The billionaire's rocket company, SpaceX, is getting tantalizingly close to developing reusable rockets and a whole suite of spacecraft destined for the Red Planet.
It's already successfully tested models of its Dragon space capsule - a vessel designed specifically for shuttling cargo and eventually astronauts to the International Space Station. If Musk has his way, a more advanced model, called Red Dragon, will carry the first humans to Mars.
On Sept. 14, Musk posted up a storm on Instagram, sharing a few illustrations of Red Dragon and what it would look like landing on Mars.
