Le lanceur Falcon Heavy de SpaceX et la cabine Red Dragon cens\u00e9e se poser sur Mars en 2020 (SpaceX).<\/figcaption><\/figure>\n

Le premier vol priv\u00e9 vers Mars n\u2019aura pas lieu lors de la fen\u00eatre de tir de 2018, comme l\u2019avait annonc\u00e9 Elon Musk et sa soci\u00e9t\u00e9 SpaceX en septembre dernier. L\u2019entrepreneur avait d\u00e9cid\u00e9 de monter avec ses fonds propres une mission automatique de sa cabine propuls\u00e9e Dragon vers la plan\u00e8te rouge, avec atterrissage \u00e0 la clef\u2014l\u2019id\u00e9e \u00e9tant de renouveler l\u2019op\u00e9ration tous les deux ans. Mais la multiplicit\u00e9 des programmes dans lesquels s\u2019engage SpaceX et les retards de d\u00e9veloppement ont eu raison de cet ambitieux calendrier et le vol a \u00e9t\u00e9 report\u00e9 \u00e0 2020.<\/p>\n

C\u2019est en particulier l\u2019int\u00e9r\u00eat de deux touristes millionnaires pour un vol vers la Lune fin 2018, utilisant le m\u00eame lanceur Falcon Heavy et la m\u00eame cabine Dragon, et qui serait un vol payant, qui a sans doute motiv\u00e9 en partie ce glissement de calendrier. D\u2019autant que la NASA, principal client de SpaceX, verrait d\u2019un mauvais \u0153il que leur prestataire se disperse dans autant de projets, alors qu\u2019elle compte \u00e0 juste titre \u00eatre prioritaire dans le d\u00e9veloppement, les tests et la mise en service du Dragon pour emporter ses propres astronautes vers la Station Spatiale Internationale, \u00e9galement fin 2018. Quant au lanceur n\u00e9cessaire \u00e0 ces op\u00e9rations\u2014le Falcon Heavy de SpaceX\u2014son vol inaugural n\u2019aura lieu que cet \u00e9t\u00e9\u00a0: tout probl\u00e8me majeur lors du test ferait de nouveau glisser le calendrier.<\/p>\n

Avec ses 6 tonnes, le vaisseau Red Dragon de SpaceX sera le plus lourd engin jamais pos\u00e9 sur Mars (SpaceX).<\/figcaption><\/figure>\n

Ce n\u2019est que partie remise, en 2020 donc, pour la tentative d\u2019atterrissage sur Mars de la lourde cabine Dragon, pesant pr\u00e8s de 5 tonnes \u00e0 vide, plus 1 tonne de fret \u00e0 d\u00e9finir, soit six fois plus que le plus lourd des engins pos\u00e9s \u00e0 ce jour sur Mars\u00a0(la tonne que repr\u00e9sentait la sonde Curiosity de la NASA). Du coup, 2020 sera un cru exceptionnel pour l\u2019exploration de Mars avec la m\u00eame ann\u00e9e les missions d\u2019atterrissage Dragon de SpaceX, Mars Rover 2020 de la NASA (le jumeau am\u00e9lior\u00e9 de Curiosity), l\u2019ExoMars de l\u2019Agence Spatiale Europ\u00e9enne, et un atterrisseur Chinois avec sa propre automobile\u00a0!
