As we all know, spacecraft travel to a point in space designed to perform specific tasks in specific orbits in space are resources.

Bride Let’s explore their mobility.

Essentially, the gas created by the combustion of rocket fuel pushes the spacecraft in the opposite direction as it is ejected.

In addition, it is usually placed on the spacecraft to increase, decrease or change the direction of the velocity of the spacecraft moving in a balanced manner. Small propulsion systems or rotating wheels are used.

The small thrusters, which are mostly located in the front and rear of the space shuttles, allow the spacecraft to turn or change direction. Motion control systems are also Unlike the main engine, this one provides unidirectional and stronger thrust.

On the other hand, rotating wheels are used in many satellites and the Hubble Space Telescope.

These wheels are used in situations where the spacecraft needs to turn very precisely This allows the spacecraft to only orbit itself.

In this system, the principle of conservation of angular momentum is used and the wheels respond in such a way that the total angular momentum of the spacecraft system remains constant when it rotates in a certain direction. This The energy required to turn the wheels is supplied by solar panels.
