Rosetta is a cornerstone mission to chase, go into orbit around, and land on a comet. It is studying the Jupiter-family comet 67P/Churyumov-Gerasimenko with a combination of remote sensing and in situ measurements. The spacecraft arrived at the comet on 6 August 2014 following a 10-year journey through the Solar System. Between August and November, the spacecraft has been orbiting the comet and gathering data to characterise the environment and the comet nucleus. On 12 November 2014, Rosetta’s lander Philae will be deployed to the surface. Philae carries a suite of instruments for imaging and sampling the comet nucleus. The Rosetta orbiter will track the comet through perihelion (August 2015), examining its behaviour before, during and after.

[SIC]: I saw a pronunciation guide for Philae that said “fee-lay.” This is wrong. The pronunciation rhymes with eye-lee, or “highly.” Whenever you see ae, it rhymes with ee as in leek. For example, Caesar. And yes, the UNIX-famous word “daemon” is pronounced precisely and exactly like demon. Other pronunciations are wrong. (Merriam-Webster, Wikipedia).
