  • La fusée Falcon Heavy de Space X le 11 avril 2019 à Cap Canaveral

Le lanceur lourd de Space X a décollé hier depuis le pas de tir de Cap Canaveral en Floride à 18h36 heure locale dans le but d'aller placer en orbite le satellite Arabsat-6A. Selon le site américain Ars Technica, cela pourrait se faire en utilisant la fusée Delta IV Heavy de la United Launch Alliance, la Falcon Heavy de SpaceX ou bien une combinaison des deux - une option qui serait assez surprenante, a-t-il cependant indiqué.

Il s'agit du second lancement de Falcon Heavy. Cette opération doit intervenir environ 34 minutes après le décollage. "Réussite du déploiement d'Arabsat-6A en orbite géostationnaire confirmée -fin de la première mission commerciale de Falcon Heavy", a rapidement tweeté SpaceX.

She then added that her "love and commitment to our country and that of my colleagues should never be in question". What Crenshaw has done: Crenshaw is a retired Navy Lieutenant Commander who served as a Navy SEAL.

L'objectif de la société est également de récupérer sur Terre les trois suramplificateurs de la fusée: deux sur la terre ferme (environ 8 minutes après le décollage) et le troisième sur la barge stationnée dans l'océan Atlantique baptisée " Of course I still love you " près de dix minutes après le décollage. Space X et le constructeur automobile appartiennent à l'homme d'affaires Elon Musk. "Falcon" signifie "faucon" en anglais. Pour le premier, en février 2018, qui était un vol d'essai, la charge était la Tesla rouge du patron de SpaceX, Elon Musk, avec un mannequin baptisé Starman à bord (la voiture reste en orbite autour du Soleil, entre la Terre et Mars). Ces boosters devraient servir - au moins en partie - à assurer une prochaine mission de l'entreprise. SpaceX récupère en effet régulièrement le premier étage de son lanceur afin de le réutiliser pour réduire nettement les coûts de lancement.

Le Falcon Heavy est essentiellement composé de 3 lanceurs rattachés ensemble et disposant chacun de la puissance d'une fusée Falcon 9.
