On May 25, 2011 American astronauts of the STS-134 crew Andrew Feustel and Michael Fincke performed a six-hour, 54-minute spacewalk.

The space walkers completed all planned tasks: installing cables to increase redundancy for the power system on the Russian segment of the station; completing the external wireless antenna system and installing a power and data grapple fixture to the "Zarya” module. The fixture will allow the station's robotic arm to "walk" to the Russian segment, extending its reach by using that grapple fixture as a base.
This was the third of the four STS-134 spacewalks. It was the 247th spacewalk conducted by U.S. astronauts, the 117th from space station airlocks and the 158th in support of space station assembly and maintenance.
