Space Shuttle Discovery approaches an illuminated Runway 15 at NASA Kennedy Space Center's Shuttle Landing Facility on the shortest day of the year.

Near sunset, Space Shuttle Discovery approaches an illuminated Runway 15 at NASA Kennedy Space Center's Shuttle Landing Facility on the shortest day of the year, concluding mission STS-116. 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. Aboard Discovery are Commander Mark Polansky, Pilot William Oefelein, and Mission Specialists Robert Curbeam, Joan Higginbotham, Nicholas Patrick and Christer Fuglesang, who represents the European Space Agency, as well as Thomas Reiter, who is returning from a 6-month stay on the International Space Station. During the 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.
