It’s been an extraordinary year for the Rosetta comet mission since Philae landed on the surface of comet 67P/Churyumov-Gerasimenko on 12 November 2014. Continual data from the orbiter, together with information collected over several days from the lander, is providing a comprehensive picture of a remnant from our Solar System.

This film covers the most recent science news from the Rosetta mission, as well as selected scientific highlights from the last year. It includes the comet’s unusual surface terrace structure, its formation from two colliding objects producing the unusual rubber duck shape, how water is transported from inside the comet towards the surface, and the surprising detection of molecular oxygen - familiar on Earth but not on a comet.

It includes filming at the European Space Astronomy Centre at Cologne, Germany; the ROSINA laboratory at the University of Bern in Switzerland; and interviews on both the A-roll and B-roll with Kathrin Altwegg, ROSINA Principal Investigator, ESA; Patrick Martin, Rosetta mission manager, ESA; Fabrizio Capaccioni, VIRTIS Principal Investigator, ESA.
