The Hubble Space Telescope now has a more commanding view of the cosmos. Astronauts John Grunsfeld and Andrew Feustel installed a new high-tech instrument on Saturday.

The space-suited repairmen then pulled off their toughest job yet --- fixing a broken camera. It was the most intricate work ever performed because the camera was not designed to be handled by astronauts wearing thick, stiff gloves.

NASA considered this repair job -- and one set for Sunday on another failed science instrument -- to be the most delicate and difficult ever attempted in orbit. If all goes well, the fifth and final space walk is set for Monday.
