Here it is, the grand plan for the Interplanetary Transport System (ITS) as presented yesterday at the the International Astronautical Congress (IAC) in Guadalajara, Mexico:
On Tuesday (Sept. 27), Musk unveiled SpaceX's planned Interplanetary Transport System (ITS), a rocket-spaceship combo that the billionaire entrepreneur hopes will allow humanity to establish a permanent, self-sustaining, million-person settlement on the Red Planet. Mars is the first planned stop for ITS, but it may not be the last. "This system really gives you freedom to go anywhere you want in the greater solar system," Musk said Tuesday at the International Astronautical Congress meeting in Guadalajara, Mexico. With the aid of strategically placed refueling depots, "you could actually travel out to the Kuiper Belt [and] the Oort Cloud," Musk added. The Kuiper Belt is Pluto's neck of the woods, while the Oort Cloud, the realm of comets, is even more distant; it begins about 2,000 astronomical units (AU) from the sun.
[...] The ITS booster will be the most powerful rocket ever built, capable of lofting 300 tons to low-Earth orbit (LEO) in its reusable version and 550 tons in its expendable variant, Musk said. This rocket will blast the spaceship, which will carry at least 100 people, to LEO, where further launches will fuel the smaller vehicle. When the time is right — Earth and Mars align favorably for interplanetary missions just once every 26 months — a fleet of these spaceships will depart from LEO, arriving at the Red Planet in as little as 80 days, Musk said. The ITS — both the rocket and spaceship — will be powered by SpaceX's Raptor engines, which run on a combination of methane and oxygen. Both of these ingredients can be manufactured on Mars and other places in the solar system, Musk said, meaning that the spaceship can and will be refueled far from Earth.
[...] The ITS spaceship could therefore go very far afield, provided it could access refueling stations along the way. "By establishing a propellant depot in the asteroid belt or one of the moons of Jupiter, you can make flights from Mars to Jupiter no problem," Musk said. "It'd be really great to do a mission to Europa, particularly," he added, referring to the ocean-harboring Jovian moon, which many astrobiologists regard as one of the solar system's best bets to host alien life. Building additional depots farther from the sun — perhaps on Saturn's moon Titan and Pluto, for example — could theoretically extend the ITS spaceship's reach all the way out to the Oort Cloud, Musk said. "This basic system, provided we have filling stations along the way, means full access to the entire greater solar system," he said.
The first Mars ferry will be named "Heart of Gold". Unfortunately, these bold settlers will have to be kept away from potential microbial life.

No, the other AC isn't me. I think Mars is a fine place to colonize. I don't like the Moon, though, because the only thing it has going for it is that it's close. And I actually think that is a drawback, since it encourages "test pilot thinking," in which you treat a moon base like a more difficult version of the ISS, rather than "settler thinking," in which you treat it like a place that's actually going to be a home.
Phobos and Deimos are almost nothing like the Moon. They are more like asteroids. They probably actually are asteroids, although there are dissenting astronomers on that point. They are small enough to be easy places to build (with virtually no gravity, it's easy to build underground, because you hardly need any structure to prevent a cave-in). Building underground protects you from radiation. But they are also great places to stop and refuel or repair or, eventually, do manufacturing from all the asteroid-based resources you're probably bringing back. But they're massive enough that you could attach a skyhook-style launch system to them. And doing all this construction and base-building is great practice for asteroid mining. Even with building underground to protect against radiation, you wouldn't want to live there for more than a few months because of the microgravity, but they're a great place to visit.
The Earth's moon on the other hand is more like a small planet. A planet without much in the way of resources.
