Hubble to be repaired

NASA has big plans to extend the life of the Hubble Space Telescope. NASA announced plans for a shuttle mission to repair the aging telescope in 2008. The announcement reverses an earlier decision against a Hubble mission because of safety concerns. The $900 million mission will be carried out in five spacewalks from space shuttle Discovery. During the spacewalks, astronauts will add new camera instruments, upgrade aging batteries and repair and add new equipment. The mission should keep 16-year-old Hubble working until about 2013. Without a repair mission to Hubble, the space telescope would likely stop working in 2009 or 2010.
