/ˈɛroʊˌbreɪkɪŋ/,

/ˈɛrəˌbreɪkɪŋ/

Origin: Formed within English, by compounding. Etymons: aero- comb. form, braking n.

Etymology: < aero- comb. form + braking n. Compare earlier aerodynamic braking n. at aerodynamic adj. Compounds. Compare also later aerobrake n., aerobrake v.

Astronautics.

Aerodynamic braking of a spacecraft when it passes repeatedly through the upper layers of a planet's atmosphere, esp. when brought about in order to enter or alter its orbit round the planet.
