The beleagured space telescope we all know and love has suffered another failure of its main camera, the second such fault this year. The other instruments are working fine, and are shouldering the workload as best they can, but Hubble needs some serious repair work to extend its working life. NASA still won’t commit to doing a maintenance visit, however, which may mean we have to wait for the James Webb telescope to replace it, set to be launched in 2011.
