An Ariane 5-ECA heavy rocket lifted off from Europe's space base on French Guiana Wednesday and put into orbit the South Korean Koreasat 6 and Spanish Hispasat 1E telecommunications satellites. The launch from Europe's Spaceport in Kourou was the Ariane 5 launcher's sixth and last mission of the year. Lift-off was delayed by about 24 hours because of high winds.
"It is the 41st successful mission in a row of Ariane 5. In 2010 we launched 12 satellites from a world total of 20." said Arianespace chief Jean-Yves Le Gall.
ESA's GIOVE-A satellite - the first prototype of Europe's Galileo satellite navigation system - is still working well after five long years in space. It was launched on 28 December 2005 from Kazakhstan.
On 27 April 2008 GIOVE-B joined older brother, equipped with an ultra-precise passive hydrogen maser design.
"Both satellites had a design lifetime of 27 months each", said Valter Alpe, managing GIOVE activities for ESA. "It is a pleasent surprise, therefore, to have GIOVE-A still fully operational after 60 months in orbit. GIOVE-B, meanwhile, is showing no sign of problems after 33 months in space."
True life story of Carrie Anderson. When she was little girl she dreamed of becoming an astronomer. Now, as a space scientist at NASA GODDARD Space Flight Center, Carrie studies the atmosphere on Titan: one of Saturn's moons, second largest moon in the solar system, just behind moon Ganymede, Jupiter's follower. Let's see what Carrie want us to hear..
WISE - Wide-field Infrared Survey Explorer saw a circular rainbow around an exploded star. When massive stars die, they explode in BIG blasts, called supernovae, which send out shock waves. The shock waves sweep up and heat surrounding gas and dust, creating supernova remnants like the one pictured here. The supernova in IC 433 happened somewhere between 5000 and 10000 years ago. More about this topic on www.nasa.gov.

Let's first see how LOLA (Lunar Orbiter Laser Altimeter) works. LOLA sends a pattern of five laser pulses to the lunar surface, and computes distance and elevation by measuring how long takes for the pulses to return. Credit: NASA/Goddard/Chris Meaney
