  • We're going into a totally different phase of spaceThe first time it was about two

  • superpowers trying to prove their technological prowess and they set the moon as their objective

  • and then we realized. There's a lot in space that we can actually utilize. The oxygen that

  • you need, the propellant, the bricks to build a home are already there. You don't need to

  • bring it from EarthThat's the value of resources. The living off the land concept

  • is the one that we're searching for right nowThat's going to enable more exploration,

  • allow us to travel further. It has been realized not just by our own space agency, but by dozens

  • of space agencies around the world. By companies that see an opportunity here to get involved.

  • And when you get the whole world behind something like this, you know that it's time to go.

  • The Moon is shaping up to be a critical destination in the 2020s. The big visionEstablish it

  • as a celestial boomtown, where new technologies can be tested and the moon’s raw materials

  • can be harnessed to power future missionsSpace resources is anything that you can use beyond

  • earth. It could be solar power, microgravity, it could be vacuum in space, or it could be

  • something more concrete like metals, and minerals and gasses and water on the moonIn fact

  • the very first resource we utilized from space was just the view from above. The ability

  • to look at Earth has given us weather forecasting, global communications, GPS systems, the ability

  • to look at the effects that we're causing on EarthAngel Abbud Madrid has been focused

  • on the potential of space resources for decadesHe’s watched political objectives switch targets

  • from the Moon, to Mars and asteroids, and then back to the Moon. No matter the target,

  • for Angel, space resources are key if we want to explore further, and the Moon is the ultimate

  • proving groundNothing beats the Moon. You can see it every night. The rest are just

  • dots up in the dark sky. This is a place that is close, the place where we can test systems.

  • Now that the space industry is a $350 billion industrial juggernaut, with new start-ups

  • and commercial initiatives racing to land on the lunar surfaceAngel launched the

  • world’s first graduate program on space resources to prepare the next generation.

  • All of the young people feel that this is their time, this is their moon and they want

  • to be a part of itWe're definitely not just focused on the technology, because engineers

  • get really excited about developing thingsThere's a technological, scientific, economic, legal,

  • and even the psychological aspects of a new phase in space.

  • This new pivot is not about

  • extracting resources and bringing them back to Earth. It’s about creating a new manufacturing

  • pipeline off-worldEvery little bolt, every little nut, all of the human consumables,

  • all of the propellant have come from Earth, and that is extremely expensive. You look

  • at any rocket. Ninety percent of that rocket is fuel to launch the tiny little ten percent

  • that could be a satellite, could be a capsule with humansAnd so, that's not a sustainable

  • way to explore. It's going to limit us to what we can do. That is why, one of the most

  • important resources that we're going to go after is what can help us make propellant

  • in space. Ask any space resources expert and theyll likely tell you that: “water is

  • the oil of space.” Back in 2009, NASA slammed a used rocket tank near the Moon’s south pole,

  • confirming the presence of water ice and other volatiles in these permanently shadowed regions.

  • If you can recover the water, you can convert it into breathable oxygen for astronauts,

  • or split it into hydrogen and oxygen for rocket fuelThere's the idea of using the moon

  • as a refueling station. So you don't need to carry as much fuel from Earth to get out

  • of Earth’s atmosphere and gravity wellLaunch to the moon, refuel at the moon, and then

  • launch somewhere deeper in space like MarsIt is totally science fiction in reality.

  • But before we can build a lunar propellant depot, there’s a tremendous amount of work aheadThere’s

  • three things that we have to have in mind in order to extract resources from any other

  • planet. First of all, you have to know the resource that you're going to extract. Then

  • you have to know exactly if it's ice on the surface, is it snow, is it dirty ice, is it

  • below the surface, is it combined with the soilWe need to get down there and see what's

  • happeningNASA is planning to send a golf cart sized rover to the Moon for a prospecting

  • mission, dubbed VIPER.

  • Viper stands for Volatile Investigating Polar Exploration Rover. So

  • it's kind of a mouthful, but that really describes what it does. It's meant for the polar regions.

  • It's meant to drive all around for miles and miles, taking samples of what's there.

  • At the helm of VIPER’s drilling operations is Honeybee RoboticsTheyre veteran drill

  • experts and roboticists whove developed this planetary drillIn true space biz fashion,

  • it’s got an acronym too: TRIDENT, or the Regolith and Ice Drill for Exploration of

  • New TerrainsThe Trident drill has been in development for almost two decades.

  • The idea is that it's a rotary percussive drill. That means it rotates and hammers down to

  • one meter. It takes a little bites of the ground and it pulls up the sample. And then

  • the NASA instruments are going to look for water or any other volatiles that come out

  • of the soilIt's very small and compactIt has to be super dust tolerant. The moon is

  • known for being very difficult with dust. VIPER is going to last a couple of lunar days,

  • which means that it needs to survive the lunar nightSo it needs to be low power. It needs

  • to be light mass. It needs to never get stuckOnce it's in space, it's in space. You can't go

  • out and just fix it. It just has to work, and work for a really, really long time.

  • We do a lot of testing here. We take them to the farthest reaches of the earth just to

  • make sure they'll last. Through all of the testing we've done to date, we have not been

  • able to get this drill stuck, even when we've tried toNASA talks about technology readiness

  • level or TRL. TRL 6 is sort of the cusp of when something is ready to be developed for

  • flightSo, that's where we're at right nowAll the prospecting phase, technology demonstration

  • will have to be undertaken by robots. It's the cost and the extreme environment that

  • you're gonna be facing. Right now, the cost to send a kilogram to low earth orbit is about

  • $4,000. Thirty five thousand dollars to put it on the surface of the moon. Multiply that

  • by 10 or by 50 to have humansYou're looking at a place with radiation, you're looking

  • at a place that is dark, that lacks communications, so why send a human to do that job first,

  • send somebody else. And that somebody else is a rover that can tell us, okay, this is

  • what I foundOnce weve prospected and know more about the water ice, step two and

  • three in this future lunar depot plan come into playNow, you know the resources, but

  • do you have the technology to recover it, under any environment that you're going to

  • be dealing with. Within the first ten years you'll see some of the technologies to prove

  • how you can extract them. And third, you have to have a customer. As important as science

  • and technology and knowing your resources and how you're going to extract them, is everything

  • that comes around itSome of the companies that are trying to get involved in this, they're

  • asking those questions. Can I actually extract them? Is anybody interested? And is this legal?

  • I don't want to touch it if the Outer Space Treaty of 1967 tells me that no country can

  • own any piece of celestial land. You cannot own the moon. You cannot own asteroidsThat's

  • been signed by more than 100 countriesAnd so, how am I going to extract the resource?

  • Well, is there a way that without owning that object, the Moon or an asteroid, can I claim

  • a certain space, be there for a couple of years, extract whatever I have to do and then

  • leave. As of January 2020, only the United States  and Luxembourg have passed laws that

  • allow commercial companies to extract resourcesAt some point, we have to agree on thisSo

  • that has pushed efforts to bring countries together to talk about itThis is an important

  • conversation that we're trying to have, because there's some attachment to the MoonAll

  • civilizations have looked to the Moon in different ways. They see it as a place that some people

  • have religious connection to it, philosophical connections, or just, the beauty of it. And

  • so, we're going to have to agree on what's doable and what's not.

  • Now that we have the

  • vision, what will lunar robots look like in the future? And how exactly are scientists

  • going to turn the moon’s billion year old water into rocket fuelCheck out the second

  • part to find out!

We're going into a totally different phase of spaceThe first time it was about two
