On 15 September the Rosetta mission will announce the primary and back up landing sites for comet 67P/Churyumov-Gerasimenko. <br /> <br />This video reviews the five shortlisted landing sites, why they were selected and how the comet’s unusual ‘duck’ shape affected the choice. <br /> <br />The Rosetta orbiter has been studying the comet since May and choosing the right place to land is crucial in order to examine the comet further. The orbiter’s data – together with that from the Philae lander – will provide unprecedented insights into our solar system. <br /> <br />The film also covers the preparation by scientists, members of the mission control team at the European Space Operations Centre at Darmstadt, in Germany, and the challenges ahead.
