It's because of inertia, Newton's 1st law of motion: Moving objects tend to keep moving. Also, there is very little friction at orbital altitudes, though there is some. Given enough time without extra power, sometimes years, the orbit will decay and the orbiting object will fall to Earth. Without interference though, it could orbit forever.

How is the power of the space shuttle measured?
In Thrust, the power of a normal launch is about 30 million newtons of Thrust to launch into orbit.
If a shuttle was in space could it shut off its thrusters to remain at the same speed?
Absolutely. That's what being in orbit means. As long as the Shuttle remains in orbit it uses no power. When it wants to come back to Earth. It uses its rocket engines to slow down, the it falls back to earth.
How long will a space shuttles fuel last?
The fuel supply of a space shuttle typically lasts for about 8.5 minutes after liftoff. During this time, the shuttle uses up the liquid hydrogen fuel and liquid oxygen fuel to power its main engines for the initial ascent phase before they are jettisoned.
What is difference between shuttle power loom and shuttle less power loom?
The shuttle looms require a shuttle which is quite expensive, require experienced labour, is comparatively slower, and the production is less and expensive. Whereas, shuttle less looms do not need a shuttle and hence are less expensive. the labour cost is also less since experience is not required, cloth production is faster and quieter, the quality of fabric is much better and these can produce a fabric with longer length and wider width.
Compare the the Saturn V rocket to Space Shuttle Why can't the shuttle travel to the moon?
The space shuttle was never designed to fly to the moon. The booster rocket for the shuttle did not have enough power to fly to the moon, as it was designed to launch the shuttle into low earth orbit. To enter Earth orbit a spacecraft needs to go 17,500 mph. To climb out of Earth's gravity well and fly to the moon, a spacecraft needs to go 24,000 mph. While those numbers seem close, they are not when it comes to rocket power. The shuttle would have needed many thousands of pounds more rocket fuel to launch to the moon and even more to turn around and come back home. The shuttle couldn't fly to the moon because it was never designed to do so. The Saturn V, on the other hand, was.
How do space ships get back without any fuel as they have used it up in space?
The Space Shuttle has enough residual fuel on board to fire it's main engines just long enoughto orient to the correct position and move out of orbit. From that point on, gravity takes over, and the shuttle glides all the way to the ground - one it leaves orbit, no engine power is used at all.
How were Apollo landings on earth different to space shuttle landings?
The Apollo capsule landings were planned to "splash down" in an ocean for recovery by an aircraft carrier standing by. The space shuttle landings more closely resemble a commercial aircraft landing. The space shuttle safely touches down on a runway.
What type of satellite provides power for shuttle missions?
Satellites don't provide power for space shuttles. The shuttle could receive power from the international space station, but besides that, the shuttle wouldn't take any power from any satellites.
Does a space shuttle have a battery?
Yes, a space shuttle has batteries onboard to provide power when it is not in direct sunlight or when solar panels are not providing power. These batteries are rechargeable and are used to power various systems on the shuttle.
How does a space shuttle receive electricity when in space?
The space shuttle receives electricity from its solar panels, which convert sunlight into electrical power. The solar panels are located on the surface of the shuttle and capture sunlight to generate the energy needed for the shuttle's systems and activities.
What makes a space shuttle lift off from earth?
power pure power
What types of fuel power the space shuttle?
fossil fuels
