L’essai du prototype Starship de SpaceX conclu par un crash<\/strong><\/p>\n\n\n\n

Le prototype Starship de SpaceX, la firme fond\u00e9e par l’homme d’affaires Elon Musk, s’est \u00e9cras\u00e9 alors qu’il tentait d’atterrir mercredi apr\u00e8s un lancement d’essai par ailleurs r\u00e9ussi depuis le centre de Boca Chica, au Texas, selon des images du test diffus\u00e9es en direct.<\/p>\n\n\n\n

La fus\u00e9e d\u00e9truite dans l’accident est un prototype auto-guid\u00e9 destin\u00e9 \u00e0 lancer le v\u00e9hicule de transport lourd que d\u00e9veloppe SpaceX pour emmener des humains et jusqu’\u00e0 100 tonnes de fret sur la Lune et sur Mars lors de futures missions.<\/p>\n\n\n\n

Elle a explos\u00e9 en touchant terre sur une piste d’atterrissage apr\u00e8s une descente ma\u00eetris\u00e9e.<\/p>\n\n\n\n

L’objectif de l’essai \u00e9tait d’atteindre une altitude de 41.000 pieds, gr\u00e2ce \u00e0 la premi\u00e8re utilisation de trois moteurs Raptor r\u00e9cemment d\u00e9velopp\u00e9s par SpaceX. La compagnie a maintenu le flou sur la r\u00e9alisation de cet objectif.<\/p>\n\n\n\n

Elon Musk a rapidement d\u00e9clar\u00e9 que \u00ab\u00a0la pression du r\u00e9servoir de carburant (de la fus\u00e9e) \u00e9tait basse\u00a0\u00bb pendant la descente, ce qui a provoqu\u00e9 une forte pression \u00ab\u00a0de la vitesse de descente\u00a0\u00bb.<\/p>\n\n\n\n

S’exprimant via Twitter, il a ajout\u00e9 que SpaceX avait obtenu \u00ab\u00a0toutes les donn\u00e9es\u00a0\u00bb souhait\u00e9es et d\u00e9crit la phase ascendante de la fus\u00e9e comme un succ\u00e8s.<\/p>\n\n\n\n
