Because that's how physics works.
Satellites are "pulled" towards the Earth (or towards whatever they're satellites of) by gravity. However, they're also moving "sideways" at the same time.
You can think of a satellite as constantly falling, but also moving sideways fast enough that by the time they've fallen far enough to impact the surface, they've moved to the side enough to miss the primary completely.
The actual situation is a little more complicated than that (among other things, the directions of "down" and "sideways" keep changing), but that should be close enough to help convince you that satellites don't need anything except speed (their orbital velocity) to make them "stay up".
Actually, maybe I can do even better. If you do a coordinate transformation into a rotating frame in which the directions of "down" and "sideways" become constant, a new force will appear in the equations, which is diametrically opposed to ... and exactly enough to ... balance the pull of gravity.
because the satellite is controlled by scientists
For a satellite to stay in one place over the earth, the satellite must be going in orbit in the same direction that the earth spins. The satellite must also travel at the same pace/speed as the earth spins to give us the 24-hour day that we as people witness. To apparently stay in one place it must be in a synchronous orbit. For the earth this is about 24,000 miles altitude. It must also be an equatorial satellite.
A Geostationary orbit - it means that the satellite will always stay above the same point on Earth. Hope that helps
They go around and around. More artificial satellites proceed from west to east, because it takes less energy (fuel) to launch a satellite into that kind of orbit. But there's no fundamental reason why a satellite can't go in any direction you want. The only requirements are . . . -- The center of the Earth has to be in the plane of the orbit. -- If you expect it to stay up there for a while, then the satellite has to stay outside most of the Earth's atmosphere.

The satellite from Stay Tune usually creates an astral plane.
No, the cable will not work when the satellite is out. The satellite is what brings you the picture. If you are concerned about the satellite, I would stay with cable.
yes
It will stay with the satellite for a while, in a similar orbit. If the satellite is in low orbit, gradually the object will get away from the satellite, due to "tidal forces" from Earth.
which satellite........

In satellite communication, up link refers to the signal traveling up to the satellite while down link refers to the signal coming from the satellite down to earth.
Any satellite is in a careful balance between gravity and inertia.
