Astronauts from the US space shuttle Discovery late Saturday concluded a third and final spacewalk of their mission, installing new equipment on the International Space Station, but failing to connect some of the cables.
NASA astronaut Danny Olivas and his European Space Agency collegue Christer Fuglesang of Sweden concluded the more than seven-hour walk at 11:40 pm (0340 GMT Sunday), the US National Aeronautics and Space Administration said.
According to the announcement, they completed their major objectives, but not all of them.
The spacewalkers deployed a new payload attachment system, replaced a failed rate gyro assembly, installed two GPS antennae and did some work to prepare for the installation of the Node 3 "Tranquility" module next year.
"During connection of one of two sets of avionics cables for Node 3, one of the connectors could not be mated," NASA said in a statement. "This cable and connector were wrapped in a protective sleeve and safed. All other cables were mated successfully."
