propulsion. n. 1. the act of propelling or the state of being propelled. 2. a propelling force. [C15: from Latin prÅpellere to propel].
Thrust from photons emitted from a laser array could be used to propel a spacecraft. All spacecraft operate by firing propellant in the opposite direction to the way they want to travel. Traditionally this propellant is fuel and has to be carried on board the spacecraft, making it heavier and slowing it down.
