Astronauts make 4th, final spacewalk of mission
Wednesday, May 25, 2011
CAPE CANAVERAL, Fla. (AP) -- Two astronauts are making the fourth and final spacewalk of NASA's next-to-last space shuttle mission.
Endeavour astronauts Mike Fincke and Gregory Chamitoff floated out of the International Space Station early Friday to install a 50-foot boom.
They are the last shuttle crew members to perform a spacewalk. All future spacewalks will be performed by full-time space station residents.
The Endeavour astronauts used the laser-tipped pole Thursday to survey their ship one last time in orbit. They attached it to the end of a robot arm to check for micrometeorite damage. NASA expects to finish reviewing the 3-D images Friday.
The boom will remain permanently at the space station and assist with future repairs.
