  • Four rooms, earth view.

  • Sounds far-fetched at the moment, doesn't it?

  • But you know we may be seeing ads like this

  • in the not too distant future.

  • Living away from earth

  • has always captured our imagination.

  • As well as providing the basics for survival,

  • these ideas are a symbol

  • of humankind's unique creativity and ambition.

  • This advanced base, or space station,

  • will be headquarters for the final ascent to the moon.

  • Today the idea of multiple outposts

  • where we can live and work in space has never seemed closer.

  • We're gonna fly.

  • It's about making our lives the best we can make it.

  • It's about as a species having a path for our future.

  • And the mission to create these habitats

  • is well underway as private companies get ready

  • to take that next giant leap.

  • The International Space Station.

  • It's the only space habitat we have.

  • One of the first places they take you in the ISS

  • is the cupola so you can finally look at the Earth

  • in all its beauty.

  • I don't care who you are, it's always stunning,

  • it's shocking, it's amazing, because that's the view

  • you've been waiting for your entire life.

  • It passes over 90% of the world's population

  • without most of us ever realizing.

  • And, at an estimated cost of a $150 billion,

  • it's the most expensive object we've ever built.

  • You think about the Sistine Chapel, the pyramids,

  • and the Burj Khalifa or take your pick.

  • I mean it far outstrips those.

  • It's the one and only non-terrestrial human outpost.

  • We've had a constant human footprint

  • in orbit for almost 20 years

  • because of the International Space Station.

  • The collaboration between 15 countries

  • started construction in 1998 and was pieced together

  • in space over the course of a decade.

  • Since 2000 it's been a permanently

  • crude research laboratory.

  • A space habitat that's allowed humankind to live,

  • manufacture, and explore beyond Earth.

  • The overarching achievement

  • of the space station has been education.

  • It has educated us about how to do research.

  • It's educated us about how to live.

  • It's educated us about the harshness of the environment

  • that it is in.

  • And it's about learning, I think.

  • People say what was one of your favorite parts

  • about being up there?

  • Hands down, floating everywhere I went.

  • Bbut your first impressions for ISS certainly is,

  • it's how big it is.

  • The ISS is the size

  • of an American football field with most of that footprint

  • taken up by eight solar arrays.

  • These provide enough energy to power 40 homes.

  • The station has an American side and a Russian side

  • as well as contributions from other nations

  • like Canada, Japan, and the European Union.

  • Astronauts on board can pass freely between these sections.

  • Their living and working areas are made up of modules,

  • each 4.2 meters in diameter.

  • And in total, they have the same volume as a Boeing 747.

  • The three main labs, Destiny, Hope, and Columbus,

  • are conducting up to 600 ongoing experiments

  • at any one time.

  • And while it's been a collaboration

  • between governments to build and maintain the ISS,

  • its next chapter will rely more on private enterprise.

  • Today's a very remarkable day.

  • NASA is opening the International Space Station

  • to commercial opportunities

  • and marketing these opportunities

  • as we've never done before.

  • Managing and maintaining the ISS

  • costs $3.4 billion a year.

  • That's over half NASA's space operations budget.

  • Aging hardware and space debris will only add to these costs

  • which is why NASA is now hoping to pass some responsibility

  • for the station over to commercial companies.

  • We would like to see a robust commercial marketplace

  • in low earth orbit where space stations exist

  • outside of NASA.

  • The goal being that NASA could be a customer.

  • And we want to have numerous providers

  • that are competing against each other

  • on cost and innovation.

  • Keep your rut, and--

  • With federal funding proposed to stop in 2025,

  • opening the station to private enterprise

  • would free up resources for the space agency's ambitions

  • to return to the moon and journey to Mars.

  • Transferring to a more commercial model

  • is allowing industry to take over many of those areas

  • that NASA has traditionally been responsible for.

  • Like the design, and operations,

  • and maintenance of space systems.

  • But the most exciting part, I think, is new opportunities.

  • The iPhones would have never come

  • from the government, for instance.

  • The base technology came from the government,

  • but the way it's used, the way it interacts with consumers,

  • governments aren't really built for that.

  • So I think that'll be exciting to see how private industry

  • uses the same technology or the same systems

  • but then use them in a different way.

  • Every NASA achievement

  • has been the collaborative achievement of NASA and industry.

  • What's going on right now that's a little bit different

  • is NASA is turning to companies,

  • not to direct them what to do,

  • but it's turning to companies to build relationships

  • with them because those companies are attracting investment

  • from non-space sources and are bringing a different kind

  • of innovation to the table.

  • In the shadow of NASA's

  • sprawling Johnson Space Center,

  • the headquarters of startup Axiom Space

  • might seem a little modest, but their goal is big,

  • to build the first commercial space station.

  • Led by a former ISS program manager,

  • the team has been involved in every mission

  • to the station since its inception.

  • We know it has to be much lower cost to operate on orbit

  • than ISS is today so this is key

  • to continuing the heritage of ISS.

  • It's to start there so we can evolve everybody

  • to the next platform.

  • I liken this to the Internet.

  • So the Internet was created, and we got very excited,

  • and any kid with a good idea

  • and just the basic programming skills

  • could go build a program to do something.

  • We have huge companies that grew out of that

  • and still today there's new ideas, new things being built.

  • The thing about a microgravity environment

  • is it's limitless.

  • It's like the data we have access to

  • on the Internet is limitless.

  • And it is not immediately obvious to us all the benefits

  • that that's gonna entail

  • but over time it will become very, very obvious.

  • By 2024, Axiom plans to send a central node

  • to attach to the ISS that will make up the core

  • of their new station.

  • This will be followed by crew quarters for 16 people

  • and research and manufacturing modules.

  • When the ISS is retired,

  • this will break away and additional modules

  • with a life span of 30 years will be added

  • and swapped out as they age using a robotic arm.

  • And they're hoping to do all of this

  • for 1/50th the cost of the ISS.

  • I mean when you talk about our vision,

  • it sounds really simple.

  • It really is about

  • driving the thought process

  • and the cost down

  • so that anybody that wants to take advantage

  • of our place in orbit

  • and a microgravity environment can do so.

  • And that's really it.

  • Okay Ellen, I need to go towards my feet.

  • The International Space Station

  • is a fantastic vehicle but one of the big things

  • is they have quite a few major components outside.

  • Which means you have to do an EVA,

  • a spacewalk, to go fix it.

  • A spacewalk on a good day is a hundred hours of crew time

  • to get ready and actually go do the spacewalk,

  • so we're able to take advantage

  • of the reduced size of components.

  • And so our design is gonna have all of the components

  • are gonna be in a pressurized environment.

  • So we know what the basics are.

  • Water, food, clothing, life support.

  • And we know how to handle those

  • but now the next step is how do we make it more intuitive

  • and we want to now take advantage of the technologies

  • and the capabilities we have today

  • to build more luxury into the experience.

  • The objective is to make the environment the background

  • for all the users.

  • You're every day doing whatever you want to do on orbit.

  • Research, manufacturing, looking out the window.

  • Whatever you're there to do,

  • we want you to be able to do that

  • and not even think about the environment.

  • And it's because of our experience on ISS,

  • and what the team brings to Axiom Space,

  • we are able to build that environment.

  • You won't worry about that.

  • Three, two, one, release, release, release.

  • Fire, fire!

  • Like Virgin Galactic and Blue Origin,

  • Axiom is hoping to attract space tourists

  • with tickets starting at $55 million for a 10-day mission.

  • But that's just one part

  • of the commercial space station market

  • that they think could be worth $37 billion

  • over the next decade.

  • Our first commercial customers

  • are countries who have astronauts in space

  • and want to expand their activity in space

  • and countries who do not yet

  • have a human space flight program

  • who want to send people up.

  • And we've now got both research and manufacturing companies

  • who want to do work with us

  • while we're at the International Space Station

  • and on our platform after it separates from ISS.

  • Human space flight is particularly exciting

  • because it's that slice of space that is really nascent.

  • It hasn't undergone the crowding that satellites have had.

  • It hasn't already had that explosive growth.

  • It's really ready for that now.

  • The first thing I'm really looking forward to seeing happen

  • is the face of our first astronauts on orbit

  • looking back down on us and knowing that we had a hand

  • in sending that person to space.

  • And ultimately the separation of ISS

  • when it's ready to be retired and de-orbited

  • and then we continue in space independently.

  • For me, that is a stepping off moment for humanity.

  • It's almost like when Neil Armstrong

  • put that first boot on the moon.

  • This will be the first time that we've gone

  • from a platform of learning how to live in space

  • to building our permanent home in space.

  • Other private companies

  • also want to use the ISS as a starting point

  • for their own ventures.

  • Bigelow Aerospace already has one

  • of its inflatable structures attached to the station.

  • And others including Sierra Nevada

  • and NanoRacks have put forward proposals.

  • Space habitats are expensive.

  • I think it's a false dichotomy to say,

  • "Okay, we're done with the International Space Station,

  • "let's move on to commercial platforms."

  • What I think is much more likely and realistic

  • and what NASA is certainly driving toward

  • is an incremental transition where commercial platforms

  • attach to the space station

  • or work collaboratively with the space station.

  • The next chapter cannot occur

  • without the active engagement of companies.

  • That said, that active engagement might not be as customers,

  • might not be as drivers,

  • it might be in service of government mission objectives.

  • We will return American astronauts to the moon.

  • Not only to leave behind footprints and flags

  • but to build the foundation we need

  • to send Americans to Mars and beyond.

  • This proposed mission,

  • along with SpaceX's own ambition to reach the Red Planet,

  • has opened up a longer term market.

  • And some companies are already thinking

  • beyond orbiting habitats like space stations

  • to actually building on the surface of other planets.

  • I was working in a firm designing skyscrapers

  • and I saw Elon and he landed his Falcon X rocket

  • in the middle of the ocean. And that, for me, was a trigger.

  • I thought, "Wow, this could actually happen."

  • And it's always been my dream

  • to put a building on the moon or Mars,

  • and if he's going at the pace he's going,

  • it could definitely happen within my lifetime

  • and I want to be the one to build it.

  • In this warehouse alongside startups

  • from across the U.S., architecture firm, AI SpaceFactory,

  • are refining the production of MARSHA,

  • a four-story structure they created for a NASA competition

  • to design the next generation of space habitats on Mars.

  • When we started designing our Mars habitat, MARSHA,

  • I think we looked at everything that had been done already

  • and kind of tossed that aside.

  • But what we were given was a set of guidelines from NASA.

  • They think the best way to build a habitat on Mars

  • or the moon is to use what they call

  • in situ resource utilization.

  • So use the materials that are there.

  • If you've seen Sci-Fi movies,

  • you might see glass and steel domes on distant planets,

  • but the reality is to ship that kind of material

  • to the moon or Mars would be so exorbitantly expensive

  • you would never be able to build in the first place.

  • So the idea is to send the 3D printing robot

  • which can then harvest the materials you find on a site

  • and build with that.

  • The reusable print material

  • is a mix of biopolymer made from recycled plastic

  • or plants like corn and sugarcane.

  • And basalt, the rock found on Mars and Earth.

  • It's the rock that gives us its incredible strength.

  • We've tested this material.

  • It's three times as strong as concrete in compression

  • and it actually has what we call it, a tensile compass.

  • It can prevent itself from being pulled apart

  • which is something concrete's not very good at.

  • You need to think at all times

  • how do you optimize the amount of material that you use.

  • And that's also why this thing is shaped like an egg.

  • And if you think of an egg,

  • it's a very structurally optimized form.

  • It's very, very thin but it provides the strength that

  • that egg needs and that's why

  • this is shaped the way that it is.

  • The egg shape

  • as well as the nested shell structure

  • also accommodates for extreme differences

  • in pressure and temperature on the surface of Mars.

  • But more research still needs to be done

  • to find out how print materials could be gathered

  • and how 3D printing would work

  • in the unique environment of space.

  • You're dealing with a completely different set of physics

  • and environments which is very harsh.

  • The cold, the low gravity, the vacuum of space.

  • And finding solutions for how to build there

  • or do anything in space

  • just requires a high degree of innovation.

  • There's no such thing as brute force when it comes to space.

  • Like you need to think about the problem,

  • find a very elegant, lightweight, cost-effective solution.

  • The next challenge is really going to places on Earth,

  • literally taking the dirt that we're finding on a site,

  • and beginning to print with the dirt.

  • We have to perfect this technology on Earth,

  • and then we go prove it out on the moon,

  • and then finally on to Mars.

  • The first customers

  • could include NASA and companies like SpaceX

  • who would lease out these structures

  • for individual missions.

  • But before that AI SpaceFactory

  • hope their technology could be monetized

  • as well as transformational here on Earth.

  • The challenges of building on Mars forced us

  • to make this jump in construction technology

  • which we can now apply on Earth to build more sustainably.

  • So rather than building with steel and concrete,

  • which are these manufactured,

  • very energy-intensive materials, to go to a site,

  • have a solar powered array

  • that would then allow our 3D printer

  • to print in the most sustainable way possible.

  • And we never would have found these ways

  • if it wasn't for the challenge of building in space.

  • Three, two, one.

  • Ignition and liftoff of the Falcon 9 to the space station

  • on the first commercial launch

  • from Kennedy Space Center's historic Pad 39A.

  • Humans have now been consistently living

  • and working in space for more than 15 years.

  • And if we want to keep that up,

  • what do habitats need to look like?

  • And frankly, they can be large or they can be small,

  • but the future of space habitats really, to me,

  • comes down to the ability

  • to persistently maintain human presence.

  • Whether that's a few people or many people,

  • that seems to be the dividing line

  • between where we were before

  • and where we want to be in the future.

  • We have to learn how to benefit from what we do on orbit

  • and bring those natural benefits back home

  • so we help ourselves out on the ground

  • while we also learn to live somewhere else.

  • And it really, at the very deepest level,

  • is about survival of our species,

  • so I get pretty excited when I spend a few moments

  • thinking about what we're off to go do

  • 'cause this really is the first step

  • to learning to live off the planet.

  • That first step is just the start

  • of our journey to create a lasting legacy in space.

  • While commercial companies may be stepping in

  • to imagine what these new space habitats look like,

  • it's what's happening inside of them

  • that may unlock the future of space industrialization.

  • On the next episode of Giant Leap,

  • we'll visit the private companies

  • who are looking to build their business

  • around manufacturing in space.

  • Using the unique properties of microgravity,

  • they plan to create new materials

  • with extraordinary qualities

  • that can't be replicated on Earth.

  • Including new manufacturing techniques

  • that could change how we build large structures in space

  • and even unlock the ability to 3D print full human organs.

  • But before low earth orbit

  • can become a new industrial center,

  • we're going to need to take another giant leap.
