Astronauts make final spacewalk

Version 0 of 1.

Astronauts from the US space shuttle Discovery have made their third and final spacewalk, installing equipment on the International Space Station.

However, Nasa officials said one job had to be left undone after cables failed to connect.

Nasa flight director Heather Rarick said repairs to the connector would be attempted on a future mission, possibly Atlantis's flight in November.

The shuttle is due to leave on Tuesday and land back in Florida on Thursday.

Nasa officials said astronauts Danny Olivas and Christer Fuglesang completed their major objectives during the seven-hour spacewalk.

They unreeled 60ft (18m) of cable for a new room that will be added to the orbiting space station early next year.

They also connected two Global Positioning System antennas and replaced other electronic equipment in their second walk in three days.

Camera loose

However, near the end of the operation the pair had trouble hooking up one of the cable connectors to a panel on the space station.

The problem became worse when Christer Fuglesang's helmet camera came loose and flight controllers had difficulty watching him work.

"We thought you were doing tremendous acrobatics," Mission Control radioed.
