Rosetta: How we Landed on a Comet

This lecture will provide an update on the Rosetta mission after the lecture delivered at the Society in June 2014, prior to the landing. It will briefly summarize the objectives of the mission and the most important milestones of the 10 year flight, before concentrating on the most recent events: the arrival at the comet, the challenges of developing the comet model while orbiting it, and of course the landing. The exciting operations on the day of the landing and over the 2.5 days on the surface will be presented, together with an overview of the future activities of this extremely challenging and unique space mission.
