Rosetta comet-chasing spacecraft wakes up – as it happened

The European Space Agency has received a signal from its comet-chasing spacecraft Rosetta confirming that it is alive and slowly warming up in deep space, after nearly three years out of contact with Earth

A Long and Winding Road: Cassini Celebrates 15 Years - Since launching on Oct. 15, 1997, the spacecraft has logged more than 3.8 billion miles (6.1 billion kilometers) of exploration - enough to circle Earth more than 152,000 times. After flying by Venus twice, Earth, and then Jupiter on its way to Saturn, Cassini pulled into orbit around the ringed planet in 2004 and has been spending its last eight years weaving around Saturn, its glittering rings and intriguing moons.

NASA/JPL Deep Space Network. There are three telescopes about 120 degrees in longitude apart. The strategic placement of these sites permits constant communication with spacecraft as our planet rotates – before a distant spacecraft sinks below the horizon at one DSN site, another site can pick up the signal and carry on communicating.
