S134-E-008465 (22 May 2011) --- Wearing an Extravehicular Mobility Unit spacesuit, NASA astronauts Andrew Feustel and Michael Fincke (out frame), both STS-134 mission specialists, get prepared for the mission's second spacewalk onboard the International Space Station (ISS). Once outside the orbiting complex, Feustel and Fincke 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.
