Professor James Hough talked on “Comets and the Rosetta Mission”. Focussing on the story of ESA’s Rosetta 10 year journey, which was the first to rendezvous with a comet, the first to follow a comet on its orbit around the Sun, and the first to deploy a lander to a comet’s surface with Philae lander. James then went on to discuss the mission’s experiments into whether comets and/or asteroids could have delivered water to the Earth and also had a part to play in the evolution of life by the presence of amino acids such as valie, tryptophan, leucine etc., the building blocks of proteins.
