Interestingly enough the sattelites are doing their level best at falling from the sky. The whole idea is that at orbital velocity the objects move forward fast enough that they continously miss the Earth as they fall down.
In the ideal case satellites are in orbit. This means that they circle the Earth at a specific speed and a specific height. Because satellites aren't in Earth's atmosphere nothing slows them down. If they did slow down it would reduce the height they orbit at. If the height were reduced they would encounter thicker air which would slow them down more, which would lower their height more. This cycle would continue until they crashed.
In actuality the satellites do slow down very slowly because the air is not totally absent. Eventually all satellites will fall from the sky.

What happens to old satellites?
Old satellites orbiting near the Earth eventually fall back into the atmosphere and burn. Satellites orbiting farther away stay in orbit indefinitely.
What does dipolarity have to do with snowflakes?
Snowflakes are shapes of snow that fall from the sky.
What are the name of satellites of planet Mercury?
There are no known satellites of Mercury.
What is a geostationary satellite State two uses of a geostationary satellite?
In order for a satellite to stay in space and not fall to earth, it has to move in orbit round the earth. Many satellites and the International Space Station are in low orbit and at that distance above the earth orbit the earth in a couple of hours or so. However, if the orbit is around 26000 miles up, then at that distance the time it takes for a satellite to freely orbit is exactly one day or 24 hours. This means that the satellite is always above the same spot on earth, as the earth also takes 24 hours to rotate. Thus, if we could see the satellite in the sky it would not move across the sky like the International Space Station but it would stay in the same place in the sky. This means that they can be used for communication - when you telephone, say, from Europe to the USA then the signals are received by these satellites, amplified and relayed across the world to the receiver of the call. As the satellites are in the same place in the sky all the time, you can call at any time of the night or day. However, if the satellite moved across the sky in low orbit you would only be able to use it when it was in the sky - in other words you could only telephone for a few minutes at a time and then have to wait until it was back in the sky again. Similarly, these satellites are used for navigation in sat-navs. As the satellite is always in the same point in the sky, it can work out your position at any time of the night or day. The term 'geostationary' comes from 'geo' meaning 'earth' (as in geo-graphy, geo-thermal etc) and 'stationary' - meaning not moving i.e. the satellite is 'not moving above earth'.
How do satellites triangulate?
Triangulation of satellites requires three satellites that bank of one another simultaneously.
How many satellites fall from the sky?
about a 100 basket-ball sized satelittes fall every year.
What can cause satellites to fall out of the sky?
Satellites may fall out of the sky because they get too close to Earth. In that case, Earth overwhelmed the power of the satellite's propelling system and slowly but surely dragged the satellite into the Earth's atmosphere.
How many satellites in sky?
about 3,000
Do satellites move fast in the sky?
No they don't move fast in the sky

Why did the sky fall?
the sky never did fall and it never will the sky can not fall. it is impossible! they sky is made up of gasses. gass can not fall. so do not worry about the sky falling. it is just a myth.
Do satellites in orbit around Earth continuously fall toward earth?
Satellites orbit the earth for a few years then fall to earth however they are directed to fall to the sea
Is the sky about to fall apart?
No, the sky will never fall apart.

How many satellites needed to get a position?
You need 4 to locate a position. There are 24 satellites in use in the sky with 8 spares.
Could the sky really fall?
No things can fall from the sky though.
