Some spacecraft propulsion methods such as solar sails provide very low but inexhaustible thrust; [31] an interplanetary vehicle using one of these methods would follow a rather different trajectory, either constantly thrusting against its direction of motion in order to decrease its distance from the Sun, or constantly thrusting along its ...

Most spacecraft have some variety of rocket engine, and thus most research efforts focus on some variety of rocket propulsion, such as chemical, nuclear or electric. Spacecraft design – a specialized form of systems engineering that centers on combining all the necessary subsystems for a particular launch vehicle or satellite .
Space technology is technology for use in outer space. Space technology includes space vehicles such as spacecraft , satellites , space stations and orbital launch vehicles ; deep-space communication ; in-space propulsion ; and a wide variety of other technologies including support infrastructure equipment, and procedures .
The Swift spacecraft is an example of a spacecraft that does not have a propulsion subsystem. Typically though, LEO spacecraft include a propulsion subsystem for altitude adjustments (drag make-up maneuvers) and inclination adjustment maneuvers. A propulsion system is also needed for spacecraft that perform momentum management maneuvers.

The first test of electric propulsion was an experimental ion engine carried on board the Soviet Zond 1 spacecraft in April 1964, [16] however they operated erratically possibly due to problems with the probe. [17] The Zond 2 spacecraft also carried six Pulsed Plasma Thrusters (PPT) that served as actuators of the attitude control system. The ...
