INTERNATIONAL SPACE STATION -- Shuttle Discovery's astronauts have breezed through their third and final spacewalk.
They replaced an empty gas tank at the international space station and collected a sample of dusty debris.
Spacewalkers Michael Fossum and Ronald Garan Junior wrapped up their work so quickly, Mission Control threw in some extra chores.

The highlight of the six-and-a-half-hour spacewalk for Garan was a long ride on the space station's robot arm that swung him 80 feet out from the orbiting complex. He carried an empty nitrogen gas tank from one side of the station to the other, then returned with a full tank and plugged it in for use in the coolant system.
Discovery and its crew have two more days at the space station, before leaving Wednesday.
