Galileo will use the most accurate atomic clock in space to provide the most accurate positioning services. In fact time is the key for satellite navigation systems. The launch of the first pair of Galileo satellites, set for October 20, will open the road for Europe's satellite navigation programme. Another In-orbit Validation pair will be lofted next year and the full constellation will become fully operational with a constellation of 30 spacecraft. Their technologies have already been demonstrated with two precursor satellites GIOVE-A & B. At the heart of each Galileo satellite are four atomic clocks which will ensure that users on Earth to know their position to within a metre. These ultra-precise clocks will all beat in rhythm, rigorously synchronized with the ground network of control stations. That is why Galileo has been described as 'one vast space clock'.

Earth Sized Tornado Spins On Sun's Surface Feb-2012.mpg
Vast solar tornado spins on the sun A tremendous tornado whirling across the surface of the sun was captured by a NASA satellite recently -- an amazing wonder of the solar system that may be as big as the Earth itself. The video was recorded by the Solar Dynamics Observatory (SDO), a sun-watching satellite that has transmitted a series of stunning photos of solar flares in recent months. The new video shows darker, cooler plasma shifting back and forth above the sun's surface over the span of nearly 30 hours stretching from Feb. 7 to Feb. 8. And the giant tornado may be as large as the Earth itself, with gusts of up to 300,000 mph, explained Terry Kucera, deputy SOHO project scientist and a solar physicist with NASA's Goddard Space Flight Center.
