SpaceX is taking reservations for Mars.
You may think that you’ve already heard this news before. One month ago (almost to the day), Elon Musk famously penciled in “2018” as the date SpaceX will launch its first Red Dragon space capsule to Mars. Specifically, the company will use its new Falcon Heavy lift vehicle to carry a specially designed Dragon 2 spacecraft to Mars, then land said capsule vertically on the Red Planet, firing SuperDraco thrusters to brake its descent.
From that position, SpaceX’s Red Dragon would theoretically be able to relaunch from Mars, where the gravity is less than 38% of Earth normal, and return to Earth — fuel permitting. (That’s not Musk’s plan, however. He’s running this mission himself, and paying out of pocket, just to collect information in preparation for subsequent manned and unmanned missions to Mars.)
