European Space Agency astronaut Thomas Reiter (seated), returning from a 6-month stay on the International Space Station, visits with colleagues in the crew quarters at Kennedy Space Center. Reiter returned to Earth with the STS-116 crew aboard Space Shuttle Discovery. Landing took place on Runway 15 at NASA Kennedy Space Center's Shuttle Landing Facility as the sun set on the shortest day of the year. During the STS-116 mission, three spacewalks attached the P5 integrated truss structure to the station, and completed the rewiring of the orbiting laboratory's power system. A fourth spacewalk retracted a stubborn solar array. Main gear touchdown was at 5:32 p.m. EST. Nose gear touchdown was at 5:32:12 p.m. and wheel stop was at 5:32:52 p.m. At touchdown -- nominally about 2,500 ft. beyond the runway threshold -- the orbiter is traveling at a speed ranging from 213 to 226 mph. Discovery traveled 5,330,000 miles, landing on orbit 204. Mission elapsed time was 12 days, 20 hours, 44 minutes and 16 seconds. This is the 64th landing at KSC. Photo credit: NASA/Kim Shiflett
