The same way they prevent the moon from falling to earth . . . give it enough horizontal speed
so that by the time gravity has pulled it down 10 feet, the surface of the earth has curved down
10 feet, so it's still just as far from the surface as it was originally.
Perform this maneuver enough times, and the moon "falls" through a complete circle around
the earth, without ever getting any closer to it.
And scientists have nothing to do with it.

∙ 11y agoNothing, nothing at all! That is exactly why It is called Free Fall.
The International Space Station, or ISS, is in constant free fall about Earth; just we have to keep in mind that Earth's surface is falling away down from underneath them at the same rate or pace.
Such is the Nature of Orbital Velocities: the ISS is in a low Earth orbit. If Earth was a peach, the Space Shuttle's and the ISS's orbit would be [still] in the fuzz; and they orbit Earth once each 90 minutes.
The Next Step Out is the GEO-SYNCRONOUS Orbit: there it sits- 22,400 kilometers above Earth's surface - it's 'period of rotation' around Earth and It's surface is identical to that of Earth's rotation around It's Own Axis; meaning that any satellite at this orbital height will remain looking down at the same point on Earth's surface indefinitely.

∙ 12y agoThere isn't any such force. That's why a satellite is constantly falling. But it's also
moving "sideways" ... fast enough so that in the time it takes it to fall 1 mile,
the surface of the Earth also curves down by 1 mile. So the satellite never gets
any closer to the Earth, and continues to fall in a circle that follows the curve of
the Earth.

Why do you need astronauts?
so we can keep our satellites running
Why are three of Saturn's satellites Atlas Prometheus and Pandora called shepherd moons?
They keep Saturn's rings in order.

What two ways the sun holds earth in orbit because of?
There are two factors at play when we are looking at satellites orbiting around another object. The same applies for a man made satellite in orbit around earth or another planet, a moon (natural satellite) in orbit around a planet, or the planets themselves orbiting around the sun. There is the satellites the tangential velocity acting away from the system and the gravitational attracting keeping the bodies close together. The satellites have a tangential velocity, they are speeding along sideways relative to the Earth (for example). If there was no gravity, this velocity would take the satellite away from the Earth, but the Earth has a gravitational force which counteracts this effect. The Earths gravitational force is constantly attracting the satellites in, against this tangential velocity. If the satellites were to slow down, then they would eventually spiral into the Earth, but in orbit there is very little drag, so the satellites pretty much maintain their speed and their orbits, though they do need a boost occasionally to keep them in orbit due to the small amount of atmospheric drag over time.
Is there gravity where satellites are at?
Yes there are enough gravitational forces to keep the satellites orbiting earth.
How does satellites work?
they work by the people on earth they use a control button to keep the satellites working
How slow can you go on reentry to earth?
This depends upon how much fuel you are prepared to burn to oppose the force of gravity. Even the ordinary satellites are falling towards the Earth, and require a periodic thrust (burn) to keep them in orbit. Unfortunately, the attraction due to gravity depends on mass, so most of the space junk just stays up there, whereas the orbiting satellites need an occasional burn to keep them there.
Why don't satellites crash if gravity is attracting them towards the center of the earth?
Because they are in orbit which means they have enough forward motion to keep them into a state of "Free Fall". A satellite is falling to earth's center due to gravity. But for every inch it falls toward earth, earth move out of it's way by one inch.
What does the gravitational pull of the earth keep around it?
The moon, satellites, international space station, and everything else orbiting the earth.
If you fall off the face of the earth will you keep falling forever?
No, the earth is round as far as I know
What two forces keep the moon and all other satellites in orbit around earth?
Gravity and Inertia
How are hurricanes identified?
Usually, they find you all by themselves. Otherwise, meteorologists keep an eye on what's going on in the earth's weather patterns and notice when a big wind is on its way, and let us know.
How does gravity keep the moon in orbit earth?
The moon is falling, but since the Earth's gravitational pull is constantly acting on it, the moon keeps falling but it is moving towards the Earth so it move in an egg shaped motion.
What are examples of solar satellites?
In one sense all the planets are solar satellites, that is, they orbit the sun, just as the moon is Earth's satellite. So Mars, Venus, Earth and all the planets are solar satellites.In another sense a solar satellite could be any of Earth's artificial satellites, because most of them use solar panels to generate the electricity they need to keep sending data back to Earth.
Why do camras on earth cam keep going temporary unavailable?
cameras on Earth Cam may go temporarily unavailable due to satellites being blocked for short periods of time as the Earth moves in space.
Why does the moon not crash on earth but stay in space and not float away or into earth?
The moon and other planets and their satellites are held in space by the force of gravity from other planets and satellites. If the moon tried to drift off into space, gravitational forces from the Earth will keep it from floating away. It doesn't crash into the Earth because planets and moons pull AGAINST each other and keep each other from drifting away.* * * * *Only partly true.The moon does not float away because of the action of earth's gravity - whether you view this as a force or a distirtion of space-time in the moon's path.The moon does not crash into the earth, not because of other planets or satellites, but because of the momentum of its orbit around the earth.
