ESA Rosetta
The ESA Rosetta spacecraft launched on March 2nd, 2004.
After a journey of over 6 billion km, Rosetta has finally arrived today at comet 67P/Churyumov–Gerasimenko. Along its journey, Rosetta completed fly-bys of Mars in 2007, asteroid 2867 Steins in 2008, and asteroid 21 Lutetia in 2010.
This is the first spacecraft to ever rendezvous with a comet.
In November 2014, Rosetta will deploy the Philae lander which will land on the surface of the comet.
Rosetta's mission will last for 17 months until December 2015.
