Yesterday, Elon Musk acquired on stage on the 2016 Worldwide Astronautical Congress and unveiled the primary actual particulars concerning the massive freaking rocket they’re making.

A pair months in the past, when SpaceX first introduced that this might be occurring in late September, it hit me that I’d nonetheless have particular privileges with them, sort of grandfathered in from my time working with Elon and his corporations in 2015 (which resulted in an in-depth four-part weblog collection). So I reached out and requested if I might study concerning the massive freaking rocket forward of time and write a publish about it.

They stated sure.

A short while later, I obtained on a name with Elon to debate the rocket, the timeline, and the large plan this was all part of. We began off how we all the time do.


Stick Tim and Stick Elon on the phone in silence

Then I introduced up the rocket.

Tim: The Mars rocket is big. Elon: Yes, it's quite big.


Tim: It's gonna take people to Mars. Elon: That's the plan.


Tim: I'm gonna get to go because I'm a special boy. Elon: (silence)


Stick Tim and Stick Elon on the phone in silence

Ultimately, we have been capable of settle in to a captivating dialog about this insane machine SpaceX is constructing and what’s going to occur with it.

Now, earlier than we get into issues—

This publish is simply a bit of The SpaceX Story—probably the most superb tales of our time—and a narrative I spent three months and 40,000 phrases telling final yr. Should you actually need to perceive this and also you haven’t learn that publish but, I like to recommend you begin there. The publish has three elements, divided into 5 pages:

Half 1: The Story of People and Area

Half 2: Musk’s Mission

Half three: The best way to Colonize Mars
→ Part 1: Work out methods to put issues into area
→ Part 2: Revolutionize the price of area journey
→ Part three: Colonize Mars

For many who have learn the publish and need a refresher or those that simply need to hear concerning the massive freaking rocket and transfer on with their day, right here’s a fast overview of the background:

The Context

To know why the large freaking rocket issues, it’s a must to perceive this sentence:

SpaceX is making an attempt to make human life multi-planetary by constructing a self-sustaining, one-million-person civilization on Mars.

Let’s go half by half.

Why make human life multi-planetary?

Two causes:

1) It’s enjoyable and thrilling. (Right here’s a clip from one of many interviews I did with Elon final yr the place he articulates this level.)

2) It’s not a terrific concept to have all of our eggs in a single basket. Proper now we’re all on Earth, which signifies that if one thing horrible occurs on Earth—brought on by nature or by our personal know-how—we’re accomplished. That’s like having a valuable digital photograph album saved solely on one not-necessarily-reliable exhausting drive. In case you have been in that state of affairs, you’d be sensible to again the album up on a second onerous drive. That’s the thought right here. Elon calls it “life insurance coverage for the species.”

Why Mars?

Venus is a jerk, with its lead-melting temperatures, its crushing atmospheric strain, and its insufferable winds.

The moon has few pure assets, a 28-day day, and with no environment to both present safety towards the solar through the day or heat issues up at night time, each day and night time grow to be murderous. Similar deal on Mercury.

Jupiter, Saturn, Uranus, and Neptune are simply big balls of fuel pretending to be planets.

Sure moons of Jupiter and Saturn are probably liveable, however they’re farther away and colder and darker than Mars, so why would we do this.

Pluto is even farther and colder and darker. Cease asking me about Pluto.

That leaves Mars. Mars isn’t a great time. If Mars have been a spot on Earth, it’s someplace nobody would need to go. However in comparison with all of these different choices, it’s a dream. It’s chilly however not that chilly. It’s sort of darkish however not that a lot darker than Earth. It’s far however not that far. Its day is nearly the identical size as ours, which is good for us and massively useful for rising Earthly vegetation. Its floor gravity isn’t loopy low or loopy excessive (it’s round a 3rd of Earth’s). It has a ton of (frozen) water and an honest quantity of CO2, that are crucial for early makes an attempt at dwelling there and massively useful for future makes an attempt to “terraform” the planet into a spot extra livable for people. All issues thought-about, we’re very fortunate to have an choice nearly as good as Mars—in most different photo voltaic techniques, we in all probability wouldn’t.

Why 1,000,000 individuals?

As a result of Elon thinks that’s a tough estimate for the variety of individuals you’d have to have on Mars to ensure that the Mars civilization to be “self-sustaining”—with self-sustaining outlined by Elon as: “Even when the spaceships from Earth completely cease coming, the colony doesn’t ultimately die out—which requires an enormous industrial base, and a a lot more durable industrial base to create than being on Earth.”

In different phrases, if arduous drive #2 depends on onerous drive #1 as a way to keep working, then your photograph album isn’t actually backed up, is it? The entire level of onerous drive #2 is to save lots of the day if arduous drive #1 completely crashes.

And whereas the Earth onerous drive might “crash” for a lot of thrilling causes—an asteroid hits us, AI kills us, Trump kills us, ISIS creates some upsetting organic weapon, and so on.—Elon additionally warns concerning the much less dramatic risk that the Earth ships cease coming just because Earth civilization stops having the potential to ship them:

The spaceships from Earth might cease coming for different causes—it might be WWIII, it might be that Earth turns into a spiritual state, it might be some gradual decline the place Earth civilization simply sinks underneath its personal weight. At one level the Egyptians have been capable of construct pyramids, after which they forgot how to try this. After which they forgot methods to learn hieroglyphics, till the Rosetta Stone. Rome as nicely—that they had indoor plumbing, that they had superior aqueducts, after which that fell aside. China at one level had the world’s largest fleet of crusing ships they usually have been crusing so far as Africa, then some loopy emperor got here alongside and determined that was dangerous and had all of them burnt. So that you simply don’t know what’s gonna occur. The important thing threshold to move is the variety of individuals and tons of cargo required to make issues self-sustaining. And that’s in all probability one thing like one million individuals and doubtless one thing like 10-100 million tons of cargo.

In different phrases, let’s not wait on this.

Nice, however how on earth do you convey 1,000,000 individuals to Mars?

You make this inexperienced half exist:

Blue circle: People who can afford to go to Mars. Yellow circle: People who want to go to Mars. Green intersection: At least a million people

It’s type of easy. If we get to some extent the place there are one million individuals on Earth who each need to go to Mars and may afford to go to Mars, there will probably be one million individuals on Mars.

Sadly, proper now the yellow circle is tiny and the blue circle doesn’t exist.

Elon thinks—and I type of do too—that if the blue circle can get large enough, the yellow circle will deal with itself. If Mars is reasonably priced and protected and you understand you’ll be capable of come again, lots of people will need to go.

The exhausting half is the blue circle. Right here’s the difficulty:

Final time the US Congress checked with NASA, the price to ship a five-person crew to Mars was $50 billion. $10 billion an individual. Elon thinks that to make the blue circle sufficiently giant, it must value $500,000 an individual. 1/20,000 of the present value.


That’s like wanting on the automotive business and saying, “Proper now a brand new Honda prices round $20,000. To make this a viable business, we have to get the price of a brand new automotive right down to $1.”

So what the heck?

Right here’s the heck:

Think about if the best way planes labored was that they took off, flew to their vacation spot, however then as an alternative of touchdown, all of the passengers parachuted right down to the bottom after which the aircraft landed by smashing into the ocean and blowing up. So each aircraft flew precisely as soon as, and to have a brand new flight occur, you’d need to construct one other aircraft.

A aircraft ticket would value $1.5 million.

Area journey is presently so costly principally as a result of we land rockets by crashing them into the ocean (or incinerating them within the environment).

When Elon began SpaceX, he was decided to repair this drawback. It was a tall order, provided that nobody had ever executed it earlier than—together with nations just like the US and Russia who had spent billions making an attempt. However SpaceX puzzled away on the drawback yr after yr, and after making an attempt and failing a bunch of occasions, in late 2015, they nailed it:

Then they nailed it once more. And once more. And once more. Now they nail it most of the time. Right here’s a daytime view of a current touchdown:

Quickly, for the primary time, a beforehand used-and-landed, flight-tested Falcon 9 will perform a brand new mission for SpaceX, formally making SpaceX rockets “reusable.”

To fly a mission on a used rocket, you solely have to pay for propellant (gasoline and liquid oxygen) and a little bit of routine upkeep. This cuts the worth of area journey down by 100 and even 1,000 occasions.

That leaves us with someplace between 19/20 and 199/200 of the fee left to chop. A part of that may occur when SpaceX takes 100 or extra individuals to Mars at a time, as an alternative of 5 (the quantity Congress requested NASA about). The remainder of it’s taken care of by a couple of easy improvements, like refueling the spaceships in orbit (which lowers the fee by 5-10x) and manufacturing propellant on Mars so that you don’t have to hold your return propellant with you (which lowers the price by one other 5-10x). Extra on these issues later.

All of the sudden, not solely can the worth get right down to $500,000/ticket, it will probably in all probability go even decrease (Elon thinks it might ultimately value beneath $100,000/individual). Chances are you’ll not have observed it but, however SpaceX’s improvements are within the course of of making a complete revolution in the price of area journey—a change that may open doorways we will’t think about being open at present. And when that revolution goes far sufficient, SpaceX’s imaginative and prescient of placing 1,000,000 individuals on Mars actually—truly—critically—might occur.

We’re going to Mars. And this week, SpaceX confirmed us the factor that’s gonna take us there.

The Rocket

“It’s so mind-blowing. It blows my thoughts, and I see it each week.”

Elon’s pumped. And whenever you study concerning the huge freaking rocket he’s constructing, you’ll perceive why.

First, let’s take up the problem at hand. It’s typically stated that area is tough. To today, just a few hundred individuals have been in area, just a few nations have the power to launch one thing into area, and the historical past of human area journey is suffering from tragic launch failures. Firing one thing tremendous heavy and delicate and filled with explosive liquid up by way of the environment with out something going flawed is extremely arduous.

However once we speak about people going into area, we’re speaking principally about people going into Low Earth Orbit, a layer of area between 100 and 1,200 miles above the bottom—and usually, they’re headed solely 250 miles as much as the Worldwide Area Station. The one time people have gone farther have been the small handful of People who made it out to the moon within the 1960s, touring about 250,000 miles away.

When Earth and Mars are at their closest, Mars is someplace between 34 and 60 million miles away—about 200 occasions farther away than the moon and about 200,000 occasions farther away than the ISS.

The moon is simply over one mild second away.

distance diagram of Earth and the moon with a bar representing 1 light second that nearly reaches the moon

Mars is greater than three mild minutes away.

Mars is way.

Elon likes to match the Earth-to-Mars journey to crossing the Atlantic Ocean, noting that utilizing that scale, going to the moon would solely be crossing the English Channel (and going to the ISS can be going to a dock 117 ft off the shore). Persevering with with that comparability, he says, “A rocket made to go to Low Earth Orbit and even the moon is principally like a coastal fishing vessel, in comparison with a colonial transport system that’s making an attempt to go 1,000 occasions additional.”

On prime of that, it is perhaps value it to take just a few people or a single satellite tv for pc up into Low Earth Orbit—however should you’re going all the best way to Mars, you need to take much more than that. So you need to take rather more mass, a lot additional. Multiplying the space issue by the payload issue, Elon explains that a Mars transport system “is like actually one million occasions extra succesful than what the present world launch system can do. It needs to be.”

It additionally needs to be extremely superior. Elon says, “It’s not simply greater, it must be extra environment friendly. There’s a false dichotomy on the subject of rockets of ‘small and sophisticated’ or ‘huge and dumb.’ Individuals speak concerning the ‘massive dumb booster’—that gained’t work. You want an enormous sensible booster. If you wish to construct a Mars colony, you haven’t any selection— you must make it massive and environment friendly.”

In order that’s all you must do—construct a rocket that’s one million occasions extra succesful than in the present day’s greatest rockets however who’s additionally environment friendly and sensible and a great listener.

SpaceX is constructing it. Meet the Massive Freaking Rocket.1

spacex mars rocket

Onerous to fairly perceive the bigness from that image. So let’s add in some scale:

spacex mars rocket with house and person drawn to scale

Or how about this?

spacex mars rocket shown over a football field for scale

It might barely match diagonally throughout a soccer subject with out going into the stands.

There’s additionally this:

spacex mars rocket in skyline for scale

It’s a skyscraper. Or as Elon places it, “by far the most important flying object ever.”

In yesterday’s presentation, Elon defined that this isn’t a primary crack at the way it may look, or an artist’s impression of the way it may look—it’s the way it’s going to look. That is the factor they’re constructing.

Sadly, SpaceX appears to be going by way of an existential disaster with regards to naming this factor—first it was the Mars Colonial Transporter, then (as a result of it may well go well beyond Mars) it was renamed the Interplanetary Transport System, then yesterday within the presentation, Elon stated they haven’t truly settled on a reputation but however that the precise spaceship that makes the maiden voyage to Mars is perhaps referred to as Coronary heart of Gold1—so nobody is aware of what to name it.

Which is why—till I hear in any other case—I’ll be calling it one thing Elon as soon as referred to it as: the Huge Freaking Rocket (BFR).

The Huge Freaking Rocket is freaking massive. At 400 ft tall, it’s the peak of a 40-story skyscraper. At 40 ft in diameter, a faculty bus might match totally beneath its footprint. It’s greater than 3 times the mass and generates over 3 times the thrust of the gargantuan Saturn V—the rocket used within the Apollo mission—which at present stands as by far the most important rocket humanity has made.

Right here’s the way it stacks up subsequent to a bunch of different rockets in measurement:


The distinction is much more excessive whenever you examine the rockets by what number of kilograms of payload (i.e. cargo and/or individuals) they will every take to orbit:


For comparability, SpaceX’s superior Falcon 9 rocket will have the ability to take about four tons of payload to Mars, and the Falcon Heavy—which is about to be immediately’s strongest rocket—will be capable of take about 13 tons to Mars. Elon believes the BFR will have the ability to take a couple of hundred tons of payload to Mars at first and ultimately be capable of take 1,000 tons. The absurdity of that statistic—that the behemoth Falcon Heavy can solely handle a bit over 1% of the BFR’s final Mars payload—is fairly onerous to soak up.

Now, to be clear—what I’ve been calling the Massive Freaking Rocket this entire time is definitely two issues: a Massive Freaking Spaceship sitting on prime of a Massive Freaking Booster.

diagram of spacex mars rocket. spaceship: crew cabin, cargo cabin, liquid oxygen tank, methane fuel tank, 9 Raptor engines. booster: liquid oxygen tank, methane fuel tank, 42 Raptor engines

The Huge Freaking Booster

Let’s begin by speaking concerning the booster. The 25-story-high booster—AKA the precise rocket of the BFR—is what Elon calls “fairly a beast.” It’s the most important booster of all time—by far. By bodily measurement, undoubtedly, however much more so by thrust.

Within the SpaceX submit, I talked concerning the Falcon 9’s 9 Merlin engines, and the way every one was highly effective sufficient to carry a stack of 40 automobiles up into the sky—in complete, that meant the Falcon 9 set of engines might raise 360 automobiles. The Falcon Heavy, with its 27 Merlin engines, might carry a stack of over 1,000 automobiles up previous the clouds.2

The Huge Freaking Booster sits atop a special sort of engine: the Raptor.

spacex raptor engine

The Raptor engine seems to be rather a lot like a Merlin, with one key distinction—by considerably growing the strain, SpaceX has made the Raptor over 3 times extra highly effective than a Merlin.

A single Raptor engine produces 310 tons of thrust—sufficient to raise 310 tons, or a stack of 172 automobiles, or a whole Boeing 747 airplane, into the sky. That’s what one Raptor can do.three

And the BFB has 42 of them.four

view of 42 Raptor engines

All collectively, that’s an remarkable 13,033 tons of thrust, sufficient to push greater than 7,000 automobiles—or 50 giant airplanes—as much as area.

The Massive Freaking Spaceship

So then there’s the spacecraft—which SpaceX calls the Interplanetary Spaceship, and which I’m going to maintain calling the Massive Freaking Spaceship as a result of it’s extra enjoyable. The BFS is the large cool-looking factor on prime of the BFB (in case you’re getting Huge Freaking Confused—the Huge Freaking Spaceship (BFS) on prime of the Huge Freaking Booster (BFB) collectively make what I’ve been calling the Massive Freaking Rocket (BFR)). The BFS is what is going to take the individuals and cargo to Mars. It’s additionally what is going to launch, by itself, off Mars and return to Earth with individuals who need to come again.

The BFS is itself the dimensions of a tall, 16-story constructing, and is 55 ft large at its thickest level. Along with a whole lot, and ultimately a thousand tons of cargo, the BFS will have the ability to carry as many as 100 individuals firstly, and Elon believes that quantity might develop to 200 and even above 300 individuals over time—like a cruise ship.

With 9 Raptor engines, it’ll have extra liftoff thrust by itself than any of at the moment’s rockets—together with subsequent yr’s Falcon Heavy. For a second-stage, cargo-carrying spacecraft to pack extra thrust than even probably the most highly effective first-stage rockets is outrageous.

Right here’s a cross-section up shut:

cross section of spacex mars spacecraft

I requested Elon what it’ll be wish to journey in it. He stated, “Properly, you’d be in an enormous spaceship in microgravity.5 I imply, it will be fairly enjoyable. You’d be floating round.”

Good level.

Within the presentation Q&A, he added: “It needs to be actually enjoyable and thrilling, it could possibly’t really feel cramped or boring. The crew compartment is about up so as to do zero-g video games, you possibly can float round, there might be films, lecture halls, cabins, a restaurant—it’ll be actually enjoyable to go.”

Um, yeah, get me on that factor now. A zero gravity cruise ship. With this view:


And should you have been to go, right here’s how the entire thing would work:

1) Get on the ship. The BFR shall be taking off from pad 39A at Cape Canaveral, Florida—the identical pad that the Apollo astronauts left from. It’s because that pad was constructed to be absurdly giant since they didn’t know but how massive a rocket they’d be utilizing. Whenever you get there, you head up the tower and throughout the bridge into the Massive Freaking Spaceship.


2) Take off. You strap in, and the BFR lifts off. After a couple of minutes, the first-stage BFB separates and heads again right down to Earth. The BFS that you simply’re in continues onward and settles into Earth’s orbit.


three) Refuel in orbit. After touchdown again on Earth, the BFB is capped with a brand new BFS—this one filled with propellant (liquid oxygen and methane).6 It lifts off once more and pings the propellant-filled spaceship into orbit, the place it rendezvouses7 together with your spaceship. The 2 join like two orcas holding palms because the propellant is transferred.


This occurs a number of extra occasions till your spaceship is solely refueled.eight This course of is important A) for decreasing the price of the journey, and B) for making the journey a lot quicker. Individuals have all the time thought a journey to Mars would take six or 9 months, however the BFS will get there in three.

four) Head to Mars. Three months of enjoyable occasions in microgravity and getting actually sick of the opposite individuals on the ship.9 In the course of the journey, the spaceship steers utilizing chilly fuel thrusters, powered by large photo voltaic arrays:


5) Enter the Mars environment. Time for the warmth defend to be depressing:


6) Land on Mars. Upright, the identical means the primary stage lands on Earth.

7) Reside on Mars for some time doing god is aware of what. If it’s early on within the colonization course of, you’re in all probability there to work and assist construct up the preliminary industries. Afterward, it might be something—analysis, entrepreneurship, or simply merely journey.

eight) Make propellant on Mars. This can be one of many key early industries to arrange on Mars. Propellant consists of liquid oxygen (O2) and methane (CH4), that are each conveniently straightforward to make from the huge portions of H2O (ice) and CO2 (the primary fuel within the Martian environment) already sitting on Mars. They’ll use this propellant to load up the spaceship you got here there on in preparation for its voyage again to Earth. Doing this spares the huge expense of getting to hold propellant all the best way from Earth for the return journey.

9) Both keep endlessly or come again. In the event you come again, you’ll achieve this by boarding one of many BFS’s that came to visit within the final batch.

10) Land vertically on Earth. Identical to you probably did on Mars. The spaceship will undergo routine upkeep in preparation to go again to Mars two years later.

11) Be that unbearable one that can’t be a part of any dialog with out determining some method to deliver up your time on Mars.

Mission full.

This type-of-confusing diagram sums it up:


And this video sums it up very deliciously:

In order that’s the cope with the Massive Freaking Rocket and the way it’ll all work.10

Now let’s speak about how this all may play out.

The Plan

Again to actuality. So how can we get from, “there’s this rad potential rocket that could be able to launch in 5 years” to “we’re a thriving multi-planetary civilization with one million individuals on Mars”?

10,000 flights. That’s what number of BFS journeys to Mars Elon thinks it’ll take to deliver the Mars inhabitants to one million.

Why 10,000? As a result of there shall be at the very least 100 individuals on most journeys, and that quantity will go up over time—however there may even be some individuals getting back from Mars every time different individuals go. Within the decrease a part of every BFS shall be an enormous cargo compartment. Elon thinks we’ll have to get at the least 10 million tons of cargo to Mars for the million-person colony to turn out to be self-sustaining, which can occur in a bit over 10,000 flights if SpaceX can get the cargo payload capability as much as 1,000 tons comparatively shortly, as they hope to.

And when will these 10,000 journeys begin?

Nicely let’s check out the Mars-Earth Synodic calendar—which offers with the dates when Earth and Mars are closest to one another (referred to as a “Mars opposition”). Earth’s orbit is smaller than Mars’s, so Earth goes across the solar faster—a lot so that each 26 months, Earth laps Mars they usually’re briefly subsequent to one another. That’s the one time when Earth-Mars transfers can occur.

We’re presently fairly near Mars, because the final Mars opposition occurred on Might 22, 2016. That’s why, should you occur to be an “oh look there’s a way-too-bright star let me take out my Sky Information app and work out which planet that’s after which inform everybody I’m with and discover that, but once more, nobody cares, as a result of everyone seems to be a horrible individual” nerd like me, you recognize that each one summer time, Mars has been tremendous outstanding and vibrant in our night time sky.11 A yr from now, Mars will probably be on the opposite aspect of the solar from us, and we gained’t see it in our night time sky in any respect.

The 2016 Earth-Mars opposition can also be a particular one, as a result of it’s the final time it’ll occur with out anyone speaking about it.

Why? As a result of beginning with the subsequent one in July of 2018, SpaceX will begin sending stuff to Mars every time there’s an opposition, and this can turn into more and more massive information every time. Right here’s the tentative schedule, if every thing goes completely to plan:

Upcoming Mars Oppositions – and what SpaceX is planning for every

July, 2018: Ship a Dragon spacecraft (the Falcon 9’s SUV-size spacecraft) to Mars with cargo

October, 2020: Ship a number of Dragons with extra cargo

December, 2022: Maiden BFS voyage to Mars. Carrying solely cargo. That is the spaceship Elon needs to name Coronary heart of Gold.

January, 2025: First people-carrying BFS voyage to Mars.

Let’s all return and skim that final line once more.

January, 2025: First people-carrying BFS voyage to Mars.

Did you catch that?

If issues go to plan, the Neil Armstrong of Mars will contact down about eight years from now.

And 0 individuals are speaking about it.

However they are going to be. The hype will begin a pair years from now when the Dragons make their Mars journeys, and it’ll kick into excessive gear in 2022 when the Huge Freaking Spaceship lastly launches and heads to Mars and lands there. Everybody will probably be speaking about this.

And the excitement will simply speed up from there as the primary group of BFS astronauts are introduced and develop into family names, admired for his or her bravery, as a result of everybody will know there’s an inexpensive probability one thing goes incorrect they usually don’t make it again alive. Then, in 2024 they’ll take off on a three-month journey that’ll be front-page information day by day. Once they land, everybody on Earth shall be watching. It’ll be 1969 another time.

This can be a factor that’s occurring.

Elon doesn’t like when individuals ask him about this primary voyage and the Neil Armstrong of Mars. He says that it’s not about humanity placing a brand new multi-planetary feather in its cap, and he’s fast to level out, “placing individuals on the moon was tremendous thrilling—however the place’s our moon base?” In different phrases, having humanity give Mars a excessive 5 for bragging rights just isn’t what issues—what issues is finishing up the complete imaginative and prescient of truly making a full, self-sustaining civilization on Mars.

And yeah, positive, high quality. However I’m excited for 2025. It’s gonna be so enjoyable.

Anyway, so then the subsequent Mars opposition will roll round in 2027. This time, if every thing stays on monitor, a number of BFS’s will make the trek to Mars, carrying extra individuals than have been within the unique group in 2025. And the spaceship that went over in 2025—the area Mayflower—will make its return journey to Earth, carrying a few of the first group of Mars pioneers again residence. They’ll return to large celebration as worldwide heroes, and the legendary spaceship will head off to take pleasure in its life within the Air and Area Museum.

In the meantime, we’ll all be glued to the TV12 because the group of BFS’s arrive on Mars, the place the individuals in them will proceed the grueling work began by the 2025 group. The early colonists may have a tough job like early colonists all the time do—and this might be additional arduous. Not solely will they’ve to really begin from scratch—digging mines and quarries and refineries, developing the primary underground village habitat with the primary Martian hospitals and faculties and greenhouse farms, laying down an enormous plumbing system to pump water into the village, constructing that first rocket propellant plant—however they’ll need to do all of this in a spot the place they will’t go outdoors with no spacesuit on, and the place everybody and every part they’ve ever recognized is on a pale blue dot within the sky.

It’ll be exhausting, however for the explorers of our world the payoff could also be value it. Elon says: “You’ll be able to go anyplace on Earth in 24 hours. There’s no bodily frontier on Earth anymore. Now, area is that frontier, so it’ll attraction to anybody with that exploratory spirit.”

In April of 2029, SpaceX will ship a good bigger group of spacecraft, individuals, and cargo to Mars. This time, it’ll in all probability get much less consideration. By 2029, we’ll in all probability be getting used to the concept there are individuals on Mars and that each 26 months, a terrific two-way migration happens.

The rising Mars colony will proceed to entice the adventurers—those that learn concerning the nice crusing exhibitions of the 15th and 16th centuries and yearn to be there. Once I requested Elon about how the small colony will develop and evolve, he stated: “Consider the Mars colony as an organism that begins off as a zygote, after which turns into multi-cellular, after which will get organ differentiation—so it doesn’t look precisely the identical all the best way alongside, any greater than the primary settlement in Jamestown wasn’t consultant of america right now. It’ll be the identical with Mars—Mars would be the new New World.”

The 2031 and 2033 and 2035 oppositions will convey considerably extra individuals to the brand new New World. By this level, the budding Martian metropolis might be part of our lives. We’ll comply with the Twitter feeds of a few of our favourite journalists on Mars to maintain up with what’s occurring there. We’ll all get hooked on Mars’s first hit actuality exhibits. And a few of us will begin considering, “Ought to I signal as much as go to Mars one in every of these years earlier than I get too previous?”

By 2050, there shall be over 100 thousand individuals on Mars. The corporate your son works for may need a department there, and he’ll be saying goodbye to a few co-workers who’re about to go to the planet for a 52-month stint. He tells you that he doesn’t need to go as a result of he doesn’t need to take his ninth-grade daughter away from her life and her buddies. However he says she’s making use of to a program that may convey her to Mars from the ages of 17 to 23 for an city planning diploma. You are worried, despite the fact that you realize it’s irrational. It’s simply that you simply keep in mind the times when going to Mars was dangerous and harmful, and a few a part of you continues to be uncomfortable with it. And what if she decides to not come again?

By 2065, the early days of Mars appear primitive. Through the first few Mars migrations, just a few spaceships made the journey with solely 100 individuals in every, it was prohibitively costly to go, it took three months to get there, and there have been just a few very grueling industries on Mars to work in.

In 2065, each Mars opposition sees over 1,000 ships make the journey, every carrying over 500 individuals and a pair thousand tons of cargo. Half one million individuals make the journey each two years, and about 50,000 lower than that come again, as a result of Earth-to-Mars migration capability grows a bit of bit every time as extra ships are constructed. The journey, which now takes solely 30 days, prices solely $60,000 (in 2016 dollars)—and most of the people simply repay the ticket worth with their well-paying job on Mars (labor is in excessive demand because the early Mars cities proceed to broaden and new cities are constructed).

Many individuals keep in mind these early days of the Mars colony when it was all about SpaceX—funded by SpaceX or their cargo shoppers and pushed by their ambition and their ingenuity and their guts. However now, dozens of corporations focus on Earth-Mars transit and a whole lot of corporations give attention to improvement and entrepreneurship on Mars. And transit is paid for like planes and trains and buses are paid for at the moment—by passengers shopping for tickets.

A decade later, the 2074 migration brings the Mars inhabitants above one million individuals. Small celebrations escape round each worlds, as a long-awaited landmark is achieved. Most individuals although, don’t even discover.


Every part I simply stated was based mostly on issues Elon stated on my telephone name with him. A few of it was numbers he stated immediately—just like the final paragraph, which got here from him saying, “I’m hopeful that we will get to one million roughly 50 years after the beginning.” Different occasions it was me extrapolating a attainable future, given the predictions I heard from him. It’s all based mostly in actuality. A minimum of, it’s based mostly in Elon Musk’s greatest crack at actuality. He was very cautious to qualify every little thing that appeared like a prediction or a projection with, “That is what may occur if issues go nicely—however there’s no method to know, and lots of issues might go fallacious alongside the best way.” He emphasised that “it’s not that SpaceX has all of the solutions and we’ve acquired it coated or something like that—it’s that we need to present that it’s attainable. Nevertheless it’s removed from a given.” As for issues that would go flawed, he listed off a number of (like World Conflict III), and considered one of his largest considerations is that if he someway dies younger, SpaceX could possibly be taken over by somebody who needs to exploit the corporate for revenue as an alternative of staying single-mindedly targeted on the Mars civilization mission.

But when SpaceX can handle to get this factor began, Elon thinks it might be not only a massive deal in itself, it might jumpstart a slew of latest prospects for humanity. He explains:

The large image isn’t simply to again up the arduous drive however to actually change humanity right into a multi-planetary species. Primarily what we’re saying is we’re establishing a daily cargo path to Mars. With the financial forcing perform of interplanetary commerce, there would be the assets and the motivation to massively enhance area transport know-how, and I feel then issues actually go to an entire new degree.

What I’m describing might sound actually loopy, nevertheless it truly might be a small fraction of what’s finally achieved, so long as we develop into a two-planet civilization. Take a look at delivery know-how in Europe. When all you needed to do was cross the Mediterranean, the ships have been fairly lame—they couldn’t cross the Atlantic. So commerce principally had short-range vessels. With out the forcing perform, delivery know-how didn’t enhance that a lot—you might do the identical issues with ships, just about, across the time of Julius Caesar as you possibly can across the time of Columbus. 1,500 years later, you would nonetheless simply cross the Mediterranean. However as quickly as there was a purpose to cross the Atlantic, delivery know-how improved dramatically. There wanted to be the American colonies to ensure that that to occur.

The individuals at SpaceX consider that when we’re on Mars, the remainder of the Photo voltaic System turns into accessible as properly. That’s why they didn’t simply create pictures of their Massive Freaking Rocket standing proudly on Mars. They confirmed it flying by Jupiter.


And Saturn.


And bringing human explorers to faraway moons.



They’re planning for a time when any individual can go anyplace they need in our huge Photo voltaic System—a brand new golden age for exploration, with uncharted bodily frontiers in each path.
