Like any other satellite, including the Moon, it stays up by centripetal force. Like a weight being whirled around your head on a string it would fly off in straight line if the force holding it in were to disappear. With the weight, this force is the tug of the string. With the space station it's gravity. The speed of the space station is just sufficient to keep it from falling to Earth, but also not so great that it would fly off into space.
If the speed of the space station were to drop, it would fall to Earth.
Satellites stay up in orbit because of their speed. A satellite in orbit about 300km above earth must travel at a speed of 28,000 km/h to stay in space. This speed is called its orbital velocity.
The mutual force of gravitational attraction between the satellite and the planet prevents the satellite from taking off in a straight line. The satellite is continuously falling towards the earth like any thrown object but its velocity is such (and the Earth curves away under it) that it continuously misses the ground
Orbiting bodies are held together by the mutual force of gravitation between them.
Without gravity, the Earth would go sailing away from the Sun in a straight line.
Similarly, the moon would go sailing away from the Earth, and would never be
seen again.
The gravitational pull of Earth is the main factor that a rocket must overcome. A rocket must reach a certain velocity or speed and direction to orbit or escape the Earth. For a rocket to orbit the Earth, it must have enough thrust to reach orbital velocity. Orbital velocity is the speed and direction a rocket must travel in order to orbit a planet or a moon. The lowest possible speed a rocket my go and still orbit the Earth is about 8km/sec. If the rocket goes any slower, it will fall back to Earth.For a rocket to travel beyond Earth orbit, the rocket must achieve escape velocity. Escape velocity is the speed and direction a rocket must travel to completely break away from a planet's gravitational pull. The speed a rocket must reach to escape the Earthis about 11km/sec.
If its headed for the moon or a planet it goes there but generally they go into orbit (for a while at least).
Rockets usually use two or three stages to get into space. The first stage usually drops into the ocean or burns up in the atmosphere, the upper stages will either burn up or go into orbit around the earth. The upper stages may stay in orbit forever, upper stages from the Saturn V moon rocket are still in orbit, creating an orbital debris hazard. On the space shuttle, the solid rocket boosters fall back into the ocean for recovery and the external fuel tank disintegrates in re-entry.
If a rocket needs to deliver it's payload beyond earth orbit, it will usually be equipped with an upper stage called a centaur. The centaur will detach from the satellite or space probe when it is in the desired orbit. One exception to this was when the LCROSS spacecraft stayed attached to its centaur and used it to crash into the moon on a mission to study lunar dust.
Satellites use centrifugal force which at a certain height balances out with gravity.
Rockets leaving space have to have enough thrust to escape Earth's gravity.
Its becuase of the sun gravity
to go to space
It was a German rocket in 1944.
the pressure from the the rocket's fuel thingy makes the rocket go up. pretty soon, the rocket is in space.
Saturn rocket
to get to the moon or just for fun
to go to space

space :)
with a rocket ship?
Saturn rocket
In a big enough rocket.
2011
u will meet jirachi when the rocket count reaches 100 and u go into space,
Iwouldtake a rocket 8 to 9 minutes to go to space.
it lets you orbit around space and go back to earth safely
