Rockets are much faster than airplanes as rockets have much more thrust than airplanes do.
Rockets can travel as fast as 18,000 miles per hour and planes travel around 768 mph.
Rockets even fly faster than fighter jets.
A rocket has more thrust than an airplane because rockets actually carry their own oxidizer and is able to generate high thrust even in a vacuum, while the airplanes rely on atmospheric air in order to create their thrust and limits the planes power when compared to rockets.
Rockets produce a greater amount of thrust that is relative to their mass as rockets have a much higher to thrust to weight ration than airplanes.
The reason rockets don't use jet engines is because jet engines require atmospheric oxygen to operate and run.
Rockets need to function in the vacuum of space and in space there is no air so instead rockets carry their own oxidizer to burn with their fuel and allow the jet engine to generate thrust even without atmospheric oxygen.
A jet engine breathes in air to create it's thrust and operate and because space has no air the jet engine cannot breathe that air that it needs.
Propulsion works in space even if there is no air on a principle called reaction mass which is what generates the thrust by expelling the hot gases from the spacecrafts engines.
Propulsion does work in space as spacecraft and rockets use a propulsion method and principle called reaction mass which generates thrust by expelling hot gases from their engines.
This is what propels them forward even in the vacuum of space and is based on Newton's Third Law of Motion.
The force of the expelled gases push the spacecraft in the opposite direction and allows for movement without requiring air to push against.
Turbine engines and normal propellers use air from the atmosphere as their working fluid, however rockets use the combustion exhaust gases.
And in out space there is no atmosphere so normal turbines and normal propellers don't work in space.
This is why rockets work in space but turbine engines and propellers don't work in space like they do on earth.
The fuel that satellites use is hydrazine based fuel which is the satellites primary propellant.
However research is ongoing to develop a less toxic fuel due to it's highly toxic nature.
Hydrazine based fuel is often used for stationkeeping maneuvers and orbital adjustments.
Once the satellite is in it's position above earth in space the satellite requires a method of propulsion to make sure the satellite can move if it needs to.
The satellite also needs to be able to avoid space debris and compensate for drag over time as well as be able to de-orbit itself after the mission is over.
The satellites use a highly toxic hydrazine based fuel for this propellant fuel.
Hydrazine based fuel is a type of highly toxic propellant that uses hydrazine (N2H4) as its primary fuel source, commonly used in rocket propulsion systems due to its high energy density, stability, and ability to ignite spontaneously when exposed to a catalyst, making it ideal for applications like satellite thrusters and spacecraft maneuvering.
While hydrazine based fuel is a great fuel source for satellites in space, hydrazine is highly toxic and requires strict handling procedures due to its hazardous nature
