It is projected that the Hubble Space Telescope will be in service up to the year 2010. Discussion has begun if at that time they should just burn it up, or should they bring it back and put it on display. It is a question if it is worth the cost and the risk to human life to try and save the hubble space ship. http://www.berkeley.edu/news/berkeleyan/2003/08/27_hub.shtml
