Rosetta arrives at comet

Launched in 2004, the Rosetta spacecraft has finally arrived at comet 67P/Churyumov-Gerasimenko. It will be the “first mission in history to rendezvous with a comet, escort it as it orbits the Sun, and deploy a lander to its surface”. Follow the event live at:
Rosetta spacecraft 5 days from arrival at comet

As the ESA’s Rosetta spacecraft closes to within 1000 km of Comet 67P/Churyumov-Gerasimenko, the Rosetta science team has released a new image and made the first temperature measurements of the comet’s core. Rosetta Website – http://sci.esa.int/rosetta/
