicist Edoardo Amaldi, the ATV will take dry cargo (including food, clothing, experiments and spare parts), along with water, gas and propellant for delivery to the crewed orbital ability.

This latest ATV flight in support of International Space Station operations will utilize an Ariane 5 ES version of Arianespace's heavy-lift workhorse, underscoring the launcher's suppleness in meeting a full range of mission requirements. The launch of ATV Edoardo Amaldi follows Arianespace missions with Europe's first two Automated Transfer Vehicles, perform in February 2011 and March 2008 from the Spaceport in French Guiana.

An industry consortium led by Astrium produces the ATVs in a program manage by the European Space Agency.

Mars Science Laboratory Mission rank account

Engineers have established the root reason of a computer rearrange that occur two months ago on NASA's Mars Science Laboratory and have strong-minded how to right it.

The fix involves altering how certain vacant data-holding locations, called registers, are configured in the memory management of the kind of computer chip used on the spacecraft. Billions of run on a test computer with the personalized register pattern yielded no repeat of the reset behavior. The assignment team made this software change on the spacecraft's PC last week and long-established this week that the update is winning.

Three days after launch, during use of the craft's star scanner. The cause has been recognized as a previously unknown design peculiarity in the memory organization unit of the Mars Science Laboratory computer processor. In rare set of situation unique to how this mission uses the processor, cache access errors could occur, resulting in instructions not being executed properly. This is what happen on the spacecraft.

"Good police officer work on thoughtful why the rearrange occurred has yielded a way to avert it from occurring again," said Mars Science Laboratory Deputy Project Manager Richard Cook of NASA's Jet Propulsion Laboratory, Pasadena, Calif. "The winning resolution of this difficulty was the ending of productive teamwork by engineers at the computer producer and JPL."

Vega rocket prepared for first flight

 The primary Vega launch campaigns begin in November with the fitting of the P80 first stage on the launch pad. The two solid-propellant second and third stages were additional to the vehicle; follow by the AVUM – Attitude & Vernier Upper component – liquid-propellant fourth stage.  

All four stages have undergone concluding acceptance, counting the difficult of the avionics, leadership, telemetry, propulsion, division pyrotechnics and safety systems.

These steps culminate on 13 January with Vega’s ‘mixture control checks’, where all systems were put into launch mode for the vehicle’s final acceptance. This included pressurising the AVUM propulsion systems that actuate the thruster valves.

The rocket’s elements were switch on from the manage bench to replicate the launch countdown. The onboard software then took in excess of and replicated the diverse stages of a flight. The interface between the vehicle and the control bench were also tested.

NASA's James Webb Space Telescope: A time of accomplishment and achievement

Manufacturing and difficult of all flight mirrors was finished in a final test at the X-ray and Calibration Facility at Marshall Space Flight Center, Huntsville, Ala. through these tests mirror segment were chilled to temperature similar to those Webb will see in space, around minus 400 degrees Fahrenheit.

It was the conclusion of work started in 2003. Heed lessons learned from the Hubble Space Telescope, the program adopted the plan of tackling the most difficult technical challenges first. That decision proved to be the right one. In June, all 18 flight main mirror segment, plus the secondary, tertiary and fine steering mirrors, were refined and coated soft beautiful surfaces that will enable Webb to image the most far-away galaxies.

Two of Webb's behind and leader structures were also completed. To assemble the flight telescope on the ground, a 139,000 pound structure will install the flight mirrors using an below track system supporting a robotic arm. The huge display place has been completed and assembled in the ultra-clean room used for telescope assembly at Goddard.

Also over was the pathfinder backplane, a full-scale engineering model of the middle section of the flight backplane. The backplane holds the mirror segment in place to form a single primary mirror. The full pathfinder constituent will consist of 12 of the 18 hexagonal cells (the center section of the primary mirror) of the telescope and contain a subset of two primary mirror segment assemblies, the secondary mirror, and the subsystem contain the tertiary and fine direction-finding mirrors. It will show integration and test actions that will be used on the flight reduce in size.

Webb's giant sunshield moved onward into a new testing phase last year, the last step before fabrication of the flight sunshield. Sunshield layer three became the first of five full-size flight-like layers stretched out in a fully replicated flight pattern. This enables engineers to make 3-D shape capacity that will tell them how the full-size sunshield layers will behave in space. Implementation this test is a critical step in the sunshield's progress and gives the engineers confidence and experience needed to manufacture the five flight layers.

An important sunshield use flight structure also completed fabrication in 2011. The space-qualified graphite composite tubes that will enable the sunshield to deploy in space have finished fabrication. The telescoping tube system was intended at Astro Aerospace, a industry unit of Northrop Grumman.

Capping the year's achievement, Webb's spacecraft also moved onward. The force system's 16 monopropellant rocket engine thrusters, which manage momentum and station-keeping on orbit, were upgraded to accept senior heat loading from the sunshield. Propulsion engineers also completed building four flight secondary combustion increased thrusters which maintain orbit after the launch vehicle finishes its burns. Engineers also established the flight software accountable for ground commands and science data liberation.

Successor to the Hubble Space Telescope, the James Webb Space Telescope is the world's next-generation space observatory. It is the most influential space telescope ever built. Webb will observe the most remote objects in the universe, provide images of the very first galaxies ever formed and study planets around distant stars. The Webb reduce in dimension is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

Fifty-Seven Student Rocket Teams to Take NASA Launch Challenge

More than 500 students from middle schools, high schools, colleges and universities in 29 states will show their rocketeering prowess in the 2011-12 NASA Student Launch Projects flight challenge. The teams will build and test large-scale rockets of their own design in April 2012.

NASA created the twin Student Launch Projects to spark students' imaginations, challenge their problem-solving skills and give them real-world experience. The project aims to complement the science, mathematics and engineering lessons they study in the classroom.

"Just as NASA partners with innovative companies such as ATK to pursue the nation's space exploration mission, these young rocketeers pool their talent and ingenuity to solve complex engineering problems and fly sophisticated machines,” said Tammy Rowan, manager of Marshall's Academic Affairs Office.

A record 57 teams of engineering, math and science students will take part in the annual challenge, organized by NASA's Marshall Space Flight Center in Huntsville, Ala. Fifteen middle and high school teams will tackle the non-competitive Student Launch Initiative, while 42 college and university teams will compete in the University Student Launch Initiative. The latter features a $5,000 first-place award provided by ATK Aerospace Systems of Salt Lake City, Utah.

"This competition is extremely important to ATK to mentor and train our future workforce," said Charlie Precourt, ATK general manager and vice president of Space Launch Systems. Precourt is a former space shuttle astronaut who piloted STS-71 in 1995 and commanded STS-84 in 1997 and STS-91 in 1998. "ATK is proud to enter our fifth year as a partner with NASA on this initiative to engage the next generation. The competition grows in impact each year."

Each Student Launch Projects team will build a powerful rocket, complete with a working science or engineering payload, which the team must design, install and activate during the rocket launch. The flight goal is to come as close as possible to an altitude of 1 mile, requiring a precise balance of aerodynamics, mass and propulsive power.

As in classroom studies, participants must "show their work," writing detailed preliminary and post-launch reports and maintaining a public website for their rocket-building adventure. Each team also must develop educational engagement projects for schools and youth organizations in its community, inspiring the imaginations and career passions of future explorers.

In April, the teams will converge at Marshall, where NASA engineers will put the students' creations through the same kind of rigorous reviews and safety inspections applied to the nation's space launch vehicles. On April 21, 2012, students will firing their rockets toward the elusive 1-mile goal, operating onboard payloads and waiting for chutes to open, signaling a safe return to Earth.

The student teams will vie for a variety of awards for engineering skill and ingenuity, team spirit and vehicle design. These include two new prizes: a pair of TDS2000 Series oscilloscopes, which are sophisticated tools for studying the change in flow of electrical voltage or current. Donated by Tektronix Inc. of Beaverton, Ore., the oscilloscopes will be presented to the two school teams that earn the "Best Payload" and "Best Science Mission Directorate Challenge Payload" honors.

This year's participants hail from Alabama, Arkansas, California, Colorado, Florida, Georgia, Hawaii, Iowa, Illinois, Indiana, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, Missouri, Mississippi, North Carolina, North Dakota, Nebraska, New Mexico, New York, Pennsylvania, Tennessee, Texas, Utah, Virginia, Washington and Wisconsin.

Science Nugget: Using Many Instruments to Track a Comet

In 16 years of data observations, the Solar Heliophysics Observatory (SOHO) -- a joint European Space Agency and NASA mission –- made an unexpected claim for fame: the sighting of new comets at an alarming rate. SOHO has spotted over 2100 comets, most of which are from what's known as the Kreutz family, which graze the solar atmosphere where they usually evaporate completely.

But on December 2, 2011, the discovery of a new Kreutz-family comet was announced. This comet was found the old-fashioned way: from the ground. Australian astronomer Terry Lovejoy spotted the comet, making this the first time a Kreutz comet has been found through a ground-based telescope since the 1970's. The comet has been designated C/2011 W3 (Lovejoy).

Discovering a comet before it moves into view of space-based telescopes, gives scientists the opportunity to prepare the telescopes for the best possible observations. Indeed, since comet Lovejoy was visible from the ground, scientists have high hopes that this might be an exceptionally bright comet, making it all the easier to view and study. (Some Kreutz comets –- such as Ikeya-Seki in 1965 -- are so bright they can be seen with the naked eye in the daytime, though this is extremely rare.)

The comet moved into view of the Solar Terrestrial Relations Observatory (STEREO) on Monday, December 12. It should be visible in SOHO by Wednesday, Dec 14.

Next up is Hinode, which will make observations at about 6 p.m. ET on Dec 15, as the comet moves towards its closest approach to the sun. Hinode's solar optical telescope will take the highest resolution images of this close approach. As the comet passes through the sun's atmosphere, the corona, an increase in particle collisions may produce X-rays, so Hinode may also capture X-ray images of the comet.

The comet will likely pass within some 87,000 miles of the sun, and disappear behind the northwest limb of the sun shortly after it is seen by Hinode.

JEFF ADAMS - ADVANTAGES OF REAL ESTATE INVESTING

•    Every investment has advantage and disadvantages. In the case of land, it responds slower than stock markets.

•    There are options to influence. The best thing about real estate investing according to Jeff Adams is that there are many options that are available to real estate investor allowing them to borrow money whenever they want to purchase new property. It is beneficial to investors who don’t have upfront cash. This kind of options are not available in the case of shares in which the trade permitted is limited, while in property investments, you don’t need to stick to any restrictions.

•    Investors can also purchase properties that are below market value such as foreclosed properties that are intense in the real estate market today. They are sold at very cheap prices and you can choose from a group of properties in order for you to find the most cost-effective property that can bring you profits in the future.

•    Numerous bonuses are offered to real estate investors such as tax benefits. In addition to this, investors can go well with the reduction choice. Investors are given support by the government to permit their property to have a useful life.

•    Real estate investors are given power to quote price for their property. This is another benefit of real estate investing over stock investments. Real estate investors can add value to the property by making adding enrichments such as renovating the property by constructing swimming pool, garage and extra rooms. By doing this, the property is added with considerable value and investors are given full control in quoting the price of the property.

These are the important tips newbie investors must learn before they get into the real estate market. Jeff Adams scam may sound daunting to most people, but there is no evidence that Jeff Adams would only want money from you. In fact, these tips are intended to help you make money in your investing career.

Shuttle Model Move Shows Way for Atlantis

Moving the high fidelity model of the space shuttle Dec. 10 called for an array of planning, about 100 people and a specialized trailer. It also called for the temporary removal of 18 light poles, four traffic signals and some signs.

It took the team about five hours to make the six-mile trip from the Kennedy Space Center Visitor Complex to the Turn Basin across the street from the Vehicle Assembly Building. The group started rolling at 7:30 a.m. so they wouldn't have to worry about the dark.

"It went very well," said Gerald "Jay" Green, project manager for the move. "I felt a great sense of accomplishment when we got it done."

A similar move will be made next year when space shuttle Atlantis is taken the opposite direction to its display location at the Visitor Complex.

The model's convoy never traveled more than about 6 mph. It came to a stop many times along the way so the trailer's built-in jacks could raise or lower the wings to get past obstacles such as guard shacks and traffic lights.

"There were four or five really hard spots," Green said.

But then, moving space shuttles and full-scale model shuttles has always required extra consideration. For instance, crews moving a space shuttle through the mountains in California had to cut slots in the rock to make room for the wings.

Moving the model didn't require such an extreme action, but it took a month of planning and considerable study of potential routes. Even 3-D modeling was incorporated to find problem zones. All this was before Green and his group found out they would have to move it with the wings attached.

The first plans called for the model's wings to be cut off, but that decision was changed, forcing Green to model for a wingspan of 78 feet, not just the relatively narrow fuselage.

"We had to redo the plan in about a week," Green said. "We knew we would eventually have to take Atlantis, so we had to figure out what would make it work."

Some of the workers were on hand in case more signs or other hardware had to be removed as the model made its way.

Beyel Bros., a heavy lifting and hauling contractor, used a specialized trailer that had lifts built in, along with 144 wheels that could turn and swivel so the trailer could move nearly sideways if needed.

The tightest fit came when the wings crossed within six inches of a railroad crossing sign.

The shuttle model took a different route through the center, including going the "wrong way" on an entrance ramp to avoid going beneath the bridge over Kennedy Parkway. With tour buses and other traffic detoured to the other side of the parkway, the model moved north on the southbound side.

The model is expected to remain at the Turn Basin until February, when it will be taken on an open barge to Texas for display at Space Center Houston, the visitor center for NASA's Johnson Space Center.

The model, which weighs some 130,000 pounds, about the same as a real shuttle, is outfitted with doors and people toured the inside of it for years at the Visitor Complex.

"You can go in it, which I think is a great thing," Green said. "It's going somewhere where it's going to be used and enjoyed."

NASA Flies Robotic Lander Prototype to New Heights

NASA successfully completed the final flight in a series of tests of a new robotic lander prototype at the Redstone Test Center’s propulsion test facility on the U.S. Army Redstone Arsenal in Huntsville, Ala. Data from this test series will aid in the design and development of a new generation of small, smart, versatile robotic landers capable of performing science and exploration research on the surface of the moon or other airless bodies in the solar system, such as asteroids or the planet Mercury.

Since early October, the Robotic Lander Development Project at NASA's Marshall Space Flight Center in Huntsville has subjected the lander prototype to a series of more complex outdoor flight tests maneuvers. The team steadily increased the lander's flight profile, starting by hovering the lander – dubbed Mighty Eagle -- at 3 feet, then 30 feet and finally a record 100-foot flight test.

During the 100-foot flight test, the lander autonomously flew for 30 seconds. The Mighty Eagle ascended to 100 feet, hovered and then demonstrated the equivalent of an autonomous landing on the lunar surface. The final maneuver simulated the required descent approach by horizontally translating 30 feet while descending and landing on target. The test demonstrated the lander's ability to maneuver to avoid hazards before performing a safe, controlled landing.

"The successful completion of the Mighty Eagle lander prototype provides a high level of confidence in our flight system design which significantly reduces cost and schedule," said Julie Bassler, Robotic Lander Development project manager at NASA's Marshall Space Flight Center in Huntsville. "Our combined NASA and contractor team went from the drawing board to successfully flight testing an autonomous, closed-loop, lander prototype system in less than two years," she said. "Mighty Eagle has performed well, demonstrating precision ascents, descents and horizontal translation flights to prove the lander can control itself and land safely."

"Our small team has worked tirelessly to develop a robust lander system," said Dr. Greg Chavers, lead systems engineer for the Robotic Lander Development Project at Marshall. "The prototype lander has the capability to launch, descend and land safely on its own -- without a man in the loop -- demonstrating the lander's autonomous and reusable test capability. Our team has matured the lander's guidance, navigation and control algorithms, which provided stable control of the lander, even through light wind and rain."

Mighty Eagle is a three-legged prototype that resembles an actual flight lander design. It is 4 feet tall and 8 feet in diameter and weighs 700 pounds when fueled with 90 percent hydrogen peroxide.

The lander receives its commands from an onboard computer that activates its 16 onboard thrusters -- 15 pulsed and one gravity cancelling thruster -- to carry it to a controlled landing using a pre-programmed flight profile. The prototype serves as a platform to develop and test algorithms, sensors, avionics, software, landing legs, and integrated system elements to support autonomous landings on airless planetary bodies, where aero-braking and parachutes are not options.

The next test phase of the test series is set to resume in early Spring when weather is more favorable for outdoor flight test. This new test series will test enhanced navigation capabilities.

Development and integration of the lander prototype is a cooperative endeavor led by the Robotic Lunar Lander Development Project at the Marshall Center; Johns Hopkins Applied Physics Laboratory; and the Von Braun Center for Science and Innovation, which includes the Science Applications International Corporation, Dynetics Corp., Teledyne Brown Engineering Inc., and Millennium Engineering and Integration Company, all of Huntsville.

The project is partnered with the U.S. Army’s Test and Evaluation Command’s test center located at Redstone Arsenal. The Redstone Test Center is one of six centers under the U.S. Army Test and Evaluation Command and has been a leading test facility for defense systems since the 1950s. Utilizing an historic test site at the arsenal, the project is leveraging the Redstone Test Center’s advanced capability for propulsion testing.

NASA's Hubble Finds Stellar Life and Death in a Globular Cluster

A new NASA Hubble Space Telescope image shows globular cluster NGC 1846, a spherical collection of hundreds of thousands of stars in the outer halo of the Large Magellanic Cloud, a neighboring dwarf galaxy of the Milky Way that can be seen from the southern hemisphere.

Aging bright stars in the cluster glow in intense shades of red and blue. The majority of middle-aged stars, several billions of years old, are whitish in color. A myriad of far distant background galaxies of varying shapes and structure are scattered around the image.

The most intriguing object, however, doesn’t seem to belong in the cluster. It is a faint green bubble near the bottom center of the image. This so-called ‘planetary nebula’ is the aftermath of the death of a star. The burned-out central star can be seen inside the bubble. It is uncertain whether the planetary nebula is a member of NGC 1846, or simply lies along the line of sight to the cluster. Measurements of the motion of the cluster stars and the planetary nebula’s central star suggest it might be a cluster member.

Lightning-made Waves in Earth's Atmosphere Leak Into Space

At any given moment about 2,000 thunderstorms roll over Earth, producing some 50 flashes of lightning every second. Each lightning burst creates electromagnetic waves that begin to circle around Earth captured between Earth's surface and a boundary about 60 miles up. Some of the waves – if they have just the right wavelength – combine, increasing in strength, to create a repeating atmospheric heartbeat known as Schumann resonance. This resonance provides a useful tool to analyze Earth's weather, its electric environment, and to even help determine what types of atoms and molecules exist in Earth's atmosphere, but until now they have only ever been observed from below.

Now, NASA's Vector Electric Field Instrument (VEFI) aboard the U.S. Air Force's Communications/Navigation Outage Forecast System (C/NOFS) satellite has detected Schumann resonance from space. This comes as a surprise, since current models of Schumann resonance predict these waves should be caged at lower altitude, between the ground and a layer of Earth's atmosphere called the ionosphere.

"Researchers didn't expect to observe these resonances in space," says Fernando Simoes, a scientist at NASA's Goddard Space Flight Center in Greenbelt, Md. "But it turns out that energy is leaking out and this opens up many other possibilities to study our planet from above."

Simoes is the first author on a paper about these observations that appeared online in the journal Geophysical Research Letters on November 16 and will appear in the print publication in December. He explains that the concept of resonance in general is fairly simple: adding energy at the right time will help any given phenomenon grow. Think of a swing – if you push it back just as it hits the top of its arc, you add speed. Push it backwards in the middle of its swing, and you will slow it down. When it comes to waves, resonance doesn't occur because of a swing-like push, but because a series of overlapping waves are synchronized such that the crests line up with the other crests and the troughs line up with the other troughs. This naturally leads to a much larger wave than one where the crests and troughs cancel each other out.

The waves created by lightning do not look like the up and down waves of the ocean, but they still oscillate with regions of greater energy and lesser energy. These waves remain trapped inside an atmospheric ceiling created by the lower edge of the "ionosphere" – a part of the atmosphere filled with charged particles, which begins about 60 miles up into the sky. In this case, the sweet spot for resonance requires the wave to be as long (or twice, three times as long, etc) as the circumference of Earth. This is an extremely low frequency wave that can be as low as 8 Hertz (Hz) – some one hundred thousand times lower than the lowest frequency radio waves used to send signals to your AM/FM radio. As this wave flows around Earth, it hits itself again at the perfect spot such that the crests and troughs are aligned. Voila, waves acting in resonance with each other to pump up the original signal.

While they'd been predicted in 1952, Schumann resonances were first measured reliably in the early 1960s. Since then, scientists have discovered that variations in the resonances correspond to changes in the seasons, solar activity, activity in Earth's magnetic environment, in water aerosols in the atmosphere, and other Earth-bound phenomena.

"There are hundreds, maybe thousands, of studies on this phenomenon and how it holds clues to understanding Earth's atmosphere," says Goddard scientist Rob Pfaff, Principal Investigator of the VEFI instrument and an author on the GRL paper. "But they're all based on ground measurements."

C/NOFS, of course, measured them much higher – at altitudes of 250 to 500 miles. While models suggest that the resonances should be trapped under the ionosphere, it is not unheard of that energy can leak through. So the team began looking for waves of the correct, very low frequency in the observations from VEFI – an instrument built at NASA Goddard with high enough sensitivity to spot these very faint waves. And the team was rewarded. They found the resonance showing up in almost every orbit C/NOFS made around Earth, which added up to some 10,000 examples.

Detection of these Schumann resonances in space requires, at the very least, an adjustment of the basic models to incorporate a "leaky" boundary at the bottom of the ionosphere. But detecting Schumann resonance from above also provides a tool to better understand the Earth-ionosphere cavity that surrounds Earth, says Simoes.

"Combined with ground measurements, it provides us with a better way to study lightning, thunderstorms, and the lower atmosphere," he says. "The next step is to figure out how best to use that tool from this new vantage point."
