What is aerobraking? Aerobraking - Wikipedia Aerobraking - Wikipedia Aerobraking - Wikipedia Aerobraking - Wikipedia Aerobraking is a spaceflight technique wherein an orbiting spacecraft brushes against the top of a planetary atmosphere . The friction of the atmosphere against the surface of the spacecraft slows down and lowers the craft's orbital altitude. 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. During aerobraking the spacecraft used friction from the Martian atmosphere to slow down and to trim its initial 35-hour elliptical orbit around the red planet to a two-hour near-circular orbit. The final orbit was more suitable for science operations and ideal for making highly detailed observations of the surface. Aerobraking is a way of slowing down a spacecraft by using the atmosphere or outer gas layers of a planet . The ship "dips" into the atmosphere. As it does that the molecules of gas in the atmosphere rub against the ship. This acts as resistan...
