When in space, the purpose of a propulsion system is to change the velocity, or v, of a spacecraft. [6] In-space propulsion begins where the upper stage of the launch vehicle leaves off, performing the functions of primary propulsion, reaction control, station keeping, precision pointing, and orbital maneuvering.
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 .

JPL and the Space Age was created in 2022 [2] to inform users about JPLs contributions and missions. JPL and the Space Age started airing on NASA TV and JPLs website. The first episode released for the franchise was The American Rocketeer, releasing in January of 2022. [3] The series later migrated to NASA+ in November 2023. [4]
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 ...
