Par rapport \u00e0 la version pr\u00e9c\u00e9dente, le projet de lanceur qu\u2019il a red\u00e9fini\u2014d\u00e9voil\u00e9 en octobre 2018 au Congr\u00e8s International d\u2019Astronautique\u2014fait \u00e9tat d\u2019un vaisseau spatial ou \u00ab\u00a0navette\u00a0\u00bb (BFS pour “Big Falcon Spaceship”) de 55 m\u00e8tres de long, contre 48 m\u00e8tres pr\u00e9c\u00e9demment. Il sera \u00e9quip\u00e9 de sept moteurs Raptor \u00e0 m\u00e9thane et oxyg\u00e8ne liquide (plut\u00f4t que six), l\u2019id\u00e9e \u00e9tant de pouvoir transporter 100 astronautes d\u2019un coup vers la Lune ou vers Mars, l\u2019habitacle ne mesurant pas moins de 1000 m\u00e8tres cubes, soit le volume habitable d\u2019un Airbus A380. Et on notera l\u2019apparition d\u2019un troisi\u00e8me aileron \u00e0 l\u2019arri\u00e8re\u2014ailerons qui serviront \u00e9galement de pieds d\u2019atterrissage, Elon Musk pr\u00e9cisant qu\u2019il avait \u00e9t\u00e9 influenc\u00e9 dans ce choix par la belle sym\u00e9trie de la fus\u00e9e d\u2019Herg\u00e9, dans l\u2019Objectif Lune\u00a0de Tintin\u00a0: \u00ab\u00a0J\u2019adore le design de la fus\u00e9e de Tintin\u00a0\u00bb, a avou\u00e9 l\u2019entrepreneur, \u00ab\u00a0donc j\u2019ai voulu me rapprocher de son concept. Si vous avez un doute, faites confiance \u00e0 Tintin\u00a0!\u00a0\u00bb<\/p>\n

Quant au premier \u00e9tage qui lancera l\u2019engin, \u00e9quip\u00e9 de 31 moteurs Raptor, il d\u00e9veloppera une pouss\u00e9e de 5400 tonnes au d\u00e9collage, soit presque deux fois la pouss\u00e9e de la Saturn\u00a0V des vols Apollo.\u00a0Musk estime le coup de d\u00e9veloppement de l\u2019engin entre 5 et 10 milliards de dollars, et les tests de la partie Navette doivent commencer d\u00e8s l\u2019an prochain, courant 2019.<\/p>\n

La grande nouvelle est que le premier exemplaire de la fus\u00e9e compl\u00e8te devrait voler d\u00e8s 2023 autour de la Lune avec \u00e0 son bord le m\u00e9c\u00e8ne japonais Yuasaku Maezawa qui a pr\u00e9-achet\u00e9 le premier exemplaire de l\u2019appareil.<\/p>\n

Quant \u00e0 des vols habit\u00e9s vers Mars, Elon Musk avait autrefois fait \u00e9tat de dates similaires\u00a0: 2022 pour un premier vol automatique\u00a0; 2024 pour un premier vol pilot\u00e9\u00a0; il a aussi d\u00e9sormais annonc\u00e9 la date de 2028 pour le d\u00e9but de la construction d\u2019une base martienne. Musk est coutumier des effets d\u2019annonce et de calendriers tr\u00e8s optimistes. Affaire \u00e0 suivre, car avec le g\u00e9nial entrepreneur, on n\u2019a en tout cas pas le temps de s\u2019ennuyer\u2026<\/p>\n","protected":false},"excerpt":{"rendered":"
