// ORBITAL LOGISTICS AND PROPULSION TERM
Monopropellant
A monopropellant is a type of rocket fuel that doesn't need a separate oxidizer to burn; it decomposes on its own when heated or passed over a catalyst, producing hot gas for thrust.
TECHNICAL DEFINITION
A monopropellant is a chemical propulsion agent that, upon catalytic decomposition or thermal activation, releases energy and generates hot gas for thrust without requiring a separate oxidizer, commonly used in spacecraft for attitude control and station-keeping.
BACKGROUND
Private spaceflight companies include non-governmental or privately owned entities focused on developing and/or offering equipment and services geared towards spaceflight, both robotic and human. This list includes both inactive and active entities.

USAGE NOTE
Monopropellants offer simpler propulsion systems for small thrusters due to their single-tank design.
