Two astronauts successfully completed the final planned spacewalk of the space shuttle era on Friday. Mike Fincke and Greg Chamitoff spent seven hours and 24 minutes outside the International Space Station on Friday, wrapping up the fourth and final spacewalk of the STS-134 mission at 7:39 am EDT (1139 GMT) Friday. The two helped install a sensor boom originally developed to scan the orbiter for damage while in orbit on the station, where it will remain to serve as an instrument extension of the station's Canadarm2. The two also performed work on the Dextre robotic manipulator on the station. During the EVA the astronauts passed the 1,000-hour mark in space station spacewalks for assembly and maintenance. The spacewalk, the last of the STS-134 mission, is also the last expected to be associated with a shuttle mission as none are planned for the final shuttle mission in July, STS-135.
