NASA satellite breaks up in plunge to Earth
CAPE CANAVERAL, Fla. (Reuters) - A six-tonnes NASA science satellite fell back to Earth, the U.S. space agency said on Saturday, but it was not yet known where the remains landed.
NASA said its decommissioned Upper Atmosphere Research Satellite was "passing over Canada and Africa as well as vast portions of the Pacific, Atlantic and Indian oceans" as it returned to Earth, and that "the precise re-entry time and location are not yet known with certainty."
The 20-year-old satellite, which took an unpredictable course as it tumbled through the upper atmosphere, fell to Earth sometime between 11:23 p.m EDT on Friday and 1:09 a.m. EDT on Saturday (0323 to 0509 GMT on Saturday), NASA said.
There were reports on Twitter of debris falling over Okotoks, a town south of Calgary in western Canada, most likely satellite remains.
Stretching 35 feet (10.6 metres) long and 15 feet (4.5 metres) in diameter, UARS was among the largest spacecraft to plummet uncontrollably through the atmosphere, although it is a slim cousin to NASA's 75-tonnes Skylab station, which crashed to Earth in 1979.
Russia's last space station, the 135-tonnes Mir, crashed into the Pacific Ocean in 2001, but it was a guided descent.
NASA now plans for the controlled re-entry of large spacecraft, but it did not when UARS was designed.
The 13,000-pound (5,897 kg) satellite was dispatched into orbit by a space shuttle crew in 1991 to study ozone and other chemicals in Earth's atmosphere. It completed its mission in 2005 and had been slowly losing altitude ever since, pulled by the planet's gravity.
Most of the spacecraft burned up during the fiery plunge through the atmosphere, but about 26 individual pieces, weighing a total of about 1,100 pounds (500 kg) could have survived the incineration.
The debris field spans about 500 miles (805 km), but exactly where it is located depends on when UARS descended.
With most of the planet covered in water and vast uninhabited deserts and other land directly beneath the satellite's flight path, the chance that someone would be hit by falling debris was 1-in-3,200, NASA said.
"The risk to public safety is very remote," it said.
The satellite flew over most of the planet, traveling between 57 degrees north and 57 degrees south of the equator.
UARS was one of about 20,000 pieces of space debris in orbit around Earth. Something the size of UARS falls back into the atmosphere about once a year.

World’s Best Photographers and their amazing shots
Its always a good feeling to see a nice picture taken from a right angle with the best camera available in market.But thats not the only prerequisite to capture a good photograph. Your involvement with the subject and the virtual development of the image in mind much before it is developed chemically or electronically is what makes the best photographers sets apart from others. For last few days I have been observing the work of some best known name in photography industry which prompted me to write this article.
Starting with the history and meaning of the word “photography” which comes from the Greek word ‘phos’ means “light” and ‘graphis’ means “representation by means of lines” or “drawing”, together which means “drawing with light.”
History of Photography goes back to the 1820s with the development of chemical photography.
The first permanent photograph was an image produced in 1825 by the French inventor Nicéphore Niépce
Though there were many world renowned photographers whose work was applauded and published for many decades
on various magazines,newspapers,internet and other platforms,there are certain legends like
David Seymour ,Henri Cartier-Bresson, Robert capa, Bruce Davidson, George Rodger,Eve Arnold and Raghu Rai whose names are unforgettable and sculptured in golden words in the world of photography.
They were not only the best photographers but were also the founding members of Magnum Photos,a cooperative organization
founded in 1947 owned and administered entirely by its member with offices in New York, Paris, London and Tokyo for showcasing classic and unique work of world’s best photographer.
The first name which comes to my mind is Henri Cartier-Bresson who was born in 1908 and was a French photographer considered to be the father of modern photojournalism,an early adopter of 35 mm format, and the master of candid photography. After trying his hand in music and painting he finally settled with photography as his last and only obsession.He joined the French Army as a Corporal in the Film and Photo unit when World War II broke out in September 1939.In spring 1947, Cartier-Bresson, with Robert Capa, David Seymour and George Rodger founded Magnum Photos.
He achieved international recognition for his coverage of Gandhi’s funeral in India in 1948 and the last (1949) stage of the Chinese Civil War.He died in Aug 2004.
David Seymour born to jewish parents in 1911 covered Spanish civil war and other European events.In 1947 he founded Magnum.In 1954 after Robert capa’s death he became president of magnum.while covering the 1956 Suez war he was killed by egyptain machine gun fire.
George Rodger was a brit journo .He was the first photographer to enter concentration (death) camps at Bergen-Belsen , a Nazi
concentration camp in Germany during second world war in 1945.His photographs of the few survivors and piles of dead human body were published in Life and time magazines and were highly influential in showing the reality of the death camps.
After founding magnum he worked as a freelance photographer taking pictures of people,nature and landscape which were later published in national geographic magazine.
Eve Arnold was the first female member of magnum and changed the myth that women can’t be good photgraphers and they can only pose for photographs.she was born in Philadelphia.She was best known for her intimate image of actress Marilyn monroe on the sets of Monroe’s last film,The Misfits.Currently she lives in Britain.
Raghu Rai born in 1942 is an Indian photographer and photojournalist who initially worked with The Statesman.
In 1976,he left the paper and became a freelance photographer. From 1982 up until 1992, Rai was the director of photography for India Today.He was the only Indian photographer to be a member of Magnum photos and joined it as correspondent in 1977.
Rai was awarded the Padmashree in 1971, one of India’s highest civilian awards ever given to a photographer. In 1992, his National Geographic cover story “Human Management of Wildlife in India” won him widespread critical acclaim for the piece.
There are so many other photographers (though all the names cannot be mentioned here)
around the world who are working round the clock taking best shots for all our feel-good factor.

India's F1 track ready for 2011
Speaking of whether or not the circuit would be finished in time was Samir Gaur, managing director of construction company JPSK Sports: "The progress is very nice. I'm absolutely, absolutely confident that the track will be ready in 2011," he toldReuters.Constructors of the New Delhi circuit have confirmed that the venue is making progress, and will be able to debut on the Formula One calendar in two years' time. India is one of a number of countries scheduled to host its first Grand Prix in coming seasons, starting with Abu Dhabi at the end of 2009.
Originally planned to debut next year, however, the race's slot was moved by a year due to the international credit crunch and a subsequent decision by Formula One Management's Bernie Ecclestone.
Although the country is yet to host a Formula One Grand Prix, the first Indian team appeared in 2008 after Kingfisher's Vijay Mallya acquired the Dutch Spyker outfit. There are no worries over the attendance of the race either, as India is the world's second most populated country, after China.
