Space Shuttle Endeavour docked with the International Space Station (ISS) at 12:14 CEST on 18 May 2011. The hatches between the two spacecraft were opened at 13:38 CEST and the STS-134 crew entered the Station for the first time a short while later. After welcoming them on board, the Shuttle crew were given a guided tour of the ISS to help them get their bearings of the orbital outpost. In this picture Expedition 27 crewmember and ESA astronaut Paolo Nespoli is seen starting a tour with some of the STS-134 crew, including ESA astronaut Roberto Vittori (to Nespoli's left).
