STS-116 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Discovery. Discovery lifted off on 9 December 2006 at 20:47:35 EST. A previous launch attempt on 7 December 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.
Low Earth OrbitWildBlue-1 offers Ka-band Broadband Internet Access via satellite. Operates at 111.1 degrees West in a geostationary orbit. AMC-18 is an SES satellite that provides coverage to North America for many television networks. This satellite operates at 105 degrees West.
Geostationary Transfer OrbitThe GPS-IIR replenishment satellites are produced by General Electric Astrospace (later Martin Marietta and Lockheed Missiles & Space) under a contract issued in 1989, which included 21 satellites based on the commercial AS-4000 bus. These provided improved navigation accuracy and longer autonomous satellite operation than earlier model GPS satellites. The satellites were three-axis stabilized and operated at downlink frequencies of 1572.42 MHz and 1227.6 MHz (L-Band) and 2227.5 MHz (S-Band). Lockheed was responsible for launch and flight operations support of the GPS-IIR through 2006.
