Therefore, the principle is met. Rocket motors are also used to propel spacecraft that are already in space. Thermal rockets use an inert propellant, heated by electricity (electrothermal propulsion) or a nuclear reactor (nuclear thermal rocket). Instead of sending out a single chunk of mass, the rocket fuel is burned continuously. This is, in fact, an example of rocket propulsion: the idea of propelling a vessel forwards by ejecting part of its mass in the opposite direction that we want to travel. Manuel Martinez-Sanchez Lecture 1: Introduction Types of Rockets (Engines) - Depending on gas acceleration mechanism/force on vehicle mechanism. A large fraction (typically 90%) of the mass of a rocket is propellant, thus it is important to consider the change in mass of the vehicle as it accelerates. A rocket (from Italian: rocchetto, lit.
