S134-E-008468(22 May 2011) --- The feet and lower legs of NASA astronaut Michael Fincke in the airlock prior to the STS-134 mission’s second space walk, and Fincke’s first for the flight so far. A little later, astronauts Fincke and Andrew Feustel (left side of the frame) both mission specialists, coordinated their shared activity with NASA astronaut Greg Chamitoff (out of frame), who stayed in communication with the pair and with Mission Control Center in Houston from the shirt sleeve environment inside the ISS.
