Rosetta: The comet chaser

The Rosetta spacecraft was launched in 2004 and arrived at Comet 67P/Churyumov-Gerasimenko on August 6, 2014, becoming the first probe to rendezvous with a comet. On November 12, Rosetta deployed its Philae lander to the comet's surface -- another first. Rosetta will continue following the comet as it makes it way around the sun. Rosetta is a European Space Agency mission with contributions from NASA.
