Measures of how efficiently a rocket uses propellant and the engines that push spacecraft, from the Tsiolkovsky rocket equation, delta-v and specific impulse to the ion thruster. A concept belongs here when its cited article defines a propulsion measure or thruster type. Members are placed here from their own cited Wikipedia articles, each with a verbatim supporting quotation, so a reader can check why an entry sits in this group. The grouping forms part of the browse path for this section of the atlas.

The classical rocket equation, Tsiolkovsky rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity and can thereby move due to the conservation of momentum.
Specific impulse (Wikipedia)
Has Member: Specific Impulse, Lead sentenceQuote, Has Member: Specific Impulse, Lead sentence
Specific impulse (usually abbreviated as Isp) is a physical quantity defined as the ratio of change in momentum (impulse) to the mass used, usually fuel.
