Artificial Satellites
Artificial Satellites are objects launched from earth to orbit earth or other planets. Satellites are used for communication, remote sensing, weather forecasting, and other purposes. This category is for questions about satellites in general or specific satellites.

What is needed to launch anything into space?
Energy enough to accelerate the object to an orbital velocity.
What orbits a planet and its not a moon?
An object which orbits a planet is generically called a satellite. The moon is a satellite, but so are artificial satellites, and occasionally asteroids and space junk.
Is there any other way to get Shedinja other than leaving a space in your party?
No, but it's not just leaving a space in your party,here, I'll explain it to you... You go to Rustboro City and go near the cave where you saved Peeko for the old man and catch a Nincada. You must have atleast 1 pokeball in your bag and have atleast 1 space left in your party. You train Nincada to level 20 and it will evolve into Ninjask. But, the Ninjask sheds its skin and become Shedinja. It goes in the empty pokeball in your bag and goes to the empty space in your party, and vuala, you have a Shedinja! Pretty simple, isn't it?=) Lata =~
Who invented the first satellite?
The first artificial satellite was made by the USSR. It was launched in 1957 and named Sputnik.
The Russians put the first satellite, Sputnik, into orbit. It was during the cold war, and it felt very odd knowing that 'something' made by Russia was floating around up there.
How many satellites are located around the Earth to help determine ones location?
There are exactly 24 operational GPS satellites around earth to determine one's location, but the Air Force usually tries to maintain 6 working but idle spares, for a total of 30 satellites.
Your receiver only needs signal from 4 to compute your location.
Russia has its own system (Glonass) and the EU maintains another. This probably gives a total of almost 100 satellites serving this purpose.
What was the first artificial satellite and who invented it?
The first artificial satellite was Sputnik 1. It was the size of a basketball and was made by the USSR (Union of Soviet Socialist Republics) or Russia. It was launched on October 4, 1957. The Soviets beat the first US satellite, Explorer 1, by four months. The main designers and developers of Sputnik 1 were M.S.Khomyakov, M.V.Krayushkin, S. Lidorenko and O. G. Ivanovsky.
Although workably invented by the Soviets, it is thought by some that the concept may have been postulated and triggered by a British science fiction writer named Arthur C. Clarke. In October 1945, Clarke published an essay in Wireless World (a British radio and electronics enthusiast magazine) titled "Extra-Terrestrial Relays - Can Rocket Stations Give Worldwide Radio Coverage?", in which he proposed geosynchronous communications satellites. This was twelve years before the USSR launched Sputnik.
The workability of artificial satellites was postulated by Robert A. Heinlein, an American science fiction writer, nearly a decade before Sputnik. Heinlein laid some scientific and engineering groundwork in his technical and creative involvement in the movie Destination Moon that was released in 1950.
What are the kinds of satellites?
There are two kinds of satellites: the artificial and natural satellite.
Do all satellites orbit the same direction?
No, all satellites do not orbit Earth at the same altitude. An good overview of this can be found on http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx. This overview reviews Low Earth Orbit, Medium Earth Orbit and Geostationary Orbits.
That would be "revolution", not "rotation". Let's assume you need a certain speed for a circular orbit. If the satellite (in this case) has a bit less speed, it will get closer and closer to the Earth, during half of its orbit. While doing this, its speed will increase; during the other half of its orbit, this speed will make it go away from the Earth again. The final result is that it moves around the Earth in an ellipse. This assumes, of course, that it doesn't approach the Earth too much. If it gets too close, it will be slowed down by the atmosphere, and eventually crash to Earth.
What do all those satellites do?
ok, you know if you are on a asocial networking site and chatting to get to the person's comp it goes up to the satelite and comes back down to their comp this also happens with t.v. ....
{| |- | Satellites are neither good nor bad. How they are used can be good or bad. While it is considered good to use their photographs to predict weather patterns, using them to spy on other countries is not considered good, though perhaps necessary. They are critical in today's world in providing communications services throughout the world. |}
What was the name of the first satellite launched by the russians and in what year was it launched?
The USSR launched Sputnik I, the first successful artificial satellite, on October 4, 1957.
What countries have launched satellites?
Over 60 countries have launched satellites. Of these, the three largest contributors to the number of satellites currently in orbit as of 2013 are Russia at 1457, the United States at 1110, and China at 140.
What was the first US satellite?
Explorer 1 was launched by the US on 31 January 1958, cylindrical in shape as opposed to the 'Sputnik' which had been round. It remained in orbit until March 1970. Its major achievement was the discovery of the Van Allen radiation belts around the Earth.
The first was Vangaurd.
The first successful U.S. satellite was Explorer I. It was launched into Earth orbit by the Army on January 31, 1958, at Cape Canaveral, Florida, four months after Russia orbited Sputnik. It weighed 18 pounds and had a cylindrical shape. It was 80 inches long and six inches in diameter.
What is needed to launch anything or anyone into orbit?
To date rockets are the only method that can be used to put something or someone into orbit.
How many watts does it take to get a signal to orbit?
At the company I work for, we send signals to orbit with 1 watt, but I'm sure it could be done with less. However, it depends on how fast a datarate you want, more power can generally get you a higher datarate.
