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.

A satellite or spacecraft orbiting the earth or traveling through the solar system encounters very small forces. For this reason, many satellite propulsion systems must deliver very precise ``impulse bits'' in order to accurately control the position or attitude of these objects.

Mar 14, 2024 · The FPPT can provide a large total impulse primary propulsion for micro-satellites through implementation of a novel PTFE fiber propellant storage and delivery mechanism. A major enhancement of the FPPT technology over classical PPTs is the ability to control both the propellant feed rate and pulse energy, thereby providing control of both the ...

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.

New conceptual and design solutions are suggested for small satellite propulsion with respect to its specific constraints and requirements. Features of future advanced, low-cost propulsion system for small satellite are

There are many SmallSat propulsion system and thruster options at various stages of development currently available in the commercial market. The technologies consist of a wide range of propulsion system types: chemical (e.g., cold gas and green), electric, solids, and non-propellant (e.g., solar sails and tethers).

Sep 26, 2017 · SmallSats enable low-cost access to space. Their uses and capabilities are growing to the point where a propulsion system is required. Current state-of-the-art for SmallSat propulsion systems is rapidly evolving. However, their …

Oct 19, 2021 · This topic page covers the design of propulsion subsystems for small satellites. This includes design of subsystem components; selection of commercial off-the-shelf (COTS) components; and integrated design, configuration, and sizing of the complete subsystem.

Dec 18, 2023 · Satellites utilize different propulsion systems to maneuver in space after launch. The three main categories of in-space propulsion are chemical, electric, and nuclear thermal propulsion. There are also some more speculative technologies that …

1 day ago · Chemical in-space propulsion systems, used in orbital systems such as satellites, space tugs, and space probes, generally do not have high acceleration requirements like launch vehicles. For orbital change manoeuvrers of satellites and cargo modules, thrust levels are considerably lower, typically ranging from 10 N to 1000 N, with re ...
