What is a Satellite?

A synonym for disposal orbit. Many do jobs that call for high orbital inclination they swing write about artificial satellites orbiting and below the equatorso they can communicate, or look at other areas.

Some suggest bringing down dead satellites in some wayperhaps using a net or air bursts to disturb the debris from its orbit and bring it closer to Earth. A geosynchronous orbit with an inclination of zero.

Artificial Satellites

Geocentric orbits may be further classified by their altitude, inclination and eccentricity. End of life[ edit ] When satellites reach the end of their mission this normally occurs within 3 or 4 years after launchsatellite operators have the option of de-orbiting the satellite, leaving the satellite in its current orbit or moving the satellite to a graveyard orbit.

I have just finished my report on artificial satellites. More than 50 countries own a satellite or a significant share in one, according to the Union of Concerned Scientists. Communication payload[ edit ] The second major module is the communication payload, which is made up of transponders.

See asteroids Cruithne and AA Mercury and Venus each have no moons. The Race to Space ; M. The focus on satellites as political tools began to give way to people as both countries sent humans into space in One is called low-Earth-orbitwhich extends from about to 2, km about to 1, miles.

Current weather satellites can transmit visible or infrared photos, focus on a narrow or wide area, and maneuver in space to obtain maximum coverage. Artificial satellites, however, did not become a reality until the midth century.

At the moment, there are hundreds of active artificial satellites orbiting the Earth. Weather satellites improved forecasts, even for remote areas. Geostationary or geosynchronous orbit is the best spot for communications satellites to use, however.

This is different from the natural satellites, or moons, that orbit planets, dwarf planets and even asteroids. That means that the satellite always stays over one spot on Earth. However, a satellite needs to be going fast — at least 8 km 5 miles a second — to stop from falling back down to Earth immediately.

We all know that the Earth is round. Most satellites also work in this zone. Currently there are approximately 1, [20] artificial satellites orbiting the Earth. Patients in isolated areas can access medical experts through video, telephone, and data links. Kallen, The Giant Leaps: The surprisingly simple answer to this question lies in the shape of the Earth.

What keeps a satellite from falling to Earth? As will be seen below, however, not all artificial satellites are necessarily workable ones. The list includes the European Space Agencya multi-national state organization, but does not include private consortiums.

It is vital for an individual and the society as a whole to survive.Though Artificial Satellites have mostly orbited Earth, some have orbited the moon, the sun, asteroids, Venus, Mars and Jupiter; these satellites mostly study the body around which they're orbiting.

Satellite (artificial)

As a satellite is any object that orbits another, Artificial Satellites are people-made. An artificial satellite is an object that people have made and launched into orbit using rockets.

There are currently over a thousand active satellites orbiting the Earth. The size, altitude and design of a satellite depend on its purpose. About 1, active satellites, both government and private. Plus there are about 2, ones that no longer work. Russia launched the first satellite, Sputnik 1, in A satellite is an object in space that orbits or circles around a bigger object.

There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial. Artificial satellites are used for many purposes, including communications, navigation, gathering weather information, creating maps and even spying.

Artificial satellites come in several forms, including telescopes and probes. satellite, artificial Artificial object placed in orbit around the Earth or other celestial body. Satellites can perform many tasks, including sending back data or pictures to the Earth.
