Stock Photo - With various components of the International Space Station (ISS) in the view, NASA astronaut Michael Fincke is pictured during the STS-134 mission's third space walk. Astronauts Fincke and Andrew Feustel (barely visible on left side of frame with red stripes on his suit), both mission specialists, coordinated their shared activity with NASA astronaut Greg Chamitoff (out of frame). Chamitoff, who worked outside the orbital complex and the first of four scheduled space walks, stayed in communication with the pair and with Mission Control Center in Houston from the shirt sleeve environment inside the ISS. Part of the ISS robotic system is also visible.
