Ballistic capture

Ballistic capture is a technique used in the context of spacecraft navigation and orbital mechanics. It refers to the process by which a spacecraft is captured by the gravity of a celestial body (such as a planet or a moon) without the need for significant propulsion maneuvers. Instead, the spacecraft approaches the celestial body on a trajectory that allows it to enter into stable orbit due solely to the body's gravity. This technique is particularly useful for missions where fuel efficiency is crucial.
