CAPE CANAVERAL, Fla. – At the Shuttle Landing Facility, STS-127 Mission Specialist Dave Wolf is greeted by the media and others on hand to welcome the STS-127 crew to NASA's Kennedy Space Center in Florida. Wolf and the other members of the crew arrived from Houston aboard a Shuttle Training Aircraft to get ready for launch on space shuttle Endeavour on June 13.  Wolf, a medical doctor, spent 128 days on the Russian space station Mir and is making his fourth shuttle flight.  The STS-127 mission is the final of three flights dedicated to the assembly of the Japan Aerospace Exploration Agency's Kibo laboratory complex on the International Space Station.  Endeavour will deliver the Japanese Experiment Module's Exposed Facility, or JEM-EF, and the Experiment Logistics Module-Exposed Section, or ELM-ES, to the space station on STS-127.
