Propulsion Module
A propulsion module is a component of a spacecraft that provides the necessary thrust to achieve and maintain the desired trajectory in space. It is responsible for accelerating the spacecraft from its initial position and velocity, and for making course corrections during the mission. Propulsion modules can use a variety of propulsion systems, including chemical rockets, ion thrusters, and nuclear engines. The choice of propulsion system depends on the mission requirements, such as the desired speed, duration, and payload mass. Propulsion modules are typically designed to be modular and replaceable, so that they can be swapped out for maintenance or upgrades without affecting the rest of the spacecraft.
