Final Spacewalk for STS-134
NASA astronaut Michael Fincke worked outside the station during the fourth and final spacewalk of the STS-134 mission, which lasted more than 7 hours. Fincke and fellow astronaut Greg Chamitoff completed the primary objectives for the spacewalk, including stowing the 50-foot-long boom and adding a power and data grapple fixture to make it the Enhanced International Space Station Boom Assembly, available to extend the reach of the space station's robotic arm.
