Le vaisseau spatial de Virgin Galactic atteint deux fois la vitesse du son

5/31/2018

Le SpaceShipTwo VSS Unity de Virgin Galactic a atteint une vitesse de près de deux fois supérieure à celle du son à 2 346,12 km / h lors de son deuxième vol d'essai mardi.

Les roquettes ont brûlé pendant 31 secondes et ont atteint une altitude de 34,8 km, a indiqué la compagnie. Fondée en 2004, Virgin Galactic vise à faire voyager les passagers vers l'espace, leur permettant de faire l'éxpérience de l'apesanteur.
