Holographic Projection Glide Paths


Holographic Technologies are getting closer to becoming reality and soon we can see the data on our computers in 3D, 4D and 5D. We will enjoy Virtual Reality on our 360 X-Box in our living rooms. Military strategists and war fighters can play out the battle in the virtual battlespace in advance and then watch it un-fold in real time. Great, great grandchildren will be about to meet their past ancestors and watch a holographic video. We will communicate in video conferencing with the image of the other people sitting next us, but not actually there. All this is on its way and even more, as the applications are endless indeed.

One application, which has not been mentioned, yet is the potential for pilots to have projected glide paths in front of them as they fly, actually watching their aircraft (full-size) in front of them. All they will have to do is follow the projection and match their aircraft to the angles and speeds of the holographic aircraft ahead. The projection will be set for safest glide path, avoid wake turbulence and be the most fuel-efficient decent. This will make flying easier and become a great training tool for new pilots building hours and their skills.

This will insure a proper downwind to base and base to final approach, with perfect angles, no steep banks and help the pilot land at the perfect speed on the threshold. Additionally these Holographic Projections will be recorded and used for training air traffic controllers and used by flight instructors to watch to make sure the student pilot is coming along fine. The instructor will be able to reduce the scale of the aircraft to 1:24 or 1:48 scale and show student how they did. This can help in training new fighter pilots in the military as well. This can add to the simulator experience. Such technology will come in handy for the NASA SATS Program making general aviation safe as we move more private automobile traffic from our ground transportation infrastructures into the air and help with the Virtual Control Tower Simulation Training Systems to help commercial aviation.

Imagine eliminating wake turbulence accidents by helping pilots avoid wake turbulence, by using net-centric systems inside the aircraft, which will re-project the holographic aircraft in front of them. Good for collision avoidance as well. This will alleviate issues with the 3-minute rule, when it should be extended or when it is not a factor. The increased efficiency will help the traffic flow at the larger airports, moving more aircraft on their way in less time.

The Holographic Technology is almost here and it such advances in science has the potential of literally solving many safety and efficiency issues in aviation in the present period and safety in space in the next period. Think on this.

UFO: Futuristic Concepts and the End of the World


I was sitting on the front stoop wondering if I should wash the pickup or pick the last of the tomatoes off my one vine that has produced about a zillion marble-sized tomatoes this summer.

I learned last year that you only need one tomato plant in Idaho unless you want to supply (no derogatory remark here) Wal-Mart®. I accidentally picked a plant that pumps out those wee tomatoes that I didn’t like. I like the big ones that send juice running down your cheeks when you bite into them.

My granddaughter, L, loves the little ones and I found that if you get a handful and plunk them into your mouth all at the same time, like she does, you can get a big tomato sensation. I went out to my plant and grabbed a handful. That’s when Xrytspet showed up.

“I don’t see how you can eat those things!”

I said, “Go away, Xrytspet!”

She said, “I came to help. Is that how I’m to be treated?”

“What do you want, Xrytspet?”

“I’ve come to help you with that article you are thinking about.”

As is her custom, she sat on my lap. I said, “Get off my lap!”

“I want to help you with that Future-Concepts - Got futuristic dreams of changing the world? Put even your most eccentric or innovative ideas here! article for the new http://ezinearticles.com category.

“Sense when do I need you to help me write, Xrytspet? I’ve got my own ideas for the article.”

“They stink!”

“What do you mean, they stink? You’ve been in there messing with my computer, haven’t you?”

“I made a few revisions to your article.”

She kissed my cheek and disappeared after turning herself into a Northern Fish Crow, a Blue Bird, and a Northern Shriek.

Last week she turned herself into a cheetah, a puma, and a jaguar before she disappeared. The jaguar chased me up our cherry tree.

I decided to skip washing the pickup. It was getting cloudy in the west and maybe it would rain. I went into the computer and read her article which is as follows:

Futuristic Concepts and Dreams that Will Change the World Including Eccentric and Innovative Ideas. by Xrytspet and John T. Jones, Ph.D.

To determine the future we went to the Synchronic Isentropic Time Warp Predictor and typed in Earth. Here is the printout of significant events:

March 2017: Bush War II (Iraq) ends. The casualties not counting Iraqis (who don’t count) were 12337 Americans, 12 Australian, 987 Britons, 134 Bulgarians, 7 Danes, 9 Dutch, 14 Estonians, 9 Hungarian, 260 Italians, 3 Kazakh, 4 Latvian, 174 Poles, 4 Salvadoran, 6 Slovaks, 11 Spaniards, 8 Thai and 18 Ukrainians.

April 2034: Bush War II (Afghanistan) ends. The casualties not counting citizens of Afghanistan (who don’t count) were 1250 Americans, 8 Australian, 12 Britons, 16 Canadians, 12 Danes, 14 French, 45 Germans, 16 Italians, 5 Norwegian, 7 Romanians and 57 Spaniards. There were also Pakistani deaths (who don’t count).

January 2037: Cell Phone Production Wavers Off: Only 2.345 billion telephones were produced in 2036. The death count by drivers using cell phones reached 52,617 deaths and 7,260,006 injuries.

November 2248: Post revolutionaries attempt to bring freedom to the United States: Students from the University of Nevada, Tonopah called on President Valerie Clinton, a descendent of President Hillary Rodman Clinton, to convince the 47 states that left the Union last year to return and to start up Congress again. The President said, “Are you kidding? I can hardly manage the three states that are left (Utah, Nevada, and Idaho).”

October-December 2869: Meteor shower throw big ones at Aberdeen, Kansas and Aberdeen, Scotland. Most humanoids were killed in the two Aberdeens (and in their surrounding areas) during the recent rock show from the sky. A Mongolian horse breeder said, “At last! Now maybe I can raise my horses in peace without those National Geographic guys being around here all the time.”

February 2356: Nubian man creates fire from rubbing sticks together (Also called Kush, Land of Kush, Te-Nehesy, Nubadae, Napata, or the Kingdom of Meroei.) : Amun-Pa of Batn El Hajar or "Belly of Rocks" has discovered fire, something we all forgot. He lit a torch and ran all the way to the 6th Cataract above Khartoum. His run will be repeated at the First Nubian Olympics in September, at Khartoum, right after the hot season.

August 2459: Glaciers at Antarctica have all now melted. Geologists predict good beach conditions east of the underwater community of Sacramento, CA and at the lower elevations below Spruce Pine, NC.

June 2787: Astronomers apologize for not predicting the correct approach of Asteroid Humongous last fall. Speaking for the scientist at Area 51 near Los Vegas, Nevada, Dr. Alice Brown-Jones, a remote cousin of the famous cinema star, Catherine Zeta Jones that we have been watching on our television sets for decades, said in a news conference this morning at 1:17 a.m. that the trajectory of Asteroid Humongous was calculated incorrectly last fall and that the asteroid was going to hit the moon dead center rather than swishing by our earth sucking the ocean waters into the sky. (That would have been a sight!) She said that scientist at Area 51 near Los Vegas were calculating the consequences of this, but she suggested that we all take measures to learn the Nuclear Age Safe Position. As a public service we instruct you herewith:

1. Find a strong table or desk. (If you have a choice, choose the one in the cellar or basement.)

2. Sit under the desk or table.

3. Pull your legs up to your chin but keep your legs apart wide enough to kiss your butt goodbye.

End of Record

After I read this report, I was very relieved. None of this would affect me much.

Future-Concepts : Merit Pay For Teachers - How Will It Work?


Merit pay for teaching has been an unfulfilled goal of many teaching proponents for decades. There are examples that show it works elsewhere in this nation.

What about the private, entrepreneurial segments of America? Do they use rewards to recognize exemplary performance, as well as to motivate quality? One prominent performance measure in manufacturing is worker productivity. The more output a worker produces over a given time period, the higher the productivity quotient, with opportunity to increase earnings. In retail trade, customer satisfaction is a crucial measure of management focus. The healthcare sector uses trial studies to achieve success through improving patients' quality of life and lengthening life span. As diverse as these three enterprises are, they each remain worldly competitive by reducing errors. Through research and measurement, they isolate those areas of operation where most errors occur, and initiate practices to reduce those errors, with merit rewards as the prime incentive.

Although somewhat simplistic, it might be useful to identify the proven techniques that aid these employment segments with error reduction.

Goal Setting: With a continuing process in place for isolating error prone activities, goals that are observable and specific are stated in written form and communicated to all those involved in error reduction. Vague goals are easy to reach, but useless.

Computer-aided Technology Use: Creating software and/or hardware designed for alleviating tasks of a repetitive nature usually helps in reducing errors. Precision results are more likely to occur with technology use, than when humans perform the same tasks.

Decision Making: The responsibility for problem solving is usually best vested in persons closest to the problem. If you see it, fix it. Don't just call a specialist.

Merit Rewards: For that person who causes success above the level of expectation, their repeated performance at that level will more likely occur with merit recognition.

Entrepreneurial Competitive Support: American ingenuity remains the reason for surges in the unprecedented growth in start-up small business employment. This American service sector continues to grow, and create solutions wherever challenges exist.

COULD MERIT REWARDS WORK IN EDUCATION ?

Now, let's examine how well these techniques are, or could, benefit public education. If the private sector finds competitive success by implementing proven approaches for error reduction, could the public sector do the same? Perhaps attention to the elements that have made our American private sector the envy of the world would do the same for education.

Let's examine them one-by-one:

Goal Setting: This is one of the important sections of the Federal Policy "No Child Left
Behind" law. Each State is empowered with the task of writing, communicating and implementing specific, measurable student learning outcomes. This state-by-state process is moving slowly and many of the already published learning goals are not measurable, therefore no one can precisely agree if these stated student-goals have even been reached.

A practical solution to this dilemma would be an insistence that all goal statements contain action verbs that define observable human behaviors. One simple, but useful list of these verbs, arranged from simplest to most complex would be to: identify; distinguish; name; place in order; describe; contrast; state a rule; apply a rule; demonstrate; and interpret.
Not only would statements containing these verbs be observable, but they would also lead to measurability, a necessity for tracking learning progress with standardized testing.

Entrepreneurial Competitive Support: With the availability of goals containing observable academic behaviors, the task of preparing test questions focused on these outcomes becomes a precision task. Research by qualified test making companies can match questions to goals very precisely. At the present time these companies provide standardized achievement tests and scored test results.

But these results are of little use to teachers who need immediate feedback to diagnose areas for remediation. The thing that would be most useful to educators would be an Internet system that could electronically supply teachers with short classroom quizzes and instant scoring.

Unique tests of any length could be downloaded, based on the teacher's subject choice of item characteristics, available from the test company's large test-item database.

Other support organizations might offer a way to provide the quiz according to teacher-chosen curriculum characteristics, but with each student in the class receiving only a few questions. And each student's questions would differ from questions of all the others in class.

When electronically graded and returned, the scoring would then cover all the questions, and a wider range of ideas, thus providing the teacher immediate feedback on reaching specific academic objectives for the whole classroom. This process has been well researched and documented for about 35 years by the independent, National Assessment Of Educational Progress.

Should the teacher find these diagnostic quiz results unsatisfactory and desire a fresh approach to teaching the concept, a database of research-proven approaches, in lesson plan format should be available by electronic means. Over the years, educational research into successful teaching approaches has been supported by government grants and contracts, but remains hidden in some government file or on some professors' bio sheet. An entrepreneurial opportunity exists to validate and communicate these ideas; greatly assisting teachers through Internet downloads.

These are just a few ideas that should be available to help teachers reduce the errors in instructing America's uneducated youth. The service sector is always willing, capable and ready to fill this void, and to accomplish it competitively.

Computer-Aided Technology Use: With the familiarity of Internet use by today's educators, transition to this classroom measurement processes could occur with little training. In fact, the proliferation of software and hardware service could even assure test-item security for test manufacturers.

The service sector has a proven ability to meet this need quickly. Teachers would need log-in codes for program entry, classroom printers to download and print unique quizzes for students to answer, built in machine scoring capability to produce a classroom score and then destroy the paper tests, and database development to capture quiz and longer test results over a semester or year for teacher look-back and self-analysis.

This is just a sample of the aids a creative society could provide as assistance for our Nation's teachers, and result in improved student academic performance.

Decision Making: It goes without saying that individual leaders manage teachers' classrooms. Their success in fostering student academic achievements rests on their ability, training and support. Having immediate, professional feedback is much better than waiting a long time for "standardized test" results that come too late to practice remediation.

Merit Rewards: The basis for granting merit pay for exceptional performance is imbedded in the record electronically produced with each use of technology outlined in this article. It can be done. The private sector has shown the way!

How Satellite TV Systems Originated


What we know as satellite tv actually had its origins in the space race which began with the launching of the satellite Sputnik by the Russians in 1957. The first communication satellite was developed and launched by a consortium of business and government entities in 1963. It was known as Syncom II and achieved an orbit at 22,300 miles over the Atlantic. The first satellite communication was between a U.S. Navy ship in the harbor of Lagos, Nigeria and the U.S. Army located at the naval station at Lakehurst, New Jersey on July 26, 1963.

Telephone companies began using satellite communication for communicating as land based distribution methods became overloaded. Television began using satellites on March 1, 1978 when the Public Broadcasting Service (PBS) introduced Public Television Satellite Service. Broadcast networks adopted satellite communication as a distribution method from 1978 through 1984. As the use of satellites for communication and broadcast purposes increased, it became evident that everyone had the potential to receive satellite signals for free.

Direct to Home (DTH) satellite receivers were developed in the early 1980's. Rural areas thus gained the capacity to receive television programming that was not capable of being received by standard methods. With the development of television receive only (TVRO), broadcasters began to complain that reception of their signals were being either received illegally or pirated. The position of the Federal Communications Commission (FCC) was governed by its "open skies' policy. It was the FCC's position that users had as much right to receive satellite signals as broadcasters had the right to transmit them.

The broadcasters, in response to this government policy, began to use developed technologies which allowed them to scramble the signals they were broadcasting. Users, in turn, had to buy a decoder from a satellite program provider that packaged programs similar to the packages provided by cable systems. Ideas began to abound about the potential market for satellite television. The FCC, following the World Administrative Radio Conference of 1979, in 1980 established the plans and policy for a new service, direct broadcast satellite or DBS. This new service was to consist of a broadcast satellite in geostationary orbit, facilities for transmitting signals to the satellite and equipment needed by individuals to access the signals.

Early successful attempts to launch satellites for the mass consumer market were led by Japan and Hong Kong in 1986 and 1990, respectively. The first successful attempt by the United States was made by a group of major cable companies and was named Primestar. Next came Direct TV. Echostar Dish Network entered the market in the Spring of 1996 offering cheaper prices and forcing all of its competitors to do likewise.

How Albert Einstein Saw Things A Little Differently


Albert Einstein had just administered an examination to an advanced class of Physics students.

As he left the building, he was followed out by one of his teaching assistants.

“Excuse me, sir,” said the shy assistant, not quite sure how to tell the great man about his blunder.

“Yes?” said Einstein.

“Um, eh, it's about the test you just handed out.”

Einstein waited patiently.

“I'm not sure that you realize it, but this is the same test you gave out last year. In fact, it's identical.”

Einstein paused to think for a moment, then said, “Hmm, yes, it is the same test.”

The teaching assistant was now very agitated. “What should we do, sir?”

A slow smile spread over Einstein's face. “I don't think we need do anything. The answers have changed.”

And just as the answers in Physics change, so, too, do the answers to your problems change.

While to all appearances you may have the same tests given to you by life, the same recurring problem, consider the possibility that the person contemplating the problem has changed.

Time has passed; you've learned many things along the way.

Rather than keep on trying to force the same old solutions which didn't work before, it might be time to try something else, something that emerges from the new person that you've become.

The tests may be the same, but the answers have changed.

India to launch remote sensing satellite this month


BANGALORE, India (AFP) — India will later this month launch a remote sensing satellite equipped with high-resolution cameras and advanced scientific instruments, space agency officials said here.

Cartosat-2A, as the all-weather, reconnaissance satellite is called, will be used to plan urban and rural development projects. It can also be used for intelligence gathering, the officials said Friday.

"The tentative launch date is April 28," Indian Space Research Organisation chairman G. Madhavan Nair told reporters in Bangalore where the agency is based.

"The exact date and time will be finalised in a fortnight after factoring weather and other relevant data," he added.

Identical to the mapping satellite Cartosat-2, which was launched in January 2007, the 680-kilogram (1,500-pound) Cartosat-2A will be placed in a polar orbit at an altitude of 630 kilometres (391 miles).

The satellite will be launched by the Indian-developed rocket, the Polar Satellite Launch Vehicle, from the Sriharikota space station in southern India.

India started its space programme in 1963, and has since developed and put several of its own satellites into space. It has also designed and built launch rockets to reduce its dependence on overseas space agencies.

Space agency chairman Nair said the body has finalised a project report concerning a manned mission by 2014-15.

"The report is being submitted to the government for approval and budgetary allocation," he said. "The Space Commission, headed by Prime Minister Manmohan Singh, will meet next week or so to review the report and take a decision."

How to Find a Good Cheap Laptop


So you want a laptop but you don't have thousands of dollars to spend? Don't worry - there are plenty of ways to find a cheap laptop if you know where to look. Fortunately, laptop prices have actually come down quite a bit in recent years, so they aren't as expensive as they used to be. It's pretty easy to find laptop deals, especially if you wait for sales to pop up.

Cheap laptops are only worth the low price if they come with the features and specs you need in a computer. That means you should look for a high quality laptop at a reasonable price. Purchasing a laptop with the lowest price tag doesn't necessarily mean you're getting a good deal. If it doesn't perform well, it's not worth the money. The best laptop deals usually come from sales being held by an electronics store on laptops that you actually want.

If you don't have the patience (or the time) to keep your eyes constantly peeled for the next big sale, there are better ways to find cheap laptops. You can check out a used computer store to see if they have any good deals - used laptops are often only a few years old, still work well, and come for dramatically reduced prices. Sometimes, if you're lucky, you can find a second-hand laptop that's almost new at this kind of store.

Online shopping is another great way to find laptop deals. Online stores tend to offer lower prices, and when they have sales, you can find laptops for even less. Or, you can go the wholesale route and try to find the laptop you're looking for from a reputable wholesaler on the Internet. Finding cheap laptops isn't always easy, but it is possible. Once you start to know and understand the different sources that sell laptops, you'll become an expert at scouting out the rare finds.

Comparison shopping is also important if you want to find the best laptop deals out there. If you don't do some research and compare the prices on laptops in different stores, you won't know where the best deals are being offered. Again, this only applies to regular stores - if you want the lowest prices available for cheap laptops, you'll have to go directly to sources that the average consumer doesn't know about.

In addition to stores selling used laptops, you can search for online sites or stores selling refurbished laptops. Refurbished laptops are cheaper because they have a minor flaw, or have been returned by customers, and are being re-sold to the public. Stores can't sell the laptops for regular prices, so you can pick up some amazing laptop deals this way if you're willing to take a bit of a chance and deal with purchasing something that isn't in perfect condition. With this method you can buy cheap laptops that are the newest models.

Used laptop stores may offer slightly better deals, but you can't purchase brand new laptops at this type of store. Refurbished models, on the other hand, are new and up-to-date, except for the fact that the box may have already been opened.

How to Backup Your Computer if You Are Using Vista


With each version of the Windows operating systems the backup process has improved. In prior versions I relied on third party backup solutions. With the Vista operating system I found that the Backup program that comes with Vista is dependable, and there is no need to buy another backup program.

The above statements are true if you are backing up your data to a USB external drive. I have a 250Gb external drive and I backup my computer at least once a month. You can use DVDs, but you would need multiple DVDs.

If you have a home network you can also backup one computer to another. If you only have a wireless network I would not recommend it because it will be a very slow process.

To start the backup process click on the Start menu and select the All Programs button, then select the Accessories folder, then Systems Tools folder and click on Backup Status and Configuration menu option. You have three options here:

· Backup Files

· Restore Files

· Complete PC Backup

Backup Files is when you want to backup your data only. No programs or operating files will be backed up. This would be good if you have the Vista DVD and CDs for all of your application. You would then just have to re-install the operating system and the applications, then restore your data.

You can also set this for automatic and as long as the device that you back up to is connected, it will perform the backup automatically.

Restore Files if you needed to restore the files from step one discussed above. Restore Files will allow you to recover an individual file, or a backup made on another computer, or restore files made from this computer.

The Complete PC Backup will copy the entire contents of your hard drive. I usually backup my computer once a month using the data as the file name. You basically select the Complete PC Backup and click on Create a backup now. Make sure the hard drive you are backing up to is attached. It will take some time to backup your entire system, but I'd rather be safe than sorry.

Advanced Restore will allow you to transfer the entire contents of your backup to a new hard drive or computer. This is done through the Advanced Restore option after you click on the Restore Files button.

Backing up to another computer running Vista may cause problems with Windows authentication. If it is only the hard drive that is different, you will need to re-authenticate the computer, but it can be done in about ten minutes.

Everyone thinks that they are safe until their computer stops working. Hard drives fail on 35% of the computers within the first year. Why take a chance. Make sure you backup your computer today.

There are also on-line backup locations offered on the Internet. Some are inexpensive. If something happened to the backup device, you are still out of luck. Having an online backup might be the right solution because these companies have a lot of redundancy. Go to the newsletter section of my site where I recommend a vendor for backups.

Mysterious Meteorites Stymie Scientists


A pair of mysterious meteorites discovered in Antarctica is baffling scientists who are struggling to determine the origin of the space rocks. The meteorites, dubbed GRA 06128 and GRA 06129, were found in the Graves Nunataks region of Antarctica in 2006

The rocks were oddly rusty and salty and smelled like rotten eggs, its discoverers said.

Initially, a team at the University of New Mexico (UNM) caused a stir when its analysis hinted that the pair may hail from Venus or the moon.

But other teams then hurried to get pieces of the space rocks for analyses of their own—and for the most part, they disagree.

GRA 06128 looks like rocks retrieved from the lunar highlands by the Apollo 16 astronauts in 1972, but it contains much more sodium, research has shown.

The rock is also much older than the Venusian surface, according to the newer analysis, thereby eliminating that possibility.

The identity of the meteorites' source remains exciting and mysterious, said Allan Treiman, a scientist with the Lunar and Planetary Institute in Houston who led one of the recent investigations of the rocks.

"From what has been reported so far, it's pretty clear that the meteorite is not from the Earth, or the moon, or Venus, or any of the common sources of meteorites," he said. "It's much harder to know where it is from."

Both teams—along with three others—are presenting findings about the meteorites at the 39th Lunar and Planetary Science Conference in Houston this week.

Not of This World?

GRA 06128 and its mate are slab-shaped, gray rocks containing bits of black glass.

Mysterious Meteorites Stymie Scientists


One of the first teams to get a sample of the meteorites was led by UNM's Chip Shearer. The researchers analyzed chemical signatures called isotopes and initially determined that the meteorites came from Earth or the moon, a position they've since retooled.

"Although initial oxygen isotopic compositions are consistent with an origin in the Earth-Moon system, numerous observations appear to eliminate both bodies," Shearer and his team write in an abstract presented at this week's meeting.

Doug Rumble from the Carnegie Institution and his colleagues will also present an analysis of GRA 06128 and 06129 at the conference.

He said the New Mexico researchers initially studied a "tiny crumb that fell off the outside" of GRA 06129, but they didn't wash the outer layer to remove any Earthly weathering agents that might alter the findings.

"The UNM analytical results reflect only imperfectly the actual extraterrestrial composition of the meteorite, because UNM also analyzed rust that formed as the meteorite lay exposed to Earth's atmosphere," he said.

Rumble's own analysis puts the meteorites "right in the range of values expected for rare meteorites called brachinites," he said.

Brachinites are believed to be the remnants of planets that once orbited between Mars and Jupiter

"So now we are all meeting in Houston to hang our heads a little and admit to one another that maybe we were a little too hasty," Rumble said, "and got too excited over an unwashed meteorite."

Unsettled Debate David Kring, a visiting scientist at Houston's Lunar and Planetary Institute and a co-author on Treiman's paper, said there's still work to be done to nail down the exact nature of the meteorite pair.

The chemical and mineral compositions of the rocks are similar to brachinites and another type of meteorite called chondrites, he said.

Chondrites, leftovers from the formation of asteroids, are the most common meteorites. But the pair doesn't match either category exactly, Kring said.

The rocks are partially melted, which is not characteristic of chondrites.

And they contain high levels of the mineral feldspar, which is not typically associated with the short-lived planets between Mars and Jupiter.

"Thus there are two mysteries," Kring said. "What is the parent planet for the rock, and what type of geologic activity on that planet produced the unusual mineral assemblage?"

There is no shortage of new ideas to account for the disparity.

"My preferred working hypothesis is that [the meteorites] actually represent a piece of crust from an asteroidal body—the surface of another planet, if you like," offered James Day, a geologist at the University of Maryland.

Day has joined the other researchers at this week's meeting to puzzle over the rocks.

Treiman added that it would take a very large asteroid or a dwarf planet to cause the melting seen in the meteorites.

Whether or not its home is discovered, GRA 06128 is a "pretty puzzle, and will help us understand how asteroids form and how they evolve to become planets," he said.
