CAPE CANAVERAL (AP) - Astronauts are about to touch the Hubble Space Telescope for the last time.
Atlantis spacewalkers John Grunsfeld and Andrew Feustel (FOY-stahl) will leave the space shuttle Atlantis Monday morning for their mission's fifth and final spacewalk.
This is also the fifth and final repair mission for the 19-year-old telescope.
The shuttle will release Hubble on Tuesday. NASA hopes these repairs will buy Hubble five to 10 more years of life. After that, a robot will steer Hubble back into Earth's atmosphere and toward a watery grave.
The astronauts Monday will replace a couple batteries, a sensor and some insulation. They will try to make insulation repairs that were supposed to be completed Sunday, but couldn't get done because of problems with a balky bolt.
