Telstar
Encyclopedia
Telstar is the name of various communications satellite
s, including the first such satellite to relay television signals.
The first two Telstar satellites were experimental and nearly identical. Telstar 1 was launched on top of a Thor-Delta
rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, fax
images and provided the first live transatlantic television feed. Telstar 2 was launched May 7, 1963.
, the original Telstar was part of a multi-national agreement between AT&T, Bell Telephone Laboratories
, NASA
, the British General Post Office, and the French National PTT (Post, Telegraph & Telecom Office)
to develop experimental satellite communications over the Atlantic Ocean
. Bell Labs held a contract with NASA, reimbursing the agency three million pounds for each launch, independent of success. The US ground station was Andover Earth Station
in Andover, Maine
, built by Bell Labs.
The main British ground station was at Goonhilly Downs
in southwestern England, and it was used by the BBC
. It was the international coordinator and the standards 525/405 conversion equipment (filling a large room) was researched and developed by the BBC and located in the BBC Television Centre
, London. The French ground station was at Pleumeur-Bodou (48°47′10"N 3°31′26"W) in north-western France
.
The satellite was built by a team at Bell Telephone Laboratories, including John Robinson Pierce
, who created the project; Rudy Kompfner, who invented the traveling wave tube
transponder used in the satellite; and James M. Early
, who designed its transistors and solar panels. The satellite is roughly spherical, measures 34.5 inches (876.3 mm) in length, and weighs about 170 pounds (77.1 kg). Its dimensions were limited by what would fit on one of NASA's Delta rocket
s. Telstar was spin-stabilized, and its outer surface was covered with solar cell
s to generate electrical power. The power produced was a tiny 14 watts.
The original Telstar had one innovative transponder
to relay data, which was a television channel or multiplexed
telephone circuits. An omnidirectional
array of small antenna elements around the satellite's "equator" received 6 GHz microwave
signals to be relayed. The transponder converted the frequency
to 4 GHz, amplified the signals in a traveling-wave tube, and retransmitted them omnidirectionally via the adjacent array of larger box-shaped cavities. The prominent helical antenna
was for telecommand
s from a ground station.
Launched by NASA
aboard a Delta rocket
from Cape Canaveral
on July 10, 1962, Telstar 1 was the first privately-sponsored space launch. A medium-altitude satellite, Telstar was placed in an elliptical orbit
completed once every 2 hours and 37 minutes, inclined at an angle of approximately 45 degrees to the equator, with perigee
about 1000 km from Earth and apogee about 6000 km from Earth This is in contrast to most of today's communications satellites, which are placed in circular geostationary orbit
s.
Due to its non-geosynchronous orbit
, Telstar's availability for transatlantic signals was limited to the 20 minutes in each 2.5 hour orbit when the satellite passed over the Atlantic Ocean
. Ground antennas had to track the satellite with a pointing error of less than 0.06 degrees as it moved across the sky at up to 1.5 degrees per second.
Since the transmitting and receiving radio systems on board Telstar were not nearly as powerful or capable as those of today's satellites, the ground antennas had to be huge. Morimi Iwama and Jan Norton of Bell Laboratories were in charge of designing and building the electrical portions of the system that steered the antennas. The aperture of the antennas was 3600 square feet (334.5 m²). The antennas were 177 feet (53.9 m) long and weighed 380 tons. The antennas were housed in radome
s the size of a 14-story office building.
and in North America by NBC, CBS, ABC, and the CBC
. The first public broadcast featured CBS's Walter Cronkite
and NBC's Chet Huntley
in New York, and the BBC's Richard Dimbleby
in Brussels. The first pictures were the Statue of Liberty in New York and the Eiffel Tower in Paris. The first broadcast was to have been remarks by President
John F. Kennedy
, but the signal was acquired before the president was ready, so the lead-in time was filled with a short segment of a televised major league baseball
game between the Philadelphia Phillies
and the Chicago Cubs
at Wrigley Field
. The batter, Tony Taylor
, was seen hitting a ball pitched by Cal Koonce to the right fielder George Altman
. From there, the video switched first to Washington, DC; then to Cape Canaveral, Florida; then to Quebec
, Canada and finally to Stratford, Ontario
. The Washington segment included a press conference with President Kennedy, talking about the price of the American dollar, which was causing concern in Europe.
During that evening, Telstar 1 also relayed the first telephone
call to be transmitted through space, and it successfully transmitted faxes, data, and both live and taped television, including the first live transmission of television across an ocean from Andover, Maine to Goonhilly Downs, England and Pleumeur-Bodou, France. (An experimental passive satellite, Echo 1
, had been used to reflect and redirect communications signals two years earlier, in 1960.) In August 1962, Telstar 1 became the first satellite used to synchronize time between two continents, bringing the United Kingdom and the United States to within 1 microsecond of each other (previous efforts were only accurate to 2000 microseconds).
Telstar 1, which had ushered in a new age of the benevolent use of technology, became a victim of technology during the Cold War
. The day before Telstar 1 was launched, the United States had tested a high-altitude nuclear bomb (called Starfish Prime
) which energized the Earth's Van Allen Belt where Telstar 1 went into orbit. This vast increase in radiation, combined with subsequent high-altitude blasts, including a Soviet test in October, overwhelmed Telstar's fragile transistors; it went out of service in early December 1962, but was restarted by a workaround in early January 1963. The additional radiation associated with its return to full sunlight once again caused a transistor failure, this time irreparably, and Telstar 1 went out of service on February 21, 1963.
According to the US Space Objects Registry, Telstar 1 and 2 were still in orbit as of May 2010.
Experiments continued, and by 1964, two Telstars, two Relay
units (from RCA
), and two Syncom
units (from the Hughes Aircraft Company) had operated successfully in space. Syncom 2 was the first geosynchronous satellite
and its successor, Syncom 3, broadcast pictures from the 1964 Summer Olympics
. The first commercial geosynchronous satellite
was Intelsat I
("Early Bird") launched in 1965.
The second wave of Telstar satellites launched with Telstar 301
in 1983, followed by Telstar 302 in 1984 (which was renamed Telstar 3-D after carried into space by Shuttle mission STS-41-D
), and by Telstar 303 in 1985.
The next wave, starting with Telstar 401
, came in 1993; which was lost in 1997 due to a magnetic storm, and then Telstar 402 was launched but destroyed shortly after in 1994. It was replaced in 1995 by Telstar 402R, eventually renamed Telstar 4.
Telstar 10
was launched in China in 1997 by APT Satellite Company, Ltd.
In 2003, Telstars 4–8 and 13 — Loral Skynet's North American fleet — were sold to Intelsat
. Telstar 4 suffered complete failure prior to the handover. The others were renamed the Intelsat Americas
5, 6, etc. At the time of the sale, Telstar 8 was still under construction by Space Systems/Loral
, and it was finally launched on June 23, 2005 by Sea Launch
.
Telstar 18 was launched in June 2004 by Sea Launch
. The upper stage of the rocket underperformed, but the satellite used its significant stationkeeping fuel margin to achieve its operational geostationary orbit
. It has enough on-board fuel remaining to allow it to exceed its specified 13-year design life.
composed a popular instrumental recording in 1962, named "Telstar
" after the satellite; it was originally performed by The Tornados
and covered by The Ventures
and Bobby Rydell
among many others. Sound effects on the record, intended to symbolize radio signals, were produced by Meek running a pen around the rim of an ashtray, and then playing the tape of it in reverse.
Dutch singer, composer and record producer Johnny Hoes founded his own record label in the early 1960s, which he named Telstar. It soon became one of the Netherlands' most successful independent record companies.
Robert Calvert
wrote lyrics which he performed in the early 1980s to the tune of the Joe Meek
