vitesse parabolique

Explanation:
Vitesse qu'on doit imprimer à un engin spatial pour qu'il s'affranchisse de l'attraction de l'astre d'où il est lancé. Cette vitesse est de 11 180 m/s sur la Terre et de 10 846 m/s à 400 km d'altitude. L'engin décrit alors une parabole, c'est-à-dire une sorte d'ellipse dont l'un des foyers est fixe et dont l'autre est théoriquement rejeté à l'infini.
