Definition
- The ROSETTA mission is an interplanetary mission whose main objectives are the rendezvous and in-situ measurements of the comet 67P/Churyumov-Gerasimenko, scheduled for 2014/2015. The spacecraft carries a Rosetta Lander, named Philae, to the nucleus and deploys it onto its surface. A brief description of the mission and its objectives can be found in [GLASSMEIERETAL2007A]. A detailed description of the mission analysis can be found in the ROSETTA User Manual [RO-DSS-MA-1001], and the flight Operations Plan [RO-ESC-PL-5000]. On its long way to the comet nucleus after a Launch by Ariane 5 P1+ in March 2004, the ROSETTA spacecraft orbited the Sun for one year until it returned to Earth for the first swing-by. The planet Mars was reached in February 2007, about 3 years after launch. In November 2007 a second Earth swing-by took place and a third one in November 2009. Two asteroid flybys (2867 Steins and 21 Lutetia) were performed on the way to the comet. These two asteroids had been selected at the Science Working Team meeting on 11th March 2004 among all the available candidate asteroids, depending on the scientific interest and the propellant required for the correction manoeuvre. Around the aphelion of its orbit, which is 5.3 AU from the Sun, the spacecraft has been in a spinning hibernation mode for about 2.5 years. Rosetta rendezvoused with comet 67P/Churyumov-Gerasimenko in August 2014. The Philae lander was deployed to the surface of the comet on 12 November 2014. The end of the nominal mission is planned in December 2015. The mission has been extended to 30th September 2016. (en)
