The History of Satellite Communications
| Oct. 4, 1957 -- The world changed forever when the Soviet Union launched into orbit a basketball-sized satellite named Sputnik. Circling the Earth at 18,000 mph, Sputnik (Russian for "fellow traveler"), became history's first man-made satellite. Its launch stunned the world and began the Space Age. |

31, 1958 -- Embarrassed by the Soviet victory, the U.S. quickly
refits a missile rocket
and launches Explorer I, a 30-pound, 80-inch satellite into orbit.
June 1960 -- The first Echo satellite, a 135-foot diameter Mylar-coated balloon is sent into orbit and radio waves are bounced off of its mirror-like surface. 1961 -- RCA Corp. launches Relay I, one of the first satellites with a repeater device which captures radio waves and amplifies them before sending them back.

| 1962 -- the telecommunications age begins with the launch of TELSTAR I, a low-orbit satellite that beams the first live television broadcasts between Europe and the United States. With TELSTAR's success, a global satellite technology consortium called INTELSAT is created. |

| July 26, 1963 -- INTELSAT launches Syncom II, the first fully operational gyosynchronous satellite, providing the first uninterrupted satellite transmissions. |

| 1960 -- Tiros I, the world first Orbiting Observation satellite is launched. Soon, satellites are mapping cloud cover, weather patterns and global climate change. |

| 1965 -- The Soviet Union, Indonesia, Japan and Canada launch satellite systems to provide telephone and television service to their most-remote citizens. |

| 1977-'79 -- AT&T, RCA and Western Union launch communications satellites with government assistance. In 1979, the satellite industry is deregulated, allowing commercial rocket companies to compete for launches. In 1978, PBS Broadcasting becomes the first TV network to transmit programs to its affiliates via satellite. In 1981, the U.S. Space Shuttle program begins, offering an inexpensive way to launch satellites. |

| 1980 -- Home satellite TV begins with the first sales of backyard dishes. In 1988, the Federal Communications Commission allows satellite broadcasters to "scramble" signals so dish-owners can't steal signals. By 1996, there are 6 million U.S. homes with satellite TV dishes. |

| April 4, 1990
-- The Hubble telescope satellite is launched, providing deep space
pictures that prove the existence of black holes, photograph distant
galaxies and discover the size and age of the Universe.

1994 - The first Global Position Satellite constellation (a network of 24 geosynchronous satellites) begins operation, allowing pilots, boaters and motorists to instantly locate their exact position. | |
| 1995-1997
-- Companies worldwide launch satellite constellations
providing global coverage for their customers. From 1995 to 1997, $100
million a month is spent on communications satellite programs
worldwide. 1998 to 2003 -- The satellite industry goes into decline. First, the spread of fiber optic technology (which offers better video quality, higher data transfer and no time delay) is more appealing to consumers for phone, video and Internet service. Second, the grounding of the Space Shuttle program makes launches by rockets more expensive. And third, a global economic crisis slows down new satellite projects.

| 2004 and beyond -- New
technology developed by Hughes Network Systems could solve the
time-delay problem that has made satellites unpopular for Internet
users. The Spaceway constellation, which will launch in 2005, will handle more capacity at greater speed than any satellites in
existence.
