Soyuz TM-21 was the 21st mission and the 18th long-duration expedition to Mir space station. It was also a part of the US/Russian Shuttle-Mir Program. The mission began on March 14, 1995, 06:11:34 UTC, launching Commander Vladimir Dezhurov, Flight Engineer Gennady Strekalov and Research Cosmonaut Norman Thagard (who became the first American to ride the Soyuz) into orbit. They docked with Mir two days later. During their stay there, cosmonauts performed several EVAs to prepare for the docking of the new Spektr module. Station crew was visited by several Progress resupply spacecrafts, and welcomed aboard the STS-71 with the 19th expedition crew. Crews exchanged vehicles, and members of the 18th expedition returned aboard STS-71, landing safely back on Earth on 7 July 1995, 14:55:28 UTC. Soyuz TM-21 brought back the 19th expedition later on September 11, 1995, 06:52:40 UTC.
Low Earth OrbitSTS-63 was the first mission of the US/Russian Shuttle-Mir Program, which carried out the first rendezvous of the American Space Shuttle with Russia's space station Mir. Known as the 'Near-Mir' mission, the flight used Space Shuttle Discovery, which lifted off from launch pad 39B on 3 February 1995 from Kennedy Space Center, Florida.
Low Earth OrbitThe U.S. Navy began replacing and upgrading its ultra-high frequency (UHF) satellite communications network during the 1990s with a constellation of customized satellites built by Hughes Space and Communications Company. Known as the UFO (Ultra High Frequency Follow On) series, these HS-601 model satellites support the Navy's global communications network, serving ships at sea and a variety of other U.S. military fixed and mobile terminals.
Geostationary OrbitThe APStar 2 satellite was designed to serve two-thirds of the world's population - from China, Japan, and Vietnam on the east; to Russia, Eastern Europe, and India on the west; and to Australia on the south. APT Satellite Company, Ltd., of Hong Kong, ordered the high-power Hughes HS 601 spacecraft model in November 1993, as well as satellite control facility equipment and operator training.
