We all know Hubble telescope. NASA is going to carry out shuttle servicing mission.Without servicing, the observatory is not expected to last more than two or three years. Its batteries and gyroscopes, which are used to point the telescope, are degrading and they will now be replaced.There is a lot of cost associated with it and there are contradicting views regarding the future of this telescope.What do you guys think? Shold Hubble telescope get upgrade? Does anybody have insight into this?
