Now we know how Elon Musk skeleton to get 1 million people to Mars.
At a discussion in Mexico now (Sept. 27), a SpaceX owner and CEO unveiled a company’s Interplanetary Transport System (ITS), that will mix a many absolute rocket ever built with a spaceship designed to lift during slightest 100 people to a Red Planet per flight.
If all goes according to plan, a reusable ITS will assistance amiability settle a permanent, self-sustaining cluster on a Red Planet within a subsequent 50 to 100 years, Musk pronounced during a International Astronautical Congress in Guadalajara.

“What we unequivocally wish to do here is to make Mars seem probable — make it seem as yet it’s something that we could do in a lifetimes, and that we can go,” he said.
Mars ride system
The ITS rocket will be some-more or reduction a scaled-up chronicle of a initial theatre of SpaceX’s Falcon 9 booster, Musk said. But a 254-foot-tall (77.5 meters) ITS upholder will underline 42 Raptor engines, since a Falcon 9 is powered by 9 Merlins. When total with a crewed spaceship, a ITS will mount a full 400 feet (122 m) high, Musk wrote on Twitter. That would make it a largest spaceflight complement ever built, taller even than NASA’s mythological Saturn V moon rocket.
The Raptor engine, that SpaceX recently test-fired for a initial time, is about a same distance as Merlin though 3 times some-more powerful, Musk said. ITS will therefore be an impossibly manly machine, means of lofting 300 tons to low-Earth circuit (LEO) — some-more than dual times some-more than Saturn V could lift. (That’s for ITS’s reusable version; an unessential various could launch about 550 tons to LEO, Musk said.)
The spaceship, that sits atop a booster, will be 162 feet (49.5 m) high and 56 feet (17 m) far-reaching and will have 9 Raptors of a own. The upholder will launch a spaceship to Earth orbit, afterwards lapse to make a soothing alighting during a launch site, that is now envisioned to be Launch Pad 39A during NASA’s Kennedy Space Center in Florida.

The spaceship will lift off with small if any fuel on board, to maximize a load — people, load or a multiple of both — that a qualification is means to lift to orbit. An ITS upholder will therefore launch again, surfaced with a tanker, and event with a orbiting spaceship to fill a tank.
Then, when a timing is right — Earth and Mars align agreeably for interplanetary missions only once any 26 months — the spaceship apportionment of a ITS will spin a engines on and blast from Earth circuit toward a Red Planet.
The spaceship will be means of transporting during slightest 100 and maybe as many as 200 people, Musk said. It will also expected underline film theaters, harangue halls and a restaurant, giving a Red Planet pioneers a distant opposite knowledge than that enjoyed by NASA’s Apollo astronauts, who were congested into a small capsule on their approach to a moon.
“It’ll be, like, unequivocally fun to go,” Musk said. “You’ll have a good time.”
The absolute Raptors will concede a boat to make a outing in as small as 80 days initially, depending on accurately where Earth and Mars are during a time, Musk said. That’s a flattering discerning trip; it takes 6 to 9 months for upholder to strech a Red Planet regulating now accessible technology. And Musk pronounced he eventually thinks a ITS boat will be means to cut a transport time to only 30 days or so.
There won’t be only one boat creation a journey. When a ITS is unequivocally adult and running, 1,000 or some-more of a ships will wizz off to Mars any 26 months.
“The Mars colonial swift would skip en masse,” Musk said.
This swift would land on Mars regulating “supersonic retropropulsion,” negligence down adequate to hold down gently by banishment onboard thrusters rather than relying on parachutes. SpaceX pronounced it skeleton to exam this alighting technique during the company’s arriving “Red Dragon” mission, that aims to launch SpaceX’s uncrewed Dragon plug toward Mars in May 2018.
Not a one-way trip
SpaceX also skeleton to build a solar-powered bureau on Mars that will use a CO dioxide and H2O ice in a planet’s atmosphere and soil, respectively, to beget methane and oxygen — a diesel used by a Raptor engine. (Musk didn’t plead other aspects of a Mars colony; SpaceX is concentrating on a travel architecture, logic that a colonists themselves will build many of a city they live in.)

The ITS spaceships will be refueled on Mars and will launch behind to Earth from there, definition impending colonists don’t have to stay on a Red Planet perpetually if they don’t wish to. (Getting off Mars doesn’t need a large rocket, since a world is many smaller than Earth and therefore has a weaker gravitational pull.)
“We need a spaceship back, so it’s coming,” Musk said. “You can burst on house or not.”
Each ITS spaceship will substantially be means to fly during slightest a dozen times, and any upholder should see even some-more action, Musk said. This reusability is a pivotal component of SpaceX’s plan, and should be a arch motorist in bringing a cost of a Mars outing — which Musk pronounced would cost about $10 billion per chairman regulating today’s record — down to reasonable levels.
“The design allows for a cost per sheet of reduction than $200,000,” Musk said. “We consider that a cost of relocating to Mars eventually could dump next $100,000.”
Fewer than 5 percent of SpaceX’s crew are operative on a ITS during a moment, Musk said. And a association is now spending only a few tens of millions of dollars on a plan any year, that Musk estimated would eventually need a association investment of about $10 billion.
But that should change as SpaceX wraps adult work on a final chronicle of the Falcon 9 and a crewed Dragon capsule, that will lift astronauts to and from a International Space Station for NASA (and maybe packet folks to other destinations tighten to Earth), Musk said.
Within dual years, Musk aims to be devoting many of SpaceX’s engineers to ITS, and to be spending maybe $300 million annually on a project. He envisions other organizations eventually helping SpaceX in Mars colonization as well, observant a bid will be a “huge public-private partnership.”
He pronounced he hopes to finish a initial growth of a spaceship within 4 years, afterwards start suborbital contrast shortly thereafter. If all goes unequivocally well, Musk said, a ITS could be rising on a initial Mars idea “within a 10-year time frame.”
In a meantime, SpaceX skeleton to keep rising Dragons toward a Red Planet any 26 months regulating a company’s Falcon Heavy rocket, to exam record and to settle a “steady cadence” of robotic missions that scientists could take advantage of to send experiments to Mars, Musk said.
The ITS could also be used for many other things, presumably enabling tellurian scrutiny of Jupiter’s ocean-harboring moon Europa or permitting business to fly from New York to Tokyo in only 25 minutes, Musk said. But for now, a categorical idea is colonizing Mars, that Musk has prolonged pronounced is a reason he started SpaceX behind in 2002.
“The design is to turn a spacefaring civilization and a multiplanet species,” a billionaire businessman said. “The categorical reason I’m privately accumulating resources is to account this.”
