Spacecraft propulsion refers to how a space vehicle achieves forward movement. As there is no medium in space such as air, wings and fins are ineffective at maneuverability; electric thrusters may provide assistance instead. A rocket propels itself by pushing on the gas that ignites from its engines – this is a straightforward scientific fact […]
Spacecraft electric propulsion uses solar array power to ionize and accelerate inert gas propellants like Xenon (no, not from Superman’s home planet) for propulsion by Hall and gridded ion thrusters that gradually speed the spacecraft along its journey. EP systems possess very high specific impulse, or the amount by which a change in speed alters
Propulsion systems are usually the most complicated and expensive components of spacecraft. To maximize its potential, it is crucial that we understand their capabilities. This survey foregoes direct technology maturity assessments (TMAs) using NASA’s TRL scale, acknowledging its complexity is challenging to perform accurately without sufficient in-depth technical insight into individual devices.

Propulsion systems play an essential role in any mission’s success, enabling spacecraft probes to change their velocity in space and, if needed, escape Earth’s gravity. Spacecraft thrust is determined by the rate of acceleration. Due to conservation of momentum, small accelerations applied over a longer time can generate equal force as greater forces applied quickly.
Spacecraft must withstand and operate successfully in the harsh environment of outer space, necessitating structural subsystems that can support any forces generated during launch and ascent of its rocket engine. Spacecraft require propulsion systems in order to change their trajectory and maneuver around space, as well as power sources, communications devices and payload capabilities in
