Uppsala researchers study the transformation of a comet
In July, Rosetta is expected to send the first images of comet 67P/Churyumov-Gerasimenko's nucleus, as seen from a large distance. The space probe will enter an orbit around the comet nucleus in August, where it will remain for one and a half years while the comet approaches the sun. The camera on board has been built by a European consortium where Sweden has contributed several of the lens's filters. One of the leading researchers on the camera team, Hans Rickman at the Department of Physics and Astronomy, has also contributed to the selection of filters and overseen their manufacturing in Sweden. He and his Uppsala colleague Björn Davidsson will study the images to find out more about the comet's composition and what happens when the comet is gasified.
