On 12 November 2014, ESA's Rosetta mission soft-landed its Philae probe on comet 67P/Churyumov-Gerasimenko, the first time in history that such an extraordinary feat has been achieved. During the following phase of the mission, Rosetta will accompany the comet through perihelion (August 2015) until the nominal end of the mission. On its 10 year journey towards comet 67P/Churyumov-Gerasimenko, the spacecraft has passed by two asteroids: 2867 Steins (in 2008) and 21 Lutetia (in 2010). The spacecraft entered deep-space hibernation mode in June 2011, and 'woke up' on 20 January 2014.
The SD2 instrument onboard the Philae lander has been operated under the scientific responsibility of Politecnico di Milano.
