Live event: Rosetta arrives at Comet 67P/Churyumov–Gerasimenko

On August 6, 2014, after a decade-long journey through space, ESA’s comet chaser "Rosetta" will become the first spacecraft in history to rendezvous with a comet. Rosetta will also be the first mission in history to escort a comet as it or

ESA’s comet chaser Rosetta has made its first temperature measurements of its target comet, 67P/Churyumov–Gerasimenko, and found that it is too hot to be covered in ice and must instead have a dark, dusty crust.The observations of the comet we

As comet-chaser Rosetta approached its target to roughly 2 million km in early May, images captured by OSIRIS clearly showed that the comet has already developed 1 300 km long coma. This onset of activity offers scientists the opportun

Rosetta, a unique ESA's comet-hunting spacecraft, captured first images of its destination comet 67P/Churyumov–Gerasimenko on March 20, 2014. If everything goes by the plan this solar-powered spacecraft will become the first space

Rosetta wakes up from deep space hibernation

After 31 months of deep space hibernation ESA's comet chaser "Rosetta" has woken up and contacted mission control today. The signal was received by NASA’s Goldstone ground station in California at 18:18 UTC, during the first window of oppor
