n. The use of atmospheric drag to reduce the velocity of a spacecraft, especially so as to establish a stable orbit and to reduce fuel consumption
Wikipedia
Aerobraking is a spaceflight maneuver that reduces the high point of an elliptical orbit ( apoapsis) by flying the vehicle through the atmosphere at the low point of the orbit ( periapsis). The resulting drag slows the spacecraft. Aerobraking is used when a spacecraft requires a low orbit after arriving at a body with an atmosphere, and it requires less fuel than does the direct use of a rocket engine.
Usage examples of "aerobraking".
On that day the Chinese Heavenly Harmony ship arrived at Mars and began its aerobraking maneuvers.
His plan was to place a robot-controlled mass driver on an ice asteroid and push it into an aerobraking orbit around Mars, thus burning it up in the atmosphere.
