Highlights GPS based on seven satellites, last of which was launched in April Atomic clock on one satellite stops working, making it invisible Other satellites still transmitting crucial navigational information India's home-made navigational system, named NAVIC by Prime Minister Narendra Modi, has developed a technical problem. One of the seven satellites in the Indian version of the American Global Positioning System or GPS is malfunctioning, as a result of which it's not visible. The seven satellites together provide strategic services, the last of them was launched in April last year. Despite the flaw, the Indian Regional Navigation Satellite System is still functional.

Atomic clocks are used for precision time-keeping; India had imported these for the constellation of seven satellit...

Thomas Edison Born : 1847 - 1931 He was born in Milan, Ohio in America. When he was seven, his teacher lost patience with his persistent questioning and selfish behaviour and suggested that Thomas might be mentally unstable. (Today, he would probably have been labelled as having attention deficit syndrome and given Ritalin). His mother was not happy with this and started teaching him from home instead of sending him to school. He managed to read everything in his local library including some really difficult books like Isaac Newton's "Principia", which is so difficult, not many adults have ever read it. He started to lose his hearing about this time, and became almost totally deaf. He felt this helped him concentrate on his inventions, and when he was offered an operation to help him hear again later in life, he refused to have it done. Thomas Edison died On Oct. 18th, 1931 in New Jersey at age 84. On the evening of the day that he was laid to rest, people al...

However, till now, they have flown in the space just once. As part of the secret mission, the first flight was launched on the Vandenberg Air Force Base in California and the other one is scheduled to be launched in the month of October. The mini shuttle was first launched in 2010. It has been informed that in the month of October the Air Force’s mysterious X-37B space plane will be launched. The mini shuttle will blast into space from Cape Canaveral Air Force Station in Florida. Air Force Spokesperson, Major Tracy Bunko said, “Preparations for launch at Cape Canaveral have begun”. It has come to light that about four months ago, the X-37B space plane returned from its secret mission after spending 469 days in orbit. It is hoped that this time as well the space plane will land safely back to the Earth. ...

A team of astronomers at the Smithsonian Astrophysical Observatory has done something never ever done before, despite many big achievements, a recent report has revealed. While in 1781, Charles Messier had discovered a galaxy dubbed M87, though not sure if it was a galaxy. It is being said that the team has measured the radius of the black hole at the center of the galaxy. The radius of the supermassive hole was measured with the help of the Event Horizon Telescope, the report finds. It has been told that the same was initially taken by the team so as to observe the M87 galaxy. It is being said that the black hole is some 6 billion times massive as compared to the Sun. As per the findings, the telescope is a chain of different radio telescopes in California, Arizona and Hawaii. However, a picture of jets that were ejected from M87's black hole was captured by the telescope previously also. The same has this time helped in identifying that the black hole is 50 million light...

Albert Einstein was born as the first child of the Jewish couple Hermann and Pauline Einstein, nee Koch, in Ulm on March 14, 1879 . When Albert’s grandmother saw him for the first time she is said to have cried continuously: "Much too thick! Much too thick!" But despite all fear the development of young Albert was a normal one. In November 1881 Albert’s sister Maria – called  Maja  – was born. A short time later the Einstein family went to Munich where Albert first attended elementary school and subsequently Luitpold grammar school. He was an "average" pupil but already very early interested in science and mathematics. He did not like lessons in grammar school as they were held with strict discipline and as he was forced to learn. When he turned 15 he left school without any degree and followed his family to Milan. To make up for the missed degree he attended school in Aarau (Switzerland) from 1895 to 1896 when he successfully took his A-levels and b...

So you think you know Albert Einstein: the absent-minded genius who gave us the theory of relativity (two of them, in fact, special theory and general theory of relativity), but did you know that Einstein was born with such a large head that his mother thought he was deformed? Or that Einstein had a secret child before he was married? Read on for more obscure facts about the life of the world’s smartest genius: 1. Einstein Was a Fat Baby with Large Head When Albert’s mother, Pauline Einstein gave birth to him, she thought that Einstein's head was so big and misshapen that he was deformed! As the back of the head seemed much too big, the family initially considered a monstrosity. The physician, however, was able to calm them down and some weeks later the shape of the head was normal. When Albert's grandmother saw him for the first time she is reported to have muttered continuously "Much too fat, much too fat!" Contrasting all apprehensions Albert grew and de...
