Telstar 1 is a defunct communications satellite launched by NASA on July 10, 1962. It was the satellite that allowed the first live broadcast of television images between the United States and Europe. Telstar 1 remained active for only 7 months before it prematurely failed due to Starfish Prime, a high-altitude nuclear test conducted by the United States. Although the satellite is no longer operational, it remains in Earth orbit.
STS-41-D was the 12th flight of NASA's Space Shuttle program, and the first mission of Space Shuttle Discovery. It was launched from Kennedy Space Center, Florida, on August 30, 1984, and landed at Edwards Air Force Base, California, on September 5, 1984. Three commercial communications satellites were deployed into orbit during the six-day mission, and a number of scientific experiments were conducted, including a prototype extendable solar array that would eventually form the basis of the main solar arrays on the International Space Station (ISS).
H-IIA (H-2A) is an active expendable launch system operated by Mitsubishi Heavy Industries (MHI) for the Japan Aerospace Exploration Agency. These liquid fuel rockets have been used to launch satellites into geostationary orbit; lunar orbiting spacecraft; Akatsuki, which studied the planet Venus; and the Emirates Mars Mission, which was launched to Mars in July 2020. Launches occur at the Tanegashima Space Center. The H-IIA first flew in 2001. As of December 2021, H-IIA rockets were launched 45 times, including 39 consecutive missions without a failure, dating back to 29 November 2003.
Telesat, formerly Telesat Canada, is a Canadian satellite communications company founded on May 2, 1969. The company is headquartered in Ottawa.
Telstar 301 is an American communications satellite launched in July 1983 and operated by AT&T. It was one of three Telstar 3 satellites, followed by Telstar 302 in 1984 and Telstar 303 in 1985.
SBS 4 was a geostationary communications satellite designed and manufactured by Hughes on the HS-376 platform. It was ordered by Satellite Business Systems, which later sold it to Hughes Communications. It had a Ku band payload and operated at 94°W longitude.
Intelsat Americas, was the re-designation given to the several Telstar satellites serving North America following their sale to Intelsat by Loral Space & Communications in 2003. On February 1, 2007, they were renamed under the "Galaxy" brand. The Telstar satellites that do not directly serve the United States retained their original Telstar designation.
Commercial use of space is the provision of goods or services of commercial value by using equipment sent into Earth orbit or outer space.
Telespazio Spa is a European spaceflight services company founded in 1961. It is a joint venture owned by Leonardo (67%) and Thales Group (33%) headquartered in Rome.
AlphaStar Digital Television was a direct-to-home satellite broadcasting service for the United States market developed by Canadian firm Tee-Comm Electronics. It was the first direct-to-home satellite broadcasting service in the United States to use the internationally accepted DVB-S broadcasting standard and used 39" satellite dish receivers. Its service launched in July 1996, but was discontinued completely by September 1997 with 40,000 subscribers as the company went through bankruptcy proceedings. The American assets of AlphaStar was used under the auspices of the Champion Telecom Platform which used to own the AlphaStar brand. AlphaStar would also have alleviated a shortage of Canadian satellite capacity by using foreign (US) satellite capacity to fill Canadian needs—indeed this was a requirement for the Canadian company to obtain its license from Canada to commence broadcasting. Tee-Comm, the parent company of AlphaStar had originally co-founded the partnership that created ExpressVu as technology supplier but later divested all interest in ExpressVu.
Galaxy 28 is a communications satellite owned by Intelsat located at 89° West longitude, serving the North America and South America market.
It was built by Space Systems/Loral, as part of its SSL 1300 line = . aka Galaxy 28 was formerly known as Telstar 8 and Intelsat Americas 8. This satellite provides services in the C-band, Ku-band, and Ka-band.
DDISHTV is a Mongolian Direct-to-home television service provider company led by Bars Ganbold (CEO).
Telstar is the name of various communications satellites. The first two Telstar satellites were experimental and nearly identical. Telstar 1 launched on top of a Thor-Delta rocket on July 10, 1962. It successfully relayed through space the first television pictures, telephone calls, and telegraph images, and provided the first live transatlantic television feed. Telstar 2 was launched May 7, 1963. Telstar 1 and 2—though no longer functional—still orbit the Earth.
Telstar 14R, also known as Estrela do Sul 2 is a commercial communications satellite in the Telstar series built by Space Systems/Loral for Telesat to provide Ku-band communications to South America and the Southern United States. It is a replacement for Telstar 14, whose north solar array failed to open after launch, limiting its mission effectiveness. Telstar 14R experienced the same problem, with its north solar array failing to open too, but is now in service despite that failure.
Telstar 14 or Estrela do Sul 1 is a commercial communications satellite in the Telstar series built by Space Systems/Loral (SS/L) for Telesat to provide Ku-band communications to South America and the Southern United States. Estrela do Sul 1 was launched by Sea Launch using a Zenit-3SL carrier rocket on 11 Jan 2004 for geosynchronous orbit at 63 degrees west.
Telstar 303 is a U.S. communications satellite launched from Space ShuttleDiscovery during STS-51-G on 17 June 1985. Owned by AT&T and operated by Loral Skynet Hughes Communications, it was one of three Telstar 3 satellites, preceded by Telstar 301 in 1983 and Telstar 302 in 1984.
Telstar 19V(Telstar 19 Vantage) is a communication satellite in the Telstar series of the Canadian satellite communications company Telesat. It was built by Space Systems Loral (MAXAR) and is based on the SSL-1300 bus. The satellite was designed to provide additional capacity over the North Atlantic region. As of 26 July 2018, Telstar 19V is the heaviest commercial communications satellite ever launched, weighing at 7,076 kg (15,600 lbs) and surpassing the previous record, set by TerreStar-1 (6,910 kg/15230lbs), launched by Ariane 5ECA on 1 July 2009.
Telstar 18 is a Russian communications satellite that was launched by a Zenit-3SL rocket from the Ocean Odyssey platform floating on the equatorial Pacific Ocean at 04:00 UT on 29 June 2004. It was intended to be a geostationary satellite, but due to the premature stoppage of the boost from the final DM-SL stage, it ended at 21000 km, far below the geostationary orbit. Trim-maneuver thrusters attached to the satellite were used to slowly raise to geostationary orbit to an approximately geostationary status at 36000 km.
Telstar 18V(Telstar 18 Vantage / APStar 5C) is a communication satellite in the Telstar series of the Canadian satellite communications company Telesat. T18V will be equipped with C and Ku-band transponders and operate from 138° East. At 7,060 kilograms (15,560 lb), it is the second-heaviest communication satellite ever launched, weighing slightly less than its sibling Telstar 19V.
Telstar 402 was a communications satellite owned by AT&T Corporation.
