Intelsat
Intelsat S.A. (formerly Intel-Sat, Intelsat) is a Luxembourgish-American multinational satellite services provider with corporate headquarters in Luxembourg and administrative headquarters in Tysons, Virginia, United States. Originally formed as International Telecommunications Satellite Organization (''ITSO'', or Intelsat), from 1964 to 2001, it was an intergovernmental consortium owning and managing a constellation of communications satellites providing international telecommunications and broadcast services. In March 2023, rival satellite operator SES confirmed that it was in talks about a merger with Intelsat but in June 2023, it was announced that these discussions had ended. On 30 April 2024, SES announced that an agreement had been reached to acquire Intelsat for US$3.1 billion, with the transaction expected to close in the second half of 2025. As of June 2022, Intelsat operated a fleet of 52 communications satellites which was then one of the world's largest fleet ...

COMSAT
Communications Satellite Corporation (COMSAT) is a global telecommunications company based in the United States. By 2007, it had branches in Brazil, Argentina, Colombia, Mexico, Peru, Venezuela and several other countries in the Americas. Although it operated many kinds of data communication technologies, it is best known for its satellite communication services. History COMSAT Corporation was created by the Communications Satellite Act of 1962 and incorporated as a publicly traded company on February 1, 1963. The primary goal of COMSAT was to serve as a public, federally funded corporation intended to develop a commercial and international satellite communication system. Although the corporation was government regulated, it was equally owned by some major communications corporations and independent investors. COMSAT began operations with its headquarters in Washington, D.C., in 1962, with a six-person founding board of directors appointed by President John F. Kennedy, i ...

Intelsat I
Intelsat I (nicknamed Early Bird for the proverb "The early bird catches the worm") was the first commercial communications satellite to be placed in geosynchronous orbit, on April 6, 1965. It was built by the Space and Communications Group of Hughes Aircraft Company (later Hughes Space and Communications Company, and now Boeing Satellite Systems) for COMSAT, which activated it on June 28, 1965. It was based on the Syncom series of satellites that Hughes had previously built for NASA to demonstrate that communications via synchronous-orbit satellite were feasible. Its booster was a Thrust Augmented Delta (Delta D). After a series of maneuvers, it reached its geosynchronous orbital position over the Atlantic Ocean at 28° West longitude, where it was put into service. It helped provide the first live TV coverage of a spacecraft splashdown, that of Gemini 6 in December 1965. Originally slated to operate for 18 months, Early Bird was in active service for 4 years and 4 months ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PanAmSat
PanAmSat Corporation was a satellite service provider headquartered in Greenwich, Connecticut, United States. Founded in 1984 by Reynold "Rene" Anselmo, it operated a fleet of communications satellites used by the entertainment industry, news agencies, internet service providers, government agencies, and telecommunication companies. Anselmo got the idea for PanAmSat from Norm Leventhal, a communications lawyer in Washington, D.C., to whom he had turned to for advice regarding difficulties he was encountering in getting reasonably priced satellite transmission for his Spanish International Network (SIN), the current-day Univision. Anselmo financed the entire project himself and Leventhal's law firm, hiring Martin Rothblatt for special satellite technical advice, filed for approval from the Federal Communications Commission (FCC) and lining up an initial satellite from RCA Astro-Electronics and a heavily discounted launch from Arianespace. PanAmSat effectively broke the monop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Ocean
The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, with an area of about . It covers approximately 17% of Earth#Surface, Earth's surface and about 24% of its water surface area. During the Age of Discovery, it was known for separating the New World of the Americas (North America and South America) from the Old World of Afro-Eurasia (Africa, Asia, and Europe). Through its separation of Afro-Eurasia from the Americas, the Atlantic Ocean has played a central role in the development of human society, globalization, and the histories of many nations. While the Norse colonization of North America, Norse were the first known humans to cross the Atlantic, it was the expedition of Christopher Columbus in 1492 that proved to be the most consequential. Columbus's expedition ushered in an Age of Discovery, age of exploration and colonization of the Americas by European powers, most notably Portuguese Empire, Portugal, Spanish Empire, Sp ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Moon
The Moon is Earth's only natural satellite. It Orbit of the Moon, orbits around Earth at Lunar distance, an average distance of (; about 30 times Earth diameter, Earth's diameter). The Moon rotation, rotates, with a rotation period (lunar day) that is synchronized to its orbital period (Lunar month#Synodic month, lunar month) of 29.5 Earth days. This is the product of Earth's gravitation having tidal forces, tidally pulled on the Moon until one part of it stopped rotating away from the near side of the Moon, near side, making always the same lunar surface face Earth. Conversley, the gravitational pull of the Moon, on Earth, is the main driver of Earth's tides. In geophysical definition of planet, geophysical terms, the Moon is a planetary-mass object or satellite planet. Its mass is 1.2% that of the Earth, and its diameter is , roughly one-quarter of Earth's (about as wide as the contiguous United States). Within the Solar System, it is the List of Solar System objects by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extravehicular Activity
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable atmosphere of Earth, Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes spacewalks and Moon, lunar or planetary surface exploration (commonly known from 1969 to 1972 as moonwalks). In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVAs have been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became the first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. In 1984, Svetlana Savitskaya became the first woman to perform a spacewalk, conducting EVA outside the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
