The astronauts of NASA's STS-116 space shuttle mission visited NASA Stennis Space Center in south Mississippi to share highlights of their 13-day mission and to thank SSC employees for the reliability of the space shuttle's main engines, which helped propel Space Shuttle Discovery into orbit during its Dec. 9, 2006, launch. Pictured (from left) are STS-116 crewmembers Commander Mark Polansky, Pilot Bill Oefelein, Mission Specialist Robert Curbeam, SSC Center Director, Richard Gilbrech, Mission Specialists Joan Higginbotham, Nicholas Patrick and Christer Fuglesang. During the mission, which began with the first evening launch since 2002, the astronauts installed the P5 spacer truss segment and rewired the International Space Station's power system.
