Canadian Astronaut Dave Williams Does Second Spacewalk Monday

Aug 13, 01:05 PM

Current Headlines: HOUSTON (CP) - Canadian astronaut Dave Williams has started his second spacewalk to replace equipment on the International Space Station.

Williams and American astronaut Rick Mastracchio floated out of the space station's airlock just after 11:30 a.m. ET for their second spacewalk in three days. The pair will remove a gyroscope that failed in October and replace it with one that the shuttle Endeavour carried to the station.

Williams is set to go on a third spacewalk on Friday, which would make the Saskatoon-born and Montreal-raised astronaut the Canadian with the most time spent floating freely in space.

And Williams' name has been mentioned if NASA decides there is a need to repair a gouge on the shuttle's underside.

A chunk of insulating foam hit the shuttle at liftoff last week in an unlucky ricochet off the fuel tank and carved out the gouge.

During Williams and Mastracchio's first spacewalk on Saturday, they installed a new beam to the International Space Station.

Endeavour has been docked there since Friday.

It will remain there until Aug. 20 for a record 10-day stay, three days more than originally scheduled.
