An RAS Specialist Discussion Meeting organised by Dr Mark Price (Kent), Dr Stephen Lowry (Kent), Professor Mark Burchell (Kent), Dr Penelope Wozniakiewicz (NHM), and Dr Kathryn McDermott (Kent)* *Contact: m.j.burchell_AT_kent.ac.uk Studies of comets have been dramatically changed by space missions to several comets. In the last decade the NASA Stardust spacecraft returned samples from comet 81P/Wild 2 and flew past comet Tempel 1 which had also been visited by the NASA Deep Impact Mission. This year the European Space Agency spacecraft Rosetta will rendezvous with comet 67P/ Churyumov-Gerasimenko and will then place a lander on its surface – the first soft landing on a comet. In addition, ground based astronomers and the general public will have been able to see comet 2012 S1 (ISON) loom large in the night sky during the end of 2013 and early 2014. This discussion meeting aims to bring together all those interested in cometary science; bridging the gap between those working on different space missions, as well as between those working on missions, modellers and observational astronomers. Talks are expected to include latest results from 81P/Wild 2, the status of, and expectations for, Rosetta as well as on news of comet ISON.
