// ORBITAL LOGISTICS AND PROPULSION TERM
Gimbal
A pivoted support that allows an object, like a rocket engine, to rotate freely in one or more directions, enabling thrust vectoring for steering.
TECHNICAL DEFINITION
A mechanical mounting system, typically consisting of two or three concentric rings, that allows an object (e.g., a rocket engine, gyroscope, or camera) to pivot freely about an axis, providing angular motion control for thrust vectoring or stabilization.
BACKGROUND
The RS-25, also known as the Space Shuttle Main Engine (SSME), is a liquid-fuel cryogenic rocket engine that was used on NASA's Space Shuttle and is used on the Space Launch System.
