Telstar 1 makes live trans-Atlantic TV broadcast, July 23, 1962 | EDN Telstar 1 makes live trans-Atlantic TV broadcast, July 23, 1962 PRINT PDF EMAIL The first live trans-Atlantic television satellite broadcast took place on July 23, 1962, and was made via AT&T’s Telstar 1 satellite. Telstar had been launched 13 days prior to the broadcast by Delta rocket from Cape Canaveral. It was the first privately sponsored space launch. 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. Limited by what the Delta rocket could carry, the satellite is roughly spherical (see photo), measures 34.5 inches in length, and weighs about 170 pounds. Telstar was spin-stabilized and its outer surface was covered with solar cells to generate power.

Telstar had one innovative transponder to relay data and 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 telecommands from a ground station. 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 transmission linked London and Paris to the US. The link is established at 10:58 BST . Telstar 1 also relayed the first telephone call to be transmitted through space later in the same day. Although no longer functional, Telstar remains in orbit as of this publishing.

This Satellite Earth Station was designed and built by the British Post Office Engineering Department. Known as 'Arthur' (of "Knights of the Round Table" fame), its open-dish design became a model for satellite television earth stations throughout the world. The plaque can be viewed at the Goonhilly Downs visitors centre in Cornwall, England. NOTE: As of 2015, the plaque has been taken down for protection, and is stored on site, but is not viewable by the public.

In April 1961 a multi-national agreements was signed between the American Telephone and Telegraph Company (AT&T), Bell Telephone Laboratories (Bell Labs) , NASA, the British Post Office, and the French National PPT (Post Office.) This agreement established a joint collaboration for the project development of two active, mobile telecommunications satellites, "TELSTAR" and "Relay." Goonhilly-Downs covers 140 acres and is located at the westernmost end of the Cornwall coast in England. It was selected because of the topography of the land. The first satellite dish to be built on the site, Goonhilly 1, also known as Arthur, was a parabolic design and weighs 1118 tons and was 28 meters in diameter. It set a world standard for the open parabolic design of the dish. The definition of a Parabolic Antenna is an antenna consisting of a parabolic reflector and a source at or near the focus. Microwave dish antenna is an example of a parabolic antenna.

Telstar Facts: The satellite was 90 centimeters in diameter It had 72 facets It weighed 77 kilograms The metal framework was made of magnesium, the shell of aluminum, coated with aluminum oxide sprayed on by a plasma jet process. Two antennas, transmitting and receiving, surrounded the satellite The satellite contained one electron tube, 2,528 semiconductor devices (1064 transistors and 1464 diodes.) The power was supplied by 19 rechargeable nickel-cadmium cells. They were charged by the 3600 solar cells on the exterior of the satellite. Telstar traveled at a rate of 8 kilometers per second It took Telstar 157.797 minutes to orbit the Earth. This is part of a triple dedication honoring TELSTAR. All ceremonies took place on 11 July 2002.

(Credit: Keystone/Getty Images) Share this: The Birth of Satellite TV, 50 Years Ago Author The Birth of Satellite TV, 50 Years Ago URL Google In television’s early years, North American and European viewers had to wait hours, if not days, for tapes to be shipped across the Atlantic in order to watch footage from the other side of the ocean. That all changed 50 years ago after the launch of the first telecommunications satellite: Telstar. On July 23, 1962, tens of millions of people watched a historic broadcast as Telstar beamed live transatlantic video into viewers’ living rooms for the first time. The age of satellite television had dawned. In homes across Rome, people barely touched their dinners. London’s pubs were packed, but bartenders served nary a drink. Throughout Europe, more than 100 million people huddled around television sets on the evening of July 23, 1962, to tune in to history. With Europeans watching eagerly, a black-and-white image of the Statue of Liberty flickered onto their screens. The picture itself was not particularly noteworthy except for one thing: it was live, via satellite.

The historic, live transatlantic broadcast was made possible by Telstar, a spherical satellite only the size of a large beach ball. Built by AT&T and dreamed up in Bell Labs, now the research arm of Alcatel-Lucent, Telstar received telephone calls, data, still pictures and fax images from ground stations in Andover, Maine, and France before amplifying them and relaying them across the Atlantic Ocean. A nickel cadmium battery and 3,600 solar cells protected by sapphire powered the 170-pound satellite, which roared into orbit from Cape Canaveral atop a NASA Thor-Delta rocket on July 10, 1962. Since AT&T paid NASA $3 million to launch the satellite, Telstar marked the first privately sponsored space initiative. After a successful initial test of the transatlantic television signal, the public rollout occurred during that special broadcast on July 23, 1962, which aired in Canada and 16 European countries and on all three major American networks.

Telstar could only broadcast signals when it was visible to ground stations on both sides of the Atlantic, meaning there was only a 20-minute transmission window during each two-and-a-half-hour orbit. The first 20-minute broadcast beamed by Telstar, referred to as a “television space extravaganza” by The Boston Globe, was slated to begin at 3 p.m. Eastern but started a couple minutes ahead of schedule as soon as Telstar came into range. As a monumental split screen—with the Statue of Liberty on the left side and the Eiffel Tower on the right—filled television screens in Europe and North America, legendary newsman Walter Cronkite intoned, “Good evening, Europe. This is the North American continent live via AT&T Telstar, July 23, 1962.” Viewers were then given a peek inside Chicago’s Wrigley Field at a baseball game between the Philadelphia Phillies and the Chicago Cubs. For many Europeans, it was the first time they had ever seen the sport. After Philadelphia’s Tony Taylor flied out and Johnny Callison followed with a hard-hit single to right field in the top of the third, the audience was switched to President John F.

Kennedy’s press conference in Washington, D.C. Unfortunately, viewers missed Kennedy’s opening remarks praising Telstar as “another indication of the extraordinary world in which we live” and instead listened to questions and answers on nuclear testing and the devaluation of the dollar. The program then bounced around with live scenes from the U.S.-Mexican border at Juarez, Niagara Falls, the World’s Fair in Seattle and the United Nations; a talk with astronauts at Cape Canaveral; and a look at actors at the Shakespeare Festival in Stratford, Ontario, rehearsing “Macbeth.” The finale featured close-ups of the stone faces of Mount Rushmore as the 312-member Mormon Tabernacle Choir sang “The Battle Hymn of the Republic.” Three hours later, on Telstar’s next orbit around the planet, it was Europe’s turn to broadcast live images to North American viewers for the first time. The European program opened with live pictures of London’s Big Ben and a welcome by the BBC’s Richard Dimbleby, hosting from Brussels. The broadcast was a televised Grand Tour of the continent’s great sites: the Sistine Chapel, the Champs-Élysées, the Louvre, the Colosseum and the Tower of London.

In one scene, viewers saw a Lapland girl in the Arctic Circle; in the next, Sicilian fishermen tending their nets. There were cultural morsels from paintings inside Yugoslavia’s national museum to horses performing to Chopin at Vienna’s famed Spanish Riding School to a performance of “La Tosca” amid ancient Roman ruins. After 19 minutes, the program abruptly ended as Telstar passed over the horizon, out of range of the ground station in Maine. While there were some minor flaws such as pictures that jumped or were out of focus, “the technical achievement was little short of awesome,” wrote New York Times television critic Jack Gould. Another newspaper account the next day said that Telstar had “shrunk the earth overnight.” In Europe, the baseball game proved to be the program’s most popular segment, certainly compared to the presidential press conference. As a Daily Mail television critic said, he “preferred to watch Americans play games than talk politics.” Telstar—with a moniker that still sounds cool and futuristic—instantly became geek chic. Within days of the television broadcast, Paris fashion designers rolled out Telstar ensembles.

Weeks later, the British band The Tornados hit number one on British and American charts with the futuristic instrumental song “Telstar.” Even in the 1970s and 1980s, Telstar lent its name to a Ford automobile, a primitive Coleco video game system and a black-and-white checkered soccer ball designed by Adidas that looked very similar to the satellite. Although a pop culture icon, Telstar 1 had a short life. Radiation from both American and Soviet high-altitude atomic tests bombarded the satellite and fried its transistors. Telstar went out of service in November 1962, came back online briefly but went quiet for good on February 21, 1963. Telstar 2 launched in May 1963, and other Telstar satellites followed it into orbit. While inoperable, Telstar 1 still circles the earth today, a monument to the birth of satellite communications.

Whalen In 500 years, when humankind looks back at the dawn of space travel, Apollo's landing on the Moon in 1969 may be the only event remembered. At the same time, however, Lyndon B. Johnson, himself an avid promoter of the space program, felt that reconnaissance satellites alone justified every penny spent on space. Weather forecasting has undergone a revolution because of the availability of pictures from geostationary meteorological satellites--pictures we see every day on television. All of these are important aspects of the space age, but satellite communications has probably had more effect than any of the rest on the average person. Satellite communications is also the only truly commercial space technology- -generating billions of dollars annually in sales of products and services. The Billion Dollar Technology In fall of 1945 an RAF electronics officer and member of the British Interplanetary Society, Arthur C. Clarke, wrote a short article in Wireless World that described the use of manned satellites in 24-hour orbits high above the world's land masses to distribute television programs. His article apparently had little lasting effect in spite of Clarke's repeating the story in his 1951/52 The Exploration of Space .

Perhaps the first person to carefully evaluate the various technical options in satellite communications and evaluate the financial prospects was John R. Pierce of AT&T's Bell Telephone Laboratories who, in a 1954 speech and 1955 article, elaborated the utility of a communications "mirror" in space, a medium-orbit "repeater" and a 24-hour-orbit "repeater." In comparing the communications capacity of a satellite, which he estimated at 1,000 simultaneous telephone calls, and the communications capacity of the first trans-atlantic telephone cable (TAT-1), which could carry 36 simultaneous telephone calls at a cost of 30-50 million dollars, Pierce wondered if a satellite would be worth a billion dollars. After the 1957 launch of Sputnik I, many considered the benefits, profits, and prestige associated with satellite communications. Because of Congressional fears of "duplication," NASA confined itself to experiments with "mirrors" or "passive" communications satellites (ECHO), while the Department of Defense was responsible for "repeater" or "active" satellites which amplify the received signal at the satellite--providing much higher quality communications.

In 1960 AT&T filed with the Federal Communications Commission (FCC) for permission to launch an experimental communications satellite with a view to rapidly implementing an operational system. The U.S. government reacted with surprise-- there was no policy in place to help execute the many decisions related to the AT&T proposal. By the middle of 1961, NASA had awarded a competitive contract to RCA to build a medium-orbit (4,000 miles high) active communication satellite (RELAY); AT&T was building its own medium-orbit satellite (TELSTAR) which NASA would launch on a cost-reimbursable basis; and NASA had awarded a sole- source contract to Hughes Aircraft Company to build a 24-hour (20,000 mile high) satellite (SYNCOM). The military program, ADVENT, was cancelled a year later due to complexity of the spacecraft, delay in launcher availability, and cost over-runs. By 1964, two TELSTARs, two RELAYs, and two SYNCOMs had operated successfully in space.

This timing was fortunate because the Communications Satellite Corporation (COMSAT), formed as a result of the Communications Satellite Act of 1962, was in the process of contracting for their first satellite. COMSAT's initial capitalization of 200 million dollars was considered sufficient to build a system of dozens of medium-orbit satellites. For a variety of reasons, including costs, COMSAT ultimately chose to reject the joint AT&T/RCA offer of a medium-orbit satellite incorporating the best of TELSTAR and RELAY. They chose the 24-hour-orbit (geosynchronous) satellite offered by Hughes Aircraft Company for their first two systems and a TRW geosynchronous satellite for their third system. On April 6, 1965 COMSAT's first satellite, EARLY BIRD, was launched from Cape Canaveral. Global satellite communications had begun. The Global Village: International Communications Some glimpses of the Global Village had already been provided during experiments with TELSTAR, RELAY, and SYNCOM. These had included televising parts of the 1964 Tokyo Olympics. Although COMSAT and the initial launch vehicles and satellites were American, other countries had been involved from the beginning.

AT&T had initially negotiated with its European telephone cable "partners" to build earth stations for TELSTAR experimentation. NASA had expanded these negotiations to include RELAY and SYNCOM experimentation. By the time EARLY BIRD was launched, communications earth stations already existed in the United Kingdom, France, Germany, Italy, Brazil, and Japan. Further negotiations in 1963 and 1964 resulted in a new international organization, which would ultimately assume ownership of the satellites and responsibility for management of the global system. On August 20, 1964, agreements were signed which created the International Telecommunications Satellite Organization (INTELSAT). By the end of 1965, EARLY BIRD had provided 150 telephone "half- circuits" and 80 hours of television service. The INTELSAT II series was a slightly more capable and longer-lived version of EARLY BIRD. Much of the early use of the COMSAT/INTELSAT system was to provide circuits for the NASA Communications Network (NASCOM). The INTELSAT III series was the first to provide Indian Ocean coverage to complete the global network.

This coverage was completed just days before one half billion people watched APOLLO 11 land on the moon on July 20, 1969. From a few hundred telephone circuits and a handful of members in 1965, INTELSAT has grown to a present-day system with more members than the United Nations and the capability of providing hudreds of thousands of telephone circuits. Cost to carriers per circuit has gone from almost $100,000 to a few thousand dollars. Cost to consumers has gone from over $10 per minute to less than $1 per minute. If the effects of inflation are included, this is a tremendous decrease! INTELSAT provides services to the entire globe, not just the industrialized nations. Hello Guam: Domestic Communications In 1965, ABC proposed a domestic satellite system to distribute television signals. The proposal sank into temporary oblivion, but in 1972 TELESAT CANADA launched the first domestic communications satellite, ANIK, to serve the vast Canadian continental area. RCA promptly leased circuits on the Canadian satellite until they could launch their own satellite. The first U.S.

domestic communications satellite was Western Union's WESTAR I, launched on April 13, 1974. In December of the following year RCA launched their RCA SATCOM F- 1. In early 1976 AT&T and COMSAT launched the first of the COMSTAR series. These satellites were used for voice and data, but very quickly television became a major user. By the end of 1976 there were 120 transponders available over the U.S., each capable of providing 1500 telephone channels or one TV channel. Very quickly the "movie channels" and "super stations" were available to most Americans. The dramatic growth in cable TV would not have been possible without an inexpensive method of distributing video. The ensuing two decades have seen some changes: Western Union is no more; Hughes is now a satellite operator as well as a manufacturer; AT&T is still a satellite operator, but no longer in partnership with COMSAT; GTE, originally teaming with Hughes in the early 1960s to build and operate a global system is now a major domestic satellite operator.

Television still dominates domestic satellite communications, but data has grown tremendously with the advent of very small aperture terminals (VSATs). Small antennas, whether TV-Receive Only (TVRO) or VSAT are a commonplace sight all over the country. New Technology The first major geosynchronous satellite project was the Defense Department's ADVENT communications satellite. It was three-axis stabilized rather than spinning. It had an antenna that directed its radio energy at the earth. It was rather sophisticated and heavy. At 500-1000 pounds it could only be launched by the ATLAS- CENTAUR launch vehicle. ADVENT never flew, primarily because the CENTAUR stage was not fully reliable until 1968, but also because of problems with the satellite. When the program was canceled in 1962 it was seen as the death knell for geosynchronous satellites, three-axis stabilization, the ATLAS-CENTAUR, and complex communications satellites generally. Geosynchronous satellites became a reality in 1963, and became the only choice in 1965. The other ADVENT characteristics also became commonplace in the years to follow.

In the early 1960s, converted intercontinental ballistic missiles (ICBMs) and intermediate range ballistic missiles (IRBMs) were used as launch vehicles. These all had a common problem: they were designed to deliver an object to the earth's surface, not to place an object in orbit. Upper stages had to be designed to provide a delta-Vee (velocity change) at apogee to circularize the orbit. The DELTA launch vehicles, which placed all of the early communications satellites in orbit, were THOR IRBMs that used the VANGUARD upper stage to provide this delta-Vee. It was recognized that the DELTA was relatively small and a project to develop CENTAUR, a high-energy upper stage for the ATLAS ICBM, was begun. ATLAS-CENTAUR became reliable in 1968 and the fourth generation of INTELSAT satellites used this launch vehicle. The fifth generation used ATLAS-CENTAUR and a new launch-vehicle, the European ARIANE. Since that time other entries, including the Russian PROTON launch vehicle and the Chinese LONG MARCH have entered the market. All are capable of launching satellites almost thirty times the weight of EARLY BIRD.

In the mid-1970s several satellites were built using three-axis stabilization. They were more complex than the spinners, but they provided more despun surface to mount antennas and they made it possible to deploy very large solar arrays. The greater the mass and power, the greater the advantage of three-axis stabilization appears to be. Perhaps the surest indication of the success of this form of stabilization was the switch of Hughes, closely identified with spinning satellites, to this form of stabilization in the early 1990s. The latest products from the manufacturers of SYNCOM look quite similar to the discredited ADVENT design of the late 1950s. Much of the technology for communications satellites existed in 1960, but would be improved with time. The basic communications component of the satellite was thr traveling-wave-tube (TWT). These had been invented in England by Rudoph Kompfner, but they had been perfected at Bell Labs by Kompfner and J. R. Pierce. All three early satellites used TWTs built by a Bell Labs alumnus. These early tubes had power outputs as low as 1 watt.

Higher- power (50-300 watts) TWTs are available today for standard satellite services and for direct-broadcast applications. An even more important improvement was the use of high-gain antennas. Focusing the energy from a 1-watt transmitter on the surface of the earth is equivalent to having a 100-watt transmitter radiating in all directions. Focusing this energy on the Eastern U.S. is like having a 1000-watt transmitter radiating in all directions. The principal effect of this increase in actual and effective power is that earth stations are no longer 100-foot dish reflectors with cryogenically-cooled maser amplifiers costing as much as $10 million (1960 dollars) to build. Antennas for normal satellite services are typically 15-foot dish reflectors costing $30,000 (1990 dollars). Direct-broadcast antennas will be only a foot in diameter and cost a few hundred dollars. Mobile Services In February of 1976 COMSAT launched a new kind of satellite, MARISAT, to provide mobile services to the United States Navy and other maritime customers.

In the early 1980s the Europeans launched the MARECS series to provide the same services. In 1979 the UN International Maritime Organization sponsored the establishment of the International Maritime Satellite Organization (INMARSAT) in a manner similar to INTELSAT. INMARSAT initially leased the MARISAT and MARECS satellite transponders, but in October of 1990 it launched the first of its own satellites, INMARSAT II F-1. The third generation, INMARSAT III, has already been launched. An aeronautical satellite was proposed in the mid-1970s. A contract was awarded to General Electric to build the satellite, but it was canceled--INMARSAT now provides this service. Although INMARSAT was initially conceived as a method of providing telephone service and traffic-monitoring services on ships at sea, it has provided much more. The journalist with a briefcase phone has been ubiquitous for some time, but the Gulf War brought this technology to the public eye. The United States and Canada discussed a North American Mobile Satellite for some time.

In the next year the first MSAT satellite, in which AMSC (U.S.) and TMI (Canada) cooperate, will be launched providing mobile telephone service via satellite to all of North America. Competition In 1965, when EARLY BIRD was launched, the satellite provided almost 10 times the capacity of the submarine telephone cables for almost 1/10th the price. This price-differential was maintained until the laying of TAT-8 in the late 1980s. TAT-8 was the first fiber-optic cable laid across the Atlantic. Satellites are still competitive with cable for point-to-point communications, but the future advantage may lie with fiber-optic cable. Satellites still maintain two advantages over cable: they are more reliable and they can be used point-to-multi-point (broadcasting). Cellular telphone systems have risen as challenges to all other types of telephony. It is possible to place a cellular system in a developing country at a very reasonable price. Long-distance calls require some other technology, but this can be either satellites or fiber-optic cable. The LEO Systems Cellular telephony has brought us a new technological "system"-- the personal communications system (PCS).

In the fully developed PCS, the individual would carry his telephone with him. This telephone could be used for voice or data and would be usable anywhere. Several companies have committed themselves to providing a version of this system using satellites in low earth orbits (LEO). These orbits are significantly lower than the TELSTAR/RELAY orbits of the early 1960s. The early "low-orbit" satellites were in elliptical orbits that took them through the lower van Allen radiation belt. The new systems will be in orbits at about 500 miles, below the belt. The most ambitious of these LEO systems is Iridium, sponsored by Motorola. Iridium plans to launch 66 satellite into polar orbit at altitudes of about 400 miles. Each of six orbital planes, separated by 30 degrees around the equator, will contain eleven satellites. Iridium originally planned to have 77 satellites-- hence its name. Element 66 has the less pleasant name Dysprosium. Iridium expects to be providing communications services to hand- held telephones in 1998. The total cost of the Iridium system is well in excess of three billion dollars.

In addition to the "Big LEOS" such as Iridium and Globalstar, there are several "little leos." These companies plan to offer more limited services, typically data and radiodetermination. Typical of these is ORBCOM which has already launched an experimental satellite and expects to offer limited service in the very near future. Prospect and Retrospect Arthur C. Clarke's 1945 vision was of a system of three "manned" satellites located over the major land masses of the earth and providing direct-broadcase television. The inherent "broadcast" nature of satellite communications has made direct-broadcast a recurrent theme--yet one never brought to fruition. The problems are not technical--they are political, social, and artistic. What will people be willing to pay for? This is the question-- especially with the availability of 120-channel cable systems. Hughes is apparently about to enter this field and may encourage others to do the same. Only then will Clarke's prophetic vision be fulfilled. There are currently six companies providing fixed satellite service to the U.S.: GE Americom, Alascom, AT&T, COMSAT, GTE, and Hughes Communications.

They operate 36 satellites with a net worth of over four billion dollars. The gound stations which communicate with these satellites are innumerable and may have a similar net worth. INTELSAT has had competition in the international market from Pan American Satellite since 1986. Orion Satellite is expected to begin international service in 1994. Since Canada began domestic satellite service in 1972, that country has been joined by the United States (1974), Indonesia (1976), Japan (1978), India (1982), Australia (1985), Brazil (1985), Mexico (1985), and many others. Each year from 10-20 communications satellites are launched valued at about $75 million each. The launch vehicles placing them in orbit have similar values. Both satellites and launch vehicles are multi-billion dollar businesses. The earth station business is equally large. Finally the communications services themselves are multi-billion dollar businesses. John R. Pierce was right--it would be worth a billion dollars.

1962: The Telstar 1 communications satellite relays the first trans-Atlantic television signal in history. Telstar was the product of an international collaboration to push the development of satellite communications. NASA, AT&T, Bell Labs and the French and British national post offices were all involved, with Bell Labs doing the actual construction. A spherical satellite festooned with solar panels and packed with transistors, Telstar used a helical antenna to receive microwave signals from the ground station, which were then amplified and rebroadcast to the main receiving station in southern England. This article has been reproduced in a new format and may be missing content or contain faulty links. Contact wiredlabs@wired.com to report an issue. The satellite was launched July 10 aboard a NASA Delta rocket and placed in an orbit that provided for a narrow, 20-minute transmission period per orbit. President Kennedy was supposed to launch this historic moment in communications with a trans-Atlantic press conference, but the transmission signal was acquired before JFK was ready, so Ernie Banks may have been the first human image relayed across the Atlantic.

Needing to kill a little time, the producers picked up a TV broadcast of a major league ballgame between the Philadelphia Phillies and Chicago Cubs from Wrigley Field. (Source: Wikipedia) July 10, 1962: Telstar 1 Transmits Firstr Intercontinental TV Broadcast - SpaceNews.com July 10, 1962: Telstar 1 Transmits Firstr Intercontinental TV Broadcast posted: 15 July 2008 08:43 am ET — AT&T’s Telstar 1 gained international fame its first day in orbit and opened the public’s eyes to the possibilities of satellite communications, though it would later become a dead end in the formation of what now is a multibillion-dollar industry. Telstar 1 launched from , , aboard a Thor-Delta rocket that placed it in a medium Earth orbit. It transmitted the first intercontinental TV broadcast and the first long distance call via satellite that same day. There were communications satellites before Telstar 1: NASA’s AT&T-built balloon-like Echo was launched in August 1960; and the U.S. Defense Department’s Courier 1B was launched in October 1960.

But Telstar 1 was the first active communications satellite, which amplified the signal it received and sent it back to Earth, according to the Loral Skynet Web site. Loral acquired the AT&T Telstar group, Skynet, in 1997, to form Loral Skynet. The Echo satellite passively bounced weakened intercontinental television and telephone signals back to Earth, and Courier 1B merely sent out a prerecorded message from then U.S. President Dwight D. Eisenhower.� �In its first broadcast, Telstar 1 televised a flag positioned above an AT&T Earth station in , , while playing “The Star-Spangled Banner,” and later that day transmitted a phone call between U.S. Vice President Lyndon Johnson in and AT&T Chairman Fred Kappel in . In the early 1960s U.S. President John F. Kennedy proposed establishing a worldwide communications satellite system, said Joseph Pelton, director of the space and advanced communications satellite organization at the Sen. Robert Kerr (R-Okla.) sponsored legislation that would have made the system a private initiative, while Sen.

Estes Kefauver (D-Tenn.) sponsored a separate bill for a public effort, Pelton said during a June 25 phone interview. The final legislation, which Kennedy helped push through, was a compromise, which established a commercial organization that included government appointees and was approved to handle international agreements with government oversight. Kennedy signed the Communications Satellite Act in August 1962.� Next, the decision on whether to use medium Earth or geosynchronous orbiting satellites to provide the global communications system had to be made. While reaching medium Earth orbit had become routine, it was extremely difficult to place a satellite into geosynchronous orbit at that time, Pelton said. AT&T proposed lofting 50 to 100 Telstar-type satellites to medium Earth orbit for worldwide coverage, and installing about 25 support stations on the ground, Pelton said. AT&T was not overly concerned about cost constraints and would have passed the high cost of its system on to its customers, Pelton said.

Built by AT&T’s Bell Laboratories under the leadership of John Pierce, who also led Echo’s development, Telstar 1 and Telstar 2, which launched May 7, 1963, tested out the proposed constellation concept, Pelton said. Telstar made a huge impact and “got a great deal of publicity,” Pelton said. A 1962 U.S. Information Agency poll showed that, in the United Kingdom was better known than Sputnik had been in 1957, according to the NASA History Web site. Despite its success, “[Telstar] was not a slam dunk, if you will, at this point in time,” Pelton said. While putting a satellite into geosynchronous orbit was much more difficult, a geosynchronous constellation would require only three satellites for global coverage at a much lower cost, Pelton said. Geosynchronous satellites also do not require as much ground support since they remain in a constant position in the sky and therefore do not need to be tracked by multiple ground stations. In addition to cost concerns, there was international pressure, especially from and , to adopt a geosynchronous system instead of a medium Earth orbiting constellation, Pelton said.

The international satellite organization, Intelsat, was established by negotiations between and European governments in 1964. It was created to establish and manage the global satellite communications system, and under its guidance communications satellite technology exploded. Syncom 3, the first successful geosynchronous communications satellite, was launched in August 1964, Pelton said. Ultimately, Intelsat eschewed AT&T’s Telstar system in favor of geosynchronous satellites. While it was in service Telstar 1 broadcast plays, music concerts, baseball games and news reports.�� search Telstar: Satellites Beamed First TV Signals Across the Ocean Start Over | More Quizzes Lucky first try Fortunately, unlike other satellites of the time, Telstar 1 launched on the first try. It soared into space on July 10, 1962, from its launch pad at Cape Canaveral in Florida.

The 34-inch (87 cm) spherical satellite, which weighed 171 pounds (77 kilograms), was inserted into an orbit of about 3,505 miles (5,640 kilometers) at its highest, and 903 miles (1,453 kilometers) at its lowest. This is quite different from the major communications satellites of today, which "hover" at one point above the surface in geosynchronous orbit , but bear in mind that this was a test. Telstar's first live television pictures in France — relayed only a few hours after launch, according to NASA — showed a U.S. flag outside of a receiving station in Maine. The satellite was also equipped to handle telephone calls and even picture faxes, and had an experiment that could examine the radiation in the Van Allen belts above Earth. "Telstar was a tremendous technical success, and the international reaction was spectacular," NASA later wrote in "Beyond the Ionosphere." "A U.S. Information Agency (USIA) poll showed that Telstar was better known in Great Britain than Sputnik had been in 1957.

Rather than launching a useless bauble, the Americans had put into orbit a satellite that promised to tie together the ears and eyes of the world." The satellite, in fact, was immortalized in a song in 1962. A British band called The Tornados created the song "Telstar," which hit No. 1 on the U.S. Billboard 100 at the height of its popularity. Many years later, Susanna Hoff, lead singer of the Bangles, wrote a 1991 song that mentioned the satellite; it was called "Wishing on Telstar." Monopoly concerns Telstar 1 started to have transmission difficulties in November 1962, and eventually saw its transmitter fail in February 1963. Telstar 2 launched on May 7, 1963. It was practically a twin of Telstar 1, but in this case, the satellite lasted until it was turned off in 1965 — longer than its predecessor. AT&T had clearly demonstrated acumen in how to build and use a satellite. They already had a monopoly in the telephone business, and according to NASA, there were those that feared that the monopoly could extend into space as well.

"AT&T's preeminent position as the largest U.S. common carrier and sole international telephone carrier, together with its willingness and ability to commit large sums of money to the development of communications satellites, convincingly suggested that commercial satellite utilization would very likely become AT&T utilization," NASA wrote. In August 1962, President John F. Kennedy approved the Communications Satellite Act . This act had been in the works for several years. The act placed U.S. satellite communications under a federally supervised company (with joint participation from several U.S. firms) called the Communications Satellite Corporation, or Comsat. While AT&T was a participant in Comsat, this ensured that the company could not have a space-faring monopoly. Comsat was later a founder of an entity called Intelsat that focused on international satellite coverage. In 1970, the Federal Communications Commission — under the Open Skies Policy — opened up domestic satellite communications launches to all firms that were capable of doing it. Comsat and Intelsat still exist today, but under very different structures. October 4, 2007 marks the 50th anniversary of the launch of the manmade satellite.

The Telstar satellites ushered in an era where satellites turned from experimental machines to sophisticated systems with great value to the companies producing them. A new wave of advanced geosynchronous spacecraft shares the Telstar name, but these commercial satellites are far more advanced than their predecessors. Telstar 301 launched in 1983, followed by Telstar 302 in 1984. Telstar 302, renamed Telstar 3C, was put into orbit by a Space shuttle Discovery crew. A dozen more satellites bearing the Telstar name have since been launched. Telstar 1 is still in orbit , as of February 2013, but it is no longer functional. — Elizabeth Howell, SPACE.com Contributor
