What is a deorbit burn that is done by space shuttles on reentry?
Wiki User
∙ 12y ago
The firing of a spacecraft's engine against the direction of motion to cut the spacecraft's orbital speed. The speed reduction places the spacecraft in a lower orbit. If this lower orbit passes through Earth's atmosphere, the spacecraft reenters.

How many hours is the re entry descent of a space shuttle after mission control gives the go'for deorbit burn?
5
Why do space shuttles need separate oxygen to burn the fuel in the space shuttle?
Answer: All combustion reactions require oxygen, since there is no oxygen in space, they must bring it with them.
Why is the space shuttle's nose round and not pointed?
The Space Shuttle's nose is round because if it were pointed, the nose, and then the rest of the craft, would burn up from reentry into the earth's atmosphere.
Do space shuttles use fuel?
Space shuttles use fuel when taking off and for control while in orbit, deorbiting, and landing. The main takeoff engines use liquid hydrogen and liquid oxygen, and there are two solid-fuel rocket boosters. In orbit, the shuttle uses thrusters that burn hydrazine and nitrogen tetroxide.
Why don't space shuttles burn when they enter the atmosphere?
There is heat resistent plating around the hull of the shuttle. The re-entry angle is also critical and needs to be as shallow as possible.

Why don't they launch space shuttles?
they could burn up or explode and caus emany deaths

Should you replace the space shuttle with a jet engine and carbon steel or provide stronger steel to jets to go into space?
A jet engine cannot take you into space as there is no air in space to provide the jet engine with oxygen. Also metals cannot survive reentry as they melt and burn up, unless protected by some type of heat shielding material..
What is the fuel used in space shuttles while landing?
The space shuttle only use the liquid fuel that is onboard to start the decent process. They burn their engines to slow down just enough for the earths gravity to begin pulling them back to earth. After that, they are simply big gliders.
Why does the space shuttle get very hot when entering the earth's atmosphere?
The space shuttle heats up when it enters the atmosphere because it encounters friction from the atmosphere. This is why the space shuttle is covered with special tiles that dissipates heat very quickly. You can hold a red hot one with the tips of your fingers. At the time of the deorbit burn the space shuttle is going 14,500 miles an hour. The atmosphere friction slows it down slow enough it open it's parachutes.
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.
Is burning of meteor in space due to friction?
Meteors do not burn in space. They burn when they dive throughEarth's atmosphere, because of friction with it.
Why are spaceship provided with heat shield?
Spaceships are provided with heat shields to protect them during exit and reentry of the earth's atmosphere. If they didn't have these shields, the ship would burn up.
