Definition
Spacecraft Propulsion – The action or process of imparting motion to a spacecraft by means of a force such as a thrust of air or energy released by burning fuel. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.
Spacecraft Power Supplies – Sources of electrical energy, including batteries, generators, and energy conversion devices, that support the normal operation of spacecraft. NASA Thesaurus, Washington, DC: National Aeronautics and Space Administration.
NASA Interest
Exhaustive Interest : All chemical, electric, magnetohydrodynamic, hybrid, or other types of energy conversion suitable for propulsion or stationkeeping of spacecraft, satellites, space probes, planetary probes, space stations, and lunar probes; and for use as auxiliary power sources for spacecraft; including liquid rocket engines, solid rocket engines, ion engines, plasma rocket engines, electric rocket engines, etc., including their components.
Selective Interest : Propulsion and mobile or stationary power sources for earthbound use or transportation, e.g., ship, locomotive, automobile, aircraft, and truck propulsion; mobile or stationary electric power plants, unless directly applicable to spacecraft use.
