ESA cheers on NASA's Deep Impact success [ESA] - "We are proud to be contributing to this campaign with some of our best sky-watchers - our Rosetta comet-chaser spacecraft, the XMM-Newton X-ray observatory, as well as Hubble Space Telescope (which we share with NASA) - and with ESA's Optical Ground Station in the Canary Islands. The results are going to be a terrific help in planning Rosetta's comet landing a decade from now." - David Southwood, European Space Agency's Director of Science
