AEROBRAKING Meaning and
Definition
-
Aerobraking is a technical term used in the fields of astrodynamics and space exploration, referring to a maneuver or process used to slow down or change the trajectory of a spacecraft by utilizing atmospheric drag. It involves intentionally dipping into the atmosphere of a celestial body, such as a planet or moon, to decelerate the spacecraft.
During aerobraking, the spacecraft enters the planet's atmosphere at a precise angle and velocity, causing it to interact with the atmospheric gases. This interaction generates drag forces that oppose the spacecraft's motion and gradually reduce its velocity. As a result, the spacecraft's orbit is elongated or its inclination altered, allowing for orbital changes or efficient slowing down.
Aerobraking is typically utilized in space missions to conserve fuel and minimize the energy required to achieve a desired orbit. It is particularly valuable when exploring other planets or moons, where gravity assists and precise maneuvers are necessary. The technique is often employed by interplanetary missions to fine-tune their orbits, adjust trajectories, or even enter into stable orbits around a celestial body.
Despite the advantages and fuel savings offered by aerobraking, it also poses challenges due to the extreme heat generated by atmospheric friction. Special heat shields or thermal protection systems are required to protect the spacecraft from the intense heat as it travels through the atmosphere. Nevertheless, the benefits of aerobraking make it a valuable technique in space exploration and mission planning.

Etymology of AEROBRAKING
The word "aerobraking" is a compound word derived from two roots: "aero-" and "braking".
1. "Aero-" is derived from the Greek word "aēr" which means "air". It is commonly used as a prefix in scientific and technical terms related to air or aviation, indicating a connection with the air or the atmosphere.
2. "Braking" originates from the verb "to brake", which has Old English roots from the word "brecan", meaning "to break". In the context of aerospace and space exploration, "braking" refers to the act of using friction or drag to slow down a spacecraft or a vehicle entering an atmosphere.
Combining these two roots, "aerobraking" refers to the process of using atmospheric drag or air resistance to slow down a spacecraft or an orbital object, reducing its velocity and altering its orbit.
