CONT

Le freinage atmosphérique (ou aérofreinage) est une technique économique qui consiste à utiliser l'atmosphère d'une planète pour modifier l'orbite d'une sonde spatiale. En général, on utilise l'aérofreinage pour circulariser une orbite et diminuer sa période de révolution (c'est à dire le temps mis par la sonde pour boucler un tour).
