From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The kinetic energy dissipated by aerobraking is converted to heat, meaning that a spacecraft using the technique needs to be capable of dissipating this heat.

However, aerobraking is typically done with many orbital passes through a higher altitude, and therefore thinner region of the atmosphere. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The related techniques of aerocapture, aerobraking, and atmospheric entry also attempt to use the body's atmosphere to help reduce propulsion requirements. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. During these six months, aerobraking reduced the orbit period to between 12 and 6 hours. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This heat shield would then be jettisoned after aerobraking so the pilot could see, and safely land. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Generally aerobraking is used to circularize a highly elliptical capture orbit while minimizing the use of on board fuel. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. During descent, the orbiter passed through different layers of the atmosphere and decelerated from hypersonic speed primarily by aerobraking. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Only one pass in the atmosphere is required by this technique, in contrast with aerobraking. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Descent speed was reduced from 41,696 km/h to about 900 km/h by aerobraking. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Above the pressure sphere was a cylindrical antenna structure and a wide dish shaped structure that resembled an antenna but was actually an aerobrake. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It has been proposed for use during aerocapture and aerobraking. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. When aerobraking is done in this way, there is sufficient time after each pass to measure the change in velocity and make any necessary corrections for the next pass. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In order to land safely or enter a stable orbit the spacecraft must rely entirely on rocket motors since aerobraking is ruled out because the planet has very little atmosphere. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The word was probably coined as a whimsical adaptation of aerobraking, which is the process of slowing a space vehicle by the use of friction against a planet's atmosphere. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is an incredibly risky maneuver, one which they almost do not complete because they are about to use an aerobrake deployment system that is non-functional. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Since a gravity assist maneuver can change the speed of a spacecraft without expending propellant, if and when possible, combined with aerobraking, it can save significant amounts of propellant. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. These vehicles have used wings to provide aerobraking to return from orbit and to provide lift, allowing them to land on a runway like conventional aircraft.
