Quentin Cooper reports on the final Hubble Space Telescope Servicing Mission. Astronaut Jeff Hoffman shares his experience of installing the camera that is being replaced and Steve Beckwith, former director of the Space Telescope Science Institute, explains the long struggle to get the mission approved. Some 50 years after thalidomide caused so many deformed births, scientists in Aberdeen describe their work which purports to explain, for the first time, exactly why it does what it does. Quentin speaks to the CERN scientist who is thought to be the inspiration behind the film and novel Angels and Demons.
