A satellite is an object that is in orbit around an object in space of a larger size. Things such as the Earth's Moon or Pluto's Charon are natural satellites. Humans have also created artificial satellites—human-made machines and spacecraft in orbit around our Earth or other objects in our galaxy. These types of satellites have fundamentally changed humanity—such as connecting us with ...
Communications satellites are one such technology, and they play a major role in our daily lives. Prior to the 1960s, long-distance communication via radio, telephone, and television networks was a challenge. Local areas often had very good coverage, and broad networks might blanket a nation, but the whole world wasn't yet covered.
Today, hundreds of civilian and military applications satellites ring the Earth, often operating side-by-side in orbit. They provide similar services—communications, photography, remote sensing, weather analysis, and navigation—reaching different but occasionally overlapping communities of users. These satellites have become an integral part of contemporary life. We take for granted daily ...
Most communications satellites have the same basic components, pointed out in this diagram: Solar cells and batteries to power the satellite systems Antennas to receive and transmit signals Transponder to alter the frequency of incoming signals (avoiding interference with outgoing signals) and to amplify signals before transmitting them back to Earth Orientation and propulsion systems to keep ...
Telstar was one of the most significant communications satellites of the early space age. It raised an important policy question: Should communications satellites be operated and controlled by private corporations or under government auspices? The United States chose government direction and created two new institutions, COMSAT and INTELSAT, to develop satellite communcations, an arrangement ...
And Russia and China, over the objections of the rest of the world, continue to experiment and test space-based weapons that can physically attack another nation’s orbiting satellites.
TIROS I, and a series of successor test satellites, provided the technical experience to start separate civilian and military space-based weather observation programs. By the mid 1960s, the civilian TIROS program launched a series of satellites to provide routine, daily weather observations. The program is still in operation today and, in conjunction with other weather satellites, has made ...
Echo satellites, manufactured by the G.T. Schjeldahl Co., posed a unique technical challenge. They were sent into orbit folded flat and then inflated in space. Inflation had to proceed carefully to ensure the integrity of the satellite's "balloon" surface. This one is a flight spare folded in its launch canister.
A natural satellite is a naturally occurring object that is in orbit around an object in space of a larger size. Earth's natural satellite is the Moon, but many objects in our Solar System have multiple natural satellites. Humans have also created artificial satellites—human-made machines and spacecraft in orbit around our Earth or other objects in our galaxy.
