STS-116 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Discovery. Discovery lifted off on December 9, 2006, at 20:47:35 EST. A previous launch attempt on December 7 had been canceled due to cloud cover. It was the first night launch of a Space Shuttle since STS-113 in November 2002. The mission is also referred to as ISS-12A.1 by the ISS program. The main goals of the mission were delivery and attachment of the International Space Station's P5 truss segment, a major rewiring of the station's power system, and exchange of ISS Expedition 14 personnel. The shuttle landed at 17:32 EST on December 22, 2006, at Kennedy Space Center 98 minutes off schedule due to unfavorable weather conditions. This mission was particularly notable to Sweden, being the first spaceflight of a Scandinavian astronaut (Christer Fuglesang). STS-116 was the final scheduled Space Shuttle launch from Pad 39B as NASA reconfigured it for Ares I launches. The only remaining use of Pad 39B by the shuttle was as a reserve for the STS-400 Launch on Need mission to rescue the crew of STS-125, the final Hubble Space Telescope servicing mission, if their shuttle became damaged. After STS-116, Discovery entered a period of maintenance. Its next mission would be STS-120 starting on October 23, 2007. Crew Crew notes Originally this mission was to carry the Expedition 8 crew to the ISS. The original crew was to be: Mission highlights The STS-116 mission delivered and attached the International Space Station's third port steel truss segment, the P5 truss. The STS-116 mission brought to the Station Expedition 14 crew member Sunita Williams (who subsequently established a record for most time in space for a female astronaut) and brought home Expedition 14 crew member Thomas Reiter from European Space Agency (launched by STS-121). Christer Fuglesang became Sweden's first astronaut. His flight was a rare occurrence of two ESA astronauts flying in space together. The third of three SPHERES testbeds launched to the ISS. Astronauts completed major rewiring of the electrical system of the International Space Station in order to bring online the P3/P4 solar array installed by STS-115 in September 2006. Additional rewiring was done to ISS Pressurized Mating Adapter 2 (PMA2) to enable Station-Shuttle Power Transfer System (SSPTS) commencing with STS-118. One half of the original P6 solar array installed by STS-97 was folded to make room for the
