Eyeing a post-Hubble Universe

BBC NEWS discusses the future without the Hubble Space Telescope. The Hubble was launched in 1990, and later had its optics repaired, and since then has sent back some of the most amazing images to Earth. It has always been planned that Hubble would have a limited life, ending around 2010, with the replacement James Webb telescope to be launched in 2011. Many scientists, however, argue against ending Hubbles life.
