When I see things like this, my first reaction is, oh another internet hoax. It's not. The interesting contradiction is that it will cost about the same to run a service operation for new batteries and gyroscopes as it will to biuld a rocket that will guide it to destruction.

January 18, 2004 | On Friday, January 16th, NASA administrator Sean O'Keefe announced that there will be no more shuttle missions to service the Hubble Space Telescope. The agency will operate the orbiting observatory only until it succumbs to a critical system failure, which could happen as soon as today or as late as several years from now. Either way, Hubble's clock is running down.
