X-ray telescopes are placed in orbit around the Earth to avoid absorption of X-rays by Earth's atmosphere. By being in space, these telescopes can capture high-energy X-ray emissions from celestial objects that do not reach the surface due to the atmosphere.
Mountaintops are ideal for near-infrared telescopes because the high altitude reduces atmospheric interference and light pollution. Ultraviolet telescopes are placed in Earth orbit to avoid absorption of ultraviolet light by Earth's atmosphere, which allows for clearer observations of objects emitting in the ultraviolet spectrum.
It was the first artificial (manmade) object to be placed in orbit around the earth. It started the space race between the USA and the USSR.
Earth's atmosphere does not limit a telescope's resolving power.
Telescopes are typically housed in observatories, which can be located in remote areas to minimize light pollution and atmospheric disturbances. They may also be found in research institutions, universities, and even some private homes. Many modern telescopes, especially space telescopes like the Hubble, are placed in orbit to avoid Earth's atmospheric interference. Additionally, some portable telescopes are kept by amateur astronomers for personal use.
The earth's atmosphere doesn't let these rays reach the ground, so the telescopes are placed in orbit where they can receive the rays.

There are several astronomical telescopes in orbit. The most famous is of course the Hubble, but COROT, MOST, and the Swift Gamma-Ray Burst Observer are all visible light telescopes in orbit around Earth, and there's another - Kepler - that doesn't orbit Earth, but does orbit the Sun. There are also a multitude of orbital telescopes that use segments of the electromagnetic spectrum other than visible. Spitzer, for example, uses infrared light (it's another solar orbiter).

An object is placed into orbit around the earth by acheiving a velocity of 7,814 meters per second for a low earth orbit. Converted, this equals 17479.42 miles per hour. In simpler terms, gravity.

You mean Earth observation satellites, and the answer is near-Polar low-Earth orbits. This means that as the satellite orbits from above one pole to the other, the Earth turns beneath it, and the satellite passes over the Equator, and every other point on its orbit, at a different place on each successive orbit. In this way, after enough orbits, it can view the whole Earth. Earth observation satellites are placed in low-Earth orbit because (a) they travel faster over the ground at lower altitude and (b) being closer to the ground, their telescopes do not need to be so powerful to achieve a given spatial resolution. Military observation, or spy, satellites, are often placed in a high parking orbit until they are needed, whereupon they are placed into a highly elliptical orbit to allow them to come very close to Earth (and hence see it with great detail) over the region of interest.
