The Rosetta mission, being undertaken by ESA, aims to research the history of how our Solar System was formed by investigating one of the oldest and most primordial of heavenly bodies, a comet. The mission consists of one orbiter and the Philae lander. DLR played a major role in building the lander and runs the lander control centre which is preparing for and overseeing the difficult task of landing on the comet, a feat never before accomplished.
More than two and a half years – this is how long the Philae lander has been hibernating while travelling through space on board the European Space Agency ESA Rosetta spacecraft. On 28 March, the lander was successfully reactivated and broke its planned radio silence by sending data to Earth from a distance of about 655 million kilometres.
A rocket launch in March 2004, multiple swing-bys past Earth and Mars, high-speed fly-bys of asteroids Šteins and Lutetia – after all this, the Philae lander on board ESA's Rosetta spacecraft, which is en route to Comet 67P/Churyumov-Gerasimenko, is in good shape.
