Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry.

Mar 14, 2024 · In-space propulsion devices for small spacecraft are rapidly increasing in number and variety. Although a mix of small spacecraft propulsion devices have established flight heritage, the market for new propulsion products continues to prove dynamic and evolving.

Nov 20, 2023 · Propulsion System. There are four major components to any full-scale rocket: the structural system, or frame, the payload system, the guidance system, and the propulsion system. The propulsion of a rocket includes all of the parts which make up the rocket engine, the tanks pumps, propellants, power head and rocket nozzle.

Jan 24, 2025 · Space nuclear propulsion draws energy from atomic fission reactions instead of traditional chemical reactions, thus providing comparatively unlimited energy and opening the door for robust and enduring access throughout the solar system.

Apr 17, 2023 · Designing and testing chemical propulsion systems and nuclear thermal engines for satellites and spacecraft, in support of NASA’s space exploration missions.

Jan 25, 2023 · As NASA takes its first steps toward establishing a long-term presence on the Moon’s surface, a team of propulsion development engineers at NASA have developed and tested NASA’s first full-scale rotating detonation rocket engine, or RDRE, an advanced rocket engine design that could significantly change how future propulsion systems are built.

Jan 23, 2025 · Space Propulsion. We focus on research and technology for flight demonstration components and systems for spacecraft propulsion systems, propulsion stages, and cryogenic fluid flight systems. Our research and technology development enables new space exploration capabilities as well as increased reliability, safety, and affordability.

Apr 23, 2024 · Small spacecraft using the NASA-H71M electric propulsion technology will be able to independently maneuver from low-Earth orbit (LEO) to the Moon or even from a geosynchronous transfer orbit (GTO) to Mars.

Advanced in-space propulsion technologies will enable much more effective exploration of our Solar System and will permit mission designers to plan missions to “fly anytime, anywhere, and complete a host of science objectives at the destinations” with greater reliability and safety.

Aug 6, 2024 · In-space propulsion systems are used to put and maintain satellites into position or send spacecraft further into space. The work to test and develop these propulsion systems is just as significant as launch systems and is increasing in scope and scale.
