<strong>Propulsion</strong> is needed for launching of spacecrafts, for spacecraft orbit transfer as well as<br />
their orbit and attitude control.<br />
Here, only propulsion systems will be dealt with which are based on jet propulsion<br />
devices that produce thrust by ejecting s<strong>to</strong>red matter, called the propellant.<br />
Differences of launch and space propulsion have been mentioned.<br />
<strong>Propulsion</strong> subsystem requirements have been listed.<br />
Jet propulsion can be classified according <strong>to</strong> the source of energy utilized for the<br />
ejection of propellant: chemical, electric and nuclear.
