Spacewalking astronauts gave the Hubble Space Telescope a more commanding view of the cosmos by installing a new high-tech instrument Saturday, then pulled off their toughest job yet: fixing a broken camera.
It was the third spacewalk in as many days for the shuttle Atlantis crew and the most intricate ever performed because of the camera repairs. Astronauts had never before tried to take apart a science instrument at the 19-year-old observatory.
