Join us for a live webcast with senior scientist Paul Doherty to discuss breaking news about the Rosetta Mission! The European Space Agency’s Rosetta mission deployed its lander, Philae, to the surface of Comet 67P/Churyumov–Gerasimenko on November 12. 2014. Philae’s landing site, currently known as Site J, is located on the smaller of the comet’s two ‘lobes’, with a backup site on the larger lobe. The sites were selected just six weeks after Rosetta arrived at the comet on August 6, following its 10-year journey through the Solar System.
