Le vaisseau Dragon \u2014celui-l\u00e0 m\u00eame qui transportera des astronautes dans un proche avenir (peut-\u00eatre d\u00e8s l\u2019an prochain) vers la Station Spatiale Internationale\u2014est un v\u00e9hicule de huit tonnes qui pour le moment transporte du fret (jusqu\u2019\u00e0 deux tonnes) vers la Station. C\u2019est sans doute \u00e0 vide qu\u2019il se poserait sur Mars lors de la mission de 2018, l\u2019objectif \u00e9tant de tester l\u2019atterrissage d\u2019un \u00ab poids lourd \u00bb sur la plan\u00e8te rouge, ce qui n\u2019a encore jamais \u00e9t\u00e9 accompli (la plus lourde charge utile \u00e0 ce jour, Curiosity, n\u2019atteignait pas la tonne). L\u2019engin de Space-X va pour ce faire utiliser ses moteurs-fus\u00e9e en r\u00e9tropropulsion supersonique.<\/p>\n

D\u2019autant que Space-X et son pr\u00e9sident Elon Musk d\u00e9clarent haut et fort qu\u2019ils encha\u00eeneront les missions \u00ab Red Dragon \u00bb vers Mars tous les deux ans, \u00e0 chaque fen\u00eatre de tir vers la plan\u00e8te rouge.
